Hyperbaric chamber manufacturer BioBarica has received approval from the United States Food and Drug Administration (FDA) for its hyperbaric oxygen therapy chambers, marking a new expansion opportunity

A hyperbaric chamber is a medical device in which the patient breathes high concentrations of oxygen through a mask in a pressurized environment at 1.45 ATA. It increases the concentration and availability of oxygen in blood plasma and generates hyperoxia that acts in all the tissues.

Following the approval, the company is starting the team-building process in the US and they are looking to add distributors who want to enter the healthcare business, with innovative profiles and ambition to grow professionally.

“The FDA registration is a great satisfaction for us. Our company was born in 2010 and since then we have grown and expanded in Europe, the Middle East, Africa, and Latin America. We finally reached the United States, which is an extremely competitive market with high standards,” said Ivo Teler, BioBarica’s Commercial Director.

“We are very happy with the growth that the company has had in recent years and we feel a great commitment to this new phase. We not only manufacture and distribute high-quality hyperbaric chambers, but we also provide medical, commercial, technical, and scientific training, and know-how to efficiently operate a Hyperbaric Oxygenation Unit or treatment center. This adds a lot of value to our activity,” added Claudio Teler, CEO of BioBarica.

“Our goal is for more physicians to incorporate the Hyperbaric Chamber so patients can benefit from this safe and effective treatment. To do this, we need to continue adding multidisciplinary professionals to collaborate with us in spreading the benefits of Hyperbaric Oxygenation in the United States,” concludes Claudio.

HyGear Asia to supply gas recovery system to Obeikan Glass Company

HyGear Asia has signed an agreement to supply its gas recovery system to Obeikan Glass Company, the largest float/coasted/laminated glass manufacturer in the Middle East.

Both hydrogen and nitrogen gas mixtures are used in float glass production as a protective atmosphere to prevent oxidation. These gases are injected into the tin bath where liquid glass is floated on molten tin.

The most common practice of the production facilities is to vent the used mixed gases into the atmosphere. However, HyGear’s gas recovery system is developed to recover the used gases, clean them and feed them back into the process.

The use of the recovery system reduces costs and improves product quality due to the increased atmosphere refreshment rate. Further to that, it reduces the environmental impact of venting particulate matter into the atmosphere.

Commenting on the agreement, Joanna Kwan, General Manager of HyGear Asia, said, “We are delighted to expand our activities in the glass industry into the Middle East region with an established company like Obeikan.”

“This demonstrates the confidence in our ability to create value in monetary terms as well as reduction of environmental impact which is key to socially responsible companies like Obeikan Glass.” 

Fayez Abdulrazzag, CEO of Obeikan Glass Company, added, “We are pleased of our cooperation with HyGear and we are confident of the technology and our decision to invest in an innovative system.”

“We have no doubt of getting the return on our investment and much more important will enable Obeikan Glass to achieve one of its objectives as to be an environmentally friendly and also green facility.”

Investigation focuses on cryogenic freezing system

An investigation into a liquid nitrogen leak at a poultry processing plant in Gainesville, Georgia, that killed six people is focusing on a cryogenic freezing system manufactured by Messer.

The US Chemical Safety and Hazard Investigation Board’s (CSB) work on the incident at the Foundation Food Group on 28 th January is ongoing, but the CSB has released some details in an update.

The incident at Foundation Food Group’s Gainesville Plant 4 occurred on Line 4, where chicken is processed, to include seasoning, cooking, freezing, and then packaging.

The system installed on Line 4 is a liquid nitrogen immersion-spiral freezer. The liquid nitrogen units were manufactured and installed by major industrial gases company Messer and are leased to the Foundation Food Group, according to CSB.

“CSB has confirmed that both the external and the interior elements of this system were manufactured by Messer,” CSB said in a statement.

“This includes the supply tanks outside, and the interior cryogenic freezing equipment on Line 4. Prior to the recent installation of this system, a different type of freezing equipment was used, which was ammonia-based. This equipment is still collocated on Line 4 adjacent to the cryogenic system and has not yet been removed.”

Liquid nitrogen was first used in Plant 4 in 2020 and some tools were found near an immersion freezer on Line 4, according to the CSB. The CSB understands that Line 4 was shut down on the morning of the incident “due to operational issues on the conveyor line”.

“We have since learned that unplanned maintenance was being conducted on Line 4,” the CSB statement said.

“The LN [liquid nitrogen] units were manufactured and installed by Messer and are leased to the Foundation Food Group. The plant had been experiencing unresolved operational issues on the chicken conveyor that appear to have resulted in the accidental release of liquid nitrogen in the flash freezing bath. Foundation Food Group maintenance personnel reported the computerised measuring system indicated a low liquid level in the immersion bath used to flash freeze the chicken products.”

The CSB continues to investigate the incident.

“Messer was notified the morning of Thursday, 28th January of several fatalities at Foundation Food Group (formerly Prime Pak Foods, Inc.) in Gainesville, GA,” Messer said in a statement to gasworld.

“Our hearts go out to the families of the deceased, and we express our sincere condolences. We understand that other employees and first responders were being treated at local area hospitals, and we hope for their speedy recovery. Messer has offered its full support to the Foundation Food Group team and is cooperating fully with the investigating authorities examining this tragedy.”

Injection of hydrogen into blast furnace: thyssenkrupp Steel concludes first test phase successfully

thyssenkrupp Steel has successfully completed the first phase of hydrogen tests on “Blast Furnace 9“ in Duisburg. In recent months, several tests on one of the 28 tuyères of this blast furnace could be conducted, while complying with corona requirements, among them some long-term tests.

The company has gained important findings in these tests, enabling it to extend the tests to all tuyères in the next step and to transfer this technology to large-scale industrial use. The injection tests are part of the company’s climate strategy with which it intends to reduce its CO2 emissions by 30 percent by 2030.

Successful development: Tests confirm suitability for industrial use

On November 11, 2019, thyssenkrupp Steel was the first company globally to inject hydrogen into a blast furnace during operation. Hydrogen replaces coal dust as additional reducing agent. The goal is to reduce CO2 emissions – for unlike carbon, hydrogen does not react in the blast furnace to form CO2, but water.

The project is funded under the IN4climate.NRW initiative launched by the state government, is scientifically supported by the BFI research institute and supplied with hydrogen by Air Liquide.

A particular focus of the first test phase was on findings on plant technology with the use of hydrogen. To this end, injection of hydrogen was tested on one of the 28 tuyères of “Blast furnace 9” at the Duisburg site.

Based on continual data collection and analyses during the 24-hour tests, the team was able to gather extensive information, for instance, on the positioning of the hydrogen lance in the furnace, on flow and pressure conditions and on the interaction between elevated temperatures and plant technology. The collected data were used to optimize the hydrogen technology with each trial. It was also possible to reach the envisaged injection volume of about 1,000 m³ of hydrogen per hour in the tests.

Dr. Arnd Köfler, Chief Technology Officer of thyssenkrupp Steel: “The development of the hydrogen technology at blast furnace 9 is an important step in our transformation towards climate-neutral steel production. That way, we are able to reduce the CO2 emissions of the conventional coal-based blast furnace process significantly. We are very grateful to the state of North Rhine-Westphalia for funding this first trial phase, which has laid the foundations for the second phase now to come. This will then be followed by the next decisive step towards climate neutrality: The construction of direct reduction plants, which are purely hydrogen-based and can be operated completely without coal“.

Technical basis for extension to all tuyères completed

In the second test phase, the tests will be extended to all 28 tuyères of the blast furnace, thus paving the way for large-scale industrial use. The focus of research will then be on the impact of hydrogen technology on the metallurgical processes in the blast furnace. The second phase is scheduled to start in 2022, somewhat later than originally planned due to the corona pandemic. While the hydrogen for the first test phase was delivered by truck, a pipeline is required for the quantities of hydrogen needed for the second phase.

The Federal Government has held out the prospect of funding for the second phase as part of the real-world laboratory program.

A preparatory agreement on the supply of hydrogen to the blast furnace via Air Liquide’s long-distance pipelines has been concluded recently. Air Liquide was already a partner in the first project phase and intends – subject to funding approval – to invest in a new pipeline connection between the blast furnace and the existing hydrogen long-distance pipeline.

Gilles Le Van, Chairman of the Management Board of Air Liquide Germany: “thyssenkrupp, and Air Liquide are working together on a lighthouse project for the hydrogen society. Together we are pushing forward the decarbonization of steelmaking – with the aim of equally addressing climate protection and international competitiveness.

This is important for North Rhine-Westphalia, for Germany and Europe, and we are proud to make our contribution. Air Liquide brings more than 50 years of experience in the field of hydrogen to our joint project work with thyssenkrupp. We’ll build on that”.

• Jan. 28, 2021
GAINESVILLE, Ga. — A line carrying liquid nitrogen ruptured at a poultry processing plant in Georgia on Thursday morning, killing six people and injuring 11 others in an accident that union officials said raised serious questions about safety protocols at the plant.
Firefighters responded at 10:12 a.m. to a report of burns at the Foundation Food Group plant in Gainesville, Ga., about 55 miles northeast of Atlanta, Zach Brackett, a Hall County fire division chief, said at a news conference.
Once there, the firefighters found a “large contingent of employees that had evacuated, along with multiple victims that were in that crowd that were also experiencing medical emergencies around the facility,” Chief Brackett said.

Five people were found dead inside the plant, and a sixth person died after being taken to the Northeast Georgia Medical Center in Gainesville, according to Beth Downs, a medical center spokeswoman. The authorities did not release the victims’ names. Mexican government officials said that two of those killed were Mexican citizens.

“Preliminary indications are that a nitrogen line ruptured inside the facility,” said Nicholas Ancrum, the vice president of human resources at the Foundation Food Group.Credit…Scott Rogers/The Times, via Associated Press
Three others were in critical condition, and five, including one firefighter, were in fair condition, Ms. Downs said. Another three who had been taken to the hospital were released, she added. All those who were hospitalized had respiratory problems.
An additional 130 people were taken by school buses to a church for evaluation by medical personnel, Chief Brackett said.
Nicholas Ancrum, the vice president for human resources at the Foundation Food Group, said that a “tragic accident” had occurred at the plant, which had been called the Prime Pak Foods plant until it was taken over this month by the Foundation Food Group, a poultry company with headquarters in Gainesville.

“Preliminary indications are that a nitrogen line ruptured inside the facility,” Mr. Ancrum said at a news conference. “Those lost today include maintenance, supervisory and management team members. Every team member is equally important to us, and our hearts go out to their families and communities who have suffered such a devastating loss.”

Stuart Appelbaum, the president of the Retail, Wholesale and Department Store Union, which represents more than 15,000 poultry workers at facilities across the southern United States, called the deadly accident “a complete and utter tragedy.”
“Had simple safety protocols been followed today, workers’ lives wouldn’t have been on the line,” he said. “The egregious lack of standards at nonunion facilities like the one in Gainesville cost essential workers their lives today.”
The plant ran afoul of the Occupational Safety and Health Administration several times in the past few years. In 2015, it was fined more than $100,000 for about a dozen safety violations, according to records. The following year, it was fined more than $40,000 for violations.
In 2017, two employees underwent amputations, including one of two fingers after his left hand got caught in machinery that he was cleaning, according to records. The other worker lost four fingers on his right hand after it got stuck in a food mixer. In 2019, the plant was fined $3,750, records said.
Mr. Ancrum said that Foundation Food had immediately evacuated 130 employees after the leak and had taken steps to protect others and the surrounding area from exposure.
“Foundation Food Group takes workplace safety very seriously and works constantly to adopt and implement the most effective safety programs available to the industry,” Mr. Ancrum said. “Until this investigation is completed, we cannot say with confidence precisely how this accident occurred.”
Liquid nitrogen is often used in poultry plants to chill or freeze chicken after it has been gutted and processed, said Edgar Fields, the Southeast Council president of the Retail, Wholesale and Department Store Union.

But when it evaporates, the resulting nitrogen gas can fill a much larger space and can rapidly displace air and the oxygen essential to life, leading to an asphyxiation hazard, said Rick L. Danheiser, a professor of chemistry at the Massachusetts Institute of Technology. Because of its low temperature, liquid nitrogen also can cause cryogenic burns on contact, he said.
In poultry and meat plants, the seals on pressurized liquid nitrogen lines must be checked routinely for leaks, union officials said.
If it turns out that the plant was cutting corners to save costs, the company should be prosecuted, said Mark Lauritsen, the director of food processing, packing and manufacturing at the United Food and Commercial Workers International Union, which represents about 250,000 meat and poultry workers.
“This should never ever, ever happen,” given how dangerous the chemical is, Mr. Lauritsen said.
The nitrogen leak was one of several deadly industrial accidents in recent years.
In April 2010, 11 people died when an explosion ripped through the Deepwater Horizon drilling rig in the Gulf of Mexico, unleashing one of the worst offshore oil spills in the United States. In May 2020, 11 people in India died and hundreds were sickened after a tank containing styrene, a liquid used in making plastics, leaked, officials said.
Other recent industrial accidents have sent thousands fleeing from their homes.
In November 2019, 30,000 people in southeast Texas were evacuated after a pair of explosions rocked the Texas Petroleum Chemical plant. And in 2017, 21 emergency workers in Texas were treated for smoke exposure after Hurricane Harvey caused fires at the Arkema chemical plant.
The deadly accident on Thursday morning was silent, at least to one employee, Maria Bonilla, 60.
Ms. Bonilla, a Salvadoran immigrant who does not speak English, was working in the marinating department of the sprawling plant. She did not hear an explosion, or a crash or screams.

“We didn’t hear anything,” she said.
She knew something was wrong only when a supervisor came running in to her department saying that there had been an accident and that everyone had to get out.
She said she and other workers had evacuated and stood outside for more than an hour, terrified.
Ms. Bonilla, who has lived in the United States for 30 years, said that she had worked in the plant for eight years.
On Thursday evening, Ms. Bonilla was the sole worker in the parking lot, sitting in the driver’s seat of her white Chevy sedan. Her son Richie Alexis Santos, 29, had come to make sure she was OK.
“Honestly, I feel that she got blessed, she’s lucky,” he said. “Because nitrogen, you can’t see it. It’s a good thing it didn’t spread around the building or we probably wouldn’t be here right now.”
He added, “Definitely it’ll be more pressure on the companies to have a safer place to work at.”
The plant is one of many in Georgia, a top chicken-producing state, and in Gainesville, which has been called the poultry capital of the world because of its many processing plants.
The industry nationwide is known for paying workers low wages to work in freezing-cold plants, where they often stand shoulder to shoulder processing birds at a rapid clip, according to the Retail, Wholesale and Department Store Union.
Workers can encounter dangerous equipment, slippery floors and hazardous refrigerants like ammonia, according to the Occupational Safety and Health Administration.

Thousands of workers have also tested positive for the coronavirus, which has swept through meat- and chicken-processing plants, many of which stayed open last year when other businesses closed.
Mr. Fields said the plants in Gainesville employ many immigrants from Asia, South America and Africa.
On Thursday evening, the Foundation Food plant was eerily quiet. Part of the parking lot was roped off with police tape. Through a doorway it was possible to glimpse an empty room lined with blue smocks for workers, hanging on a rack. Through a window could be seen an empty break room with a few lunch sacks, backpacks and bottles on a folding table.
Gov. Brian Kemp of Georgia said in a statement that “our hearts are broken after hearing about the tragedy that took place at Prime Pak Foods in Gainesville this morning.”
He said he and his family had asked all Georgians “to join us in praying for the families facing a terrible loss and the other employees who are receiving medical care.”

Investment 700 million for hydrogen research

The German government wants to turn German manufacturers into world leaders in this area. The German government has pledged to pump around 700 million euros (852 million dollars) into the field of hydrogen research by 2025, as part of plans to clean up the country’s energy landscape. 

Research Minister Anja Karliczek presented three top projects in Berlin on Wednesday, which were selected as part of a competition for state funding.

According to her ministry, they involve more than 230 partners from industry and academia.

The specific goal is to produce so-called electrolyzers, which are units that use power – ideally renewable energy – to convert substances such as water into hydrogen and oxygen.

Karliczek wants to to turn German manufacturers into world leaders in this area and she said that the nascent industry could emerge as an engine for creating jobs.

A second major project is to be dedicated to the production of hydrogen using wind energy at sea, while a third is to research infrastructure for the safe transport of hydrogen, for example via high-pressure containers or through gas pipelines.

“We want to turn Germany into the leading market and the top global supplier for hydrogen technologies,” the minister said.

She said hydrogen would be a key element of Germany’s ambitious overhaul of its coal-reliant economy as it transitions towards greener energy.

Hydrogen produces only water when burned.

The three research projects are to begin their work early this year.

Kawasaki completes world’s first liquefied hydrogen receiving terminal

Kawasaki Heavy Industries, Ltd. recently completed Kobe LH2 Terminal (Hy touch Kobe), the world’s first liquefied hydrogen receiving terminal. Kawasaki built this terminal for the CO2-free Hydrogen Energy Supply-chain Technology Research Association (HySTRA).

Operation testing has started at the facility, which will be used for a demonstration test, in a NEDO-subsidized project, for an international hydrogen energy supply chain to transport liquefied hydrogen from Australia to Japan.

Kobe LH2 Terminal (Hy touch Kobe)

Kobe LH2 Terminal consists of a 2,500 m3 spherical liquefied hydrogen storage tank with a capacity of 2,250 m3—the largest of its kind in Japan—as well as other equipment including a loading arm system specially designed for transferring liquefied hydrogen between land-based facilities and ships.

The storage tank enables stable, long-period storage of cryogenic liquefied hydrogen reduced to a temperature of -253 °C and one eight-hundredth its initial volume. The tank features a double-shell vacuum-insulation structure, comprising inner and outer shells with a vacuum-sealed layer in between to prevent heat transfer from the outside.

Additionally, the tank adopts a spherical design, which is the best shape for reducing heat transfer.

This highly reliable tank structure design is based on know-how accumulated through more than 30 years of successful operation of similar tanks Kawasaki delivered in the 1980s to the Tanegashima Space Center, operated by NASDA (now part of JAXA). Furthermore, performance tests conducted for the Kobe LH2 Terminal tank confirmed high thermal insulation capability and functional stability.

Kawasaki will utilize liquefied hydrogen storage tank technologies developed through this project to pursue even larger-sized tanks in the future, with the aim of realizing the high-volume hydrogen transport technologies necessary to achieve a hydrogen society.
