What is ethane?

Ethane is a colorless, odorless, and flammable gas.

Ethane is considered chemically inactive and non-toxic.

Available grades:

% 99.5 _ % 99.98

Ethane storage and transport tanks:

Ethane is charged, stored, and transported as pressurized gas in cylinders and pressure vessels with a working pressure of more than 123 times.
The maximum allowable capacity for filling ethane tanks is %35.8 of the reservoir weight.

Compatible and incompatible materials:

Ethane is not corrosive.
It’s possible to use any metal in the construction of equipment in contact with ethane.
The use of butyl rubber in the presence of ethane gas is not recommended.

GAS

S – Satisfactory for use with the intended gas
C – Conditional. May be incompatible under some circumstances or conditions Contact your Praxair representative for additional information
U – Unsatisfactory for use with the intended gas
I – Insufficient data available to determine compatibility with the intended gas
O – All nonmetalic, even those considered compatible, may be ignitable in oxygen enriched environments or in other oxidizing gases. Successful
use depends upon oxygen purity, pressure, temperature, cleanliness and elimination of ignition mechanisms. Please contact your Praxair
