Description

Refinery Off-Gas refers to the mixture of gases generated during the refining of crude oil. It is a by-product of various refinery processes, such as hydrotreating, catalytic reforming, and fluid catalytic cracking. The composition of refinery off-gas varies depending on the crude oil processed and the specific refining operations, but it typically includes components like methane, ethane, ethylene, hydrogen, butanes, butylenes, and other hydrocarbons[1]. 

The following table shows a typical ROG composition[2]:
