Off-Gas Processing
Minimize emissions from off gases
Off-gases formed at refineries often contain components such as diolefins, olefins, CO2, CO, hydrocarbons, H2S, and various organic sulfur species – all of which are harmful to the environment and subject to increasingly stricter regulations.
At Topsoe, we provide a wide range of proven technologies that minimize emissions from off-gases and even convert the undesired components to high-value products. The result? More cost-effective compliance with environmental legislation.
