I would like to ask how waste gas from current refineries and catalytic hydrogenation is treated?

How are refinery exhaust gases typically treated these days? Are they burned in the atmosphere, or is some other technology used for their treatment? Thank you
Depending on the volume of refinery gas and the analysis of its components, the possible treatment methods include: 1. Desulfurization and purification treatment； 2. Stabilize absorption in coking or catalytic processes to recover LPG components ； Check that the volume and pressure level of the refinery gas match the excess capacity of the catalytic or coking compressors ； 3. Recover H2 to reduce the hydrogen production load ； 4. Recover C1C2 as a raw material for hydrogen production ； 5. Some of the overhead gases from high-pressure hydrogenation can be used directly as supplementary hydrogen for other hydrogenation units in the plant at lower pressures; the feasibility is determined by factors such as hydrogen partial pressure and quantity. It's a general statement for reference only.
