What is the general composition of acidic gases in refineries?

Gentlemen, what is the composition of acidic gases in refineries?
Refineries generally have two types of acidic gases: one is the acidic gas generated during liquid-rich regeneration, which mainly consists of H2S and CO2 ； One type is the acidic gas produced by wastewater stripping, mainly consisting of H2S and NH3, which are the key components; I hope this helps you.
Are there specific compositions (by volume or mass) for these two types of acidic gases?
The desulfurization gas is primarily composed of hydrogen sulfide, with a concentration generally above 50%, and in some cases reaching around 90%; there are also cases where the concentration is below 50%. The composition varies from plant to plant. Carbon dioxide constitutes the main component in other cases, along with about 1% hydrocarbons. Aminic gases mainly consist of hydrogen sulfide, ammonia, and water vapor, with each generally accounting for about 1/3. All of the above refer to volume ratios.
Agree with the answer from the second floor. In general, it is known what components are present in acidic gases, but there is not much detailed analytical data available.
