Composition of refinery waste gas
The components of the waste gas produced in the production process of petrochemical enterprises are relatively complex, mainly including particles, sulfur compounds, nitrogen compounds, carbon monoxide and organic compounds, which constitute the main air pollution sources through a certain arrangement and combination.
(1) in the process of petroleum refining, a large number of toxic and harmful substances, such as sulfur dioxide, hydrogen sulfide, mercaptans, thioethers, hydrocarbons, amines and so on, will be produced in crude oil after heating, pressurization, catalysis and other processes. Most of these substances are odorous substances, some of which are not smelly, but do great harm to human body.
(2) refinery acid waste gas is a byproduct in the process of petroleum refining. Its composition includes: methane, propane, propylene, hydrogen sulfide, isobutane, etc. Its hydrogen sulfide volume accounts for the largest proportion.
