Types of Gases & Their Contaminants: Crude oils contain up to 4% wt sulfur, and the gas streams produced by distillation or conversion (cracking) contain significant quantities of hydrogen sulfide (H 2 S). This highly poisonous and corrosive and odorous compound must normally be removed from the gas before it can be burnt in the furnaces. Apart from H 2 S, LPG (propane and butane) also contain carbonyl sulfide and mercaptans, and these too may have to be removed, because upon combustion they get converted in SO 2 /SO 3 , which has a major environmental impact (Acid Rain).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
