Quizplus · Accepted Answer

Amine units are used to remove H₂S and CO₂ in refineries, but mercaptans are also commonly removed through this process. Mercaptans are sulfur compounds that can cause corrosion and foul odors, so it is important to remove them from process streams. Therefore, option C is the correct choice. Options A and B are not correct because they do not match the compounds typically removed by amine units, and option D is too broad and open-ended to be correct.
