Carbonyls are generated in the Steam Crackers during the production of base petrochemicals.
The impurities include CO2, H2S, COS, RSH, acetylenes, dienes, NH3, O2, NOx, HCN, PH3, Hg and arsine. Proper placement and sequencing of the contaminant removal equipment is critical to ensure the most economical and reliable approach to contaminant removal.
