SOx and NOx emission abatement in the FCC

摘要

Some people's offices smell like potpourri, some people's smell like disinfectant and cleaning products, and some just smell like 'new furniture'. For refinery workers, on the other hand, their place of work generally smells like rotten eggs. Delightful, right? Yes, we all know that the smell is coming from hydrogen sulphide (H2S) and is something that goes part and parcel with the oil refining industry, albeit not the nicest of smells. This article focuses on SOx and NOx abatement from the FCC/RFCC, which is not the most glamorous of topics, but an important one nonetheless. It certainly should not be overlooked, and goodness knows how anyone could avoid thinking about it while having the occasional whiff of rotten eggs-a constant reminder that our refineries are generating unwanted emissions.
