Abstract

The US EPA has proposed the Refinery MACT* rule to reduce hazardous air pollutant emissions from refinery catalytic cracking units, catalytic reforming units, and sulfur recovery units. The final rule is due July 1999. This paper presents results of a cost-benefit analysis conducted by the author while at API. The study computes emissions inventories and reductions, costs, risks, and benefits of alternative levels and forms of the FCC inorganic MACT standard*. Metal HAPs (MHAPs) and SOX emissions are simulated under alternative feed qualities. The analysis reveals the distinct possibility of higher emissions of MHAPs if the trend toward heavier, sourer cru
