Linear programming (LP) models were developed for five refineries representative of the California refining industry and validated against historic operation. Process options to reduce gasoline and diesel contaminants were selected and represented in the LP models. Costs were estimated to separately reduce aromatics levels in automotive gasoline, aromatics in diesel and sulfur in diesel for 1991 and 1995. Cost impacts were scaled up to obtain the overall cost impact in California. Estimates were made of total aromatics and benzene levels in gasoline and of sulfur, aromatics and cetane levels in diesel. Estimates were made of the impact on refinery emissions, automotive emissions and automotive performance. The cost to reduce diesel sulfur level to .05% was 6.3 cents/gallon. The cost to reduce diesel aromatics level to 10% was 27.6 cents/gallon. The cost to reduce gasoline aromatics levels by 18% was 7.0 cents/gallon.
