K. DIKSHIT S. RAY M. BANDYOPADHYAY Indian Institute of Technology, Kharagpur, India The first part of this article presented a general-purpose linear programming model and applied it to an existing petroleum refinery in India to evaluate the impact of imposed maximum SO<SUB>2</SUB> emission limits on operations and profitability. The present study presents two-step solution methodology designed to minimize SO<SUB>2</SUB> emission rates while preserving refinery profit. The proposed two-step procedure identifies an alternate solution of the LP model leading to an operating plan with maximized profit and minimized SO<SUB>2</SUB> emission rates. The study also shows that the alternative of increasing low-sulfur crude processing for lowering the total SO<SUB>2</SUB> emission rate may be effective only up to a certain proportion of the low-sulfur crude.
