Optimize facility design with advances in air emissions modeling

B. L. Burr, Bryan Research & Engineering Inc., Bryan, Texas; K. Mach, Chesapeake Energy, Oklahoma City, Oklahoma; and A. M. Georgeson, DCP Midstream, Granbury, Texas Hydrocarbon processing systems and storage tanks are significant sources of volatile organic compound (VOC) emissions in the US. Emissions rates from process units and tanks have historically been calculated individually for permit applications and at a single operating point after design engineering is complete. Now, with the New Source Performance Standard Subpart OOOO (NSPS OOOO) rule from the US Environmental Protection Agency (EPA), operating companies must perform far more VOC emissions calculations than ever before
