ENV-99-181 Design, Operation and Performance of a Recently Installed Wet Scrubbing System at Motiva's Texas Refinery

Description:

The need to reduce SO2 emissions from the FCCU regenerator flue gas is essential for a refinery to minimize its emissions of the pollutant. In 1997 Star Enterprise Port Arthur refinery decided to minimize these emissions through the installation of a wet scrubbing system on their #3 FCCU. This paper examines the decision making process in the selection of wet scrubbing as the optimum technology for this installation. The design of the wet scrubbing system is also examined, including the specific design requirements and features for this installation. Treatment of the purge stream from the wet scrubbing system is also examined. Finally, the tie-in, startup, and performance of the system is discussed along with operating data from the system.
