The Pall Rigimesh Backwash filter system, shown here, is similar to that which will be installed at the Phillips Borger refinery.IN DECEMBER 1998, PHILLIPS PETROLEUM CO. PURCHASED A new filter for its 60,000 b/d atmospheric resid-desulfurization unit in the Borger, Tex., refinery from Pall Corp.
The Rigimesh Backwash filter will be installed upstream of the guard reactor.
The filter installation is expected to be complete in July 1999. The purchase is a result of an extensive research and development program that the Phillips Borger complex began in 1995. Phillips and Pall worked together to fine-tune the operating parameters and design features of the filter system for this application.
The filter system is fully automated with proprietary gas-assist cleaning of the porous metal-filter elements. The new filter unit is expected to increase the run time between turnarounds of the desulfurization unit by reducing the quantity of suspended solids in the feed. Reduced particulate contamination will extend the life of the catalyst in the unit.
Other expected benefits include lower maintenance costs and reduced energy consumption.
