METC/Shell Cooperative Agreement CRADA 93-011 high temperature high pressure filtration and sorbent test program. Volume 1, Final report

In conjunction with shakedown, operation, and desulfurization testing at the Morgantown Energy Technology Center (METC) 10 in. Fluid Bed Gasification and Cleanup facility, a series of tests was completed in cooperatation with Shell Synthetic Fuels, Incorporated to obtain data relevent to the design and operation of dry particulate solids filters, and Nahcolite as a chloride removal sorbent. Shell Synthetic Fuels Incorporated provided 60 mm O.D. {times} 40 mm I.D. {times} O.5 m long silicon carbide, LayCer{trademark} 70/3 candle filters for use in filtering coal gas from the METC gasifier. METC installed the filters in a vessel existing in the METC Cleanup Facility and provided process data in exchange for ceramic filter and ash/char characterization. Details of the cooperative research and development agreement (CRADA) are found in CRADA 93-011. This report contains METC`s contribution to CRADA 93-011. Seven gasifier runs were conducted over an eighteen month period to accumulate 868 hours of operation. During this time, 3 filters were used 2 at a time to give individual candle usage of 254 hours, 525 hours, and 868 hours, respectively. During one 89 hour test, one Laycer 70/3 candle was installed with a 3M ceramic composite filter. The face velocity through the candles was maintained nominally at 2.5 ft/min throughout the testing
