Abstract

The purpose of this paper is to present the program objectives and non-proprietary results of the high temperature, high pressure filtration work done under the Shell/METC Cooperative Research and Development Agreement (CRADA) 93-011. The primary purpose of this CRADA was to collect data relevant to the design and operation of dry particulate solids filters employing rigid ceramic (silicon carbide) filter elements in a gasifying environment at conditions of commercial interest; e.g., temperatures up to 1100 {degrees}F and system pressures between 300 and 350 psia. Shell provided the ceramic filter elements and evaluated the exposed filter elements. METC installed the filter elements and operated their 10 inch Fluid Bed Gasification and Cleanup facility as required for their Hot Gas Clean-up Test Program. Filter elements were removed from service after approximately 254, 525 and 868 hours of on-line operation. The exposed filter elements were analyzed and compared to an unexposed element with respect to changes in physical property.
