摘要

This report documents Process Development Unit P-99's experience with solid deposits in various items of equipment. Analysis of this information indicates that coke formation in the dissolver has occurred mainly for two reasons: (1) mechanical problems which prevented normal slurry and gas flows through the dissolver; or (2) feeding low reactivity coals. After an on-stream period, a small amount of coke is always found in the bottom of the dissolver. This coke probably forms in regions of low turbulence near the dissolver inlet. The other area which most consistently has shown a tendency for solid deposits is the hot high-pressure separator. Coke formation in this vessel appears to be related to vessel design, operating temperature, and the constantly varying slurry level in the vessel which results from the oscillatory operation of PDU P-99's let-down valves. Solids found in other locations have been identified as: (1) coke that had formed because of localized overheating; (2) salts, such as ammonium chloride, that had crystallized in the process gas lines; or (3) corrosion products.
