A design and cost estimate was prepared for a 250 billion Btu/day lignite-to-SNG plant that uses Lurgi dry-bottom gasifiers to gasify lignite and the Texaco Partial Oxidation (POX) process to gasify the various hydrocarbon liquids produced by the Lurgi process. Also presented are plant performance and economic comparisons between this plant design and a Base Case design prepared previously in which the Lurgi by-product liquids are burned in boilers and superheaters for steam production. The cost-of-gas for the Study Case is approximately 1.5% higher than the cost-of-gas for the Base Case. It is slightly more economical to burn Lurgi liquids than to gasify them in an auxiliary unit, primarily because if liquids are gasified, additional coal-fired boilers are required for generation of process steam and these are substantially more expensive than boilers fired with liquid fuel.
