A first-pass design and cost estimate was prepared for a plant to convert lignite to substitute natural gas (SNG) using Lurgi dry-bottom gasifiers to gasify the coal and the KRW fluid-bed gasifiers to gasify the coal fines. The overall plant thermal efficiency is between that of the Lurgi and KRW base case designs. The study-case design is of commercial interest compared to a Lurgi plant when the Lurgi plant coal fines cannot be sold. The study case is more capital-intensive because it requires more-expensive boilers and more of different types of process units than either base case. There is no advantage over a KRW plant design that provides a 30% lower cost of gas.
