Advanced coal-gasification technical analyses. Appendix 3: technical/economic evaluations. Final report, December 1982-September 1985
This document contains the final report on four tasks performed by KRSI as part of the Advanced Coal Gasification Technical Analysis contract with GRI. It provides extensive, consistent technical and economic information regarding application of (1) Lurgi gasification, (2) Westinghouse (now KRW) gasification, and (3) Direct Methanation (with Lurgi gasifiers) processes to produce SNG from North Dakota lignite. The results of Lurgi and Westinghouse studies were used to develop a plant size vs. cost-of-SNG relationship. The report on each task consists of a block flow diagram, component material balance, process flow sheets showing operating conditions and principal equipment in each major process area, a narrative process description, utility balances, plant efficiency calculations, documentation of design and cost-estimation basis and an economic analysis performed in accordance with the GRI Guidelines. Economic analysis consisted of capital-cost breakdown according to plant areas, variable operating and maintenance costs, and calculation of levelized, constant-dollar cost-of-gas with and without process development allowances (PDA). The sensitivities of the gas cost to major variables are presented in graphical form. For the plant size vs. cost-of-SNG task, similar information is provided at eight different plant capacities based on both Lurgi or Westinghouse gasifiers.
