Lignite-to-Methanol: An Engineering Evaluation of Winkler Gasification and ICI Methanol Synthesis Route. Final Report

摘要

The objective of the work reported herein was to develop a preliminary conceptual design, capital requirements, and product cost for a lignite-to-methanol plant incorporating Winkler Gasification Technology and ICI Methanol synthesis. The lignite-to-methanol complex described herein is designed to produce 15,000 TPD of fuel grade methanol. The complex is designed to be self-sufficient with respect to all utility services, offsites, and other support facilities, including power generation. Following is a summary of the results of the study: (1) Tons per day (TPD) of Lignite Feedstock and Fuel (as received) was 47,770; (2) TPD of Fuel Grade Methanol Product was 15,000; (3) Thermal efficiency, % (HHV) was 47.4; (4) Plant investment expressed in terms of first quarter of 1980 was ($ Million) 1545; and (5) Applying the economic premises used by EPRI for fuel conversion plant utility type financing, the calculated levelized and first year product costs are included.
