This study aims at (1) developing a conceptual design for the production of synthetic gas using an optimized process configuration based upon the Koppers-Totzek gasifier, (2) advancing the concept to commercial scale employing the process configuration as developed, and (3) modifying as required and extending the conceptual design by adding needed process units for converting the synthetic gas produced to industrial fuels and chemical feedstocks. An introduction is given exploring the concept of coal gasification in four possible routes: pyrolysis, solvation, hydrogenation, and synthesis gas. Ten different processes for coal gasification are reviewed and categorized according to the heating value of the gas produced. Chapter 3 and 4 describe in detail the process design of the coal gasification unit and related facilities including coal receipt and preparation, acid gas removal, sulfur recovery, sour water stripping, and ash-water/slag handling. The economics of the goal gasification plant are evaluated by investigating investment costs, operating costs, profitability, sensitivity of product gas cost to crucial plant parameters, and the viability of the Koppers-Totzek process as compared to other competing processes. Two applications of synthetic gas are considered: industrial fuel and chemical feedstocks. The facilities for cogeneration are explored and designed to convert the medium-BTU gas into electric power for plant and residential use and steam for heavy oil recovery. Methanol synthesis and the production of chemical feedstocks and gasoline complete the chapter on coal gasification applications.
