Houston Area Medium-Btu Coal-Gasification Project Feasibility Study. Final Report. Volume III. Facility and Distribution System Design

摘要

The primary objective of the Houston Study design effort was to develop technologically feasible designs for the gasification facility and product distribution system in sufficient detail for preparing a +-25% cost estimate. The design is based on a nominal production of 125 billion Btu/day of hydrogen and syngas with key support facilities designed to accommodate expansion to 250 billion Btu/day. Production is based on using Texaco gasifiers to process Illinois No. 6 coal barged to the site. A 2800-acre site located about 4 miles north of Texas City and 32 miles southeast of Houston was selected as best suited to accommodate the facility and service the defined market. In addition to environmental and socioeconomic studies, the site was evaluated for conduciveness to construction and operation. Preliminary plot plan studies indicate that only 800 to 1000 acres will be required for the facility. The facility and distribution system costs were developed based on factors associated with this site. The facility consists of 31 individual plants; thirteen comprise the basic processes for converting coal to gaseous products, and eighteen are support systems. The distribution system follows existing pipeline corridors and is designed to accommodate expansion to 250 billion Btu/day. Volume III summarizes the design effort including process selection rationale and sensitivities, and defines the design used as a basis for the cost estimate. 66 figures, 56 tables.
