Wastewater treatment manual for coal gasification-combined-cycle power plants
- CH2M Hill, Bellevue, WA (United States)
The three-volume Wastewater Treatment Manual for GCC Power Plants presents a programmed methodology for the informed user to conceive and develop, size, and cost a wastewater treatment system for the gasification and gas cleanup areas of an integrated gasification-combined cycle (GCC) power plant. Based on the limited information likely to be available at the conceptual level of GCC project development (e.g., gasifier type and coal analysis), the manual first provides information on how to characterize gasification wastewaters from moving-bed and entrained-flow gasification processes. It then provides information on applicable wastewater discharge standards and effluent reuse criteria as a means of establishing the treatment system performance goals. Given these data, the user is guided through a series of worksheets and examples in the development of one or more conceptual-level process flowsheets for an appropriate wastewater treatment system. Detailed information is provided for 28 wastewater treatment processes that may have applicability in a variety of flowsheet configurations. Another series of worksheets allows the calculation of flow and material balances that permit the conceptual-level sizing of treatment equipment. Order-of-magnitude capital and operating costs are calculated from cost curves based on these sizing criteria. Worksheets also are provided for the calculation of levelized revenue requirements, which affords a relatively fast and easy means by which to compare the costs of altemative process flowsheets. Two annotated examples are provided for the Texaco and Shell gasification processes as a means of fully conveying the manual's methodology. Each example illustrates the characterization of wastewater sources, the development of a treatment process flowsheet, sizing of the necessary equipment, and the development of cost estimates
