Great Plains ASPEN Model Development: ASPEN Sizing Enhancements. Final Topical Report

摘要

In preparing cost estimates for the various sections of the Great Plains Coal Gasification Plant, the equipment sizing methods for the major equipment items were checked. The sizing results obtained from ASPEN were compared with the sizing results obtained by using the Halcon SD Group's (HSD) own sizing methods and in-house computer programs. Where there were significant differences between the ASPEN sizing results and our own results, the subroutine coding was checked to determine where the differences arose. Modifications were then made to the ASPEN routines where it was thought that HSD's methods would significantly enhance the quality of ASPEN. The following ASPEN sizing subroutines were modified: (1) STW01 - ASPEN tray tower sizing; (2) SVS11 - ASPEN vertical vessel sizing; (3) SVS01 - ASPEN horizontal vessel sizing; and (4) CPVVTH - ASPEN vertical vessel/tower shell thickness and weight determination. Modifications were made to sizing calculations contained in the following ASPEN COST subroutines: (1) CPC01 - ASPEN centrifugal pump costing; and (2) CPC02 - ASPEN centrifugal compressor costing. Modifications also were made to sizing calculations contained in the following ASPEN UOS subroutines: (1) UPC01 - ASPEN pump model; and (2) UPC02 - ASPEN compressor model. A new ASPEN COST subroutine that contains sizing calculations was developed, CPC04 - ASPEN reciprocating compressor costing. 4 references. (ERA citation 10:022281)
