Title: Systems studies of coal conversion processes using a reference simulator. Quarterly report, October 1, 1978--December 31, 1978

Abstract

Work was completed on the coding and testing of the plant cost estimation package PCOST. Significant effort was expended in adapting the ORNL PRP evaluation program to make it compatible with PCOST. Continuing efforts include completion of the user's manual and rechecking of the cost data base entries. Continued miscellaneous revisions and additions arising from user suggestions were made to the S4 and PPROPS packages. The two phase flash routine was modified to more efficiently accommodate single components. The three phase flash routine was revised to include generation of sharper initial estimates and phase stability tests. A versatile process utilities section model was implemented and tested. This program will perform the balance calculations, will select turbine design conditions, and will determine required auxiliary boiler loads for a plant steam system containing multiple steam pressure levels. Integrated simulations of the hydrogen and vapor recovery sections have been assembled and design case studies are in progress. The integrated simulation of the hydrotreating, acid gas removal, and hydrogen plant sections is being prepared for combined execution using the hierchiacal strategy tested in the previous quarter. Alternate numerical methods are being tested for accommodating the severe stiffness which has been encountered in the differentialmore » equations of the lift tube model.« less
