Development of SRC-I product analysis. Volume 3. Documentation of procedures
This section documents the BASIC computer program written to simulate Wilsonville's GC-simulated distillation (GCSD) results at APCI-CRSD Trexlertown. The GC conditions used at APCI for the Wilsonville GCSD analysis of coal-derived liquid samples were described in the SRC-I Quarterly Technical Report, April-June 1981. The approach used to simulate the Wilsonville GCSD results is also from an SRC-I Quarterly Technical Report and is reproduced in Appendix VII-A. The BASIC computer program is described in the attached Appendix VII-B. Analysis of gases produced during coal liquefaction generates key information needed to determine product yields for material balance and process control. Gas samples from the coal process development unit (CPDU) and tubing bombs are the primary samples analyzed. A Carle gas chromatographic system was used to analyze coal liquefaction gas samples. A BASIC computer program was written to calculate the gas chromatographic peak area results into mole percent results. ICRC has employed several analytical workup procedures to determine the amount of distillate, oils, asphaltenes, preasphaltenes, and residue in SRC-I process streams. The ASE procedure was developed using Conoco's liquid column fractionation (LC/F) method as a model. In developing the ASE procedure, ICRC was able to eliminate distillation, and therefore quantify the oils fraction in one extraction step. ASE results were shown to be reproducible within +- 2 wt %, and to yield acceptable material balances. Finally, the ASE method proved to be the least affected by sample composition.
