Phase Equilibrium Data for Coal-Derived Liquids: Mixture of Model Compounds. Subcontracted R and D Final Report

摘要

ICRC initiated a test program to develop VLE and enthalpy data on selected model compounds and on well-defined coal liquids. The results obtained from the model compounds would be used to improve existing correlations in their application to coal liquefaction equipment design. The data on the coal liquids would be helpful in optimizing the design and operation of the corresponding equipment in the SRC-I Demonstration Plant. The overall test program was divided into four tasks: (1) Sample Acquisition and Preparation, (2) VLE Measurements, (3) Enthalpy Measurements, and (4) Analytical Characterization. Tasks 1 and 4 were performed by Air Products and Chemicals, Inc. (APCI). Task 2 was contracted to Chromaspec Corp., and Task 3 was performed by Colorado School of Mines (CSM). The ICRC work at Chromaspec was divided into two phases: the first phase covered VLE measurements of model compounds and coal liquids in the presence of hydrogen-rich gas at demonstration plant operating conditions; the second phase reported herein, covers VLE measurements on mixtures of polar model compounds. The results of the VLE measurements on mixtures of model compounds are presented in the attached Chromaspec report. The timing of the availability of results from Chromaspec did not permit incorporating them in the correlation development work at APCI. In spite of the schedule, the work at Chromaspec was continued so that the experimental setup could be fully utilized to develop all the necessary VLE data on the coal liquids and model compounds. 4 references.
