During the period December 1 to 31, 1983 work on this project was reduced in order to prepare papers for and to attend the Systems Simulation Symposium held in Morgantown, WV, and also because of the vacations and holidays that fell during this period. A limited amount of work was performed on 2 tasks. Task No. 1, Simplified Model and Task No. 4, Rigorous Models (Area 4600-Phosom). The Phosam system uses phosphoric acid to absorb ammonia which is stripped from the sour water. While it would be ideal to simulate the ammonia/phosphoric acid/water system using ionic equilibrium models, this is not possible; therefore, the approach taken is to use the Peng Robinson equation of state of the vapor-liquid equilibrium calculations. In order to use the Peng Robinson correlations, and since phosphoric acid is not in the data bank, a series of DRS runs were made to establish critical pressure, acentric factor, water/phosphoric acid interaction parameters, ammonia/phosphoric acid interaction parameter, ideal gas heat capacity, and Antione coefficients. Attached are listings of input files and reports for DRS runs. A progress report is presented on the work to date on installing a rigorous gasifier model in ASPEN.
