The study consists of three major tasks: 1. Calibrating the PC-SAFT equation of state for MEOH-CO2-H2S-H2-CO mixtures at conditions relevant for the Rectisol® process. 2. Evaluating the thermodynamic performances and optimising the energy integration of the "Reference" scheme by means of "heat-cascade" based optimisation methodology. 3. Identifying attractive process modifications on the basis of Process Integration principles.Engineering controlled termsCarbon dioxideDesulfurizationEquations of stateMethanolOptimizationThermoanalysis Coal-derived syngasEnergy integrationMethanol absorptionProcess integrationProcess modificationsSelective removalThermo dynamic analysisThermodynamic performance Engineering main headingGas absorptiontext::conference output::conference proceedings::conference paper
