4.4.3 Valve equations Simple linear opening type valves are used for the simulation of the adsorption stage experiments, so that the valves themselves do not impose a significant additional pressure drop on the flow, and the breakthrough patterns are analyzed primarily based on the pressure drop constraints, which are measured by the pressure sensors in the test facility. Equation (4.33) shows the flow model for the valves (Pahinkar et al., 2015), whereas the values for the valve time constant CT and flow coefficient, Cv are listed in Table 4.2. mv Vp,actual Cv P dVp,actual dt CT Vp,assigned Vp,actual 4.4.4 Source and sink models (4.33) Source and sink models, which simply list the feed and outlet pressures, gas inlet and outlet temperatures, and feed composition are also incorporated and connected with the valve models. The outlet pressure is atmospheric pressure, while the inlet pressure is chosen based on the experimental value in the test matrix. The feed and purge gas compositions are the same as the feed (80% He, 10% N2, 10% CO2 by volume) and purge cylinder (pure He) chosen for the experiments. 4.4.5 Simulation procedure The models for the components, shown in Figure 4.5, are coupled with each other by equating the corresponding flow variables (pressure, mass fraction, mass flow rate and enthalpy). The operation of a single solenoid valve in the test set-up is simulated by simultaneous operation of valves 1 and 2 at the inlet. The model is implemented and solved in gPROMS ModelBuilderTM, while the gas thermo-physical properties are 128PDF Image | TEMPERATURE SWING ADSORPTION PROCESSES FOR GAS SEPARATION
