摘要 In this work, Aspen plus simulation software was used to develop a model to describe water gas shift (WGS) reactor systems which were validated with experimental data. The WGS reactor structures, single and two, were investigated. Based on the WGS reactor systems model, an optimization method was formulated and performed to minimize the reactor volume. This was achieved by varying reactor inlet temperatures and feed compositions and CO conversion while maintaining the hydrogen flow rate (2.2 kW PEMFC used) and CO concentration constraint 20 ppm. The results show that two WGS reactors in series systems with intercoolers largely reduced the reaction volume when CO conversion exceeded equilibrium conversion. Then, a design heuristic was built to provide a quick determination of WGS reactor system flowsheet. After sensitivity analysis was made, control structures were explored. The result shows single WGS reactor system has a larger operability range than two WGS reactors in series during hydrogen throughput changes. Operability range of two WGS reactors in series systems was reduced by an increasing inlet CO composition.
