生物沼气加压水洗过程厂级动态控制设计与模拟

Dynamic control design and simulation was used to study biogas pressurized water scrubbing processes. A steady state simulation system was established using Aspen Plus software following the requirements of these processes, and the operating parameters under steady state and different operation conditions was optimized. Dynamic control schemes were also designed to ensure the biogas purification efficiency over 97%. A dynamic process simulation system was established with Aspen Dynamic model, and system performance was tested by introducing biogas intake flow disturbance and composition disturbance. Both simulation and experimental results show that the system has good dynamic response. Meanwhile, the system can effectively undertake various disturbances and ensure CO ₂ removal rate over 99.8%.
