A tubular fixed-bed reactor filled with solid sorben consisting of zeolite pellets is considered for removing carbon dioxide from biogas to produce biomethane. To generate biomethane continuously, three batch<\/em> reactors are operated in coordinated cycles. The control system has a two-level structure: a high-level coordination algorithm determines the transition from one process step to the next for each reactor and calculates references for the low-level controllers of each reactor; the low-level controllers adjust process variables, such as inlet gas flow rate, inlet or outlet gas pressure, and sorbent temperature, according to the references.<\/p>\n In this work, we first model the batch<\/em> process by conservation equations of mass, energy and momentum. Concurrent adsorption of methane is also taken into account. The model parameters are identified by a two-step procedure, using experimental measurements from two plants: one laboratory-scale (located in Piacenza) and one pilot-scale (located in Camposampiero). Using the identified model, a control system is designed to coordinate three batch<\/em> reactors.<\/p>\n","scarica_file":false,"link_estreno":[{"link_text":"Download Memory","link":"https:\/\/ieeexplore.ieee.org\/document\/8795932"}],"button":{"text":"","link":""},"referente_group":false,"data_emissione":"2019-06-28","autori":"L.
