The pressure swing adsorption (PSA) process is one of the potentially viable options for CO<inf>2</inf> capture from large CO<inf>2</inf> generating sources. The operating cost of a PSA process for CO<inf>2</inf> capture is mostly contributed by the operation of blowers and vacuum pumps. Hence, how to reduce the operation cost of blowers and vacuum pumps is(More)
The Catofin propane process is an emerging industrial process for propylene production through dehydrogenation of propane. It is composed of multiple adiabatic fixed-bed reactors which undergo cyclic operations where propane dehydrogenation and catalyst regeneration alternate over roughly ten minute period for each. One of the major concerns in the(More)
— A two-tier optimizing control strategy of a simulated moving bed (SMB) process has been studied on the basis of repetitive control. Repetitive model predictive control (RMPC) of product purities is carried out in the lower tier and the optimum feed and desorbent flow rates and the length of switching period are determined in the upper tier. Both of them(More)
The CATOFIN process is a propane dehydrogenation process for production of propylene. It is composed of multiple adiabatic fixed-bed reactors where dehydrogenation and regeneration (decoking) are performed alternatively over roughly ten minutes of period for each operation. In the industrial CATOFIN process, the main concern is to maintain the reactor(More)
