Control of Catalytic Fixed-Bed Loop Reactors
From Fachgebiet Regelungssysteme TU Berlin
Abstract
An application of catalytic fixed-bed reactors is the combustion of VOCs (volatile organic compounds) in industrial exhaust gases. This requires reactor temperatures above a certain ignition level. For the sake of energy efficiency, an auto-thermal mode of operation is desirable. In cooperation with the PCF group, we are investigating the control of a specific reactor configuration, the so called loop or simulated moving bed reactor (SMBR), where several feed locations can be realized using switching valves. We are mainly interested in robust switching schemes that ensure auto-thermal operation even in the presence of disturbances in the feed concentration and the gas flow velocity. An additional requirement is the prevention of local overheating which could damage the catalyst.
