Characteristics Dynamics and Control of Oxidative and Coupling Methane Catalytic Membrane Reactor

Abstract

Oxidative and Coupling Methane (OCM) can be a promising technology for converting natural gas to Ethylene. Ethylene itself is an intermediate polymer product which is widely used for various needs of the chemical industry. The Oxidative and Coupling Methane reactor is currently in the researched to produce the most favorable conditions. The reactor configuration that is currently the most advantageous for application to oxidative and coupling methane reactors is the dual catalytic membrane reactor. This research is about controlling Methane and Ethane conversion systems in natural gas to produce Ethylene with the greatest conversion, determining the best tuning parameters for the three control structures, and comparing the three to get the best control arrangement. For this reason, control simulations are carried out on 9 controlled variables using three control structures, namely Proportional-Integral, Proportional Integral-Derivative, and Predictive Control Model. The disturbances given in this study were + 20% and −20% in the composition of the feed flow operating conditions (temperature, pressure, and flow rate). A comparison of the IAE values of each controller is used to determine the best controller configuration.
