Dynamic Behaviour of an HMR Pre-Combustion Gas Power Cycle

Abstract

This paper explores dynamics for control design of a Hydrogen Membrane Reformer (HMR) pre-combustion gas power cycle. For this type of reforming to be competitive to power generation with carbon capture, low costs and emission of CO2and NOxis required. Further, high operability and robustness is also required. This is achieved through an understanding of the system dynamics and robust control structure design. The paper presents a new dynamic model of the system which is validated against a static model and is the first analysis of dynamic behaviour of the HMR pre-combustion gas power cycle. The paper identifies important dynamic features of the reformer unit and focuses on the responses in outlet temperature and hydrogen concentration of the HMR unit to changes in important candidate inputs. An initial control study explores a simple control scheme for handling important disturbances like feed changes and load changes.
