Abstract

In this paper, we propose a strategy for optimal and safe operation of an adiabatic indirect cooled reactor (AICR) for Power-to-Ammonia (P2A). The intermittent nature of renewable energies requires P2 A plants to operate over a wide operating window between 30% to 130% of the nominal load. We formulate a rigorous transient model of a threebed AICR in an ammonia synthesis loop. The AICR operating conditions are optimized over the entire operating window. We set up a simple MIMO control structure for flexible operation of the AICR. This uses decentralised PI loops for regulatory control with setpoints from a supervisory optimisation over the operational window. The control structure is tested under extreme load variations and displays good performance.
