Dynamic Simulation and Sensitivity Analysis of an Ammonia Synthesis Reactor
Abstract
Ammonia reactor as the heart of an ammonia synthesis plant dominates the overall plant production. In Kellogg process, the reactor consists of four catalytic beds filled with magnetic Iron oxide and a heat exchanger on its top. The process uses quench flows in order to restrain the temperature along the beds. In this work, dynamic behavior of the reactor was investigated via dynamic simulation, assuming a quasi-homogeneous model of the reactor. Sensitivity of the output flow temperature from the beds to varying quantities of quench flows feeding the beds was also studied.
