ABSTRACT

This paper presents the simulation of auto-thermal ammonia synthesis reactor. Our target here

is to estimate the optimal reactor length which will give the maximum profit from the

ammonia reactor. There are many literatures which are interested in ammonia simulation in

the past but all need some corrections due to either uncorrected model used or uncorrected

algorithm. We used here the ODE45 solver of MatLab from Mathworks, along with realcoded

genetic algorithm GA and solve for every 0.0001 m from the reactor length. It is found

that no spikes, no reverse reaction can take place even at higher top temperature of 800 K. the

maximum value of ammonia objective is 5.6635e+006 at optimal reactor length of 6.4253
