Ammonia synthesis reaction
Thread Content
As we all know, the reaction for synthesizing ammonia involves the combination of nitrogen and hydrogen to form ammonia, as well as the reverse reaction in which ammonia breaks down back into nitrogen and hydrogen. It is a dynamic equilibrium that is constantly changing. In practical operations, how can we increase its reaction constant so as to boost the forward reaction and produce more of the desired ammonia? Please share your thoughts on this! !
First, control the H2/N2 ratio in the recycle gas and make-up gas to meet the requirements of the reaction； Secondly, control the temperature at the outlet of the ammonia cooling system for the circulating gas, aiming to reduce the ammonia content entering the ammonia synthesis tower as much as possible ； Thirdly, internal cooling and shock-cooling type internals are used to bring the synthesis reaction temperature close to the optimal temperature curve.
