Embodiment Construction
[0012] Further describe the present invention below in conjunction with embodiment and accompanying drawing thereof:
[0013] The method for separating ammonia designed by the present invention (abbreviation method, see figure 1 ,exist figure 1 Among them, the solid arrow line is the process flow of the production stage, and the dotted arrow line is the process flow of the production preparation stage). This method includes the production preparation stage (catalyst heating and reduction stage) and production stage (ammonia separation stage), and the process flow is as follows:
[0014] The production preparation stage of the method of the present invention refers to the stage of temperature raising and reduction of the catalyst that needs to be carried out before normal production. This stage is to use the hydrogen in the cycle gas to reduce the catalyst (the main component is iron oxide) in the synthesis tower to a catalyst with catalytic activity (α-Fe), and it is necessar...
