Method for circularly utilizing cooling capacity and method for increasing yield of synthesis ammonia
TLDR
In this article, a method for circularly utilizing cooling capacity and a method to increase the yield of synthesis ammonia is presented. But, the method is not suitable for the use of high temperature semi-water gas.Abstract:
The invention relates to a method for circularly utilizing cooling capacity and a method for increasing yield of synthesis ammonia. The method for circularly utilizing the cooling capacity and the method for increasing the yield of the synthesis ammonia are characterized in that: in a method of synthesizing ammonia, semi-water gas at a temperature less than or equal to 40 DEG C from an energy section enters a spray tower of a cooling tower before entering into a compressor compressed with one section; chilled water at a temperature of 10-20 DEG C from an ion film caustic soda section is pumped to the top of the spray tower of the cooling tower through a chilled water pump and exchanges heat with the semi-water gas to ensure that the semi-water gas is cooled down to below 33 DEG C and then enters into the compressor compressed by one section; the chilled water coming out of the bottom of the spray tower of the cooling tower is pumped to an ammonia cooler through a water recovery pump and cooled to be 10-15 DEG C for chlorine cooling use at the ion film caustic soda section; therefore, the yield of the synthesis ammonia is increased while the cyclic utilization of the cooling capacity is realized.read more
