Does the gas head fertilizer have a nitrogen compressor?
Thread Content
Dear sea friends: I went to Linggu Chemical for investigation some time ago. They are from Coal Head and have an air separation unit, including an air compressor and a nitrogen compressor. I would like to ask if there is an air separation device in Qitou Fertilizer? Is there a nitrogen press? If not, where does the nitrogen in the syngas come from?
There are nitrogen presses for liquid nitrogen cleaning and nitrogen-free presses for adding air to the second-stage furnace.
There is no air separation or nitrogen compressor in the gas head fertilizer plant. The gas head plant generally adopts the first and second stage conversion, high and low conversion, wet decarbonization, and methanation processes. The nitrogen produced by synthetic ammonia comes from the nitrogen in the air added by the second stage furnace.
Gas head fertilizers also have air separation and nitrogen compressors. The main uses of nitrogen include pipe replacement, catalyst protection during shutdown, and protective gas for ammonia tanks. In addition, some vent pipes are also nitrogen users. The nitrogen needed to prevent the accumulation of combustible gas in the process system is added by adding air to the second-stage furnace.
Thank you all experts. I have just come into contact with nitrogen fertilizers and I know some of the process departments very well.
