Problems solved by technology

Not only lost production time, but also let off a large amount of qualified hydrogen and nitrogen
It causes a serious waste of energy resources, and also leads to low production of synthetic ammonia, high gas consumption and high power consumption for a long time

Embodiment Construction

[0018] In terms of operation, the "three or four through" is used intermittently. The operation methods and procedures of the first, second and third stages stipulated in the normal start-up and start-up operation procedures after overhaul are unchanged, but at this time close the three-four straight-through valves, slightly open the four-inlet large valves, and directly pass the qualified N 2 、H 2 (Methanation) Introduce the inlet of the fourth stage of the compressor, control the inlet pressure within the range of 0.1-0.25MPa, and then enter the fifth and sixth stages in turn. This avoids CO, CO 2 With qualified H 2 N 2 The gas enters the ammonia synthesis. When the whole plant was shut down for inspection and original start-up, because the process after the fourth stage was not started, there was no gas in the inlet main pipe, only the first, second, and third stages had gas, and the normal and safe operation of the machine must be ensured. At this time, the three-four ...

Abstract

This invention discloses improved M type compressor operational method. It reduces the working procedures after harmful gas CO2 and CO entering into three sections of compressor. It reduces gas dissipation and current drain of synthetic ammonia production. It increases the yield. This invention is adequate for operations improvements of intermittent synthetic ammonia production compressor.

Description

technical field [0001] The invention belongs to the improvement of the operation method of the M-type compressor, which is suitable for the compression section of intermittent synthetic ammonia production and optimizes the operation of the compressor. Background technique [0002] The compression section of synthetic ammonia production, its main task is to transport various media to each process (transformation, decarbonization, carbonization, methanation, synthesis, etc.), and provide the necessary pressure conditions for the production process. Therefore, this section occupies an extremely important position in the entire synthetic ammonia production process and belongs to the heart position. The production capacity of the compressor and its performance are the key factors that directly determine the production of synthetic ammonia. Whether the operation is optimized directly affects the production consumption. The power consumption of synthetic ammonia is mainly concentr...
