4000/4000-900 solution for complete air separation plant in fertilizer industry
In the fertilizer industry, the air separation plant is mainly used for the production of nitrogenous fertilizer, accounting for 65-70% of the fertilizer structure in our country. The main raw material of chemical fertilizer is synthetic ammonia. The production and development direction of synthetic ammonia in our country mainly takes coal as raw material, adopts new coal gasification technology to build large-scale synthetic ammonia production enterprises, and eliminates small enterprises with high energy consumption and high pollution. In the production of synthetic ammonia

The liquid air separation plant uses circulating nitrogen to absorb the cold end of LNG, thus replacing the traditional hot and cold end expanders of the liquid air separation plant. The liquid air separation plant energy consumption is reduced by using glycol aqueous solution closed circuit to absorb the cold at the high temperature end of LNG, thus replacing the traditional cool water tower with lower cooling water temperature and less water consumption. The key of the liquid air separation pl...

A decrease in atmospheric pressure will increase the compression ratio of the air compressor. A decrease in atmospheric pressure will increase the compression ratio of the air compressor by 6-8% and increase the energy consumption for compression. In addition, due to the increased mass to volume ratio (reduced density), the exhaust volume of the air compressor will be reduced and the relative oxygen production will be reduced, increasing the unit electricity consumption of oxygen production. Th...
