Simultaneous contraction design for pressure pipes

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

DEAR air separation has provided several sets of air separation equipment for the metallurgical industry for many years, and has accumulated rich experience. The equipment is operated safely and stably, adopting the whole low pressure process of molecular sieve adsorption and turbine expansion machine refrigeration
