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

The following precautions should be taken in the operation of a pressurised expander:
do not allow the interlock to be removed to start the expander under any circumstances.
control the inlet temperature of the expander to be no lower than -118°C.
It is not permitted to start the expander with the booster bypass valve FCV401 closed, and the expander should be pre-cooled befor...
What are the requirements for the design of piping in the cold box of liquid air separation plant?
The design of piping in the cold box ofiquid air separation plant is complex and troublesome, and each pipeline has its own process requirements. As one of the most complex components in the cold box of air separation equipment, low temperature piping is the key to ensure the stable and safe operation of small air separation unit. A set of air separation equipment in the cold / hot end of the plat...
