Pressure pipe support hangers of large air separation unit
Pressure pipe support hangers of large air separation unit
The brackets are directly related to the safety of the piping and liquid air separation plant in the cold box during operation at low temperatures. Deformation or even damage to the piping due to bracket problems is often found during maintenance.

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 stroke of the valve plate of the piston compressor valve of the small air separation unit should be reasonably selected according to the speed and pressure of the compressor and should not be too large or too small. If the valve stroke is too large, the valve blade may not open fully and may also close with a hysteresis due to the inertia of the moving parts. At the same time, if the stroke is too large, it will increase the speed of the valve blade when opening and closing, and the impact o...
Conventional liquid air separation plants are cooled by isothermal throttling refrigeration and expander refrigeration, LNG cold energy air separation eliminates the need for an expander and utilises the cooling capacity of LNG and isothermal throttling refrigeration. The air separation unit uses circulating nitrogen gas to liquefy into liquid nitrogen in a liquefier, which is fed into the lower tower, where the cold is transferred to the distillation system to pump the dirty liquid nitrogen thr...
