Processing errors resulting in different fin channel sizes have a greater impact on the distribution of the flow. Uneven flow paths, which cause partial flow of fluid, and thus affect the overall performance of the heat exchanger.
Products of Quality of fins for small air separation unit
In other fields of chemical industry, the demand for air separation plant is stable. In response to the production demand of customers, both parties cooperate on the 2000/3600 type project of small air separation plant, it can solve the problems of customer's raw material pretreatment, delayed coking unit and comprehensive utilization.
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
If the air temperature in the small air separation unit expander is lower than the liquefaction temperature corresponding to the local pressure, part of the gas will liquefy and droplets will appear in the expander. However, the rotating speed of the working wheel of the turbo expander is very high, and the droplet impact on the impeller will cause the impeller surface wear. The droplets may also be thrown to the gap ...
