Maintenance of air compressor

Maintenance of air compressor
Air compressor as an indispensable part of air separation equipment, once abnormal will have a great impact on production, so the maintenance of air compressor must be paid enough attention by enterprises. The maintenance of air compressor is as important as the maintenance of other equipment of air separation plant. If the maintenance can be done in place, the failure rate of air separation equipment will be reduced. The unit responsible for the maintenance of air compressor needs manufacturers with high professional level, timely and efficient service and high-quality accessories. For details, please leave a message or call us for consultation. DEAR air separation is looking forward to cooperating with you.

The expansion air volume entering the upper tower increases, and the reflux ratio of the distillation section decreases correspondingly. In order to achieve the required purity of nitrogen products, more tower plates need to be set. When the reflux ratio is reduced to countless Tower plates needed to be set to make the purity of nitrogen reach the required value, then the reflux ratio is called the minimum reflux ratio. The expansion air volume entering the upper tower is first limited by the minimum reflux ratio. The closer the reflux ratio is to the minimum reflux ratio, the faster the number of tower plates needed to ensure the product purity increases, which will lead to the increase of investment, the increase of tower plate resistance, the increase of Operation pressure and the increase of energy consumption. Therefore, the reflux ratio after the inflated air enters the tower should be larger than the minimum reflux ratio. When the purity of nitrogen is required to be low, the...

Internal compression air separation process is a process form in which liquid products are pressurized by liquid pump in the cold box, and then sent out of the cold box after reheating by high-pressure heat exchanger. The working pressure of internal compression process generally exceeds the critical point of oxygen and nitrogen. Heat transfer of liquid in supercritical state is a major feature of internal compression process. In the distillation process, due to the difference of product types and acquisition methods, there is a big difference between the material import and export of internal equipment and external compression process. In the internal compressed air separation process, the pressure of oxygen is not limited, the maximum output of nitrogen can reach 2.8 times of that of oxygen, and the extraction rate of argon can reach about 85%. The internal compression air separation process is generally composed of internal compression system, air precooling system, molecular sie
