Shenger air separation equipment the impact of liquid nitrogen withdrawal amount on purity. 

During the operation of the air separation equipment, the amount of nitrogen from the lower tower liquid has a significant impact on the purity of the final product. If the amount of removal of the lower tower liquid nitrogen may cause the increase in impurities in the liquid nitrogen, thereby reducing the purity of the final oxygen or nitrogen. This is because excessive liquid nitrogen removal will disturb the distillation balance in the separation tower, so that the unprecedented air components that are not fully separated are mixed into pure liquid nitrogen. Excessive extraction volume may also cause the internal pressure and temperature of the equipment to further affect the separation effect. In actual operation, the amount of nitrogen from tower liquid must be strictly controlled to ensure the stable operation of the equipment and the high purity of the product. By accurate monitoring and adjustment, the amount of liquid nitrogen can be optimized, thereby improving the efficiency and product quality of air separation equipment. This process requires technical personnel to have rich operating experience and professional knowledge in order to make correct adjustments and judgments under different operating conditions.
