The distillation tower can operate stably only when all the materials entering and leaving the distillation tower and their states meet the material balance, component balance and energy balance. The main cooling liquid oxygen surface is an important sign of whether the refrigerating capacity of the air separation unit is balanced between the generation and consumption. When the cooling loss of the unit is greater than the refrigerating capacity, the moisture content of the air entering the lower tower will be reduced, and the amount of nitrogen that needs to be condensed in the main cooling will increase. Of course, the evaporation of liquid oxygen will also increase, and the liquid oxygen surface will decrease. On the contrary, when the refrigerating capacity is greater than the cooling loss of the device, the moisture content of the air entering the lower tower will increase, the amount of nitrogen that needs to be condensed in the main cooling will decrease, and the liquid oxygen level will increase.
The kdon-300/3000 air separation equipment supplied by Kaifeng DEAR air separation to Shandong Kenli Petrochemical Company is a patented product independently developed by Kaifeng Deere air separation industry Co., Ltd. with excellent performance and exquisite workmanship. In the design and production of this kdon-300/3000 high-purity nitrogen hanging oxygen tower and the manufacturing equipment of energy-saving and environmental friendly industrial gas, Kaifeng Deere air separation keeps improving and has obtained a number of scientific and technological achievements and practical patents, It effectively solves the problem that the pre separated air enters the upper tower slowly and incompletely due to the small pressure difference between the upper tower and the lower tower. It has been highly recognized by Kenli petrochemical.
