Application fields of cryogenic air separation equipment

In order to ensure the stable operation of the distillation column, the in and out material and its state of the distillation column needs to meet the material balance, component balance and energy balance. The main cooling liquid oxygen surface is an important indicator of whether the cooling capacity of the air separation plant is balanced or not. When the cooling loss of the unit is greater than the cooling capacity, the moisture content of the air entering and leaving the column (the liquid content in the saturated air) will be reduced, and the nitrogen to be condensate in main cooling needs to be condensed, the evaporation of liquid oxygen will also increase, and the surface of liquid oxygen will decrease. On the contrary, when the cooling capacity is greater than the cooling loss of the unit, the moisture content of the air entering the lower column will increase, and the amount of nitrogen to be condensed in the main cooling system will decrease, and the liquid oxygen surface wi

1. Enter the work area, wear all kinds of labor protection equipment; check the surrounding working environment; confirm the tools and machines; prohibit the use of defective tools. 2.When using the sledge hammer, it is forbidden to wear gloves; it is strictly forbidden to stand in the range of before, after, up, down, left and right of the sledge hammer, and no one is allowed to stand on the opposite side to prevent injury. 3.Before welding operation, it is necessary to carefully check whether the electric welding tools used are insulated, whether the primary and secondary wires of the welding machine are damaged, and whether the grounding wire is in good condition; insulating gloves must be worn to prevent the occurrence of electric shock accidents when the welding machine stops power transmission and switches on. 4.The safety protection facilities of oxygen cylinder and acetylene cylinder should be complete and reliable. When working, the distance between oxygen cylinder an
