Core tips: the safety that should be paid attention to when touching nitrogen: nitrogen is colorless, odorless and odorless lazy gas. It itself does no harm to human body. If people absorb pure nitrogen, they will be suffocated due to severe anoxia and thus die.

Test process of stainless steel pipe section of air separation unit

1. When working at a height of more than 2 meters or multilevel cross operation, special personnel shall be assigned to guard or contact with each other, and it is strictly forbidden to command by more than one person. 2. The safety belt must be worn when working at a height of more than 2 meters, and it should be hung high and low. It is forbidden to hang the safety belt on the maintenance objects, on the pipelines and equipment (including electrical) of various dangerous media, and it is forbidden to drag the safety belt on the ground. It is strictly forbidden to use nylon material safety belt in high-temperature area or welding operation, and the flame-retardant and high-temperature resistant safety belt should be selected. 3. If there are high falling objects, the articles should be cleaned up in time, or the falling prevention measures should be added. 4. The safety rope should be lowered from the top of the silo as the hanging point of the safety belt for the high-altitu

What is the effect of increasing the amount of processing air on the distillation conditions and what corresponding measures need to be taken

First of all, it completely conforms to the general principle of distillation organization and simplifies the organization of air separation distillation. Secondly, after the air separation distillation is organized in this way, the argon component in the air is almost completely in the oxygen argon mixture at the bottom of the air separation column, which is greatly conducive to the improvement of nitrogen ...

How to store liquid products in air separation equipment?

Air compressor intermediate cooler is generally shell-tube structure. Water is supplied inside the pipe, and gas is supplied between the pipes, which plays a cooling role through the heat exchange of fluid inside and outside the pipe. The reasons that affect the cooling effect of compressor intermediate cooler include: 1) insufficient cooling water. The heat of the air is not enough to be taken away by the cooling water, resulting in the increase of the next level of suction temperature, the decrease of gas density, and finally the reduction of exhaust volume. Therefore, the water supply pressure of cooling water should be closely monitored during operation to control the water supply. The process generally requires that the cooling water pressure should be greater than 0.15MPa (surface pressure); 2) the cooling water temperature is too high. High water temperature reduces the temperature difference between water and gas, and reduces the effect of heat and cooling. Even if the amoun...
