I. Preface With the rapid development of industry, nitrogen has been widely used in chemical engineering, electronics, metallurgy, food, machinery an...
The pressure relief of molecular sieve in the purification system is generally rapid in the early stage, not complete and running overtime in the late...
When the same pressure is reduced, the temperature drop of throttling is far greater than that of expansion. This is because the gas does not work ext...
In the air separation plant, the adsorption capacity of the adsorbents is expressed by static adsorption capacity and dynamic adsorption capacity. The...
During the start-up phase, when the liquid volume accumulates in the condensing evaporator, the gas and liquid mixture will pass through the liquid ai...
A steel-making user of DEAR air separation set up their air separation plant in the early stage. At that time, due to the small amount of nitrogen req...
to increase oxygen extraction rate.The advantages and disadvantages of nitrogen expansion are:1) The gas does not enter the upper column after nitroge...
When the purity of the product decreases or the output decreases during the operation of the air separation plant, people will think of whether the he...
Before closing the throttle valve, the conditions for closing the valve should be created: the liquid oxygen liquid level is close to the normal liqui...
The flow integrator is used together with the flow meter and accumulates the total amount of fluid flowing through the pipeline within a certain perio...
In the internal compression process air separation plant, we generally select the the multistage centrifugal pump as the liquid nitrogen pump. In orde...
The liquid in the lower tower mainly comes from the liquid flowing from the first tower plate at the bottom. The liquid flowing down from the top Towe...
