Stability of argon systems in small air separation units

Stability of argon systems in small air separation units
The high quality of the argon extraction rate of the air separation argon system mainly comes from the argon fraction of the upper tower, so the stability of the main tower working condition is the basis of the stability of the argon fraction, and the stability of the argon fraction is the basis of the stability of the operation of the crude argon tower.

1500/100 Y-type solution for small air separation plant in new material industry
The new material industry system of our country has been initially formed and the development situation is good. With the introduction of national strategic planning such as "The development plan of national strategic emerging industries in the 13th Five-Year Plan" and "The development plan of new material industry in the 13th Five-Year PlanThe new material industry system of DEAR air separation has been initially formed and the development situation is good. With the introduction of national strategic planning such as "The development plan of national strategic emerging industries in the 13th Five-Years Plan" and "The development plan of new material industry in the 13th Five-Years Plan", it has created a good policy environment for the development of new material industry. Recently, DEAR air separation cooperated with clients on the 1500/100 Y-type project of small air separation plant. The overall design of the project is reasonable, and the one-time drive is successful, and all the
4500/4500-type solution for small and medium-sized air separation plant in nonferrous industry
According to the influence and reform of the general environment of the non-ferrous industry, the problems faced by this industry are becoming more and more serious, and the control of production capacity is particularly important. Recently, the 4500/4500 type small air separation equipment project signed with customers by DEAR Air Separation, through the trial run stage, all the technical indicators have reached or exceeded the design standard, and have been continuously sending nitrogen for several days, which has been well received by users.

1. Before filling with pearlite, the water accumulated on the foundation surface of air separation unit must be removed, dried with hot air, and all manholes shall be closed. 2. When filling pearlite, all containers and pipes in the cold box should be inflated and kept at 50kPa pressure, then slightly open the valve of each meter pipeline, and all thermometers should be electrified to check whether the thermometer cable is damaged during the filling process. 3. The filled pearlite shall not be mixed with combustibles. 4. When filling with pearlite, coarse mesh or pearlite pouring device should be set at the manhole on the top of the cold box to prevent whole bag pearlite from entering the cold box. 5. After the pearlite is filled, the manhole shall be sealed.

When there is no pressure signal input, the valve is closed; when there is a pressure signal, the valve starts to open, and the larger the input signal, the larger the valve opening, this kind of film regulating valve is called air-opening film regulating valve in small air spearation unit. When there is no pressure signal input, the valve is fully open, and when there is a pressure signal input, the valve starts to close; the larger the input signal, the smaller the valve opening; when the inp...
