Large air separation unit heat exchanger head improvement
Large air separation unit heat exchanger head improvement
When the core body resistance is large, through the improvement of the head structure is actually very small, so when the height of the heat exchanger core body reaches a certain point, improve the structure of the head actually lost significance.
Products of Large air separation unit heat exchanger head improvement
The main applications of the air separation plant in petroleum industry include the use of natural gas or heavy oil to produce synthetic ammonia, olefin and petrochemical products, as well as providing nitrogen for oil extraction. The implementation of 1500 small air separation plant project cooperated with clients by DEAR air separation plant is beneficial to the improvement of crude oil processing scale in Shengli oilfiel
The industrial gases used in petrochemical industry include oxygen and nitrogen. The main applications include the use of natural gas or heavy oil to produce synthetic ammonia, olefin and petrochemical products, and providing nitrogen for oil extraction. Based on the principle of mutual benefit and win-win cooperation, DEAR Air Separation plant and the client jointly signed the small air separation plant 2000 project again
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...
