Specification for the design of piping for small air separation unit
A small air separation plant has more than 150 pipelines inside the cold box. Most of the piping has been verified, calculated and combined with the design experience inside to form a detailed design specification.
Products of Specification for the design of piping for small air separation unit
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
Air separation unit not only has the distillation and separation process of air under the condition of deep cooling, but also the process of keeping the air separation unit in the deep cold state and making the cryogenic liquid products. Therefore, in addition to distillation process, air separation unit has a very important refrigeration process.
Unlike the general refrigeration process of heat pump, the refrigeration prin...
The liquid oxygen from the main condensing evaporator is compressed by the internal compressed oxygen pump, evaporated and reheated into the main heat exchanger and then out of the cold box as oxygen product. The low-pressure nitrogen is pumped out from the top of the low-pressure tower, and its cooling capacity is transferred to the reflux liquid in the subcooler, which is sent out of the cold box through the main heat exchanger, partially compressed by the first stage of the nitrogen make-up c...
