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
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...
In order to avoid microbial resistance to a single agent, weakening the effect of dosing, the use of two kinds of algaecide in the water circulation system of small air separation unit alternately added. When adding algaecide, first clean the cooling tower tower pool, then add algaecide and maintain 6 to 8 hours without drainage.
As the open circulating cooling water and outside contact with a wide range, most likely to breed algae and biological slime. In order to achieve the best effect of ba...
