Case of DEAR air separation and Jiujiang Branch of Sinopec
Jiujiang Branch of Sinopec
Jiujiang Branch of Sinopec (hereinafter referred to as Jiujiang Petrochemical) is located at the foot of Lu Mountain, the bank of the Changjiang River and Poyang Lake. Formerly known as Jiujiang refinery, was approved by the state in 1975 and put into operation in October 1980. It is an enterprise directly under Sinopec, a key enterprise in central China and along the Changjiang River Basin, and the only large-scale petrochemical enterprise in Jiangxi Province.

Project Overview

KDN-2000 air separation plant signed by DEAR air separation and Jiujiang Petrochemical Co., Ltd has the process characteristics: single-stage distillation and high-purity nitrogen.

Product Advantage

The unit adopts molecular sieve purification, booster turbine expander to supply the cooling capacity of the unit. At the same time, it adopts nitrogen production process with double towers and double condensations. The extraction rate of nitrogen was about 70%.

1.Good safety

The whole set of device has the advantages of low operating pressure, simple process, high equipment safety, long switching cycle of molecular sieve system, increased service life of switching valve, and reduced potential hazards.

 

2.High reliability

Water chillers are used to reduce the failure of moving equipment.

 

3.Convenient operation and maintenanceandsimple process
