Dongxinyuan independently transformed the nitrogen production station to increase production and reduce costs

On November 24, Shaanxi Dongxinyuan Chemical Co.
, Ltd.
independently implemented the 281 nitrogen production station production and efficiency improvement technology transformation project - one new nitrogen generator was put into production and operation, the nitrogen production capacity increased from 4,000 standard square meters / hour to 6,000 standard square meters / hour, the nitrogen production capacity increased by 50%, greatly reduced the cost of liquid nitrogen purchase, and is expected to save more than 18 million yuan
per year.

Dongxinyuan Company Oil Branch Plant Purification and Desulfurization Workshop 281 Nitrogen Station original 2 nitrogen generators, during the operation of the nitrogen production device, nitrogen can not meet the production needs of the whole plant, need to purchase 40-50 tons
of liquid nitrogen every day.

In order to solve this problem, Dongxinyuan Company added a nitrogen generator, and adopted the patented technology of "a nitrogen station air compressor cooling system" to implement the transformation to improve the compressor efficiency, increase the nitrogen production capacity by about 2000 standard square meters / hour, and reduce the average daily replenishment of liquid nitrogen to 4-5 tons
.

It is reported that the 281 nitrogen production station of Dongxinyuan Company has a total of 7 air compressors, and the air compressor has been technically transformed to greatly reduce power consumption and improve gas production rate
.
In the later stage, the company will add a new air compressor to further improve the nitrogen production capacity, which can fully meet the nitrogen production needs of the whole plant and no longer purchase liquid nitrogen
.
At the same time, innovative technological transformation was implemented on the exhaust gas of nitrogen production stations to increase the hydrogen content
in the gas.
