On August 20, the newly added pipeline of Zhenhai Refinery and Chemical Gas-phase Ethylene Direct Supply to Ningbo Juhua Technology Co.
, Ltd.
was successfully put into use, and the current throughput is 1.
5 tons per hour
.
Previously, some ethylene products of Zhenhai Refinery were sent to surrounding enterprises by storage and transportation of low-temperature tanks.
Ethylene products were stored in the low-temperature tank area after being cryogenically cooled in a cold box, and then heated to room temperature by a vaporizer for delivery, consuming binary refrigerants.
Increase the load on the binary refrigeration compressor
.
The ethylene line is about 1200 meters long to the meeting point of Ningbo Juhua and SK companies respectively, and the whole process pipeline is 12 kilometers long
.
After the direct delivery is realized, the load of the binary refrigeration compressor of the ethylene unit will decrease, not only the consumption of high-pressure steam will be significantly reduced, but also the space for increasing the load of the ethylene unit will increase, and the consumption of low-temperature ethylene vaporization steam will be reduced accordingly.
A total of 2.
56 million yuan
.
