Open the valve on the pipeline and open the feed valve at the bottom of the tank.
A few days ago, the D-7301 spherical tank of the storage and transportation workshop of the Shanghai Petrochemical Department of Fine Chemicals began to receive C5 device dicyclopentadiene products.
This marks the successful completion of the VOCs emission rectification project of the Shuanghuan product atmospheric vaulted tank breathing valve and its official commissioning.
It also means that two atmospheric vault tanks that have been in operation for 26 years and two atmospheric vault tanks that have been in operation for 19 years will end their mission.
, Enter the deactivation period.
Shuanghuan product tanks were originally mixed pressure tanks and atmospheric dome tanks.
After the rectification of this project, all pressure tanks will be adopted to avoid bulging of dome tanks due to series pressure between tanks or dome tanks caused by excessive discharge time.
Safety accidents such as deflation have improved the safety of the collection and discharge operations.
At the same time, all pressure tanks can be used to prevent VOCs from being discharged when the vault tank breathing valve exhales, which will effectively improve the quality of the surrounding environment, which can be described as killing two birds with one stone.
