Content

Open the purge valve and the tank truck pipeline vent valve, and purge the unloading truck hose with nitrogen respectively.

After the purge is completed, close the nitrogen purge valve and slowly open the liquid phase pipe valve of the unloading truck supercharger to pre-cool the pipeline (frost on the supercharger inlet flange is regarded as pre-cooling completion, which takes about 10 minutes). Afterwards, the supercharger pipeline valve was fully opened to pressurize the tanker to 0.7 MPa.
