Industry, it is a key equipment in gas, chemical, energy and other industries.
Note: During the process of unloading, the compressor pressurizes the gas from the storage tank and then presses it into the tanker through the gas phase pipeline. The pressure difference in the gas phase presses the liquid from the tanker to the storage tank to complete the process.
The process of unloading the truck. When the gas phase is pressurized, the gas phase temperature will increase. At this time, there is no need for forced cooling, because if the gas phase is compressed and then cooled, it will easily liquefy.
It is difficult to establish the gas phase pressure difference, which is not conducive to the replacement of the gas phase and the liquid phase. In short, it will cause the unloading process to be prolonged. If residual gas recovery is required, perform the residual gas recovery operation
In this case, a cooler can be selected to force-cool the gas phase so that the remaining gas can be recovered as quickly as possible.
The loading process is opposite to the unloading process
