Decanting Method of Gas Bottle Refill - How to Fill a Gas Bottle
Gas bottle refillo by decanting LPGDecanting is the process seen if you have ever watched a gas bottle refill at a service station. After connecting the gas bottle to a larger LPG storage tank, the trained operator begins the LPG refill until some gas starts leaking out of the loosened bleed screw.
The operator is supposed to stop the LPG refill as soon as liquid LPG starts coming out of the bleeder opening.
The liquid LPG escaping is unmistakable, as it looks like a white cloud.
This intentional venting of gas into the atmosphere is avoided with the digital scale method.
Decanting can also result in either overfilling or under filling, as well as correct LPG refill, depending on the gas bottle and the operator filling it.
For example, if the operator is slow to stop the gas bottle refill when the liquid LPG starts to bleed out, the gas bottle could easily become overfilled.
As previously mentioned, overfilling is a significant safety hazard.

When disconnecting the hose from the customer cylinder, shouldn’t the valve on the main cylinder also be shut? Otherwise I can’t release any residual gas in the hose because it will just continue flowing? Or am I missing something

The recap towards the end of the video explains that you should turn off the customer valve and the supply valve before releasing residual gas
