LPG Transfer

[hog roaster]

Is it possable to transfer LPG from a 47kg bottle to a LPG car?
If so what kit would you need?

Yes you naughty boy :naughty you need one of these http://www.ebay.co.uk/itm/LPG-autog...arts_Vehicles_CarParts_SM&hash=item43ae04f5f2
but this is a better bit of kit if you've the budget http://www.ebay.co.uk/itm/LPG-Pump-230V-/230747422414?pt=LH_DefaultDomain_3&hash=item35b99e3ece

I would love to know a cheaper way plank.

All you need is a high pressure hose and connectors, LPG is surprise surprise, liquid, liquid goes down hill, simply up end the bottle and put it higher than the receiving tank connector, yes it is that simple, apart from temperature, if the receiving tank is warmer then no transfer will take place if the bottle is warmer transfer can take place quite fast, but remember to maintain a gas space in the receiving tank, or no more car if it is in the sun after, has to have some place to expand to, Rick

So how does the air/gas get out of the tank in the car ? When we transfer we upturn the bottle but need to pressurise the car tank :nenau I had assumed the filling stopped when the pressure reached a set amount thus leaving the 20% spare space in it. I'm confused now

OK without getting too complicated, there is no "air" in the tank it is all "LPG" but it in two forms, gas (think of it a steam from boiling water) and liquid (think of it as water), the only way that your tank can maintain a gas space when filling is via a float valve or sensor that detects "liquid" level, and shuts off the supply, but this could be linked to the supply pump in normal circumstances, but filling from a 47 Kg is not "normal" so care needs to be taken, as for the transfer process, providing there is a small temperature difference at the start of the process, then liquid will flow down the line to the receiver, as it enters the receiver some will expand slightly causing a cooling effect, this keeps the receiver at a lower temperature than the giver tank so accelerating the process, given the right conditions a 47 Kg could drain in a matter of a few minutes, but more normally 30 or 40, or much more if temperature's are wrong, it is almost a part of the refrigeration cycle, Rick

Thanks Rick :thumbs I know there's a float in the tank as I had to mount the tank at the correct angle for it to work properly and gives a rough tank level indication. I love the theory and will try it out at next fill up :sly savings a gogo :naughty
