Dear penney,
Thanks a lot for quick responce. . .
Dear Ravi,
Please let us know. . .Again does you have any specific questions please come forward. . .

dear ravi,
both the operations cannot be performed at the same time.
you need to pressurize the tanker for the liquid drawal. if that is the case, how it would be possible for both. are you using nitrogen for pressurizing the tank or the LPG - gas itself?
kindly provide the details of your unloading pump & the unloading line details, so that I can give some updates.
dear penny,
you have provided one useful link. but sorry, this will not answer ravi's question..

Dear ravi,
we are using compressor for the same purpose.Depending on the pressure difference between LPG bullet & LPG tanker commpressor is used.Firstly liquid is taken out & than vapour is unlaoded.
If pressure in tanker is more than it comes out automatically & if pressure is low than we use commpressor for transfer of LPG from tanker to bullet.We also have Bullets above ground level.
Grounding & bonding are taken care of. we have QBDs for detections.& sprinkler systems both in auto & manual.
Regards,
Hansa
