Open the CIPO recordAbstract From the Canadian patent
A system takes low pressure (LP) liquid and transfers them into a high pressure (HP) gas pipeline using an energy transfer system. A volume of HP gas is used as the energy source for driving a lesser volume of LP liquid into, a HP downstream system. Preferably liquids separated from wellhead effluent are separated from gases and are directed to the energy transfer pump for transfer into a HP gas pipeline. Substantially dry gases from the HP pipeline are, directed to the energy transfer pump for providing the drive energy for elevating, the pressure of the liquids. This system eliminates the prior art blowcase vessel, system and does not require onsite utilities.
