ABSTRACT:
A gas delivery apparatus which includes a vehicle fitted with multiple compressed gas cylinders, each provided with a free piston, along with a separate liquid reservoir cylinder, for sequentially displacing the gas located on one side of the free piston in each of the gas cylinders with liquid from the reservoir introduced on the opposite side of the free piston and relocating the free piston disposed in each gas cylinder by residual gas pressure. A method for dispensing compressed gas such as compressed natural gas from gas-filled cylinders containing a free piston and fitted with piping for introducing a liquid into each cylinder on one side of the piston to dispense gas from the opposite side of the piston, which method includes the steps of loading the cylinders with compressed gas, transporting the cylinders to a receiving reservoir location, attaching the gas side of the piston to the receiving reservoir, introducing water into the cylinder on the opposite side of the piston and forcing the piston through the cylinder to flow the gas from the cylinder into the reservoir.
