ABSTRACT:
A sub-sea submersible compressing apparatus having at least one compressor tank. A compressor tank is configured to receive gas from a gas/liquid separator and has an inlet for water. The compressor further comprises a pump to pump water from the compressor tank thereby drawing gas into the compressor tank from the gas/liquid separator. Valves are provided to shut off gas flow from the liquid/gas separator and to permit gas flow from the compressor tank to a predetermined location such as a recovery line for transferring the gas to the surface or other location. The gas contained within the compressor tank is compressed by allowing water to flow back into the compressor tank, thereby compressing the gas and forcing it from the compressor vessel. Two or more compressor tanks can be provided to facilitate a continuous operation by timing of the water flow to and from each of the compressor tanks.
