  • Patent number: 6056004
    Abstract: A portable compression system for pipeline purging having a first stage comprising a power turbine which drives an air intake compressor. An air cooler is connected to a recovery plenum line from the power turbine. A drive shaft extending from the power turbine operates a compressor that is connected to the air cooler. An exhaust line is connected to the compressor, so that exhaust gas produced by the power turbine is utilized as a compressed gas. Second and third stages are provided having a plurality of air coolers between compressors that are connected to the first stage, so that the final compressed gas can be utilized for purging pipelines.

  • Patent number: 6014995
    Abstract: An onsite petrochemical storage and transport system comprising a land based facility, which provides storage at a well site for hydrocarbon reservoir products which include gas, oil and water at a high pressure. The pressurized mixture is transferred, by means of pressure equalization, into a truck with multiple pressure containing vessels and transported to a plant suitable for processing the raw hydrocarbon mixture. The well site facility and transport truck are configured to allow for separation of gas and liquids to selectively transfer the gas or liquids as desired. Remote well sites may be periodically serviced by transport trucks while maintaining continuous production.
