StarLNGL™

With a patent pending, Linde Process Plants is in a unique position to integrate a new LNG plant into existing NGL plants. The StarLNGL™ unit is an addition to the StarLNG™ family, providing more flexibility in the constantly changing natural gas and liquids market.

StarLNGL™, the integrated Liquefied Natural Gas (LNG) and Natural Gas Liquids (NGL) technology, uses proven design concepts to enhance LNG production in existing and new NGL recovery plants. As part of the StarLNG™ family, StarLNGL™ builds on Linde’s worldwide experience across the entire LNG value chain.
StarLNGL™ can be used with a variety of NGL recovery technologies including CRYO-PLUS™, GSP and RSV. Compared with a stand-alone LNG plant, the integrated StarLNGL™ solution provides the following benefits:

  • No impact on availability or reliability of the NGL recovery plant

  • Same or higher levels of ethane and propane recovery

  • Increased NGL plant capacity

  • Less capital expenditure

  • Highly efficient process

  • Shared maintenance

  • Lower operating cost

This concept utilises the heat integration of the NGL plant by taking a portion of the cold vapour stream from the recovery column, thus improving the efficiency of the LNG and NGL units.
 Technology highlights include:

  • Cold vapour feed to the StarLNGL™ unit

  • Minimum tie-ins to existing NGL unit required 

  • On-spec LNG ethane and propane recovery

  • Standard refrigeration technology

  • Refrigeration options include no hydrocarbon storage

  • Compact rotating equipment design

 Additional StarLNGL™ delivery options include:

  • Integrated solution combining plate-fin heat exchangers

  • Integrated solution utilising existing NGL plant compression
