The StarLNG™ family

The StarLNG™ concept was originally developed for the typical small scale capacity range of 100 to 600 tonnes per day (tpd) and was based on Linde’s proprietary single mixed refrigerant liquefaction process LIMUM®1 using plate-fin heat exchangers (PFHE). During concept development, the engineers recognised that many of the standardised design solutions and features can also be applied to LNG plants using other liquefaction technologies. Therefore the concept was extended to larger-scale plants up to 1 million tonnes per year (mtpa) using the LIMUM®3 process based on Linde’s proprietary coil-wound heat exchangers (CWHE). Recently the StarLNG™ family was completed by adding plant concepts using packaged proprietary nitrogen expanderbased liquefaction processes, either for small-scale, highly modularised standalone LNG units or for integration into existing or new NGL extraction facilities.
The following figure gives an overview of the different members of the StarLNG™ family together with the applied liquefaction processes, refrigerants, compressor types and main cryogenic heat exchangers.
On the following pages, the various StarLNG™ family members are described in more detail.
Benefits of the StarLNG™ product family
 Safe, simple, robust and highly efficient process design
• Strong focus on health and safety makes our small- to mid-scale LNG plants as safe as our world-scale plants
• Process design validated in dynamic simulations
• High reliability, robust design and ease of operation due to high degree of automation; remote control possible
Fast-track EPC time schedule
• Pre-engineered toolkit for process and plant design, standard documentation and modularised plant layout for shortest delivery time with minimum on-site construction effort
Lowest CAPEX
• Toolkit approach supports customisation, while benefiting from standardisation and production cost efficiencies of best-cost countries StarLNG™ – a versatile toolkit
