CRYOSTAR’s first liquefaction units: Boil-off gas systems on LNG carriers Capacity ~7 tonnes per hour (turn down ratio ~30%), Following an extensive development program CRYOSTAR’s Ecorel process was selected for installation on the world’s largest LNG carriers Q-Max to the Qatar Gas Transport Company. The capacity of these vessels, 266’000 m3, exceeds by far all that of all other LNG vessels ever built More than 150,000 hours of combined operation (100 to 120 journeys) 2 x 14 units on Q-Max LNG carriers. In operation since 2008, 187 tpd 2 x 4 units to MOL for PNG LNG project, operational...

StarLiteLNG™ - small scale liquefaction system Based on its experience with the boil off gas re-liquefaction systems onboard LNG carriers, CRYOSTAR developed and now offers, through its StarLiteLNG™ family product, small scale LNG or LBG plants for onshore natural gas or biogas liquefaction applications with capacity from 20 to 200 tonnes per day (17 to 124 k GPD). CRYOSTAR focuses on a skid-mounted liquefaction unit. For additional packages such as gas treatment, polishing and balance of plant, we offer a solution in collaboration with customers and our network of partners. LNG block...

StarLiteLNG™ toolbox The idea of StarLiteLNG™ is to standardize and optimize a small scale LNG system from 20 to 200 tonnes per day (17 to 124 k GPD) based on a wide set of process variations. The toolbox is designed to cover about 90% of real-life boundary conditions, with the following major benefits: SAFE FINANCEABLE INNOVATIVE RELIABLE SAFE No flammable or toxic refrigerant storage for simpler regulatory compliance and less time to LNG production. A straightforward process control based on a single turbomachine (compander) in the refrigeration system. Automatic load control in a range...

StarLiteLNG™ compander machine A compander is a combined expander and compressor in a single, integrally-geared machine installed in the refrigerant cycle. CRYOSTAR built the first compander in 1996. Motor with medium voltage requirement « Coupling Guard Lube oil and seal gas system (25 to 45 Nm3/h of N2 consumption) « Compander with water cooling system for marine applications 3 compression and 1 expansion stages mounted on a common motor driven speed increasing gearbox. Expander power is recovered and reduces drive motor consumption. PREVENTATIVE MAINTENANCE 2 days per year and 14 days...

PEAK SHAVING SYSTEMS Truck loading station and equipment The peak shaving system allows natural gas to be stored and supplied on demand in case of increasing gas consumption, or gas supply outages from the natural gas grid. These systems usually require very high flows, as well as medium to high pressure. Once the LNG is pressurized, it is sent to the vaporizers before being injected into the grid. As part of our LNG systems portfolio, CRYOSTAR offers trailer unloading pumps, booster pumps, reciprocating high pressure pumps, as well as complete PLC controls solutions and cryogenic process...
