Burckhardt Compression has received an order for three Laby® compressors to be delivered to Gijon, Spain, for the LNG receiving terminal at the port of El Musel.
Burckhardt Compression recorded an order from Enagás to deliver three Laby (labyrinth piston) compressors for the liquid natural gas (LNG) receiving terminal that is part of the new regasification plant in El Musel.
The Laby has a unique ultra-low maintenance piston sealing design and is therefore the ideal solution for low-temperature boil-off gas applications. The gastight design reduces gas emission and losses to the environment to zero. For any LNG boil-off gas applications the Laby is the compressor to be used, since it designed to reliably and efficiently manage these specific requirements.
Delivery of the three compressors will take place mid-2010. Burckhardt Compression has already delivered several Laby compressors for a similar LNG storage and distribution plant in Barcelona, which is also operated by Enagás.
The new installation will have an initial storage capacity of 300,000m³ of LNG. This will be split between two storage tanks, with 150,000m³ of LNG each, with a total emission capacity of 800,000m³ natural gas per hour. The docking terminal is specifically designed for gas tankers carrying LNG loads of up to 260,000m³. Two more storage tanks, that will take the final emission capacity up to 1,200,000m³ of natural gas per hour, will be built at a later date.
Laby compressors are used for liquid gas transport and storage as well as in the chemical and petrochemical industries. Laby compressors compress bone-dry, dirty, abrasive and other gases with no contamination and without oil, with a discharge pressure up to 300bar (4,350psi), flow up to 11,000Nm³/h (6,500scfm) and shaft power up to 2,200 kW (3,000 HP).
Laby compressors are extremely reliable machines with unexcelled availability, combining high performance with a unique cooling system. Burckhardt Compression’s Laby easily manages the compression of LNG boil-off gas at suction temperatures down to -170°C (-250F). The compressors will be used to re-liquefy boil-off gas that forms during LNG unloading of the LNG carriers and to maintain the LNG storage temperature at -170°C.
