Siemens had been initially awarded a contract to supply the first 10 compressor trains for the Magnolia LNG project at the Port of Lake Charles, Louisiana. The mid-scale project, with a capacity of 8 million tons per annum (mtpa), is developed by Australia-listed LNG Ltd.
Siemens' initial scope of supply comprised a total of eight refrigeration compressors and two feed gas booster compressors for the initial two liquefaction trains. Four mixed refrigerant (MR) Siemens STC-SV compressors will each be driven by a Siemens SGT-750 gas turbine, while four ammonia refrigerant (AR) STC-SV compressors will each be driven by a Siemens SST-600 steam turbine. Additionally, two motor driven feed gas booster compressors will be delivered.
The subsequent two LNG trains necessary to achieve the full 8 mtpa capacity for Magnolia will bring the total number of compressor trains to 20 at this site.
Eager to venture into the LNG market, Siemens has set up a supplier alliance agreement for process compression equipment and drivers. The company’s strategy is to standardize the implementation of the optimized single mixed refrigerant (OSMR) liquefaction technology worldwide.
