Lng train debottlenecking - the technology success procede D'elimination des goulots D'etranglement dans la production de gaz naturel liquefie -le succes technologique

摘要

The North West Shelf Gas Project (NWSGP) has successfully carried out a 3 Train LNG plant debottlenecking to increase capacity from 6.9 to mroe than 7.5 million tonnes per annum. The two major constraints targeted by the project were the CO2 removal column and the main refrigerant compressor drivers. Replacement of the original trays by structured packing in the Sulfinol absorber columns and a change of solvent composition has cured foaming problems and increased gas-treating capacity. The installation of advanced technology parts (ATP) has effectively uprated the gas turbine drivers of the refrigerant compressors from GE Frame 5B to 5C. An increase in turbine power of 9
