Heat recovery steam generation integration with high pressure feed gas processes for the production of liquefied natural gas

A method of producing liquefied natural gas (LNG), the method comprising:

• providing a natural gas stream at a pressure of less than 8.27 MPa (1,200 psia) from a supply of natural gas;
• compressing the natural gas stream to a pressure of at least 10.34 MPa (1,500 psia), wherein the compressing is performed using a first compressor and a second compressor;
• between the first compressor and the second compressor, cooling the natural gas stream so that the second compressor produces a cooled, compressed natural gas stream;
• liquefying the cooled, compressed natural gas stream in a liquefaction process, the liquefaction process using a refrigerant compressor configured to compress a stream of refrigerant used to chill, condense, or liquefy the cooled, compressed natural gas stream;
• using a heat recovery steam generation (HRSG) system, recovering heat from a power source of the refrigerant compressor and generating a stream of pressurized steam from the recovered heat;
• and
• powering at least one of the first and second compressors using at least part of the stream of pressurized steam.
