초록 ▼

A method to produce LNG at straddle plants. In contrast to known methods, there is provided a slipstream of a high pressure, pre-treated, pre-cooled natural gas stream to a straddle LNG plant section. The slipstream is further cooled, and processed in a high pressure column to a methane content of 85% or 85 plus by mole. The processed stream is further treated to remove carbon dioxide. The de-carbonated high pressure stream is further cooled in a heat exchanger by a counter-current vapor fraction of the expanded gas before entering an expander apparatus. The processed, treated and cooled gas is expanded into a separator. The produced LNG fraction is pumped to storage. A portion of the LNG fraction is used as a reflux stream to the high pressure column. The cold vapor fraction from the separator flows through counter-current heat exchangers, giving up its coolth energy before being re-compressed into the high pressure transmission gas pipeline.

1. A method to produce liquid natural gas (LNG) using an LNG plant feed stream, the LNG plant feed stream comprising a high pressure, pre-treated, pre-cooled natural gas stream from a straddle plant, the method comprising: cooling the LNG plant feed stream in at least one heat exchanger;removing natural gas liquids (NGLs) from the cooled LNG plant feed stream using a gas column downstream of the at least one heat exchanger;removing carbon dioxide gas from a vapor stream of the gas column using a gas treatment unit downstream of the gas column;cooling the vapor stream using one or more heat exchangers downstream of the gas treatment unit to produce a cooled de-carbonated stream;expanding the cooled de-carbonated stream in a gas expansion apparatus;providing an LNG separator downstream of the gas expansion apparatus to separate the expanded cooled de-carbonated stream into an LNG stream and a natural gas stream; andproviding a high pressure LNG pump for pumping a portion of the LNG stream to the gas column of the straddle plant as a reflux stream. 2. The method of claim 1, wherein the gas expansion apparatus is a JT valve or a gas expander turbine. 3. The method of claim 1, wherein cooling in one or more heat exchangers is provided by the natural gas stream from the LNG separator. 4. The method of claim 1, wherein the reflux stream to the gas column controls a methane concentration of an overhead stream of the gas column. 5. The method of claim 1, wherein the gas column produces a bottoms stream that is routed to the gas column as a gas column reflux and for NGL recovery. 6. The method of claim 1, wherein the gas treatment unit removes the carbon dioxide gas in an overhead stream of the gas column to a concentration of less than 50 ppm. 7. The method of claim 1, wherein the vapor stream downstream of the gas treatment unit is cooled by the natural gas stream from the LNG separator before entering the gas expansion apparatus. 8. The method of claim 2, wherein the gas column produces a bottoms stream that is a mixture of NGLs from the LNG plant feed stream, carbon dioxide and methane. 9. The method of claim 1, further comprising a straddle plant feed gas stream that feeds a distillation column, and wherein the LNG plant feed stream is obtained by diverting a portion of the straddle plant feed gas stream upstream of the distillation column. 10. The method of claim 9, wherein the NGLs from the gas column are expanded and injected into the distillation column as a distillation column reflux stream.
