摘要： A method of separating acid gases, particularly carbon dioxide, from methane by cryogenic distillation. The method includes the step of adding helium to the stream to be separated to increase the critical pressure of the methane-carbon dioxide present. The cryogenic distillation tower may then be operated at a higher pressure and without the formation of solid carbon dioxide.

摘要： Methods and systems for treating a compressed gas stream. The compressed gas stream is cooled and liquids are removed therefrom to form a dry gas stream, which is chilled in a first heat exchanger. Liquids are separated therefrom, thereby producing a cold vapor stream and a liquids stream. A first part of the cold vapor stream is expanded to produce a cold two-phase fluid stream, and a second part of the cold vapor stream is cooled to form a cooled reflux stream. Various streams are fed into a separation column to produce a cold fuel gas stream and a low temperature liquids stream. The second part of the cold vapor stream is cooled by the cold fuel gas stream, which becomes a warmed fuel gas stream that is compressed and used with the low-temperature liquids stream to chill the dry gas stream and to cool the compressed gas stream.

摘要： A process for converting a gaseous hydrocarbon feed comprising methane to an aromatic hydrocarbon is integrated with liquefied natural gas (LNG) and/or pipeline gas production. The gaseous hydrocarbon feed is supplied to a conversion zone comprising at least one dehydroaromatization catalyst and is contacted with the catalyst under conversion conditions to produce a gaseous effluent stream comprising at least one aromatic compound, unreacted methane and H2. The gaseous effluent stream is then separated into a first product stream comprising said at least one aromatic compound and a second product stream comprising unreacted methane and H2. The second product stream is further separated into a methane-rich stream and a hydrogen-rich stream and at least part of the methane-rich stream is passed to LNG and/or pipeline gas production.

摘要： Methods and systems for recovery of natural gas liquids (NGL) and a pressurized methane-rich sales gas from liquefied natural gas (LNG) are disclosed. In certain embodiments, LNG passes through a heat exchanger, thereby heating and vaporizing at least a portion of the LNG. The partially vaporized LNG passes to a fractionation column where a liquid stream enriched with ethane plus and a methane-rich vapor stream are withdrawn. The withdrawn methane-rich vapor stream passes through the heat exchanger to condense the vapor and produce a two phase stream, which is separated in a separator into at least a methane-rich liquid portion and a methane-rich gas portion. A pump pressurizes the methane-rich liquid portion prior to vaporization and delivery to a pipeline. The methane-rich gas portion may be compressed and combined with the vaporized methane-rich liquid portion or used as plant site fuel.

摘要： A process for converting a gaseous hydrocarbon feed comprising methane to an aromatic hydrocarbon is integrated with liquefied natural gas (LNG) and/or pipeline gas production. In the integrated process, the gaseous hydrocarbon feed is supplied to a conversion zone comprising at least one dehydroaromatization catalyst and is contacted with the catalyst under conversion conditions to produce a gaseous effluent stream comprising at least one aromatic compound, unreacted methane and H2. The gaseous effluent stream is then separated into a first product stream comprising said at least one aromatic compound and a second product stream comprising unreacted methane and H2. The second product stream is further separated into a methane-rich stream and a hydrogen-rich stream and at least part of the methane-rich stream is passed to LNG and/or pipeline gas production. The gaseous hydrocarbon feed supplied to the conversion zone has at least one of the following properties: (i) a sulfur level of at least 25 ppm by volume; (ii) a CO2 level of at least 50 ppm by volume; and (iii) a dew point of at least 203° K.

摘要： Methods and systems for dynamically planning a well site are provided herein. Methods include flowing a raw gas stream though a suction scrubber to form a feed gas stream and compressing the feed gas stream to form a compressed gas stream. Methods include cooling the compressed gas stream in a cooler to produce a cooled gas stream. Methods include feeding the cooled gas stream into a gas treatment system, using a turboexpander, to produce a conditioned gas and a waste stream. Methods include heating the conditioned gas in a heat exchanger, where the conditioned gas is a superheated, sweetened, gas. Methods also include burning the conditioned gas in a turbine generator and mixing the waste stream into the raw gas stream upstream of the suction scrubber.
