fuel gas and liquefied natural gas production at the same time as liquefied natural gas production units

摘要

The present invention is heated after the separation of liquefied petroleum gas in the pretreatment of natural gas by integrating the pre-cooling unit of the pre-heating unit and the liquefied natural gas production unit for supplying fuel gas to the fuel gas supply device supplies from wells as a unit fuel at the same time with supplying the gas supply, the liquefied petroleum gas is separated natural gas is cooled by liquefied natural gas produced by the liquefied natural fuel gas supply can be supplied to the gas storage and liquefied natural gas production available liquefied natural same time gas production equipment It relates. ; The fuel gas supply and the liquefied natural gas production is available liquefied natural gas producing apparatus, the pre-processing natural supplied from gas wells the gas is a fuel gas pre-heater by separating the LPG generated while passed through a natural gas pre-cooling through a liquefied petroleum gas separator at the same time being the refrigerant and the heat exchange room temperature high pressure supplied to the fuel gas pre-heater from the refrigerant condenser to supply a liquefied petroleum gas is heated by the fuel gas is supplied to the fuel gas supply device, the refrigerant is cooled by recovering the cold energy from a low temperature of the liquefied petroleum gas by so that can it be to remove the liquefied petroleum gas in the pretreatment of natural gas as a unit to produce liquefied natural gas at the same time with supplying the fuel gas supply device to simplify the whole apparatus to reduce the equipment cost, the fuel gas supply to greatly improve the production efficiency as well as does not supply the refrigerant separately used for the pre-cooling unit of the pre-heating can be reduced the heat source may reduce the running cost of the apparatus, the liquefied natural gas production unit for supplying a fuel gas number is effective to make. ; Natural gas, liquefied petroleum gas, liquefied natural gas, liquefied petroleum gas separator, the refrigerant, natural gas liquefier
