The above leads to. reduce the effectiveness of the process of rescue.
Цель изобретения - повышение экономичности процесса сжижения за счет снижения расхода газа на подог5 рев, расхода энергии на сжатие регенерационного газа и более эффективного использования топливного газа.The purpose of the invention is to increase the efficiency of the liquefaction process by reducing gas consumption for heating, energy consumption for compression of regeneration gas and more efficient use of fuel gas.
Указанная цель'достигается тем, что согласно способу сжижения .при10 родного газа, включающему сжатие газа в компрессоре с газовым приводом, глубокую осушку его цеолитами, охлаждение осушенного газа хладагентом внешнего паро-компрессионного холодильного цикла, выделение в процессе охлаждения углеводородов и выше и их нагрев путем рекуперативного теплообмена с охлаждаемым природным газом, последующие сжижение газа, нагрев части осушенного газа для* регенерации цеолитов выхлопными^ газами приводов компрессоров, смешивание ' газа после регенерации цеолитов с выделенными углеводородами С& и выше и подачу полученной смеси в газо25 ные приводы компрессоров, газ после.This goal is achieved by the fact that according to the method of liquefying natural gas, which includes compressing the gas in a gas-driven compressor, deep drying it with zeolites, cooling the dried gas with an external vapor-compression refrigeration cycle, and releasing hydrocarbons and above during heating and heating them by recuperative heat exchange with cooled natural gas, subsequent gas liquefaction, heating part of the dried gas for * regeneration of zeolites by exhaust ^ gases of compressor drives, mixing 'gas after p generating zeolites with selected hydrocarbons and C & above and feeding the resulting mixture into gazo25 nye compressor drives, gas after.

На чертеже представлена технологическая схема сжижения природного газа.The drawing shows a flow diagram of the liquefaction of natural gas.
Газ от месторождения поступает Ю в компрессор .1 с приводом 2 от газовой турбины или поршневого газового двигателя. Сжатый газ направляют в адсорбер 3, где осуществляют его осушку. Часть осушенного газа отво- 15 дят в адсорбер 4, прошедший стадию регенерации, для охлаждения цеолита. Из адсорбера 4 газ подают на регенерацию цеолита в адсорбере 5, предварительно нагревая его продук- 2θ тами сгорания привода компрессоров в теплообменнике б. Из адсорбера 5 газ регенерации подают в привод 2 компрессора 1 и (или) в газовый двигатель 7 компрессора 8 хладагента 2^ в качестве топлива. Поток газа из адсорбера 3 Направляют в теплообменник 9, где охлаждают, конденсируют й переохлаждают холодильным агентом, сжатым в компрессоре 8. Фракции С^ и выше выделяют из сжиженного газа в сепараторе 10. Сжиженный газ подают в резервуар 11 и далее, например, в танкеры 12. Реку.1ерируют холод подогрева выделенной жидкости в теплообменнике 9, образовавшуюся смесь 55 разделяют в сепараторе 13.Gas from the field enters Yu into the compressor .1 with drive 2 from a gas turbine or reciprocating gas engine. Compressed gas is sent to adsorber 3, where it is dried. Part of the dried gas is taken off to adsorber 4, which has passed the regeneration stage, to cool the zeolite. From adsorber 4, gas is fed to the regeneration of zeolite in adsorber 5, preheating it with the products of 2 θ combustion products of the compressor drive in the heat exchanger b. From the adsorber 5, the regeneration gas is supplied to the drive 2 of the compressor 1 and / or to the gas engine 7 of the compressor 8 of the refrigerant 2 ^ as fuel. The gas stream from the adsorber 3 is sent to the heat exchanger 9, where it is cooled, condensed and subcooled with a refrigerant compressed in the compressor 8. Fractions C ^ and higher are separated from the liquefied gas in the separator 10. The liquefied gas is supplied to the tank 11 and then, for example, to tankers 12. River 1. The cold of heating the separated liquid in the heat exchanger 9 is generated, the resulting mixture 55 is separated in the separator 13.
Газ-* регенерации, который выводят из адсорбера 5, смешивают с фракциями, или их частью, выделенными в сепараторе 13; и с помощью эжектора 40 14 с газом, испаряющимся из резервуара 11. Адсорберы 3-5 периодически переключают. 'Гак, например, через определенный промежуток времени осушку газа осуществляют в адсорбере 4, 45 адсорбер 5 охлаждают, а. адсорбер 3 регенерируют.Regeneration gas *, which is removed from the adsorber 5, is mixed with the fractions, or part thereof, separated in the separator 13; and using an ejector 40 14 with gas evaporating from the reservoir 11. The adsorbers 3-5 are periodically switched. 'Hack, for example, after a certain period of time, the gas is dried in the adsorber 4, 45 the adsorber 5 is cooled, as well. adsorber 3 regenerate.
Смешение отсепарированных и предварительно нагретых фракций Cj и выше с регенерационным газом и исполь- 5Q зование смеси в качестве топливного газа позволяет повысить экономичность процесса сжйжения за счет' снижения, по сравнению с прототипом расхода энергии (исключение из схемы 55 компрессора) на дожатие регенерационного газа до исходного давления; .повышения температуры газа на входе в привод компрессора: из адсорберов газ выходит с температурой около 200°С; снижения расхода энергии, по сравнению с прототипом, на охлаждение регенерационного газа перед его возвращением в цикл; более эффективной работы привода компрессоров вследствие подачи в камеры сгорания'·1 увлажненного газа.Mixing the separated and preheated fractions of Cj and higher with regeneration gas and using the mixture as fuel gas 5Q improves the efficiency of the liquefaction process due to a reduction in energy consumption compared to the prototype (exclusion from compressor circuit 55) to pressurize regeneration gas to initial pressure; Increases in gas temperature at the inlet to the compressor drive: gas leaves the adsorber at a temperature of about 200 ° C; reducing energy consumption, compared with the prototype, for cooling the regeneration gas before it returns to the cycle; more efficient operation of the compressor drive due to the supply of moistened gas to the · · 1 combustion chamber.
Нагрев регенерационного газа выхлопными газами привода компрессоров позволяет повысить эффективность процесса сжижения за счет сокращения расхода энергии на питание нагревательных устройств.The heating of the regeneration gas by the exhaust gases of the compressor drive makes it possible to increase the efficiency of the liquefaction process by reducing the energy consumption for heating devices.
Температура газов на выходе из турбины составляет 420-480°С, причем большие значения соответствуют турбинам мощностью более 20 кВт, применяемым в составе крупных установок сжижения газа. Расход продуктов сгорания на выходе из турбины уже при уровне мощности 10-12 МВт составляет 55-75 кг/с, что более чем достаточно для организации нагрева соответствующего количества газа для регенерации цеолитов при разности температур между продуктами сгорания и газом 50-100°C (газ для регенерации цеолитов нагревают до 200-380 °C).The temperature of the gases at the outlet of the turbine is 420-480 ° C, and large values correspond to turbines with a capacity of more than 20 kW used in large gas liquefaction plants. The consumption of combustion products at the turbine exit already at a power level of 10-12 MW is 55-75 kg / s, which is more than enough to organize the heating of an appropriate amount of gas for zeolite regeneration at a temperature difference between combustion products and gas of 50-100 ° C ( gas for the recovery of zeolites is heated to 200-380 ° C).
Предложенный способ позволяет снизить расход газа на собственные нужды на 10-20%. Его особенно целесообразно использовать на крупных установках сжижения природного газа, например, с целью последующего транспорта сжиженного природного газа танкерами-метановозами.The proposed method allows to reduce gas consumption for own needs by 10-20%. It is especially advisable to use it in large natural gas liquefaction plants, for example, for the purpose of subsequent transport of liquefied natural gas by methane tankers.
