Изобретение может примен тьс в ироцеесах сжижени газа или газовых смесей, например ириродного газа, с ломощыо онределенного многокомнонетного летучего холодильного агента, отдельные фракции которого конденснруютс но мере ноннжени темнературы и таким образом охлал дают и сжижают газ или газов 1О смесь путем теплообмена.The invention can be used in liquefaction gas or gas mixtures, for example, iridescent gas, from a multi-carbon volatile refrigerant razor, the individual fractions of which condense but not only temperatury temperatur and thus cooled and liquefy the gas or gases 1O by heat exchange.
Известеп способ регулировани температуры сжиженного газа путем нз.мененн расхода мпогокомпоиентного летучего хладагента с учетом состава хладагента.A known method of controlling the temperature of a liquefied gas by means of the change in consumption of a multi-component volatile refrigerant, taking into account the composition of the refrigerant.
Однако известный способ прнводнт к регулированию состава охлаждаюн ей жидкости - хладагента, определение которого требует большой точности и длительности времени.However, there is a known method of pre-watering to adjusting the composition of a cooling liquid - a refrigerant, the determination of which requires great accuracy and length of time.

Количество этажей в колонне может мен тьс , но нредпочтнтельно д.п конденсационной колонны - два -четыре этажа и трн-н ть этажей дл обменной.floors, and exchanged - - from two to four. The number of floors in a column can vary, but preferably the size of a condensation column is two to four floors and one to three floors for an exchange tower.
Пары хладагента нз обменной колонны 2 ионадают в компрессор 3 ннзкого давлени , а затем через охладитель-конденсатор 4 в комнрессор 5 высокого давленн , сюда также ионадают иары хладагента из конденсационной колонны . Сжатые нары из комнрессора 5 нонадают в конденсатор и, где охлаждаютс и частично конденснруютс . Конденсатор b охлаждаетс снаружи воздухом или, нанример. морской водой.The refrigerant vapors of the exchange column 2 are ionized into the compressor 3 of a low pressure, and then through the cooler-condenser 4 to the high-pressure compressor 5, here also the refrigerant vapor from the condensation column is ionized. Compressed bunks from the compressor 5 are pushed into the condenser and where they are cooled and partially condensed. Condenser b is cooled externally with air or, eg. sea water.
Смесь жидкости и паров поступает из коиденсатора 6 в баллон 7, расположенный на ypOBEie первого (нижнего) этажа конденсациOHHoii колонны 1, где нары и жидкость раздел ютс . Часть жидкости поступает в обменникThe mixture of liquid and vapor enters from the co-condenser 6 into the cylinder 7, located on the ypOBEie of the first (lower) floor of the condensation of OHHoii column 1, where the bunks and liquid are separated. Part of the liquid enters the exchanger

часть - в обменник 9 первого этажа обменной колонны 2.part - in the exchanger 9 of the first floor of the exchange column 2.
Пройд через обменник 8, жидкость поступает в форсунк} 10, котора вирыскивает ее в конденсационную колонну дл охлаждени жидкости в обменнике У, а также дл частичного конденсировани газа, поступающего из баллона 7 в обменник И. Жидкость, проход ща через обменник 9 обменной колонны, впрыскиваетс форсункой 2 п эту колонну и охлаждает жидкость в об.меннике 9 и сжижаемый газ в обменпике 13. Перед входом в обменную колонну 2 этот газ частично сжимаетс компрессором 14.Passing through the exchanger 8, the liquid enters the nozzle} 10, which sprays it into the condensation column to cool the liquid in the exchanger U, as well as partially condensing the gas coming from the cylinder 7 into the exchanger I. The liquid passing through the exchanger 9 of the exchange column the nozzle 2p injects this column and cools the liquid in the exchange bar 9 and the liquefied gas in the exchange point 13. Before entering the exchange column 2, this gas is partially compressed by the compressor 14.
На остальных этажах конденсационной и обменной колонн иовтор етс тот же самый процесс, что и иа первых. Из обменника 11 фракци хладагента поступает в баллон 15 на уровне нервого этажа, где распадаетс на жидкую и газообразную фазы. На этом этаже конденсационной колонны расположен об ..менник 16 соединенный на выходе с форсункой 17, и обменник 18 дл конденсируемых паров . В обменной колонне на этом же этаже расположен обменник 19 с форсункой 20 дл охлаждени жидкости и обмепник 21 дл сжижаемого газа. На третьем, последнем этаже конденсационной колонны, раснолагаетс баллон 22, обменники 23 и 24 и форсунка 25, а на третьем этаже обменной колонны установлен обменник 26, форсунка 27 и обменник 28 дл сжиЛСаемого газа. Пары хладагеита конденсируютс в обменнпке 24 и поступают в последний этаж обменной колонны, в обменник 29, а затем в форсунку 30. Этим обеспечиваетс охлаждение и конденсаци сжижаемого газа в последнем обменпике 31.On the remaining floors of the condensation and exchange columns, the same process as the first is repeated. From the exchanger 11, the refrigerant fraction enters the cylinder 15 at the level of the nerve floor, where it disintegrates into liquid and gaseous phases. On this floor of the condensation column there is an oblamennik 16 connected at the outlet with the nozzle 17, and an exchanger 18 for condensable vapors. In the exchange column on the same floor there is an exchanger 19 with a nozzle 20 for cooling the liquid and a rim 21 for the liquefiable gas. On the third and last floor of the condensation column, there is a cylinder 22, exchangers 23 and 24 and nozzle 25, and on the third floor of the exchange column there is an exchanger 26, nozzle 27 and an exchanger 28 for liquefied gas. The refrigerant vapor is condensed in exchange 24 and transferred to the last floor of the exchange column, to the exchanger 29, and then to the nozzle 30. This ensures cooling and condensation of the liquefied gas in the last exchange peak 31.
Выход щий из обменной колонны 2 сжиженный газ через вентиль 32, регулирующий давление, поступает в емкости дл хранени (на чертеже не показаны). Предпочтительное давление при хранении сжиженного газа близко к атмосферному давлению.The liquefied gas leaving the exchange column 2 through the pressure regulating valve 32 enters the storage tanks (not shown). The preferred pressure during storage of liquefied gas is close to atmospheric pressure.
Мелсду обменником 23 и форсу.пкой 25 и между обменником 29 и форсункой 30 установлены два вентил 33 п 34 соответственно. Первый вентиль регулирует расход жидкости, необходимой дл образовагги нужного количества паров при наиболее низкой температуре в конденсационной колонне 1. Второй- дл регулировани впрыскиваемой в обменпую колонну 2 жидкости, выход и1ей из обменпика 29. Вентиль 35 регулирует количество допо .пнительных составл ющих, которые добавл ютс в газообразном состо нии к парам, после теплообмеиа поступающим в колшрессор 3. Такими добавками могут быть два вида газов , имеющих наиболее низкую температуру конденсации. правило, это азот и метай. В случае слсиженп природного газа такой добавкой в процессе его сжилсени может быть смесь, полученна из самого природного газа.Melsdu exchanger 23 and the injector. 25 and between the exchanger 29 and nozzle 30 are installed two valves 33 and 34, respectively. The first valve controls the flow rate required to form the required amount of vapor at the lowest temperature in the condensation column 1. The second, to regulate the liquid injected into the exchange column 2, out of the exchange 29. The valve 35 controls the amount of additional components that are added in the gaseous state to the vapors, after the heat uptake, entering the collapsor 3. Such additives can be two types of gases having the lowest condensation temperature. it's usually nitrogen and methane. In the case of natural gas slurry, such an additive during its compression may be a mixture obtained from the natural gas itself.

Wentpl 35 serves to determine the temperature of the refrigerant after injection by introducing additives into the refrigerant. The temirature after fusion is measured by a zoide 38. By measuring the pressure of the co-compressor 3, the pressure is calculated by the refrigerant pressure in the exchange colony, and the gas is expelled and gas in the gaseous state. This pressure gauge is measured by a pressure gauge 39.
