Abstract: Изобретение относится к области сжижения газов и их смесей. Природный газ высокого давления предварительно охлаждают и осушают. Далее отделяют часть прямого потока, расширяют и соединяют с обратным потоком. Прямой поток охлаждают, дросселируют и разделяют на паровую и жидкостную фазы в сборнике-сепараторе парожидкостной смеси. Паровую фазу из сепаратора разделяют на два потока. Первый поток направляют через регулятор давления газа в качестве обратного потока для охлаждения прямого потока. Второй поток повторно конденсируют за счет теплообмена с жидкостной фазой, которую направляют в обратный поток. Сконденсированную фазу дросселируют в сборник сжиженного газа с удалением паровой фазы. Разность температур между паром и жидкостью, необходимую для конденсации, обеспечивают или повышением давления пара, или понижением давления жидкости. Использование изобретения позволит получать сжиженный природный газ с малым содержанием высококипящих компонентов и диоксида углерода при низкой стоимости его очистки. 2 с. и 2 з.п. ф-лы, 2 ил., 1 табл.
