Abstract

1. Способ низкотемпературного разделения газовой смеси на компоненты, содержащий подачу в исходную газовую смесь хладагента, ступенчатое охлаждение смеси и выделение газовых компонентов, при котором низкотемпературный хладагент является частью жидкой фазы газового компонента после одной из стадии охлаждения, отличающийся тем, что выделение компонентов осуществляют из потока газовой смеси путем прямого введения на каждой стадии охлаждения непосредственно в поток газовой смеси низкотемпературного хладагента, являющегося продуктами разделения газовой смеси, полученными на каждой стадии охлаждения смеси и выделения компонентов, при этом часть каждого полученного продукта разделения доохлаждают с использованием внешнего холода, после которого возвращают напрямую на все стадии охлаждения газовой смеси и выделения газовых компонентов, причем поток газовой смеси, прошедший все стадии охлаждения и выделения компонентов, доохлаждают с использованием внешнего холода и возвращают напрямую на предыдущие стадии охлаждения смеси и выделения компонентов, образуя многократные циклы движения и охлаждения потока газовой смеси.2. Способ по п.1, отличающийся тем, что хладагент может быть однокомпонентным и/или более низкокипящим газом, являющимся смесью выделенных жидких газовых компонентов.3. Способ по п.1 или 2, отличающийся тем, что жидкую фазу газа, извлеченную при более низких температурах, чем температура ее кипения, возвращают на более ранние стадии охлаждения в качестве хладагента.1. A method of low-temperature separation of a gas mixture into components, comprising supplying a refrigerant to the initial gas mixture, stepwise cooling the mixture and isolating gas components, wherein the low-temperature refrigerant is part of the liquid phase of the gas component after one of the cooling stage, characterized in that the components are separated from the flow of the gas mixture by direct introduction at each stage of cooling directly into the gas mixture stream of low-temperature refrigerant, which is the product the separation of the gas mixture obtained at each stage of cooling the mixture and the separation of components, while part of each obtained separation product is cooled using external cold, after which it is returned directly to all stages of cooling the gas mixture and the separation of gas components, the gas mixture flow passing through all stages cooling and isolating the components, further cooling using external cold and returning directly to the previous stages of cooling the mixture and isolating the components, forming multiple different cycles of movement and cooling of the gas mixture flow. 2. The method according to claim 1, characterized in that the refrigerant may be a single component and / or lower boiling gas, which is a mixture of the separated liquid gas components. The method according to claim 1 or 2, characterized in that the liquid phase of the gas recovered at lower temperatures than its boiling point is returned to earlier stages of cooling as a refrigerant.
