Способ относится к газовой промышленности, в частности к технологии подготовки газа к дальнему транспорту. Сущность изобретения: способ обеспечивает снижение энергетических затрат в стадии охлаждения силикагеля и увеличение срока службы загрузки силикагеля путем сокращения времени охлаждения в конце ее эксплуатации. Способ адсорбционной осушки природного газа предусматривает проведение одновременно осушки природного газа в одном адсорбере и регенерации компримированным газом силикагеля в другом адсорбере. Для этого после регенерации силикагеля второй адсорбер подключают параллельно первому и за счет перепада давлений на входе и выходе первого адсорбента ведут охлаждение силикагеля второго адсорбера сырым ненагретым газом, взятым из линии природного газа. Расход сырого газа составляет от 2 до 50% расхода газа осушки. Технический результат достигается за счет того, что используется гидравлическое сопротивление, возникающее при прохождении потока осушаемого газа через слой силикагеля в одном из адсорберов, создавая потери давления, иными словами, перепад давления входа и выхода, который используется для создания циркуляции ненагретого газа через второй адсорбер для его охлаждения.The method relates to the gas industry, in particular to the technology of gas preparation for long-distance transport. The inventive method reduces energy costs in the stage of cooling silica gel and increase the service life of the silica gel load by reducing the cooling time at the end of its operation. The method of adsorptive dehydration of natural gas provides for the simultaneous dehydration of natural gas in one adsorber and regeneration of silica gel with compressed gas in another adsorber. To this end, after the silica gel is regenerated, the second adsorber is connected in parallel to the first one and due to the pressure drop at the inlet and outlet of the first adsorbent, the silica gel of the second adsorber is cooled with raw unheated gas taken from the natural gas line. The consumption of raw gas ranges from 2 to 50% of the flow of drying gas. The technical result is achieved due to the fact that hydraulic resistance is used that occurs when a stream of dried gas passes through a layer of silica gel in one of the adsorbers, creating pressure losses, in other words, inlet and outlet pressure drops, which are used to create unheated gas circulation through the second adsorber its cooling.
