FIELD: heating.
SUBSTANCE: invention relates to devices for gas treatment, in particular to a structure of separation devices. The fractionating refrigerator-capacitor consists of a reflux column and a separation section adjacent to it from below. The reflux column and the separation section enclose a feeding zone between them, equipped with a line of feed gas input. Between the feeding zone and the reflux column the gas distribution device is located. The reflux column is equipped with a line of input of cooled commercial gas and lines of output of separation gas and commercial gas. The reflux column is equipped with unit of heat and mass exchange elements. The line of input of cooled commercial gas is located in the upper part, and the line of output of commercial gas is located in the lower part of the unit of heat and mass exchange elements. The separation section is equipped with output lines of unstable condensate and aqueous solution of hydrate generating inhibitor.
EFFECT: reduction of losses of heavy components and reduction of metal consumption is ensured.
