DEVICE FOR SEPARATION OF THE NATURAL GAS INTO THE FRACTIONS Russian patent published in 2007 - IPC B01D3/32 F25J3/02 

FIELD: mechanical engineering; oil-processing industry; gas-processing industry; devices for separation of the gases into fractions.

SUBSTANCE: the invention is pertaining to the field of mechanical engineering, in particular, to the process engineering of separation of the natural gas into fractions, for example, at reprocessing of the oil gases by the low-temperature condensation and may be used in the oil-processing industry and the natural gas-processing industry. The most preferable is usage of the presented device in the capacity of the deethanizer or the demethanizer. The device for separation of the gas into the fractions is made in the form of the distillation column consisting of two communicating to each other sections - the upper section and the lower section. The column has two inlets, one of which is arranged in the lower section, and another - in the upper section, and two outlets. The device contains the drips-deflector and the cooler arranged in the upper part of the upper section, the tubular components made in the form of the spiral used for the sections communication to each other and arranged in the lower part of the upper section. The sections are divided by the partition with the holes used for arrangement of the ends of the tubular components and outlets are arranged in the upper and the lower parts of the upper section accordingly. The cooler is made in the form of the hollow cylinder from the external side of which there is the tubular coil used for the coolant. The drips-deflector consists of the lower and upper cylinders, at that the upper cylinder has the smaller diameter and is arranged in the lower cylinder with the clearance concerning the bottom of the lower cylinder forming the labyrinth for passage of the fraction of the gas, and the lower cylinder has the hole for the gas withdrawing pipeline. The device is supplied with the components for condensation of the liquid and is made in the form of the feed screws arranged inside the spiral of the tubular components. The invention ensures simplification of the design of the device at improvement of the quality of separation of the hydrocarbon-containing raw.

EFFECT: the invention ensures simplification of the design of the device at improvement of the quality of separation of the hydrocarbon-containing raw.
