DEVICE FOR FRACTIONATION OF HEAVY HYDROCARBONS Russian patent published in 2014 - IPC B01D3/14 C10G7/00 

FIELD: process engineering.

SUBSTANCE: invention relates to heat-and-mass exchange in gas-fluid system and can be used at oil processing plants. Proposed device comprises body with pipes discharging processed fluid and feeding that to be processed connected to body still bottom, heat exchanger arranged at said still bottom and communicated with body top via the line feeding fluid flow from above to system of nozzles. Said heat exchanger is composed of tubular adapter including pipes with their top sections equipped with film-forming elements arranged between top and bottom tube plates secured at body still bottom. Initial fluid feed pipe and line feeding the flow from above to said system of nozzles are communicated with space between said tube plates. Said system of nozzles is equipped with atomiser to create a continuous film curtain over the body cross-section. System of nozzles comprises at least two horizontal jet trays and at least two sections of vertical jet trays arranged there under one above the other.

EFFECT: higher efficiency of heat exchange.
