METHOD OF KEROSENE FRACTIONS STABILIZING Russian patent published in 2014 - IPC C10G45/02 C10G7/02 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the processes of oil refining, in particular to methods of stabilizing of kerosene fractions. The invention relates to stabilizing of kerosene fractions by means of hot separation of gas product mixture from the hydrodemercaptanisation reactor into gas and liquid phases, pumping of the liquid phase as raw for the kerosene fractions stabilizing string, and also the gas phase cooling, condensation with the subsequent separation in the cold separator into hydrogen containing gas and liquid phase, which is supplied as a component for live reflux of the stabilizing string, meanwhile liquid phase of the hot separator is supplied to the stabilizing string after cooling, and a liquid phase of the cold separator without preheating is supplied as a component of live reflux of the top tray of the kerosene fractions stabilizing string.

EFFECT: stabilization of kerosene fractions at minimizing of the load on the condensation system, decrease of energy consumption for preheating of flows using the simple process layout with one raw flow, providing of required quality of raw materials for catalytic reforming.
