METHOD FOR PROCESSING LIQUID HYDROCARBONIC PARAFFINIC RAW MATERIALS Russian patent published in 2021 - IPC C10G15/08 

FIELD: liquid hydrocarbon processing.

SUBSTANCE: invention relates to the field of preparation and primary processing of liquid hydrocarbon paraffinic raw materials. The invention relates to a method for processing liquid hydrocarbon paraffinic raw materials, including heating the raw material by mixing with a coolant or transferring heat through a separating baffle, hydrodynamic pulsation action, including cavitation action, the introduction of chemical reagents that activate the process of destruction of intermolecular and intramolecular bonds, separation of raw materials into a light low-boiling vapor-gas fraction and heavy liquid high-boiling fraction, their direction for further processing separately or in a mixture. Part of the light low-boiling steam-gas fraction is sent for mixing with the feedstock in the zones of hydrodynamic pulsation and cavitation treatment, where the flow of hydrocarbon paraffinic feedstock is subjected to at least two successive stages of hydrodynamic pulsation and cavitation effects, and substances are used as chemical reagents that in contact with each other react or decompose producing heat and gases. The heating of paraffinic hydrocarbon raw materials due to the heat of the coolant, hydrodynamic pulsation, cavitation effects and the heat of reactions of chemical substances is carried out to a temperature of no more than 90°С.

EFFECT: reduction of capital and operating, including energy, costs, an increase in the content of light hydrocarbons in the initial hydrocarbon feedstock, an increase in the reliability and controllability of the process of destruction of hydrocarbon compounds, simplification of the hardware design of the process of preparation of hydrocarbon paraffinic feedstock (HPF) for deep processing.
