SYSTEM AND METHOD OF MANAGEMENT AND OPTIMISATION OF HYDROTHERMAL PROCESS OF HEAVY OIL AND BITUMEN REFINEMENT Russian patent published in 2017 - IPC C10G31/08 B01J19/18 

FIELD: oil and gas industry.

SUBSTANCE: system contains a fluid flow route formed to continuously deliver the process stream along this route in the direction of flow. The flow route includes a reactor, a reactor configured to receive a process stream with water at an inlet temperature in the range of about 60 to 200°C, a reactor including one or more pressure pipes defining the total cross-sectional dimension of the flow inside pipes across the flow. The total length of one or more pressure pipes is at least 30 times more than total cross-sectional dimension of the flow inside the pipes, a reactor configured to supply heat to the process flow passing therethrough so as to gradually increase the flow temperature at the reactor inlet to the outlet temperature T(max)1 in the range of about 260-400°C at the reactor outlet. At that reactor is arranged to maintain a pressure in the process stream sufficient to provide a single-phase flow of the process stream at T(max)1, the controller is configured to selectively control the flow rate of the process stream through the reactor in order to maintain the total contact time of the process stream of feedstock in the reactor within an interval of about 1 to 25 minutes. Said flow rate, said lengths of the pressure pipes and said heat supply ensure minimization or prevention of coke formation.

EFFECT: use of the proposed invention enables maximizing the efficiency and degree of refiniment at the highest temperatures, minimizing adverse reactions of coke formation.
