SUPERCRITICAL MULTI-ELEMENT HOT FLUID GENERATION SYSTEM AND METHOD WITH SEGMENTED AIR SUPPLY

WIPO Patent Application WO/2022/227837

A1

A supercritical multi-element hot fluid generation system with segmented air supply. An outlet of a water tank (12) of the system is in communication with a preheated water inlet of a multi-element hot fluid generator body (22), a preheated water outlet of the multi-element hot fluid generator body is in communication with a cold fluid inlet of a heat exchanger (6), a product outlet on an upper portion of the multi-element hot fluid generator body is in communication with an inlet for a heat exchanger hot fluid, and a residue outlet on a lower portion of the multi-element hot fluid generator body is in communication with an inlet of a residue discharge lock hopper (14). By means of the rational coupling design of a supercritical water gasification heat absorption area and a hydrogen oxygen heat release area in a multi-element hot fluid generator, the system is self-heated, and high apparatus investment and operation costs caused by an electric heating apparatus are reduced; and a rational desalination solution is provided, so as to prevent the system from being blocked such that the system can be applied to an offshore heavy oil thermal recovery system. Further disclosed is a supercritical multi-element hot fluid generation method with segmented air supply which uses the system.
