Title:
SUPERCRITICAL REACTION SYSTEM AND PROCESS FOR UPGRADING PETROLEUM
Document Type and Number:
Japanese Patent JP2019002012
Kind Code:
A
Abstract:
To provide a supercritical upgrading reactor for upgrading a petroleum-based composition.SOLUTION: A supercritical upgrading reaction system of the present invention comprises one or more active supercritical upgrading reactors, which is executing a reforming work and one or more stand-by supercritical upgrading reactors, which is executing other than a reforming work. The supercritical upgrading reactors operates at a temperature greater than the critical temperature of water and at a pressure greater than the critical pressure of water. The supercritical upgrading reaction system also comprises one or more controllers connected to at least one of one or more active supercritical upgrading reactors and at least one of one or more stand-by supercritical upgrading reactors for alternatively changing active or stand-by state of the supercritical upgrading reactors so that ; one stand-by supercritical upgrading reactor is changed to be active and reforms a combined feed stream; and another active supercritical upgrading reactor is changed to be stand-by and executes a cleaning operation by delivering a cleaning fluid.SELECTED DRAWING: None
