Title:
DEVICE FOR REFORMING HEAVY OIL AND METHOD OF REFORMING HEAVY OIL
Document Type and Number:
WIPO Patent Application WO/2011/048642
Kind Code:
A1
Abstract:
A device and method for reforming a heavy oil are provided with which it is possible to control the degree of progress of the thermal cracking of the heavy oil when the heavy oil is reformed using supercritical water.
A reactor (1) is kept at a temperature and a pressure which are equal to or higher than the critical points of water, and a heavy oil is brought into contact with supercritical water. While thermal cracking of the heavy oil is allowed to proceed, the reaction mixture is separated into a first phase comprising heavy-oil matter obtained by the thermal cracking of the heavy oil and supercritical water dissolved in the heavy-oil matter and a second phase comprising supercritical water and light-oil matter extracted and dissolved in the supercritical water. An interface detector (75) detects the level of the interface between the first phase and the second phase in the reactor. A control unit (7) controls, on the basis of the volume of the first phase determined from the level of the interface, the discharge rate of the mixed fluid composed of the heavy-oil matter and the supercritical water dissolved therein, so that the residence time of the heavy-oil matter/supercritical water mixed fluid is a first residence time preset.
