Heavy oil treating method and heavy oil treating system
First Claim
1. A heavy oil treating method comprising the steps of:
- contacting high-temperature, high-pressure water and heavy oil with each other;
after the lapse of a predetermined contact time, separating heavy oil components containing metals from light oil components dissolved in the high-temperature, high-pressure water by precipitation; and
burning or incinerating the separated heavy oil components.

Abstract
The invention is intended to produce high-pressure light fuel gas with good combustibility by contacting and reacting high-temperature, high-pressure water and heavy oil with each other in a contact-reaction unit to extract light oil components from the heavy oil and to remove metals. The high-temperature, high-pressure water and the heavy oil are introduced to the contact-reaction unit for contact and reaction with each other therein. Heavy oil components not dissolved in the high-temperature, high-pressure water are separated by precipitation from hydrocarbon gases and light oil components which are dissolved in the high-temperature, high-pressure water. The separated heavy oil components are burnt or incinerated without any further modification.

8. A heavy oil treating system comprising:
-
a nozzle for supplying heavy oil downward;
means for supplying high-temperature, high-pressure water alone or high-temperature, high-pressure water mixed with an oxidant at a level lower than said nozzle; and
a contact-reaction unit including means provided in an upper portion thereof for taking out light oil at a position away from said nozzle through which the heavy oil is supplied.

9. A heavy oil treating system comprising:
-
a contact-reaction unit for contacting high-temperature, high-pressure water and heavy oil with each other and separating the heavy oil into heavy oil components and light oil components by precipitation;
means for discharging the heavy oil components containing metals and precipitated in a bottom portion of said contact-reaction unit without dissolving in the high-temperature, high-pressure water; and
means for burning the heavy oil components extracted through said discharging means.
