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.

Claims (17)

1. A heavy oil treating system comprising:

a contact-reaction unit, high temperature and high pressure water and heavy oil being supplied to said contact-reaction unit, said contact-reaction unit being arranged so as to flow said high temperature and high pressure water and heavy oil in a vertical direction;

a nozzle arranged at an upper side of said contact-reaction unit, being parallel to said vertical direction to flow said high pressure water and heavy oil in said contact-reaction unit, supplying heavy oil to said contact-reaction unit downwardly in a direction parallel to said vertical direction;

supplying means for supplying high temperature and high pressure water or oxidant mixed with high temperature and high pressure water to said contact-reaction unit, being arranged at lower side of said contact-reaction unit; and

extraction means for extracting a light oil from said contact-reaction unit, being arranged at an upper portion of said contact-reaction unit, an arranged portion of said extraction means being different from an arranged portion of said nozzle.

2. A heavy oil treating system comprising:

a contact-reaction unit, high temperature and high pressure water and heavy oil being supplied to said contact-reaction unit, said contact-reaction unit being arranged so as to flow said high temperature and high pressure water and heavy oil in a vertical direction;

a nozzle arranged at an upper side of said contact-reaction unit, being parallel to said vertical direction to flow said high pressure water and heavy oil in said contact-reaction unit, supplying heavy oil to said contact-reaction unit downwardly in a direction parallel to said vertical direction, a top end of said nozzle being arranged at a position lower than an upper side of said contact-reaction unit;

supplying means for supplying high temperature and high pressure water or oxidant mixed with high temperature and high pressure water to said contact-reaction unit, being arranged at lower side of said contact-reaction unit; and

extraction means for extracting a light oil from said contact-reaction unit, being arranged at an upper portion of said contact-reaction unit, an arranged portion of said extraction means being different from an arranged portion of said nozzle.

3. A heavy oil treating system comprising:

a contact-reaction unit, high temperature and high pressure water and heavy oil being supplied to said contact-reaction unit, said contact-reaction unit being arranged so as to flow said high temperature and high pressure water and heavy oil in a vertical direction;

a nozzle arranged at an upper side of said contact-reaction unit, being parallel to said vertical direction to flow said high pressure water and heavy oil in said contact-reaction unit, supplying heavy oil to said contact-reaction unit downwardly in a direction parallel to said vertical direction;

supplying means for supplying high temperature and high pressure water or oxidant mixed with high temperature and high pressure water to said contact-reaction unit, being arranged at lower side of said contact-reaction unit;

extraction means for extracting a light oil from said contact-reaction unit, being arranged at an upper portion of said contact-reaction unit, an arranged portion of said extraction means being different from an arranged portion of said nozzle;

a discharging means for discharging heavy oil components containing metals precipitated in a bottom portion of said contact-reaction unit without dissolving in the high temperature and high pressure water; and

burning means for burning said heavy oil components discharged from said discharge means.
