Abstract

A hydrocarbon recovery facility includes: a washing column configured to bring a gas and water into contact to deposit a hydrocarbon contained in the gas into the water; an automatic strainer for continuously removing the hydrocarbon together with part of the water from the water mixed with the hydrocarbon; an oil-water mixing drum for mixing the water and the hydrocarbon removed by the automatic strainer with an organic solvent to prepare an oil-water mixture; and an oil-water separation drum for separating the oil-water mixture prepared in the oil-water mixing drum into an oil phase and a water phase.

First claim

The invention claimed is:

1. A hydrocarbon recovery facility comprising:
a washing column configured to bring a gas and water into contact to deposit a hydrocarbon contained in the gas into the water;
an automatic strainer of scraping type that continuously removes the hydrocarbon together with part of the water from the water mixed with the hydrocarbon by scraping substances collected on a fixed element with a brush scraper to remove them to an outside;
an oil-water mixing drum for mixing the water and the hydrocarbon removed by the automatic strainer with an organic solvent to prepare an oil-water mixture; and
an oil-water separation drum for separating the oil-water mixture prepared in the oil-water mixing drum into an oil phase and a water phase.

2. The hydrocarbon recovery facility according to claim 1 , wherein the oil-water mixing drum includes an agitator.

3. The hydrocarbon recovery facility according to claim 1 , wherein the organic solvent is flammable.

4. The hydrocarbon recovery facility according to claim 3 , wherein the organic solvent is kerosene, light oil, anthracene oil, or creosote oil.

5. The hydrocarbon recovery facility according to claim 1 , wherein the gas is syngas obtained by gasification of coal.
