Title:
METHOD FOR COLLECTING HYDROCARBON COMPOUND FROM GASEOUS BY-PRODUCT AND APPARATUS FOR COLLECTING HYDROCARBON
Document Type and Number:
WIPO Patent Application WO/2010/098129
Kind Code:
A1
Abstract:
Disclosed is a method for collecting a hydrocarbon compound from a gaseous by-product that is produced in a Fischer-Tropsch synthesis reaction. The method for collecting a hydrocarbon compound comprises: a step wherein a light hydrocarbon compound and carbon dioxide gas contained in the gaseous by-product are absorbed by an absorption solvent that contains a liquid hydrocarbon compound and a carbon dioxide gas absorbent; a step wherein the absorption solvent containing the light hydrocarbon compound and the carbon dioxide gas is separated into the liquid hydrocarbon compound and the carbon dioxide gas absorbent; a step wherein the separated liquid hydrocarbon compound is heated for the purpose of collecting the light hydrocarbon compound from the separated liquid hydrocarbon compound; a step wherein the separated carbon dioxide gas absorbent is heated for the purpose of releasing the carbon dioxide gas from the separated carbon dioxide gas absorbent; and a step wherein the gaseous by-product, from which the light hydrocarbon compound and the carbon dioxide gas are absorbed and removed, is reused as a starting material gas for the Fischer-Tropsch synthesis reaction.
