METHOD FOR PURIFYING GASIFIED GAS AND APPARATUS FOR PURIFYING THE GASIFIED GAS

摘要

PROBLEM TO BE SOLVED: To provide a method for purifying a gasified gas, by which high boiling point hydrocarbon compounds released from activated carbon can effectively be used to recover the adsorption capacity of the activated carbon adsorbed with the high boiling point hydrocarbon compounds in the gasified gas, and to provide an apparatus for purifying the gasified gas.;SOLUTION: This method for purifying a gasified gas, comprising passing the gasified gas obtained by thermally cracking solid organic materials such as organic wastes or coal in a gasification oven 2 through an activated carbon type adsorption device 1 comprising activated carbon adsorption towers 1a, 1b to make the activated carbon to adsorb dioxins and high boiling point hydrocarbon compounds liquid or solid at ordinary temperature and at atmospheric pressure in the gasified gas, releasing and recovering the high boiling point hydrocarbon compounds adsorbed on the activated carbon in the activated carbon adsorption towers 1a, 1b, and then blowing the recovered high boiling point hydrocarbon compounds in a gasification oven 2 or a combustion furnace 2a for supplying heat in the gasification oven, is characterized by controlling the amounts of the high boiling point hydrocarbon compounds in the gasification oven 2 or the combustion furnace 2a in response to a separately measured gasification oven operation state.;COPYRIGHT: (C)2009,JPO&INPIT
