专利汇可以提供Process for eliminating waste liquors accumulated in the desulfurization of coke oven gas专利检索,专利查询,专利分析的服务。并且A process for eliminating waste liquors accumulated in the desulfurization of coke oven gas with a washing solution containing an organic oxygen carrier includes evaporating between 30 and 70% of the water from the waste liquor to provide a concentrated waste liquor solution. The concentrated waste liquor is introduced into a combustion chamber with air and coke oven gas. The concentrated waste liquor is thermally decomposed in the combustion chamber and eliminated sulfur is separated from the gaseous products of combustion. The gaseous products of combustion are admixed with the coke oven gas evolved during the coking process.,下面是Process for eliminating waste liquors accumulated in the desulfurization of coke oven gas专利的具体信息内容。

1. A PROCESS FOR THE ELIMINATION OF WASTE LIQUORS ACCUMULATED IN THE DESULFURIZATION OF COKE OVEN GAS WITH A WASHING SOLUTION CONTAINING AN ORGANIC OXYGEN CARRIER COMPRISING, EVAPORATING BETWEEN ABOUT 30 AND 70% OF WATER FROM THE WASTE LIQUOR TO FORM A CONCENTRATED WASTE LIQUOR, INTRODUCING SAID CONCENTRATED WASTE LIQUOR INTO A COMBUSTION CHAMBER, INTRODUCING AIR INTO SAID COMBUSTION CHAMBER, INTRODUCING A SUFFICIENT AMOUNT OF COKE OVEN GAS TO PROVIDE A REDUCING ATMOSPHERE IN SAID COMBUSTION CHAMBER, THERMALLY DECOMPOSING SAID CONCENTRATED WASTE LIQUOR IN SAID COMBUSTION CHAMBER AND FORMING A LEAN GAS AND SULFUR, SEPARATING THE SULFUR FROM THE LEAN GAS, ADMIXING THE LEAN GAS WITH COKE OVEN GAS EVOLVED DURING A COKING PROCESS.
2. A process for the elimination of waste liquors accumulated in the desulfurization of coke oven gas with a washing solution containing an organic oxygen carrier as set forth in claim 1 which includes, introducing amonia vapors evolved in the treatment of coke oven gas with an excess of oxygen into said combustion chamber.
3. A process for the elimination of waste liquors accumulated in the desulfurization of coke oven gas with a washing solution containing an organic oxygen carrier as set forth in claim 2 which includes, evolving amonia vapors while evaporating the water from said waste liquor, admixing said amonia vapors with coke oven gas evolved during a coking process.
4. A process for the elimination of waste liquors accumulated in the desulfurization of coke oven gas with a washing solution containing an organic oxygen carrier as set forth in claim 1 in which, said air introduced into said combustion chamber includes air utilized in the oxidation of said waste liquor.
5. A process for the elimination of waste liquors accumulated in the desulfurization of coke oven gas with a washing solution containing an organic oxygen carrier as set forth in claim 1 which includes, cooling said lean gas in a waste heat boiler to provide steam for heating the waste liquor during the evaporation of wAter from said waste liquor.
