    • PURPOSE: The secondary solvent for removing solvent compound and a removing method of sulfur compound using the same are provided to remove sulfur compound with high efficiency from coal extract of low class coal, and reduce cost of the whole procedure by showing high desulfurization efficiency from a small amount of secondary solvent. CONSTITUTION: The secondary solvent for removing solvent comprises deionized water, hydrogen peroxide, methanol, ethanol, phentanol, and one or the compound selected from PGMEA. A removal method comprises the step of introducing the secondary solvent which acts as hydrogen donor to coal extract and removes sulfide compound within coal extract obtained from the coal extracting process of low class in a form of hydrogen sulfide gas. The secondary solvent is also used with one selected from reforming catalyst of metal oxide, metal hydroxide, activated charcoal, and transition metal or desulfurizing agent composed of the mixture. The desulfurizing agent is Ni group reforming catalyst.

    • PURPOSE: A capturing method of carbon dioxide and device thereof are provided to reduce the compressing cost for transferring ammonia gas, which is collected in an ammonia solution process in which the high pressure carbon dioxide is collected, to the removing tower of high pressure carbon dioxide, thereby increasing the collect rate of ammonia and the removal rate of carbon dioxide in the absorptive tower. CONSTITUTION: A capturing method of carbon dioxide uses an absorptive tower(3), a washing tower(13), a carbon dioxide removing tower(6), and an ammonia collecting tower(15). The absorptive tower selectively absorbs carbon dioxide from the combustion gas by using ammonia absorptive solution. The carbon dioxide removing tower removes the carbon dioxide from the ammonia solution, in which the carbon dioxide is absorbed, at high pressure. The ammonia collecting power separates the ammonia solution produced in the washing tower into the ammonia gas and water. The ammonia evaporating in the absorptive tower is supplied to the washing tower, is washed with cleaning water, and is transferred to the collecting tower. Vapor and ammonia gas mixture produced by being heated in the ammonia collecting tower are transferred to a heat exchanging partial condenser which is located on the top of the ammonia collecting tower. Vapor is condensed in the heat exchanging partial condenser and is recycled into the ammonia collecting tower, and the ammonia gas is recycled to the absorptive tower through an ammonia gas transferring pipe.

    • 目的:提供二氧化碳的捕获方法及其装置,以降低将收集在其中收集高压二氧化碳的氨溶液过程中收集的氨气转移到高压二氧化碳除去塔的压缩成本 ,从而提高吸收塔中氨的收集速率和二氧化碳的去除率。 构成:二氧化碳的捕获方法使用吸收塔(3),洗涤塔(13),二氧化碳除去塔(6)和氨收集塔(15)。 吸收塔通过使用氨吸收溶液从燃烧气体中选择性吸收二氧化碳。 二氧化碳去除塔在高压下从吸收二氧化碳的氨溶液中除去二氧化碳。 氨收集功率将洗涤塔中产生的氨溶液分成氨气和水。 在吸收塔中蒸发的氨被供应到洗涤塔,用清洗水洗涤,并被转移到收集塔。 通过在氨收集塔中加热产生的蒸汽和氨气混合物被转移到位于氨收集塔顶部的热交换部分冷凝器。 蒸汽在热交换部分冷凝器中冷凝,再循环到氨收集塔中,氨气通过氨气输送管再循环到吸收塔。 (附图标记)(2)燃烧废气
