    • The invention relates to a method for removing gas components SOX, NOx, and CO2 from a flue gas, comprising the steps of: a) contacting the flue gas with a first liquid medium which provides a first plasma containing reactive electrons or ions in an amount such that the gas molecules SOX are subject to impingement of the electrons or ions in the first plasma to enable the dissociation of the gas molecules SOX so as to remove SOx from the flue gas; b) contacting the flue gas obtained from step a) with a second liquid medium which provides a second plasma containing reactive electrons or ions in an amount such that the gas molecules CO2 are subject to impingement of the electrons or ions in the second plasma to enable the dissociation of the gas molecules CO2 so as to remove CO2 from the flue gas; and c) contacting the flue gas obtained from step b) with a third liquid medium which provides a third plasma containing reactive electrons or ions in an amount such that the gas molecules NOx are subject to impingement of the electrons or ions in the second plasma to enable the dissociation of the gas molecules NOx so as to remove NOx from the flue gas. The invention also relates to a system for removing gas components SOX, NOx, and CO2 from a flue gas. The method and the system of the invention significantly reduce the capital cost and require very low energy, with the environmentally friendly final products. In addition, the tower of the invention can be constructed in a very compact manner.
    • 本发明涉及一种从烟道气中除去气体组分SOX,NOx和CO2的方法,包括以下步骤:a)使烟气与第一液体介质接触,第一液体介质提供含有反应性电子或离子的量的第一等离子体, 使得气体分子SOX在第一等离子体中受到电子或离子的撞击,以使气体分子SOX解离,从而从烟道气中除去SOx; b)将从步骤a)获得的烟道气与第二液体介质接触,所述第二液体介质提供包含反应性电子或离子的第二等离子体,其量使得气体分子CO 2在第二等离子体中受到电子或离子的撞击,以使得能够 气体分子CO 2的解离以从烟道气中去除CO 2; 和c)将从步骤b)获得的烟道气与第三液体介质接触,所述第三液体介质提供包含反应性电子或离子的第三等离子体,其量使得气体分子的NOx经受第二等离子体中的电子或离子的撞击 使得气体分子NOx的解离能够从烟道气中除去NOx。 本发明还涉及一种用于从烟道气中除去气体组分SO x,NO x和CO 2的系统。 本发明的方法和系统显着降低了资本成本,并且需要非常低的能量,与环保的最终产品。 此外,本发明的塔架可以非常紧凑地构造。
