Abstract:
(EN) Provided are a process and a device for purification of tail gas containing volatile organics. Tail gas to be treated is brought into a sectional absorption tower (T101, T111, T121) from the bottom of the tower, and the volatile organics are removed from the tail gas by absorption with a solvent; and the tail gas continues to rise, and the solvent volatile and/or entrained in tail gas is removed by absorption with water to obtain purified tail gas. The device comprises a sectional absorption tower (T101, T111, T121) comprising a water absorption section located at the upper part inside the tower (T101, T111, T121) and a solvent absorption section located below the water absorption section.
(FR) L'invention concerne un procédé et un dispositif de purification de gaz de queue contenant des matières organiques volatiles. Le gaz de queue à traiter est amené dans une tour d'absorption à sections (T101, T111, T121) depuis le fond de la tour, et les composés organiques volatiles sont éliminés du gaz de queue par absorption avec un solvant; et le gaz de queue continue à s'élever, et le solvant volatile et/ou entraîné dans le gaz de queue est éliminé par absorption avec de l'eau pour obtenir un gaz de queue purifié. Le dispositif comprend une tour d'absorption à sections (T101, T111, T121) comprenant une section d'absorption d'eau située au niveau de la partie supérieure à l'intérieur de la tour (T101, T111, T121) et une section d'absorption de solvant située au-dessous de la section d'absorption d'eau.
(ZH) 一种含挥发性有机物尾气的净化工艺及设备,将待处理尾气从塔底进入分段式吸收塔(T101、T111、T121)内,尾气经溶剂吸收脱除挥发性有机物;尾气继续上升经水吸收脱除挥发的和/或尾气中夹带的溶剂,得到净化尾气;该设备包括分段式吸收塔(T101、T111、T121),该吸收塔(T101、T111、T121)包括位于塔内上方的水吸收段和位于水吸收段下方的溶剂吸收段。
