摘要： The gaseous effluent to be treated is contacted in C1 with an absorbent solution selected for its property of forming two separable phases when it has absorbed an amount of acid compounds and when it is heated. The absorbent solution laden with acid compounds is then heated in E1 and E3 so as to separate two fractions in BS1: a first absorbent solution fraction depleted in acid compounds and a second absorbent solution fraction enriched in acid compounds. The second fraction is regenerated in C2 so as to release part of the acid compounds, and the first absorbent solution fraction and the regenerated absorbent solution are recycled as absorbent solution.According to the invention, an absorbent solution portion circulating in C1 is cooled in E2 in order to prevent demixing of the solution in column C1.
摘要翻译：待处理的气态流出物在C1中与吸收剂溶液接触，吸收剂溶液当其吸收一定量的酸化合物时和加热时形成两个可分离相的性质。然后将含酸化合物的吸收剂溶液在E1和E3中加热，以分离BS1中的两个级分：消耗酸性化合物的第一种吸收剂溶液级分和富含酸性化合物的第二种吸收剂溶液级分。第二部分在C2中再生以释放部分酸化合物，第一吸收剂部分和再生吸收剂溶液作为吸收剂溶液再循环。根据本发明，在C1中循环的吸收剂溶液部分在E2中冷却，以防止溶液在柱C1中分层。

摘要： The invention is a method of formation and a structured packing for a fluid exchange column, which defines an exchange surface for at least one descending liquid phase to be placed in intimate contact with at least one ascending gaseous phase. The packing comprises a stack of plates having undulations, each plate being contained in a space included between two parallel planes L1 and L2 separated by a value of between 5 and 50 mm. The undulations are distributed on both sides of a center plane P separating the space into two equal parts and form a series of channels which extend along a direction D. The channels comprise wings contained in the space included between the two parallel planes. Each wing is composed of a strip B punched out in one of the channels according to at least two grooves C1 and C2. The width of the strip between the two grooves is between 1 and 15 mm. The strip B is stamped/embossed to create an orifice forming a discontinuity in the surface of the channel at the level of the two grooves C1 and C2.
