A process for contacting two counterflowing immiscible liquid phases in a column in which perforated plates define mixing zones and separating zones and in which each mixing zone receives a heavy-liquid phase entering through perforations from above and a light-liquid phase entering through perforations from below and a dispersion formed by the two liquid phases in each mixing zone is transferred from the latter into a juxtaposed separating zone from which the heavy-liquid phase is withdrawn downwardly through perforations and the light-liquid phase is withdrawn upwardly through perforations. The dispersion is contacted in the separating zones with a filling of a material which accelerates coalescence.

Hydrogen containing gases are purified to remove components therein having polymerization, resinification or coking tendencies or to transform such compounds into harmless compounds. The sulfur content of the hydrogen containing gas is adjusted by adding sulfur or sulfur compounds such that the sulfur content is at least 0.05 to 8 g/Nm.sup.3. The adjusted gas is then passed through a hydrogenation catalyst at temperatures between 100.degree. and 400.degree.C. Suitable hydrogenation catalysts are one or more sulfides and/or oxides of metals of the 6th and 8th Group of the periodic system.
