摘要:
A process for the drying of water-containing materials which are suitable for use as wetting agents, detergents or cleaning products. An aqueous solution, emulsion or suspension of the materials is dried using superheated steam as the drying gas wherein the drying gas is recycled to the drying zone after removal therefrom of evaporated water and the energy required for the evaporation of water is supplied to the superheated steam by heat exchangers.
