Реферат: A spray tower reactor comprises: (a) a spray tower; (b) a refrigerator; (c) a gas feed system; (d) a fan; and (e) a collecting container for solids and/or a piping system. A reactor comprises: (a) a spray tower (10) with a spray device (12) in the upper part connected to a feed container (16); (b) a refrigerator (30) with an evaporator (32), condenser (34) and condensed water run-off (40); (c) a gas feed system with its inlet end connected to the upper region of tower (10) and its branched outlet connected not only to the tower upper end but also to the lower end of tower, such that the gas in the closed system is led over the evaporator (32) and condenser (34); (d) a fan (42) redirecting the gas into the circuit; and (e) either a collecting container (22) in the lower region of the tower for solids and/or reaction products or a piping system for leading off the reaction products. An Independent claim is also included for drying of liquids (preferably organic) by: (i) spraying the liquid into a countercurrent of a dry gas (especially air) to evaporate it; (ii) collecting the solids and/or reaction products of the liquid in the lower region of the spray tower; (iii) drawing off moist gas from the upper region of the tower and heat-exchanging it with an evaporator of a refrigerator to collect condensed liquid at the evaporator; (iv) heating the cooled dry gas by contact with the condenser of the refrigerator; and (v) recycling the heated dry gas to step (i).
