Abstract: Countercurrent stripping pipe for removing volatile organic constituents from reaction products, having a column pipe ( 201 ) composed of a plurality of pipe sections ( 201 a-d), in which trays ( 202 ) are arranged, connections ( 205, 208 ) for supplying and removing the reaction products and connections ( 206, 207 ) for supplying and removing at least one stripping agent in countercurrent to the reaction products. In accordance with the invention, a plurality of successive trays ( 202 ) in each case are joined to one another and form at least two inserts ( 211 a-c) which can be removed from the column pipe ( 201 ).

Abstract: Empleo de un tubo de stripping con funcionamiento en contracorriente, con un tubo (101; 201) de la columna compuesto por varios segmentos (101a-c; 201a-d) del tubo unidos entre sí mediante bridas, en el que están dispuestos platos (102; 202) perforados, de modo que en cada caso están unidos entre sí varios platos (102; 202) perforados sucesivos y forman al menos dos piezas (111a-c; 211a-d) insertadas que pueden extraerse del tubo (101; 201) de la columna, conexiones (105, 108; 205, 208) para alimentar y evacuar los productos de reacción y conexiones (106, 107; 206, 207) para alimentar al menos un medio de stripping en contracorriente a los productos de reacción y evacuarlo de éstos para separar los componentes orgánicos volátiles de los productos de reacción poliméricos.
