ABSTRACT:
The method of this invention is particularly useful for removing heat from an exothermic reaction of a liquid medium. An example of such a reaction is an emulsion polymerization of styrene and butadiene to obtain a latex product. In this reaction the butadiene will boil at the temperature and pressure conditions in the reactor. Attached to the reactor is a condenser unit, which is basically a modified shell and tube heat exchanger. During the reaction the butadiene vapors are directed from the reactor into the tube bundle of the condenser unit through the top of the unit. In the condenser the butadiene vapors are condensed to a liquid, which flows downwardly into the reactor to cool the reaction mass.
