ABSTRACT:
A reactor arrangement and process for indirectly contacting a reactant stream with a heat exchange stream uses an arrangement of heat exchange plates to control temperature conditions by varying the heat transfer factor in different portions of a continuous channel defined by the heat exchange plates. The reactor arrangement and process of this invention may be used to operate a reactor under isothermal or other controlled temperature conditions. The variation in the heat transfer factor within a single heat exchange section is highly useful in maintaining a desired temperature profile in an arrangement having a cross-flow of heat exchange medium relative to reactants. The corrugations arrangement eliminates or minimizes the typical step-wise approach to isothermal conditions.
