Abstract

A reaction apparatus for corrosive material includes a heat exchanger that is coupled to a header. A first inlet is provided for fluid raw material and a second inlet is provided for introducing a non-corrosive material. There is also an outlet for reaction products. A tube baffle is positioned across the interior of the heat exchanger in order to define an inner space therein and an inner member which substantially conforms to the configuration of the inner space is positioned therein in closely spaced relationship with the inside surface of the header. A first plurality of tubes are attached to opening formed in the baffle and a second plurality of tubes are attached to the inner member and are positioned correspondingly to the first tubes in spaced relation thereto and in fluid communication therewith.
