Abstract:
1. A heat exchange reactor, comprising: at least one tube bundle comprising a plurality of tubes arranged substantially parallel to a common longitudinal axis and within an external pressure housing, said bundle comprising first and second ends in respective first fluid communication with at least one first fluid inlet and at least one first fluid outlet, and said external pressure housing comprising at least one second fluid inlet and at least one second fluid outlet; at least one baffle oriented substantially perpendicular to the longitudinal axis and disposed about said bundle and configured as a manifold to control a flow of said second fluid; and at least one layer of interior thermal cement-bound refractory insulation disposed between said bundle and said housing and in fluid communication with said second fluid, wherein said insulation comprises a load-bearing zone configured to support an average compressive load of at least one pound per square inch and a non-load bearing zone configured to support an average compressive load of less than one pound per square inch, and wherein said insulation is made from a first material in said load-bearing zone and a second material in said non-load bearing zone, and wherein said first material is different from said second material.
