HEX chemical
reactor-heat exchangers provide safer processing, better economics,
and are more energy-efficient than conventional reactors. HEX
Reactors are compact integrated chemical reactor-heat exchangers
that give marked improvements in productivity and substantially
reduce by-product formation when flow patterns, mixing and heat
transfer rates are tailored to the chemical process requirements.
HEX Reactor technology is now proven for single liquid-phase and
two phase processes, and is being extended to multi-phase processes.
In collaboration with Chart Heat Exchangers LP, BHR Group has
developed the Marbond™ diffusion bonded Hex Reactor.

Design
Approach
Process Intensification (PI) is a design philosophy of matching
reactor fluid dynamics to the physico-chemical requirements of
the reaction to achieve high productivity and selectivity.
Byproduct
formation decreases as mixing intensity and rate of heat transfer
increase. As more reaction heat is removed, mixing benefits become
even more pronounced. Trends can be predicted for industrial reactions
by our experimentally validated model.
