Abstract
A heat and mass transfer assembly is described, which in various implementations may be constituted as a packing element including a plate array including heat transfer plates and mass transfer plates in a modular structure in which the number of heat transfer plates and mass transfer plates may be varied to effect desired levels of heat and mass transfer, and multiple packing elements can be integrated in a heat and mass transfer packing assembly, to carry out a wide variety of fluid contacting processes.
Claims31
A heat and mass transfer assembly for a fluid contacting apparatus, the heat and mass transfer assembly comprising a packing element comprising a plate array including heat transfer plates and mass transfer plates arranged to contact respective fluids on the mass transfer plates, the heat transfer plates including interior heat exchange passages, the packing element further comprising heat exchange fluid flow circuitry connected to the heat transfer plates in the plate array to flow heat exchange fluid through the heat transfer plates in the interior heat exchange passages thereof and to discharge heat exchanged fluid from the heat transfer plates.
