ABSTRACT:
A divided wall exchange column includes a dividing wall strengthened by stiffening members and/or a double wall design to better withstand pressure differentials and minimize temperature differentials. When a double wall is used, cost of manufacture and installation is minimized by reducing the manufacturing tolerances required while providing a design robust in construction, installation, and operation. When structured packing is used, the stiffening members, combined with positioning the layers of packing at preferred angles relative to the dividing wall, result in minimal interference with the heat and/or mass transfer process while minimizing the complexity of manufacture and construction of the packing. Further, by positioning the top layer of structured packing at other preferred angles relative to the dividing wall, a simplified liquid distributor design may be used in the divided wall exchange column while the layers below may still be orientated as described above with all the associated benefits.
