Abstract: Disclosed herein is a fouling-resistant system for the manufacture of a compound by distillation, the system including a reactant heating zone; a distillation column in fluid communication with the reactant heating zone wherein the distillation column comprises a plurality of distillation trays for removing by-products from the reactants, and wherein at least 20% of the plurality of distillation trays are baffle trays arranged in a staggered configuration; where each tray contacts an opposing portion of an inner wall of the distillation column from a portion contacted by a tray located above the tray and below the tray; and wherein the baffle trays are disposed in a lower portion of the distillation column.

Abstract: A process for increasing the service life of a solar receiver by reducing the concentration of dissolved hydrogen present in a hydrogen atom containing liquid (HACL) stream including (a) contacting a HACL stream containing a first concentration of dissolved hydrogen with an inert gas stream under predetermined process conditions such that at least a portion of hydrogen in the HACL stream is transferred to the inert gas stream and a second reduced concentration of dissolved hydrogen remains in the HACL stream; and (b) passing the HACL stream having the second reduced concentration of dissolved hydrogen through the solar receiver.

Abstract: A process for converting tertiary halogenated hydrocarbons in a tertiary halogenated hydrocarbon-containing stream to a corresponding unhalogenated or less-halogenated unsaturated hydrocarbon product with the release of hydrogen halide involves contacting the tertiary halogenated hydrocarbon with a sorbent-type dehydrohalogenation catalyst in a reaction zone and optionally passing a stripping gas through the reaction zone to remove vapor phase reaction products from the reaction zone.
