Abstract: A process, a system, and an apparatus for separation of an oxygenate from a stream is provided. More specifically, a stream comprising the oxygenate is introduced to a quench tower along with a caustic outlet stream comprising a metal salt. Contact between the oxygenate and the metal salt results in conversion of a portion of the oxygenate into a derivative salt. The derivative salt and unconverted oxygenate are condensed by quenching and substantially removed from the quench tower as an oxygenate outlet stream. The gaseous components of the stream, minus a substantial portion of the oxygenate, are removed from the quench tower as a quench outlet stream.

Abstract: Barrier films are prepared from a composition comprising 1) a blend of two high density polyethylene HDPE blend components, 2) zinc glycerolate and 3) a dispersion aid/synergist. The two high density polyethylene blend components have substantially different melt indices. It is difficult to properly mix the zinc glycerolate into this HDPE blend. The use of the dispersion aid/synergist improves the water vapor transmission rate (WVTR) of polyethylene film (in comparison to barrier films made with zinc glycerolate, in the absence of the dispersion aid/synergist). The resulting barrier films are suitable for the preparation of packaging for dry foods such as crackers and breakfast cereals.
