Abstract: An improved method for recovering a purified polyether polyol comprising the steps of providing an aqueous solution of a polyether polyol containing an alkali metal catalyst residual formed from a transesterification process, contacting the aqueous solution with a stoichiometric excess of magnesium sulfate to form a second aqueous solution, removing water from said second aqueous solution at a temperature above the melt temperature of said polyether polyol to produce a dehydrated slurry containing a molten polyether polyol phase essentially free of residual alkali metal and a precipitated solid phase comprising sulfate and/or sulfite salts of the alkali metal catalyst, magnesium hydroxide, and excess magnesium sulfate and/or sulfide, passing the dehydrated slurry of through a filtration system comprising a filtration press to separate the molten polyether polyol phase from the precipitated solid phase, wherein the filtration press is treated with a filter aid that is essentially free of transition metal oxide content, separating the molten polyether polyol phase substantially free of water, residual alkali metal catalyst and transition metal contaminants from the precipitated solid phase and recovering polyether polyol from the separated polyether polyol phase.

Abstract: The invention relates to methods for enriching monomer content in a cycloalkane oxidation process mixed organic waste stream. In particular, the methods involve combining a biocatalyst with a mixed organic waste stream from a cycloalkane oxidation process, and enzymatically converting dimeric and/or oligomeric components of said waste stream into monomeric components. The methods may enrich the content of diacids, adipic acid, and/or other α,ω-difunctional C6 alkanes in the mixed organic waste stream. Additionally, the treated mixed organic waste streams may have improved burning efficiency.

Abstract: Disclosed are processes and systems for manufacturing polyethylene terephthalate (PET) and pre-polymer. The processes and systems use a variable pressure drop up-flow-pre-polymerizer configuration. The pressure profile in the UFPP can be selected to beneficially change the relative reaction rates of the polymerization and esterification reactions. This design maximizes the esterification carried out in the UFPP, while still producing a pre-polymer with the optimum carboxyl end groups concentration {e.g., about 30 μ equiv./g to 60 μ equiv./g) to maximize finisher productivity. This can result in a reduction of the size and cost of the esterifier required for a given plant throughput.

Abstract: This invention relates to nonwoven fabrics in which the fibers of the fabric are laid down such that a majority of the fibers have a fiber direction making an angle substantially parallel to or within an angle in a range of +/-45° of the machine direction. The invention also relates to a nonwoven fabric bonded web having bonding points in a pattern arranged along an axis perpendicular to the machine direction spaced and more widely apart than the bonding points arranged along an axis parallel to the machine direction. The resulting nonwoven having a very low elongation in the machine direction can be elongated with relatively little force in the cross machine direction.
