A highly efficient and effective process for destroying organic contaminants in wastewater streams, without the need for supercritical oxidation conditions, is provided.

Process and system for subcritical oxidation of water-borne organic contaminants

Aspects of the present invention relate to systems and processes for obtaining desired mercaptans or thiophenes from a feed stream containing a mixture of mercaptans, thiophenes and other components. In one aspect of the invention, a system for separating one or more components from a feed stream of mixed mercaptans includes one or more distillation columns in connection with a feed containing mercaptans, the distillation column having a rectification section, a stripping section, and a feed side section separated from a side draw section by a dividing wall that extends from the rectification section to the stripping section. The distillation column further being in connection with a condenser and a reboiler; and a distillate stream, a side drawn stream, and a bottoms stream.

A process for producing an alkanolamine includes supplying a reactive distillation apparatus having an inner contacting surface which simultaneously facilitates a reaction process and a distillation process, feeding a first reactant including an amine represented by R'NH, wherein R&#x2032; is a hydrocarbon group, and X is 1, 2, or 3, feeding a second reactant including an akylene oxide represented by R&#x2033;O, wherein R&#x2033; is a C-C-alkylene, feeding a catalyst in an amount from 0% to about 15% by weight of a mixture of the first reactant, the second reactant and the catalyst; recycling an overhead output from an overhead portion including an unreacted portion of the amine and the catalyst to achieve a substantially total reflux of the amine and the catalyst, and collecting a product output including an alkanolamine, the alkanolamine being a member selected from the group consisting of a monoalkanolamine, a dialkanolamine, and a trialkanolamine.
