Patent number: 9493391Abstract: The present application provides a method for producing an beta-lactone product. The method includes the steps of: reacting an epoxide, a solvent with a carbonylation catalyst and carbon monoxide to produce a reaction stream comprising a beta-lactone then separating a portion of the beta-lactone in the reaction stream from the solvent and carbonylation catalyst to produce: i) a beta-lactone stream with the beta-lactone, and ii) a catalyst recycling stream including the carbonylation catalyst and the high boiling solvent; and adding the catalyst recycling stream to the feed stream.Type: GrantFiled: September 17, 2015Date of Patent: November 15, 2016Assignee: NOVOMER, INC.Inventors: Scott D.

Publication number: 20160102068Abstract: Continuous flow systems and methods produce succinic anhydride by a double carbonylation of ethylene oxide with carbon monoxide and at least one catalyst. In some embodiments, the double carbonylation occurs using a single catalyst. In other embodiments, a first catalyst is used to promote the first carbonylation, and a second catalyst different from the first catalyst is used to promote the second carbonylation. The succinic anhydride is isolated from the product stream by crystallization and the catalyst is recycled to the reaction stream.Type: ApplicationFiled: September 17, 2015Publication date: April 14, 2016Inventors: Scott D.

Publication number: 20140021135Abstract: A process for a purification of water with multiple contaminants including dissolved solids. The process may involve one or more steps of separating oil and water, metals precipitation, dissolved air flotation (DAF), filtration, forward or reverse osmosis and crystallization. An improved DAF unit is described which increases air dissolution to oxidize impurities and improve flotation. Various embodiments of staged osmotic membrane systems are provided to generate an essentially pure water stream and a highly concentrated solute stream. In some embodiments, reverse osmosis and nanofiltration units are employed in a staged manner. In other embodiments, all stages are reverse osmosis units and the osmotic pressure of each stage is adjusted by the provision of a solution on the low pressure side of the reverse osmosis membrane using nanofiltration membranes. Various recycle options are employed to improve the efficiency of the systems.Type: ApplicationFiled: March 27, 2012Publication date: January 23, 2014Applicant: LIBERTY HYDRO, INC.Inventors: John E.
