Patent number: 8309677Abstract: A system for processing large quantities of a reaction medium while maintaining the reaction medium in sheets. The system includes a reactor having a plurality of vertically-spaced downwardly-sloped trays over which the reaction medium flows while it is subjected to reaction conditions. The slope of the trays increases downwardly to accommodate for the increased viscosity of the reaction medium while the reaction medium flows downwardly through the reactor. An upper portion of the trays have a uni-directional configuration, while a lower portion of the trays have a bi-directional configuration. Further, the orientation of flow across the uni-directional trays is rotated by 90 degrees in at least one location as the reaction medium flows down the uni-directional trays.Type: GrantFiled: January 14, 2010Date of Patent: November 13, 2012Assignee: Eastman Chemical CompanyInventors: Thomas Lloyd Yount, Larry Cate Windes, Bruce Roger DeBruin

Patent number: 7872089Abstract: The disclosure describes a reactor operable to facilitate a chemical reaction in a reaction medium flowing therethrough. The reactor can include a horizontally elongated reactor segment containing a horizontally elongated tubular member and a tray disposed within the tubular member. The reaction medium can flow through the reactor segment on the tray and on the bottom of the tubular member in generally opposite directions. The reactor also can include a header and multiple horizontally elongated reactor segments coupled to the header and spaced vertically apart from one another. The reactor can be used to produce polyesters.Type: GrantFiled: July 12, 2007Date of Patent: January 18, 2011Assignee: Eastman Chemical CompanyInventors: Bruce Roger DeBruin, Michael Paul Ekart, Thomas Lloyd Yount, Larry Cates Windes, David Allen Sliger

Patent number: 7868130Abstract: A multi-level tubular reactor operable to facilitate a chemical reaction in a reaction medium flowing therethrough. The tubular reactor can include a plurality of horizontally elongated and vertically spaced reactor segments coupled to and extending outwardly from a common header. One or more of the reactor segments can contain a tray that divides the internal volume of the reactor segment into upper and lower chambers. The reaction medium can flow away from the header in the upper chambers and back to the header in the lower chambers.Type: GrantFiled: July 12, 2007Date of Patent: January 11, 2011Assignee: Eastman Chemical CompanyInventors: Thomas Lloyd Yount, Bruce Roger DeBruin, Michael Paul Ekart, Larry Cates Windes, David Allen Sliger

Patent number: 7622085Abstract: The present invention provides an assembly for use in vertical, gravity flow driven polymerization reactors for combinations of high viscosity, high throughput, and shallow polymer depths. The baffle assembly module of the invention includes a support structure having a plurality of side openings. The side openings allow the escape of vapor liberated from the polymeric melt. The assembly further includes a feed splitter followed by two or more vertically arranged rows of baffle plates with the feed splitter and baffles sequentially positioned in the support structure. The plurality of parallel baffles in a row are angled such that when a polymeric melt contacts a given baffle the polymeric melt moves in a downward direction under the force of gravity. The arrangement of the rows is such that each row (except the lowest row) transfers the polymeric melt to a lower vertically adjacent row until reaching the last row of baffles in the module.Type: GrantFiled: August 29, 2008Date of Patent: November 24, 2009Assignee: Eastman Chemical CompanyInventors: Thomas Lloyd Yount, Paul Keith Scherrer, Larry C Windes
