Patent number: 7829653Abstract: A horizontal trayed reactor operable to facilitate a chemical reaction in a reaction medium flowing therethrough. The reactor can include a plurality of vertically spaced trays disposed within the horizontally elongated vessel shell. The reaction medium can flow in generally opposite directions on vertically adjacent trays so that the reaction medium flows generally back-and-forth through the reactor.Type: GrantFiled: July 12, 2007Date of Patent: November 9, 2010Assignee: Eastman Chemical CompanyInventors: Thomas Lloyd Yount, Bruce Roger DeBruin, Larry Cates Windes, Roy Douglas Flores, Alan Wayne White, Steven Paul Bellner

Patent number: 7213540Abstract: Disclosed is a method for the re-compression of process generated steam to create a higher pressure steam that is useful as a heating medium in other parts of a carboxylic acid production process or, in general utilized in another process. The invention comprises the following basic steps: (a) recovering thermal energy from at least a portion of the high temperature process stream resulting from an aromatic carboxylic acid production process in a first heat transfer zone to produce a low pressure stream; (b) subjecting the low pressure steam to a compression zone to generate an intermediate pressure steam; (c) utilizing the intermediate pressure steam as a heating medium, specifically within other parts of the carboxylic acid process or generally in another process thereby generating steam condensate; and (d) optionally, recycling all or part of the steam condensate to the second heat transfer zone for low pressure steam generation.Type: GrantFiled: February 5, 2004Date of Patent: May 8, 2007Assignee: Eastman Chemical CompanyInventors: Robert Lin, Steven Paul Bellner

Patent number: 6683216Abstract: Disclosed is a process for the preparation of amines by continuously feeding a carboxamide, aqueous alkaline hypohalite, and aqueous alkaline hydroxide to a first reaction zone to form a N-halocarboxamide, measuring the concentration of at least one reaction component in the effluent from the first reaction zone, and using the result of that measurement to control the feed rate of at least one of the feed components of to achieve at least 90% conversion of the carboxamide in the first reaction zone. The effluent from the first reaction zone is fed continuously to a second reaction zone where it further reacts to form an aqueous solution of an amine. The effluent from the second reaction zone may be fed continuously to a distillation column. The process is particularly useful for the preparation of cyclopropylamine.Type: GrantFiled: November 6, 2002Date of Patent: January 27, 2004Assignee: Eastman Chemical CompanyInventors: Joseph Robert Zoeller, Norma Lindsey Buchanan, Elizabeth Celia Sharkey, Daniel Latham Terrill, Steven Paul Bellner

Patent number: 6111036Abstract: Disclosed herein is a fluid bed polymerization process including an improved method for cooling the fluid bed. The recycled fluid stream is cooled by a method comprisinga) cooling said gas sufficiently to condense a portion of said gas to a liquid,b) thereafter separating said liquid from said cooled gas,c) compressing said cooled gas,d) thereafter recooling said cooled gas sufficiently to condense a portion thereof to a liquid,e) reintroducing said liquid portions and said recooled gas into said reactor sufficiently to maintain reactive conditions.Type: GrantFiled: October 16, 1997Date of Patent: August 29, 2000Assignee: Eastman Chemical CompanyInventors: Alan George Wonders, Mark Alan Edmund, Anthony Dominick Messina, Steven Paul Bellner, Randal Ray Ford
