Publication number: 20200040254Abstract: Suspension of proppants in hydraulic fracturing applications can be strongly affected by the cross-sectional shapes and lengths of the fibers present in the wellbore treatment compositions. For instance, it has been observed that crimped cellulose ester fibers with a trilobal cross-section and an optimized length can provide enhanced suspension of proppants in aqueous fracturing fluids. Furthermore, the present invention demonstrates that non-round cellulose ester fibers can provide superior proppant suspension properties relative to polylactic acid fibers with a round cross-section.Type: ApplicationFiled: October 11, 2017Publication date: February 6, 2020Applicant: Eastman Chemical CompanyInventors: Nick Allen Collins, S M Bedarul Islam, Phillip Michael Cook, Koushik Ghosh

Patent number: 10234077Abstract: A system for automatically evacuating liquids from natural gas pipelines. An embodiment may be used for associated drip vessels and other containers and gas wells. The system includes a tank, a compressor, and an electric generator system. The system evacuates liquid from a pipeline by creating a pressure differential between the pipeline and the tank. When adequate pressure differential is achieved, liquids flow into the tank from the pipeline. When liquids are removed, the system shuts down and awaits a run signal. The system is suited for remote locations, due, in part, to the use of an automatic generator capable of providing power to the compressor and to the CPU as necessary. Liquid removal may be determined by measuring tank pressure at time intervals and determining a rate of change of tank pressure for indicating blow through. The system utilizes the same pipeline tap for liquid removal and gas injection.Type: GrantFiled: September 19, 2016Date of Patent: March 19, 2019Inventor: Nick Allen Pilcher

Patent number: 6864376Abstract: The present invention comprises the use of sulfite additives to reduce discoloration of L-ascorbic acid produced from acid or aqueous solutions of 2-keto-L-gulonic acid. In one aspect, the present invention comprises a continuous process for producing L-ascorbic acid from an aqueous solution of 2-keto-L-gulonic acid. The use of sulfite additives reduces product stream color and improves product recovery by binding to high molecular weight reaction by-products. In a continuous process, the reaction stream is separated from residual sulfite and sulfite-bound by-products to produce a product stream enriched in aqueous ascorbic acid for recovery, and an enriched 2-keto-L-gulonic acid stream which is recycled to the reactor. The in situ use of sulfite additives during the reaction increases the overall yield of L-ascorbic acid, with no loss in selectivity of the synthesis.Type: GrantFiled: December 21, 2001Date of Patent: March 8, 2005Assignee: Eastman Chemical CompanyInventors: Steven Thomas Perri, Michael Roy Cushman, Jeffery Earl Grant Powell, Brendan William Boyd, Bhaskar Krishna Arumugam, Nick Allen Collins

Patent number: 6610863Abstract: The present invention provides methods and an apparatus for the manufacture of an L-ascorbic acid product in high yield by direct conversion of an aqueous solution containing 2-keto-L-gulonic acid by contact with an acid catalyst or under thermal self-catalyzed conditions at a conversion level that maximizes the formation of L-ascorbic acid and minimizes decomposition of the L-ascorbic acid thus formed. The separation process for L-ascorbic acid and KLG is operated in such a way that an efficient separation process allows the majority of the KLG to be recycled for further conversion. The product stream from the separation process is then subjected to a recovery step to obtain crystalline L-ascorbic acid product.Type: GrantFiled: December 21, 2001Date of Patent: August 26, 2003Assignee: Eastman Chemical CompanyInventors: Bhaskar Krishna Arumugam, Nick Allen Collins, Transito Lynne Macias, Steven Thomas Perri, Jeffrey Earl Grant Powell, Chester Wayne Sink, Michael Roy Cushman

Patent number: 6518454Abstract: Disclosed is a process wherein a solution of a carboxylic acid in a first solvent and an alcohol are fed to a simulated moving bed reactor (SMBR) containing a solid(s) to produce a first stream comprising a solution of an ester of the carboxylic acid and the alcohol and a second stream comprising the first solvent. The solid(s) present in the SMBR facilitates the esterification reaction and the separation of the first solvent from the carboxylic acid. The process is particularly valuable for the preparation of an alkanol solution of an alkyl 2-keto-L-gulonate ester (AKLG) from an aqueous fermentation broth containing dissolved 2-keto-L-gulonic acid (KLG) by feeding the fermentation broth and an alkanol to a simulated moving bed reactor which contains a solid acidic esterification catalyst to produce a stream comprising an alkanol solution of an ALKG. The alkanol solution of an ALKG may be used directly to convert the ALKG to ascorbic acid (Vitamin C).Type: GrantFiled: October 12, 2001Date of Patent: February 11, 2003Assignee: Eastman Chemical CompanyInventors: Bhaskar Krishna Arumugam, Larry Wayne Blair, Brendan William Boyd, Nick Allen Collins, David Anthony Larkin, Steven Thomas Perri, Chester Wayne Sink
