|20150203789||PROCESS FOR PURIFICATION OF EPA (EICOSAPENTANOIC ACID) ETHYL ESTER FROM FISH OIL - Disclosed is a process for extracting and purifying EPA (Eicosapentanoic acid) ethyl ester from a crude fish oil feedstock using a combination of novel esterification and simulated moving bed (SMB) techniques. Crude fish oil diluted in non-polar solvent is esterified with an acid and then transesterified with a base. Following washing, the non-polar phase is directly passed to an SMB zone, comprising a normal phase separation with a hydrophilic stationary phase agent and a non-polar/organic polar mobile phase desorbent to provide an enhanced omega-3 product, comprising EPA. In a further embodiment, the enhanced omega-3 product is passed to a second and third SMB zones operating in reverse phase using a hydrophobic stationary phase and a polar mobile phase desorbent. The process is useful for producing high purity EPA at purities in excess of 97 wt-% which are not economically recoverable by conventional distillation methods combined with conventional SMB configurations.||07-23-2015|

The process is useful for providing a continuous route and a simplified processing route to providing pure alpha-tocotrienol as a major product essentially free of other tocotrienols and tocopherols including: beta-tocopherol, gamma-tocotrienol, delta-tocotrienol, gamma-tocopherol, delta-tocopherol, front end and back end carotenoids, and alpha-tocopherol as a by-product from palm oil extract. Alpha-tocotrienol is a form of vitamin E and may be useful as a treatment for preventing stroke or reducing brain and nerve damage following a stroke.||06-26-2014|
|20140039180||MANNOSE PRODUCTION FROM PALM KERNEL MEAL USING SIMULATED MOVING BED SEPARATION - Disclosed is a process for the production of d-mannose from fermented palm oil kernel meal using a continuous SMB separation process. The process is useful for providing a simplified processing route to providing high purity d-mannose. The SMB process and the SMB cycle was operated to provide a high purity mannose stream comprising d-mannose, salts, and color agents, a primary raffinate comprising glucose, other sugars and salts, and a secondary raffinate consisting essentially of the mobile phase desorbent. In the SMB cycle, the secondary raffinate was recycled to the SMB process as the mobile phase desorbent without further desalination. The highly pure mannose stream was further treated to remove color agents and salts prior to subsequent steps of precipitation or crystallization and drying. D-mannose is useful as a food additive, as a sweetener, as a texturizer, as a stabilizer, or as a humectant.||02-06-2014|
|20130317261||SMB PROCESS FOR THE PURIFICATION OF ETHANOL AND BUTANEDIOL WITH INTEGRATED REGENERATION - Disclosed is an improved SMB process incorporating novel regeneration steps for the separation of ethanol associated oxygenates such as butanediol from a dilute mixture of ethanol and associated oxygenates in water in the presence of organic compounds derived from a biofermentation process. Applicant discovered that increasing the number of raffinate streams alone or in combination with a hot regeneration zone within the SMB cycle can significantly reduce the capital and operating costs associated with the incorporation of the SMB process in a complex for the production of ethanol and butanediol from biofermentation effluent. The process is useful for removing water from dilute aqueous mixtures of organic compounds comprising ethanol in dilute concentration in water and produced by fermentation, biomass extraction, biocatalytic and enzymatic processes which are not economically recoverable by conventional distillation methods.||11-28-2013|
