`New Additive Increases Corn Oil Yield and Provides Cleaner
`Oil in Disk-stack System
`Ashland™ PTV M-5309 corn oil extraction aid
`
`Customer Overview:
`• Segment: Biorefining
`• Products: Fuel ethanol, DDGS, wet cake, syrup
`and corn oil
`• The corn oil is sold to the biodiesel industry and
`the other products are sold as animal feed
`• Location: Midwest United States
`
`Application Overview:
`• System: A Disk-stack centrifuge used for corn oil
`extraction
`• Capacity: 50 MM gallons of fuel ethanol per year
`• Oil processing unit typically treats 45 gpm of syrup
`• Syrup solids are typically 28%
`
`Existing Treatment:
`• No full-time treatment was used.
`
`Problem Summary:
`After installing a corn oil extraction system at
`significant capital expense, the plant's anticipated corn
`oil yield was not achieved. As the return on investment
`was not being realized, plant management recognized
`the potential of the PTV M-5309 extraction aid to
`increase corn oil production and improve the return on
`capital.
`
`Customer Objectives:
`Increase corn oil yield
`•
`• Maintain corn oil quality (solids and moisture)
`• Meet feed quality specifications (Profat Tag)
`
`Ashland Solution:
`With a long history in developing chemical innovations
`for process improvement, Ashland Water
`Technologies developed a new product that increases
`corn oil yield and improves corn oil quality in plants
`producing 50 to 100 million gallons of
`
`fuel ethanol per year. The product, which is marketed
`as Ashland PTV M-5309 corn oil extraction aid, works
`under a wide variety of operating conditions and can
`be used with both Disk-stack and Tricanter
`centrifuges.
`
`Ashland's corn oil extraction aid contains no APEs or
`VOCs and is biodegradable, kosher certified and
`generally recognized as safe (GRAS). Additionally,
`Ashland has a pending patent application for use of
`PTV M-5309 in corn oil extraction.
`
`Ashland technical and sales specialists reviewed the
`customer's corn oil production process and
`recommended the new extraction aid. During
`the plant audit, feed points were identified. Due to the
`extreme variability in oil production, an extended trial
`of the extraction aid was approved by plant
`management.
`
`During the trial, the feed rate for the extraction aid was
`adjusted to provide maximum corn oil production. In
`addition, profit contributions were calculated and
`confirmed by the plant on a daily basis.
`
`Customer Benefits:
`• Corn oil yield was increased by 500,000 gallons
`per year, which increased profits more than $1
`million per year
`• Corn oil quality (solids and moisture) was
`improved
`• Feed quality specifications (Profat Tag) were met
