"The customers we've worked with in developing this value-added product have documented a number of benefits from using the PTV M-5309 corn oil extraction aid," said McCord Pankonen, global biorefining marketing manager, water technologies.
"The real beauty of the product is that refiners don't have to change their process."
The patent-pending extraction aid is chemical rather than mechanical and therefore, requires no additional capital expenditure, Pankonen
It is added to the process after distillation, to the syrup being separated into corn oil and DDGs and works by improving the release of oil during mechanical extraction.
The resulting oil contains less solids and means a reduction of system deposits, adding up to less downtime for cleaning and maintenance.
The company began testing its extraction aid in 2009 in ethanol facilities.
Because all plants are not alike, it has worked with more than 20 ethanol plants to confirm and quantify the results of using the chemical extraction aid.
"We worked very closely with our customers to design a technology that is easily integrated into their existing process," Pankonen
The company's work with ethanol producers in the past has focused on providing water treatment chemicals to control corrosion, reducing microbial contamination and helping to install zero-discharge water reuse systems.
In working to help customers enhance their bottom line, the Ashland biorefining team recognized the opportunity for a corn oil extraction aid, Pankonen
