Solenis introduced a new scale inhibitor for ethanol plant evaporators at the 2015 Fuel Ethanol Workshop & Expo (FEW) in Minneapolis last week.
Solenis, a leading global producer of specialty chemicals, launched the Polystabil™ AS4535 scale inhibitor specifically designed to help fuel ethanol producers control scale in their evaporators, improving heat transfer and reducing downtime while still meeting regulatory guidelines for chemical usage.
“Today’s fuel ethanol processes tend to generate more scale than ever before,” said Allen Ziegler, global biorefining marketing director. “This novel product performs significantly better than polyacrylate chemistries and allows fuel ethanol plants to split feed the chemistry, for example at the front of the evaporators to treat the whole system, and then with an additional dosage before problem areas, such as the evaporator where inorganics are concentrated. This results in improved heat transfer efficiency and a reduced need for cleaning and related downtime. Fuel ethanol operations using Polystabil AS4535 scale inhibitor are therefore able to maintain maximum efficiency while staying within regulatory limits.”
The new scale inhibitor represents one of many solutions recently developed for fuel ethanol producers by Solenis, which was previously known as Ashland Water Technologies. Other process and water treatment innovations include FDA-approved corn oil extraction aids for both disk-stack and tricanter systems; a proprietary control system that allows for around-the-clock surveillance and control of process and water treatment programs; a low-corrosion microbiocide for cooling water systems; and new antibiotic-free fermentation aids.
