A Strong, High-Performing Organic Acid
Using Glyclean™ AN in the purification of acrylonitrile or acetonitrile reduces HCN polymer formation, improves waste management, and boosts product quality. This nonflammable, low-odor polymerization inhibitor is very low in volatile organic compounds (VOCs) and provides proven technology for superior purification of acrylonitrile and acetonitrile. In-depth laboratory testing and field application clearly demonstrates glycolic acid’s superiority over acetic acid.
Features and Benefits
Glyclean™ AN offers a wide range of benefits for acrylonitrile purification operations. With similar handling characteristics to acetic acid, converting to Glyclean™ AN requires minimal effort and offers significant benefits.
Glyclean™ AN allows for a lower total acid consumption, which may improve biological waste treatment options and reduce costs. Because a stronger bond with ammonia reduces the formation of HCN polymer during the purification process, ammonia is unavailable to trigger HCN polymerization reaction. A higher partition coefficient pulls more ammonia glycolate into the water phase, leading to less polymer formation.
With less fouling, anticipated operational improvements include:
- Longer up-time for columns and re-boilers
- Reduced maintenance, repair time, and expenses
- Lower cleaning and disposal costs
