Processing Problems

How can enzymes enhance your processes?

Bacterial infections, high viscosity, high acid, low sugar – you know the common problems that can plague an ethanol fuel production plant. Luckily, there are solutions.

Novozymes process enhancement enzymes are proven to help solve many of the common processing issues at ethanol plants. From infection-fighting during fermentation to viscosity reduction during liquefaction, Novozymes solutions can improve your ethanol fuel production process and help you gain success.

High-Viscosity fighting enzymes

Viscosity Villains

High viscosity can cause major hassles in the ethanol fuel production process. Non-starch polysaccharides like beta-glucans and arabinoxylans create high viscosity, which has a negative impact on downstream operations.

High viscosity also limits the dry substance level in the process, increasing energy and water consumption and lowering ethanol yield. Non-starch polysaccharides also reduce the efficiency of separation, evaporation, and heat exchange.

The solution? Enzymes.

Novozymes Viscozyme® enzymes enable higher ethanol fuel production capacity and lower operating costs. This means more choice of cereal and raw material quality together with the ability to process at higher dry substance levels.

Fight infections in biofuel

Bacterial Warriors

High lactic and acetic acid levels that are generated by bacteria during fermentation can cause infections and stress on your yeast. While some might choose antibiotics to fight this, we prefer the natural warriors: enzymes.

Novozymes enzymes can decrease these acid levels and improve your fermentation efficiency by letting your yeast to grow in a less stressful environment. For North American producers, reduced lactic acid levels mean reduced antibiotics use. For others, reduced organic acid levels allow for better fermentation yields.

With Novozymes Viscozyme®, you can produce more renewable energy than previously thought possible. This portfolio of xylanases breaks down the components of grains that would otherwise be too thick. The resulting thinner mash helps enzymes break the material down into sugars for fermentation into ethanol fuel.

Benefits

  • Superior viscosity reduction above 80C
  • Flexible raw material choice of wheat, triticale, barley and rye
  • Higher ethanol fuel output due to more dry matter in the     mash
  • Lower operating costs
  • Flexible temperature use below 80C
  • Customized solutions that optimize your plant design and     operations
