Difficulties for persistent control of foam in pulp operations

Pulp and paper makers need to reduce excessive foam created in the pulping process, when extracting cellulose fibers from wood, and during the washing process when making products such as Kraft brown-stock. Also due to various contaminants, foam is a permanent trouble during recycling operations. To process, manufacturers use foam control formulations, ‘antifoams’ or ‘defoamers’. To be competitive, pulp manufacturers are constantly seeking to lower costs and to use less water, energy and chemicals. Also to minimize their impact on the environment.

In all these respects, silicone-based antifoam formulations outperform mineral-based products, being easier to use – and at lower dosage – to produce better quality pulp. Silicones provide both greater and more rapid knockdown, and more persistent control of foam, and are stable across the extreme pH and temperature conditions needed to make pulp.
