Odor Control Agents

The need for Odor Control agents in Pulp mills

Many of these released gases emitted unpleasant odors. The odorous substances can also affect product quality and may result in complaints and reduced revenue. Odor emissions may lead to grievances from neighbors, complaints from authorities and even call the industrial location into question. Occupational safety may even be endangered in some extreme cases.

Identifying causes of odors and implementing correctiveaction is paramount for the survival of the industry while maintaining efficient production process.
