A developer and producer of generic drugs uses a pharmaceutical process that involves coating products with a mixture of solvents and then heating them in batch ovens. The solvents evaporate off, are collected and fed into a main duct, that feeds into the thermal oxidizer for destruction.
A specialty chemical manufacturer of pure resins collects & sends the discharge from the manufacturing process to a wastewater collection pit.
They continuously monitored the atmosphere of the collection pit with LFL infrared sensors for parts per million levels, confirming safe release of the wastewater. However, they found the IR sensor's scale was too high to detect the low ppm levels they needed.
