Nitroglycerine is manufactured by nitration of natural or synthetic glycerine. Nitration is achieved by slowly adding high purity glycol and glycerol to the mixture.
Waste acid treatment has high risk for an explosive reaction. Vaisala K-PATENTS® Process Refractometer PR-43-GP is used to ensure a safe operation by continuously monitoring the nitroglycerine and nitroglycol concentration in the waste.
