  • Page 10: Product Description

    AMI Hydrazine Product Description Product Description 2.1. Description of the System Microprocessor controlled system for the determination and control of hydrazine or carbohydrazide used as boiler feedwater oxygen scavengers. Application Hydrazine is used in power plants as an oxygen scavenger. It helps to remove oxygen, which may cause corrosion in the power plant.
  • Page 11 Temperature compensation is done automatically. Fluidics The measurement of hydrazine requires a high pH of the sample. The AMI Hydrazine buffers the pH to pH>10.5 by adding diisopro- pylamine. The diisopropylamine is dissolved in the water while flowing through a diffusion tube.
