Level measurement for the power generation industry

Ammonia storage

Ammonia is usually stored as a liquid in pressurized vessels and can be a very difficult compound to measure reliably due to its tendency to change between the liquid and vapor states as the pressure and temperature varies. In addition, the surface of the fluid tends to boil as it moves between states and the heavy vapors can affect measurement accuracy. Ammonia is hazardous and an irritant. It will also diffuse through many elastomers and this needs to be considered when selecting measurement technologies and devices.

Ammonia vaporization

Vaporized ammonia is used in catalytic and noncatalytic reduction systems for emissions control in power plants. Ammonia is injected into the flue gas stream and acts as a reducing agent. The EPA mandates the reduction and control of these emissions, and ammonia is a key part of ensuring that a power plant is compliant with EPA regulations. It is also used to enhance precipitator efficiency for particulate control.  To keep the supply of ammonia readily available for usage and avoid spillage or accidents, a robust ammonia storage system with accurate level measurement must be in place.
