When a Southeast biomass power plant needed reliable level measurement of their ammonia bulk storage tank, they turned to Flowline. The plant’s raw exhaust stream contains hazardous pollutants that are safely removed via their scrubber. Liquid ammonia is one of the chemicals injected into the scrubber as part of the process. Highly corrosive and vaporous, ammonia is difficult to measure. A large bullet tank supplies the scrubber with 19% ammonia. There, the operators had problems with a different radar level sensor brand, that would lock up on the stand-pipe fitting connections. For this reason, Flowline suggested the use of our radar sensors that have digital signal processing technology that disregards erroneous reflections. The radar sensor provides continuous level data to the PLC, which monitors the bulk storage tank and controls the scrubber process. Flowline is reliable level measurement. |
