NITRATE CHALK PULP ANALYZER Russian patent published in 2019 - IPC G01N31/00 G01N21/01 

FIELD: chemical or physical processes.

SUBSTANCE: invention relates to controlling amount of carbon dioxide in a conversion reactor in a process for producing chalk and conversion solutions of ammonium nitrate, which affects the quality and yield of chalk production. Nitrate chalk pulp analyzer includes a sampler for sampling filtered nitrate chalk pulp to be analyzed, a reaction chamber made in the form of a coil of transparent material, connected to a sample analysis unit comprising an infrared phase separation sensor, intended for measuring concentration of carbon dioxide formed in reaction chamber and connected to processing unit, pipeline lines with inlet and outlet fittings for connection of air to analyzer cabinet, for supply and discharge of sample, acid and flushing fluid, connected with peristaltic pumps, connected to pump control unit to control volume of supplied sample and volume of supplied acid to reaction chamber, at that pipeline lines contain valves, tees, connectors.

EFFECT: possibility of continuous monitoring of content of excess carbon dioxide in a conversion reactor, which increases reliability of operation of a conversion plant.
