Title: Method and instrument for measuring calcium carbonate concentration in slurry
Inventor: YOSHIKAWA HIROBUMI
IPC: G01N31/00
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To measure the CaCO3 concentration in slurry containing CaCO3 in a short time by measuring the dissolved-CO2 concentration of the slurry after adding an acid, such as the hydrochloric acid, etc., to the slurry. SOLUTION: It is preferably to measure the dissolved-CO2 concentration in slurry by lowering the temperature of the slurry, diluting the slurry with water, adding an acid to the slurry under pressure, or stirring the slurry after adding the acid. For this measurement, a system composed of a cooler, an acid adding tank, a stirring tank, and a dissolved-CO2 concentration measurement tank which are arranged in this order from the upstream side to the downstream side along the flow passage of the slurry can be used. For example, the slurry A is sent to the cooler 2 from a line 1 and, after cooling the slurry to a prescribed temperature, the slurry is sent to the acid adding tank 4. In the tank 4, hydrochloric acid B is added to the slurry from an acid adding line 5 and the slurry is stirred up with a line mixer 7. Then the slurry is sent to the measurement tank 8.  In the tank 8, the dissoved-CO2 concentration and pH of the slurry are respectively measured with a dissoved-CO2 meter 10 and a pH meter 10 and, after measurement, the slurry is discharged from a line 11. Therefore, the CaCO3 concentration in the slurry can be measured in a short time.
