蒽醌 process production
H2O2 aqueous solution is a colorless transparent low-viscosity liquid. At present, most of the process is prepared by using a hydrazine process, which is a working solution of alkyl hydrazine and an organic solvent. The pressure is 0.30 MPa, the temperature is 55-65 ° C, and a catalyst exists. Under the conditions, hydrogen is hydrogenated, and then subjected to countercurrent oxidation with air (or oxygen) at 40-44 ° C, and extracted, regenerated, refined and concentrated to obtain a hydrogen peroxide aqueous solution having a mass fraction of 20% to 30%. .
ATAG0 (Atago) line concentration instrument, by way of pipe installation, the installation in an extraction column and distillation column outlet line detection by H2O2 aqueous solution concentration, and the concentration to remote DCS, to help improve the extraction efficiency and control the concentration of the finished product.
The ATAGO online concentration meter can measure full scale 0-100%. Due to the production environment requirements, the probe needs to be intrinsically safe.
ATAGO online concentration meter CM-800a pipe adapter has its own high-pressure water flushing pipeline to ensure that the measurement results will not be affected by the high-viscosity adhesion instrument prism during the production process.
In order to be able to measure various types of aqueous solution concentrations (dilution) simultaneously by Brix values, the ATAGO refractometer is capable of directly displaying the concentration value on the screen. There are over 80 special scales to choose from.
