Technical principle:
Absorb the HCL gas by heating the HCL solution according to the volatility of the concentrated HCL solution.
Technical description:
Concentrated HCL enters into the desorption column after pre-heating, carry out the mass and temperature transfer by each progress in the column, separate HCL gas (purity≥99%) from the top of column, cool the gas to low temperature and send to the HCL demister without the acid droplets. After all these done, the HCL gas is sent to the following process. Discharge the azeotropic acid, flow back to the diluted HCL tank after cooling the acid to room temperature. The bottom reboiler provides the desorption heat constantly.
Technical characteristics:
1.DCS automatic control, reliable and efficient safe interlock control system.
2.High quality HCL. Delivery pressure: 0.05～0.3MpaG according to requirements.
