Technical principle:
Desorb concentrated HCL or diluted HCL deeply by adding breaking-azeotropic agent.
Technical description:
Carry out the mass and temperature transfer in the desorption column after mixing HCL and breaking-azeotropic agent. Desorb the HCL after breaking the azeotropic agent. Send to the following process after drying.
Evaporate and concentrate the azeotropic agent solution after desorbing HCL, recycle to desorption column for HCL desorption, which makes a constant system.
Technical characteristics:
1.DCS automatic control, reliable and efficient safe interlock control system.
2.High quality HCL gas.
3.Delivery pressure of HCL: 0.05～0.3MpaG according to requirements.
