Hello, good time I want to convert 30% hydrochloric acid in industrial dimensions to 37% concentration in laboratory grade I wanted to see how I can get the process description and thermodynamic data extraction and process map Thank you for helping me
One way may be to absorb hydrogen chloride gas into 30% HCL in a packed bed absorber column under slight pressure, since HCL gas is quite soluble in water. See Fig 2-11 for enthalpy - concentration data and table 2-10 for vapor pressure of HCl vapor over HCL solutions in the 7th edn of Perry Chem Engg Handbook. With some effort, if you are a chemical engineer, you can work up dimensions for this packed bed.
