New water degassing plant Focus on new plants: Hasseroeder Brauerei GmbH, Wernigerode
The water degassing plant described below has been installed as one option to reduce the negative effects that oxygen has in brewing liquor, with a view to obtaining commercial, technological and qualitative advantages in filtration and filling.
Carbon dioxide (CO2) is used for degassing in the compact column, dispensing with expensive vacuum and multi-stage systems. The high degree of oxygen reduction to a residual oxygen content of less than 0.02 ppm comes about from desorption under atmospheric pressure with gaseous carbon dioxide (CO2).
Function
Mass transfer in the deaeration column is driven by the difference in solubility of oxygen or air and carbon dioxide gas, with contact over a very large reaction surface area. It then flows e.g.....
