Abstract:
A process for reducing the foam formation occurring when a dispersion or a liquid is treated with steam bya) introducing the steam into a lower region of a column and simultaneously feeding the dispersion or the liquid at the top of the column, the steam ascending to the top of the column, and b) contacting the dispersion or the liquid with the steam which results in the formation of the foam, which process comprisesfeeding the dispersion or the liquid to the column in the form of a mixture generated by mixing the dispersion or the liquid with steam in an apparatus to form a dispersion/steam mixture or a liquid/steam mixture, and feeding the mixture into the top of the column in form of a mixture which has a higher temperature than that of the steam which comes into contact with the mixture in step b).
