Abstract
Hydrophobically modified Si-containing polyamines are useful for treating scale in industrial process streams. Preferred hydrophobically modified Si-containing polyamines are particularly useful for treating aluminosilicate scale in difficult-to-treat industrial process streams, such as in the Bayer alumina process streams, nuclear waste streams and kraft paper mill effluent streams.
