POLYAMINE SCALE INHIBITOR COMPOSITIONS, AND METHODS OF TREATING SCALE IN PROCESS STREAMS

摘要

PROBLEM TO BE SOLVED: To provide additive compositions useful for treating aluminosilicate scale included in industrial process streams, such as the Bayer alumina process streams, nuclear waste streams and kraft paper mill effluent streams.SOLUTION: The compositions contain a polymeric reaction product of a polyamine and nitrogen-reactive compounds, e.g., a polymeric reaction product of polyethyleneimine, glycidoxypropyl trimethoxysilane and chlorooctane.
