Abstract:
Dialkoxysilane and Monoalkoxysilane functionalized polymers were applied as scale control agents in Bayer process. The polymer inhibitors reduced the quantity of aluminum silicate scale formed in spent liquor while significantly changed the morphology of the scale. Also a method is provided for reducing aluminum silicate scale of Bayer process by adding the dialkoxysilane and monoalkoxysilane functionalized polymer into the Bayer liquor stream.
