METHOD OF PREVENTION OR REDUCTION OF THE ALUMINOSILICATE SEDIMENTATION IN BUYER'S METHOD Russian patent published in 2007 - IPC C23F14/02

Abstract RU 2311494 C2

FIELD: chemical industry; other industries; methods of prevention or reduction of the sedimentation of the aluminosilicates.

SUBSTANCE: the invention is pertaining to the method of reduction of the sedimentation of the aluminosilicates in Buyer's method. The invention presents the method of reduction of the sedimentation containing aluminosilicate in Buyer's method including the stage: addition in to the stream of Bayer's method of the polymer having the side group, or the end group, the formula I: --Si(OR")₃ Formula I, where R" represents Н, S₁- S₁₀-alkyl, aryl, Na, K or NH₄, in the quantity inhibiting the sedimentation containing aluminosilicate. When the materials of this invention are added into Bayer's liquid before the heat exchanger, they reduce or even completely prevent formation of the sedimentation of the aluminosilicate on walls of the heat exchanger. The given materials are effective at the operational concentrations, that makes them efficient in practice.

EFFECT: the invention ensures, that the given materials are effective at the operational concentrations, that makes them efficient in practice.
