ABSTRACT:
The instant invention is directed to a method of inhibiting and dispersing deposit formation on metal surfaces of an evaporator used for the processing of black liquor which comprises the step of treating black liquor, at any point prior to completion of said processing, with a deposit inhibiting concentration of low molecular weight cationic polymer selected from the group consisting of poly(diallyldimethylammonium chloride), polymethacrylamidopropyltrimethylammonium chloride, poly-2-methacryloxyethyltrimethylammonium methosulfate, and poly-2-methacryloxyethyltrimethylammonium chloride.
