Abstract: A liquid slurry of bentonite which comprises bentonite, water, a polyacrylate, and a sodium salt of silicic acid. Optionally, a sulfonate is present in an amount of between about 10 to about 30% by weight.

Abstract: A process for preparing a liquid slurry of bentonite which comprises the steps of charging a reactor vessel with between about 25 to about 75% of water by weight. The water is heated to a temperature range between about 50.degree. C. to about 95.degree. C. The reactor vessel is charged with between about 0, 1 and about 10% of sodium salt of silicic acid by weight and with between about 15 to about 35% of bentonite by weight. The reactor vessel is also charged with between about 10 to about 30% of a polyacrylate by weight.

Abstract: A flocculating agent which comprises: a particulate polyethylene oxide; an inert liquid vehicle comprising a mixture of a glycol and glycerine, wherein the specific gravity of the polyethylene oxide is approximately the same as the specific gravity of the inert liquid vehicle; a suspension agent, and, optionally, an acidic compound.

Abstract: In a process for the separation of hydrocarbon materials and other materials including ammonia and hydrogen chloride normally associated with the hydrocarbon materials in refining of petroleum, the deposition of ammonium chloride is retarded or prevented by introducing inert gas of higher volatility into the processing operation upstream from where the deposition of ammonium chloride would otherwise occur.

Abstract: A flocculating agent which comprises: a particulate ethylene oxide polymer present in an amount of between about 20 to about 35% by weight; an inert liquid vehicle comprising a mixture of a glycol which is present in an amount between about 25 to about 30% by weight, and glycerine which is present in an amount between about 45 to about 50% by weight, wherein the specific gravity of the ethylene oxide polymer is approximately the same as the specific gravity of the inert liquid vehicle; and a suspension agent which is present in an amount between about 0.4 to about 0.6% by weight, wherein the flocculating agent has a viscosity in the range between about 1800 to about 5900 cps.

Abstract: A method of treating BCTMP/CTMP wastewater to improve retention and purification of cellulose fiber suspension and clarification of the BCTMP/CTMP wastewater which comprises the addition of a cationic, water soluble coagulant having a molecular weight less than 15,000,000 in an amount of about 1 to about 300 ppm; and a high molecular weight flocculant selected from the group consisting of: nonionic polymers having a molecular weight in the range between about 500,000 to about 30,000,000, low charge cationic polymers having a molecular weight in the range between about 5,000,000 to about 30,000,000, and low charge anionic polymers having a molecular weight in the range between about 5,000,000 to about 30,000,000, in an amount of about 0.1 to about 100 ppm.
