Abstract: Certain wastewater streams coming out of boilers have temperatures higher than 180.degree. Fahrenheit. Organoclay granules where a quaternary amine acts as a binder will dissolve at that temperature. A cementitious binder is used to pelletice an organoclay made of sepiolite to overcome this problem.

Abstract: A substantially dry method for making organophilic clays. Smectite clays, having a moisture content of less than 12% by weight are sprayed with an activator substance comprising about 1-10% by weight of the clay of a hydrophobic radical including those obtained from an "onium" base selected from a class consisting of ammonium, oxonium, sulfonium, arsonium, stibonium and telluronium. Organic amines and ammonium salts are preferred sources for the hydrophobic radical, and a substituted, hydrogenated tallow ammonium chloride is particularly preferred. The pretreated clay is then subjected to mechanical working such as by compaction to activate the clay.The subject method avoids the addition of water or other solvent to the clay when adding the activator substance, and therefore avoids the added cost of later removing the water, or other solvent. The physical properties of the dry processed organophilic clay are superior in some respects to organophilic clays made by the prior art methods.The organophilic clay made by the subject method can be used for gelling oils and oil-muds to suspend solids in a fluid when the fluid is static. It can also be used to impart cuttings-carrying ability to oil well drilling muds.

Abstract: A method for improving the physical properties of a platey-type clay, which comprises first adding about 1-10% by weight of an activator substance, such as sodium carbonate, sodium hydroxide, lithium carbonate, lithium hydroxide, zinc sulfate, or nickel carbonate, and thereafter compacting the treated clay to obtain improved physical properties, including improved viscosity characteristics, fluid loss and reduction in fines. The process upgrades the properties of poor quality smectite clays so that they can be used in foundry moldwash binders, drilling muds and water impedance applications, such as for sealing ponds, slurry trenches and sanitary landfills.
