Abstract: Toxic liquids, especially halogenated aromatic hydrocarbons, are immobilized within a container by dispersing cryogenically comminuted polymer particles in a surface active state throughout the liquid. The polymer is injected into a container holding the toxic liquid as a slurry of particles in a cryogenic refrigerant. Use of a heat, shear or radiation degradable polymer as the immobilizing agent allows the solidified liquid to be returned to a fluid state for later disposal by incineration.

Abstract: Spilled liquid hydrocarbon products ranging from crude oil to refined fractions and discrete compounds are converted from a liquid to a gel or to a semi-solid or solid state by contacting a liquid petroleum product with a slurry of cryogenically comminuted polymer particles in a liquified refrigerant gas. The technique is particularly appropriate for control of oil spills in a water environment wherein the oil is either floating on or dispersed in water. Contact of the polymer particles with liquid hydrocarbons results in virtually instantaneous solvation of the polymer in the hydrocarbon to produce a cohesive gel or a semi-solid to solid material at a polymer concentration ranging generally from about 0.2% to 1% for gel formation and from about 1% to 30% for formation of a semi-solid to solid material based on hydrocarbon weight.

Abstract: This invention provides a technique for extremely rapid dissolution, or dispersion on essentially the molecular level, of certain polymeric materials in compatible liquid vehicles. The polymeric materials are comminuted at cryogenic temperatures and are then introduced into a liquid vehicle preferably while still at or near cryogenic temperature. At low concentrations, the resulting blend or system displays reduced friction to flow while high concentrations may be used to immobilize the liquid vehicle and/or reduce its vapor pressure.

Abstract: Solid sorbents such as activated carbon and ion exchange resins are ballasted with finely divided particles of a non-corrosive, magnetic iron-chromium alloy to increase their effective specific gravity and to render them recoverable by magnetic means. The sorbents are used to selectively extract one or more constituents contained in a liquid as by contacting in a multi-stage fluidized bed.
