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.
