System and process for decontaminating soil

摘要

A process for removing hydrocarbon contaminants from contaminated soil. One or more additives comprising solutions of one or more of alcohols and polyols are added to the soil, and the soil/additive mixture is stirred. This causes the contaminants to be at least partially removed from the soil. At least some of the hydrocarbon contaminants are removed from the mixture by flotation, and recovered by skimming.
