Abstract
The invention relates to a chemical composition and a process for using the chemical composition to remove and recover petroleum hydrocarbons from a contaminated substrate including an ammonia compound; a nitrogen-containing compound; and an aqueous carrier solution.
Claims22
A process for cleaning petroleum hydrocarbons from a substrate, the process comprising;
- introducing a chemical composition into the substrate in an amount effective to, when added to the substrate, substantially separate the petroleum hydrocarbons from the substrate without the formation of an emulsion, wherein the chemical composition comprises:
- an absence of a surfactant;
- an alcohol compound;
- a nitrogen-containing compound;
- and
- an aqueous carrier solution, the aqueous carrier solution being of sufficient volume operable to disperse at least one of the nitrogen-containing compound and the alcohol compound in the aqueous carrier solution, the nitrogen-containing compound and alcohol compound being substantially distributed throughout the aqueous carrier solution, the concentration of the nitrogen-containing compound and alcohol compound in the chemical composition being an amount effective to promote the separation of the petroleum hydrocarbons from the substrate;
- and
- removing the petroleum hydrocarbons from the substrate.
