Abstract

Systems, methods and apparatus are provided for utilizing a substantially condensed phase cryogenic fluid for the purpose of remediation and retrieval of, e.g., spilled crude oil and other “oil spill”-related products from marine/aquatic and terrestrial environments. In some implementations, systems and apparatus are provided for applying a substantially condensed phase cryogenic fluid to a volume of spilled oil, and further having structure for collecting the spilled oil. Some implementations are environmentally-neutral. Substances other than oil may be remediated as well.

Claims

1. A method for remediating an immiscible pollutant comprising:

providing a flow of cryogenic fluid;

maintaining the cryogenic fluid in a substantially condensed phase;

apply the substantially condensed phase cryogenic fluid to at least some of the immiscible pollutant;

collect at least some of the immiscible pollutant after the cryogenic fluid has been applied; and

store the collected immiscible pollutant.

2. The method of claim 1 comprising:

detecting the thickness of the immiscible pollutant; and

adjusting the rate at which the substantially condensed phase cryogenic fluid is applied based on the detecting.

3. The method of claim 1 comprising:

detecting the thickness of the immiscible pollutant;

storing data representative of the detected thickness in a data store;

detecting the temperature of the immiscible pollutant,

adjusting the rate at which the substantially condensed phase cryogenic fluid is applied based on the temperature and at least some of the data in the data store.

4. The method of claim 1 comprising inducing viscous agglomeration of the immiscible pollutant.

5. The method of claim 1 comprising inducing accretion and encapsulation of the immiscible pollutant.

6. The method of claim 1 comprising inducing sequestration via lattice uptake of the immiscible pollutant.
