SYSTEM AND METHOD FOR SOIL TREATMENT

摘要

The present invention is directed to a method for irradiating of solids containing petroleum or Petroleum derived compounds (PPDCs), such as soils, oily sludge, drill cuttings, sediments, and non-commercial petroleum industry products, with electron beams in order to physically and/or chemically alter the composition of the PPDCs. The method includes the step of separating PPDC gas and liquids in the presence of a gas driver. Optionally, the method includes the steps of treating off-gases and applying one or more amendments to PPCD-impacted solid material pre-irradiation, post-irradiation, or during electron beam irradiation.

主权项

1. A method for ex situ transformation of petroleum or petroleum derived compounds (PPDC) in PPDC-impacted solid material, comprising:
irradiating the PPDC-impacted solid material with at least one electron beam source; and utilizing a gas driver to separate the PPDC from the PPDC-impacted solid material; wherein the hydrocarbon content of the PPDC-impacted solid materials is less than about 70% by weight PPDC.
