Methods for the formation and operation of an in situ process reactor

摘要

A hazardous waste site remediation process for decontamination of petrochemical and other toxic waste containing sites comprises in situ conversion of the site to a self contained process reactor which is then selectively operated by feeding a variety of treatment reagents thereto through a network of feed conduits and removing contaminants through removal conduits which collectively bring the contaminated materials to a collection area in the reactor where they can then be further treated or removed. A mobile trenching machine converts the site to a reactor by simultaneously placing contaminant impermeable walls while processing excavated materials such as by adding reactor reagents thereto and then immediately returning the processed materials to the location from which they were excavated in the site. Hydrocarbons or other useful by-products such as precious metals may be recovered from the soil.
