Abstract
A method for separating hydrocarbon content from a hydrocarbon contaminated matrix. The method includes controlling water content of a feed material having the hydrocarbon contaminated matrix; continuously conveying the feed material into a treatment cavity; exposing the feed material in a treatment area of the treatment cavity to microwave radiation arranged to cause rapid heating of at least a portion of the water content to form steam, wherein the rapid steam formation results in thermal desorption of at least a portion of the hydrocarbon content from the matrix; and continuously removing the treated matrix from the treatment cavity.
