Abstract

The disclosure provides systems and processes for cleaning a site to remove residue from a surface, of one or more surfaces, on the site. The processes can be performed without the addition of water to the site. A process can include: (A) identifying that the residue is liquid hydrocarbon and/or a hydrocarbon; (B) providing clay-based particulates (CBP) for treatment of the surface; (C) providing biosolvent solution (BSS) for treatment of the surface; (D) applying both (a) the CBP to the surface and (b) the BSS to the surface, in a sequential progression of steps, and such applying including: (a) actively identifying if the surface is wet with hydrocarbon; (b) applying a first sequential progression of steps, of the sequential progression of steps, if the surface is identified as being wet with hydrocarbon, the first sequential progression of steps including application of the CBP without the BSS; and (c) applying a second sequential progression of steps, of the sequential progression of steps, if the surface is identified as being not wet with hydrocarbon, and the second sequential progression of steps including application of the CBP and the BSS.
