Abstract: A system for cleaning slurry containing drilling cuttings or drilling fluids may include a slurry sump, separator, screen, liquid tank, surge hopper, and a cleaner. The cleaner may further include a rotary retort furnace which may both dry the slurry to a cake and oxidize any organic matter. The furnace may operate at a temperature of between 1200° F. and 2000° F., inclusively. The cleaning system may recycle the liquid used by returning it to the truck that brought the slurry, or, in the case of drilling fluid, collecting the liquid for use as a fuel source or reconstituting the drilling fluid by mixing the liquid with the cake after heating. The cleaned slurry produced by the system may be suitable for re-use or non-hazardous disposal.

Abstract: According to at least one exemplary embodiment, a system for cleaning fracking waste slurry containing water, sand, and organic matter may include a slurry sump, separator, dewatering screen, water tank, surge hopper, and a sand cleaner. The sand cleaner may further include a rotary retort furnace which may both dry the sand and oxidize any organic matter. The cleaning system may recycle the water used by returning it to the truck that brought the waste slurry. Further, the dried and cleaned sand produced by the system may be suitable for re-use or non-hazardous disposal.
