Abstract:
1. A hydrocarbon removal mobile unit comprising: a. a first trailer; b. a hopper for receiving input material; c. a rotating material moving device disposed in the hopper for ensuring continuous flow of input material through the hopper; d. a controller for controlling the speed of the rotating material moving device; e. a plurality injection ports adjacent the rotating material moving device within the hopper for introducing a first fluid to the input material forming a first slurry; f. a separation tank for receiving the first slurry, agitating the first slurry, and allowing particulate to settle, forming a separated contaminate and a particulate effluent, wherein the separation tank comprises: g. at least one scalper screen for receiving the particulate effluent and separating the particulate effluent into a first hydrocarbon extracted particulate with a diameter greater than 1000 microns and a second slurry; h. at least one scalper tank wherein each scalper tank comprises a scalper agitator forming a suspension from the second slurry; i. at least one de-silting hydrocyclone for receiving the suspension and removing a second hydrocarbon extracted particulate with a diameter greater 75 microns, forming a third slurry; j. a desilting screen for receiving the second hydrocarbon extracted particulate; k. a desilting tank containing a desilting agitator for receiving the third slurry and forming an agitated third slurry; l. a plurality of clay extractors for receiving the agitated third slurry and removing a third hydrocarbon extracted particulate with a diameter greater than 10 microns, forming a fourth slurry; m. a clay screen for receiving the third hydrocarbon extracted particulate; n. a clay slurry tank with a clay agitator for receiving the fourth slurry; and o. a heating device disposed within the clay slurry tank and in fluid communication with at least one of the desilting tank, the scalper tank, and the initial separation section.
