Abstract:
1. A system for removing at least one of hydrocarbons and heavy metals, the system comprising: a hydrocarbon removal mobile unit comprising: (i) a first trailer; (ii) a hopper for receiving input material; (iii) a rotating material moving device disposed in the hopper for ensuring continuous flow of input material through the hopper; (iv) a controller for controlling the speed of the rotating material moving device; (v) 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; (vi) 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: (vii) 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; (viii) at least one scalper tank wherein each scalper tank comprises a scalper agitator forming a suspension from the second slurry; (ix) 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; (x) a desilting screen for receiving the second hydrocarbon extracted particulate; (xi) a desilting tank containing a desilting agitator for receiving the third slurry and forming an agitated third slurry; (xii) 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; (xiii) a clay screen for receiving the third hydrocarbon extracted particulate; (xiv) a clay slurry tank with a clay agitator for receiving the fourth slurry; (xv) 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; and a heating and power support unit for connecting to the hydrocarbon removal mobile unit providing power and a heated second fluid to the hydrocarbon removal mobile unit, wherein the heating and power support unit comprises: (i) a second trailer adjacent the first trailer; (ii) a generator disposed on the second trailer; (iii) a fuel tank disposed on the second trailer and in communication with the generator; (iv) a boiler in communication with the generator; (v) a fluid intake in the boiler for receiving the second fluid from a second fluid source; and (vi) a heated fluid outlet of the boiler in communication with a heated fluid dispersal manifold disposed on the hydrocarbon removal mobile unit.
