Abstract
Provided are systems and methods that are related to a fluid processing unit. A method for separating a drilling waste fluid, the method comprising: introducing drilling waste fluid into a thermal extraction chamber; allowing drilling waste fluid to flow longitudinally along two screws disposed within thermal extraction chamber, wherein each screw comprises a shaft, an orifice, and an internal heating element; allowing internal heating element to provide heat to thermal extraction chamber; allowing at least a portion of the drilling waste fluid to evaporate; removing evaporated fluid through a first outlet; removing solids through a second outlet. A thermal extraction chamber for separating drilling waste fluids, wherein thermal extraction chamber comprises: a barrel; a first screw; a second screw, wherein first screw and the second screw comprise a shaft, an orifice, a an internal heating element; an inlet port; a first outlet port; and a second outlet port.
