A transportable separation apparatus for separating spent materials from oil and gas operations into a primarily solid component, a primarily liquid component and a primarily gas component. The transportable separation apparatus includes a first separation unit disposed on the transportable separation apparatus for receiving spent materials and beginning separation of the spent materials. The transportable separation apparatus connectable to a vehicle to be pulled on commercial roadways when the transportable separation apparatus is in a transportation configuration. The transportable separation apparatus further includes a second separation unit in fluid communication with the first separation unit for further separation of the spent materials. A method of using the transportable separation apparatus to separate spent materials.
