The TCC is based on a completely different principle than the indirect thermal technologies. The TCC converts kinetic energy to thermal energy by creating friction in the waste. A drive unit sets a series of shaft mounted hammer arms in motion inside a barrel shaped process chamber (also referred to as the hammermill or just the mill). The solid particles are forced towards the inner wall of the process chamber where the kinetic energy from the rotating arms will be transformed to heat by friction. The unit can run continuously, automatically controlled by an advanced Plc system. Frictional heat is constantly created by the hammering and motions.
The liquids evaporate and leave the chamber, new waste is pumped in, and solids are discharged through a cell valve. The hottest spot in the process is the waste itself, and the base oil is under influence of high temperature for maximum a few seconds. The oil is re-used by all the largest mud companies as a component in new OBM.
Compared to other thermal desorption technologies, most of the TCC benefits are related to the way theTCC is heating the waste.
