The principles of thermal treatment
The TCC is based on the basic principle of thermal separation. The OBM cuttings is heated to a temperature sufficiently high to evaporate the oil (and water) from the mineral solids by heating he waste to a temperature higher than the evaporation point of the base oil in the OBM. The oil and water will be condensed back to liquids in later process steps. A common name for such technologies is “thermal desorption” technologies.
There are different ways of heating the waste. In a TCC the heat is created by friction as opposite to indirect heating.
