Thermal Desorption of Drill Muds and Cuttings was first used in the beginning of 1990s.  Hence, this technology was improved significantly  due to the introduction of the stringent environmental requirements and standards followed by  the increased recovery of hydrocarbons. The amounts of hydrocarbon mixtures used in drilling fluid systems have increased due to the use of diesel fuel,  mineral oils and wide range of synthetic oils.

Different types of hydrocarbons are present in drilling wastes. Drill cuttings include drilled rock, water, oils, crude oil and different additives used in drilling fluid systems. The wastes contain hydrocarbons mixed with water and cuttings, as well as different emulsions and  hydrocarbons from the pores of drilling cuttings.

The treatment technology is based on the thermal processes resulting in evaporation of liquids from drilling cuttings, including: hydrocarbons and water. Water evaporates first, turning into water vapour, and hydrocarbons evaporate later, as they have a higher boiling point. Hydrocarbons are separated from water during the two stage condensation process, based on the same principles. 

The hammer mill generates large quantities of heat during the grinding process, thus breaking cuttings and removing liquids, including pore fluids.  The design provides reduction of thermal energy to minimum and simultaneous removal of liquid components  with recovery of hydrocarbons for further re-use in oil-based drilling fluids.


  • It removes 99% of solids
  • It is environmentally friendly
  • It entails no direct combustion
  • Recovery of oil or synthetic-based drilling fluids and water



The recovered fluid storage tanks are designed for containment of water and oil base, coming from the TCC unit.

Four tanks, 25 m3 each, are installed on the skids; the tanks are connected and equipped with the service/ maintenance platform on the top of the skids.
