This unique Indirectly-fired thermal extractor system (Indirect heat thermal desorption system) uses indirect thermal desorption to recover and recycle hydrocarbon contaminated solids for safe on-site disposal. This is a portable system designed to thermally remove hydrocarbons from solids. The hydrocarbons are extracted pyrolitically and recovered as oil and/or fired to heat the process.
System can process various materials such as:
- Hydrocarbons contaminated soil (results of oil or fuel spillages, etc);
- Solid fraction after processing sludge from oil ponds or lagoons on centrifuge;
- Sediments from oil and bunker oil tanks;
- Spend catalysts used in oil refineries, etc.
The thermo- desorption system can process material with following parameters:-
- Hydrocarbons, up to 25% by weight
- Water, up to 30% by weight
