Processing technology:

Treatment of oil sludge and residue with high oil content: oil extraction + thermal desorption of oil-containing sludge (ex situ treatment)

Three-phase separation + thermal drying

Indirect Thermal Desorption/Direct Thermal Desorption

Treatment of contaminated soil with low oil content and heavy metal residues: thermal desorption + reagent stabilization (in-situ treatment)

Indirect thermal desorption (electric heating or steam thermal drive)/chemical oxidation

Heavy metal chelation stabilization
