Thermal desorption of pretreated acid tar

Thermal desorption of pretreated acid tar = Termická desorpcia predupravených kyslých ropných kalov / Anna Bohers, Emília Hroncová, Juraj Ladosmerský [elektronický dokument]. -- Acid sludge is an industrial waste generated during petroleum oils refining with chemical agents, especially sulfuric acid. It is toxic, cancer-causing, teratogenic, mutagenic and it is classified as hazardous waste. 30 years ago acid sludge was placed in pre-explored pitches without any security measures against its penetration into the environment. It is urgent to eliminate this kind of waste with appropriate technology. Thermal desorption has been chosen as possible option of its processing, which uses oxygen-free heat treatment to reduce emissions to as low level as possible. Tests on the thermal desorption unit were performed to indicate the technology effectiveness during acid sludge processing and the change in weight of the before stabilized waste in relation to the desorbed matrix as residual material after the processing. The secondary objective during acid tar processing was to obtain different samples of oil fractions at different temperature-pressure conditions
