Sažetak
Technological waste (tank bottom residues, separator sludges, oily soils etc) is generated during oil and gas production. Part of this waste is considered hazardous. Central oilfield pits (COJ) are used for temporary disposal, pretreatment and final disposal of these waste. After treatment to change the hazardous waste to non-hazardous material it is deposited in a pit area assigned to final disposal of solidified material. Because of the accumulation of inert meterial inside COJs and their limited volume, subsequent disposal becomes problem, and the possibilities for reusing the treated waste have to be considered. The paper contains results of laboratory investigation of new ways of treatment of technological waste from the petroleum industry. The new techniques of treatment are being developed for materials which contain organic or both organic and inorganic pollutants. Samples of technological waste from a central oilfield pit were treated under laboratory conditions with single materials (cement , bentonite, organophillic clay, calcined Moler clay) or different material combinations. A sample of technological waste treated with lime was used for comparison of results. The results clearly show that hazardous technological waste can be treated more effectively by dosing with suitable materials, e.g.organophilic clay, which significantly reduce pollutant discharge from such treated waste into the environment.
