Improvements in Treatment of Waste From Petroleum Industry in Croatia

摘要: Exploration and production (E&P) waste generated by the petroleum industry in Croatia from two central oilfield pits (COPs) was investigated order to (1) examine materials for treatment that can preferentially sorb organic contaminants and, way, improve process of stabilization/solidification (S/S), (2) find field-acceptable methods reduce amount be treated with S/S or some other method. Composite samples COP Vinkovci were laboratory different combinations several materials: (a) Cement, (b) organophilic clay, (c) calcined moler (d) lime+organophilic clay+bentonite, (e) cement+organophilic (f) lime+calcined (g) cement+calcined clay. A sample E&P lime used comparison results. The most successful majority inorganic pollutants Samples clay release 63 times less total oils, 67 mineral 798 naphthalene, 136 lead distilled water than lime. next material is results clearly show reduction hydrocarbon content using detailed chemical analysis remaining must implemented before selecting appropriate method technological industry. composite Žutica a four-step procedure involving boiling water, condensate, Organophilic because its ability hydrophobic pollutants. In leachate an sample, lowest values observed following fourth step (treatment clay). This also manifested indicator discharge (ITD%) step. Considering concentrations analyzed parameters leachates their ITD% values, biggest effect achieved between first second suggests effective Concentrations benzene, ethylbenzene, toluene, xylene (BETX) distilled-water generally increase after each succeeding shows BETX added through condensate addition third
