Oil sludge neutralization methods. Neutralization of oil sludge by incineration

Oil sludge is a solid or pasty oil-containing waste, which heterophase system of organic, water and mineral parts in the form sand, dust, silt, metal compounds, ratio varies over very wide range. formed during construction oil gas wells, direct extraction useful component, refining, purification oil-polluted waters reservoirs. This waste that generated large enough quantities, for placement areas are alienated organization pits, leads to significant costs organizations pay storage. Also, such storage, damage also caused environment due evaporation products from areas, pollution soil case loss integrity by insulating material. The objectives study were evaluate effectiveness neutralization burning at temperature 900°C assess safety using resulting ash as secondary resource technical needs fields. following indicators determined author: amount — gravimetric method, humidity thermogravimetric content gross (As, Sb, Sn) mobile (Co, Cr, Mn, Ni, Zn, Pb) forms heavy metals method atomic absorption spectrometry. Based on nature curve, one can judge absence ash. When analyzing ash, slight excess MPC arsenic (2.77 mg/kg versus 2 mg/kg) more than 2.5 times nickel (10.5 4 mg/kg), therefore, before industrial needs, involving contact with ground, must be mixed, example, 1:2.6, respectively.
