工业油罐底泥处理现状与试验探索

根据油罐底泥产生过程及其特性,分析了原油储罐底泥处理的必要性和经济性,介绍了国内外油罐清理的方法和油罐底泥处理的工艺技术,公布了课题组在开发油罐底泥处理国产化设备方面的试验成果,试验处理效果良好,碳氢化合物回收率达到95％以上,处理后废水符合排放污水处理装置的要求,残余污泥量为原来的12.2％(质量比),为油罐底泥减量化、资源化和处理设备的国产化提供可借鉴范例。

Present Situation and Research of Treatment of Sludge from Oil-tanks

According to the forming and peculiarity of the oil-tank sludge, the paper analyzed the necessity and e-conomic advantage of the treatment of the sludge from oil-tanks, introduced the native and foreign methods of the oil-tank cleaning and the treatment technology of sludge from oil-tanks, and presented the homemade equipment complex, the treatment scheme developed by the author' s experiment group on the aspect of the treatment of sludge from oil-tank, as well as the industrially experimental result. The effect of treatment is good, the recovery rate of hydrocarbon over 95 %, the waste water after the treatment fulfilled the demand of discharging into processing plant, the residua reduced to 12.2%, and final mass for treatment was very little. It provided an useful sample of the homemade and resourceful disposl of sludge from oil-tanks.
