Dispersion of oil-tank sludge using compositions of cationic, anionic, and nonionic surfactants followed by isolation of synthetic oil is a processing method with several disadvantages such as residual S-containing compounds and toxic spent solutions. The present work proposes the use of polycomplexants (sodium salts of iminodiacetate derivatives of fatty-acid triglycerides and mucosaccharides) as promising and affordable replacements for traditional surfactants. A methodology for processing oil-tank sludge using these compounds and results of laboratory tests showing decreased S contents and significantly lower densities and viscosities of the oil-tank sludge are given.

使用多络合物和氨基酸盐通过水热分散处理油罐污泥

使用阳离子、阴离子和非离子表面活性剂的组合物分散油罐污泥，然后分离合成油是一种具有若干缺点的处理方法，例如残留的含硫化合物和有毒的废溶液。目前的工作建议使用多络合物（脂肪酸甘油三酯和粘糖的亚氨基二乙酸衍生物的钠盐）作为传统表面活性剂的有前途且价格合理的替代品。给出了使用这些化合物处理油罐污泥的方法和实验室测试结果，表明油罐污泥的 S 含量降低，密度和粘度显着降低。
