摘要 利用炼油厂产生的含油污泥和高硫石油焦,采用萘系分散剂制成油泥焦浆。分别考察了含油污泥处理前后与石油焦的成浆性能。结果表明,未经处理的含油污泥可与石油焦共成浆,但成浆浓度远低于石油焦浆;加入硫酸铁后油泥焦浆表观黏度和流动性得到改善,成浆浓度提高;电解质对浆体的降黏效果优于表面活性剂。含油污泥的加入改变了石油焦浆体的流变类型,随着剪切速率增大,油泥焦浆的表观黏度降低,属于假塑性流体;含油污泥的加入提高了石油焦浆体的稳定性,起到了稳定剂的作用。 The co-slurry ability of the refinery oil sludge and high sulfur petroleum coke and with naphthalene condensate as dispersant was investigated,including concentration,rheology and stabilization.Results showed that oil sludge could mix with petroleum coke to make slurry,but the slurry concentration was lower than that of the single petroleum coke slurry.The apparent viscosity of oil sludge-petroleum coke-slurry was reduced and its flow ability was improved both by the addition of ferric sulfate,at the same time,the slurry concentration was increased.The electrolyte ferric sulfate could reduce the apparent viscosity of oil sludge-petroleum coke-slurry more than surfactant.The addition of oily sludge into the petroleum coke slurry changed slurry rheological type,and as increase of shearing rate,the apparent viscosity of oil sludge-petroleum coke-slurry decreased,so oil sludge-petroleum coke-slurry belonged to pseudoplastic fluid.Oil sludge played the role of stabilizer in oil sludge-petroleum coke-slurry and the more addition of oil sludge,the better stabilization of petroleum coke-slurry.
