碳化法处理石油废碱渣研究进展 总被引:1,自引:0,他引:1
石油碱渣中含有大量的残余碱、硫化物以及酚类和环烷酸等污染物,故不能直接排入污水厂。碳化法是利用废气中的二氧化碳来处理石油碱渣,是一种高效且成本低廉的石油碱渣处理方法。本文综述了碳化法处理石油废碱渣技术的研究现状,分析了影响石油碱渣处理效果的工艺因素以及技术因素,指出了碳化法处理石油碱渣的应用前景。 相似文献

介绍了液化气脱硫醇碱渣减排技术工业化应用情况。液化气脱硫醇碱渣减排技术是使用液化气纤维液膜脱硫醇及碱液高效再生工艺(LiFT-HR工艺),工业装置运行结果表明,LiFT-HR工艺含硫碱渣年排放量不大于126t,与国内、外同类产品比较,下降60-80%;每年减少碱渣排放量200-630t,降低环保处理费用16-50万元(按碱渣处理费800元/t计算),节约碱液购买费用约10-32万元(按纯碱费用2500元/t计算)。液化气脱硫醇碱渣减排技术工业化应用可降低企业环保处理压力,提升企业环保效益,增加企业的社会美誉度。 相似文献

生物处理液态烃等混合碱渣废水 总被引:1,自引:0,他引:1
运用间歇式活性污泥法(SBR)技术处理某炼油厂液态烃碱渣、催化汽油碱渣和丁辛醇废水构成的混合碱渣,主要考察了COD的去除效果。应用数学模型模拟SBR处理该废水的效果,并求解出了两个模型参数,然后进行了验证。模型显示,该碱渣废水中含有较高的不可生物降解物质。 相似文献

Removal of BOD, suspended solids and oil from vegetable oil refinery waste waters is best accomplished by isolation and treatment
of the most offensive streams. This approach reduces equipment and chemical treatment requirements, recovers by-products of
value and reduces overall costs of waste treatment and operation. A continuous process for clarification of acid water stream
from acidulation is given. Typical data on influent and clarified effluent streams from various refinery areas are presented,
along with process parameters, chemicals and costs.

AbstractData have been obtained in an attempt to use the oily sludge that is a dumped waste of petroleum refineries. The sludge, after purification, was used as a processing aid in the sulphur vulcanisation of styrene/butadiene rubber, in which carbon black is used as filler. Compounds containing aromatic oil were used as the control. Different mixes, containing varying concentrations of aromatic oil/refinery sludge were prepared. The mixes were evaluated for different cure characteristics and the vulcanisates were tested for various physical properties and chemical crosslink density. Aging resistance of the vulcanisates was also evaluated. Processability studies were carried out for the carbon black systems under review. It was found that the optimum cure time is reduced significantly when aromatic oil is replaced completely with refinery sludge. In the evaluation of tensile properties, vulcanisates containing 60% sludge gave the maximum value, while other vulcanisates containing refinery sludge gave values comparable with those containing conventional process aids. It is worthy of note that aromatic oil is becoming prohibitively costly while sludge is a dumped waste of the refinery. 相似文献

Wastes purification by “Ingram” controlled filtration process on tower packed with plastic packing called “panapak” had a new application in purification of waste water containing by-products of a vegetable oil refinery and chemical plant where BOD ranges from 5 000 to 19 000 and pH average 1.5. The biologically controlled filtration unit gives an effluent of BOD 50 by continuous operation. 相似文献
