摘要：组合纤维聚结(CFC)破乳除油技术基于乳化油滴在亲疏油纤维交叉节点处极性受力不同的原理,针对不同水质参数和操作条件,将不同材质的亲油纤维和疏油纤维组合编织成X型和Ω型结构,再堆叠组装成模块化组件,可实现物理法快速破乳分离。介绍了CFC破乳除油技术在海上油气田生产水处理中的应用情况。该技术仅用单级设备就可以达到传统处理技术两级设备(“斜板除油器+加气浮选器”、“水力旋流器+气浮闪蒸罐”)的处理效果,在占地面积和空间上均优于传统技术,吨水处理药剂成本降低了14%,吨水处理碳排放量降低了88.7%,吨水处理投资成本和运维成本分别降低了11.1%和16.6%。
The combined fibers coalescence(CFC)for demulsification and oil removal is based on the principle that emulsified oil droplets experience different polar forces at the intersection of oleophilic and hydrophobic fibers.According to water quality parameters and operating conditions,oleophilic and hydrophobic fibers with material properties were interwoven into X-type andΩ-type structures,which were further stacked and assembled into modular units to achieve rapid physical demulsification and separation.The application of CFC technology for demulsification and oil removal in the treatment of produced water from offshore oil and gas fields was introduced.With a single-stage system,this technology could achieve the performance equivalent to conventional two-stage systems(e.g.,“inclined plate oil remover+induced gas floatator”or“hydrocyclone+gas flotation flash tank”).It was superior to traditional technologies in terms of both area and space.Moreover,the CFC technology reduced the cost of the agent per ton of water treatment by 14%,the carbon emissions per ton of water treatment by 88.7%,and the investment cost and operation and maintenance cost per ton of water treatment by 11.1%and 16.6%respectively.
