Treatment of ASP produced water with hydrophilic fibre ball filtration
Treatment of ASP produced water with hydrophilic fibre ball filtration
摘要
Abstract
The conventional treatment process cannot meet the need for treatment of produced water from alkaline/surfactant/polymer flooding( ASP produced water) in Daqing oilfield. In this study, a new type of hydrophilic fibre ball medium was developed through surface modification method. The hydrophilic property of the surface modified fibre ball was tested with ASP produced liquid at laboratory. The results showed that this fibre ball had higher oil degreasing efficiency. The surface components were also observed by Scanning Electron Microscope and X-ray Photoelectron Spectroscopy, the result showed that the hydrophilic fibre' s surface was covered by sulfonic group. Using hydrophilic fibre ball as filter medium, a new type of filter was designed to treat ASP produced water in pilot-scale experiments. The obtained results indicated that this type of filter had high capability and efficiency for the treatment of ASP produced water. This filter should have a better application prospect in oilfield produced water treatment.关键词
