摘要

在石油石化工业中，油泥是造成环境污染和资源浪费的常见污染物。目前，从含油污泥中回收原油在处理过程中面临着重大挑战。本研究开发了一种碳酸氢铵基co2响应微乳液，以有效处理污泥和回收原油。该微乳液体系具有较强的增油能力。微乳液处理后，污泥中残油含量可降至2.93% （ME-1、正丁醇为助表面活性剂）和1.44% （ME-2、正己醇为助表面活性剂）。通过在65℃下引入N2可以实现完全的油水相分离。

Oil recovery from oily sludge using amidinium bicarbonate-based CO2-responsive microemulsion

In the petroleum and petrochemical industries, oil sludge is a common contaminant that causes environmental pollution and resource wastage. Currently, recovering crude oil from oily sludge presents a significant challenge during processing. In this study, an amidinium bicarbonate-based CO₂-responsive microemulsion was developed to effectively treat sludge and recover crude oil. The microemulsion system demonstrates a strong capability for oil solubilization. After the microemulsion treatment, the residual oil contents in the sludge can be reduced to as low as 2.93% (ME-1, n-butanol as cosurfactant) and 1.44% (ME-2, n-hexanol as cosurfactant). Complete oil/water phase separation can be achieved by introducing N₂ at 65°C.
