الوصف: In this work, the approach for separating paraffin wax is proposed by using Span 80 combined with switchable water N , N , N ′, N ′-tetramethyl-1,6-hexanediamine (TMHDA), where the emulsification of paraffin wax can be promoted and paraffin wax is also separated sustainably. Here, the Span 80-containing mixture system exhibits an enhanced emulsification ability and CO 2 -switchable behavior upon the addition of TMHDA. Then, the paraffin wax is effectively emulsified by this switchable system containing Span 80 and TMHDA. Based on the detection of water separation rate, rheological behavior, and micrographs of emulsified paraffin wax, it is found that the emulsification of paraffin wax can be improved by increasing the paraffin wax content and Span 80 content, and the viscosity of the paraffin wax is reduced after emulsification by this switchable system, which ascribes to the dispersion of wax crystals. In addition, the paraffin wax is separated upon introducing CO 2 , and the TMHDA solution is recovered upon treating with N 2 at 65 °C after separating the paraffin wax. The sustainable separation of paraffin wax results from the aggregation of wax crystals because of the reduced obstruction of oil droplets for wax crystals caused by the high ionic strength and the reduced surface activity of this system upon introducing CO 2 . Herein, it is expected that this sustainable separation can be applied in deposited wax removal in pipelines of crude oil transport.
