Evaluation of Emulsified Acrylate Polymer and its Pour Point Depressant Performance

A traditional pour point depressant (PPD) of acrylate polymer is in solid form at room temperature. The costing for preheating and dilution is a prerequisite to be considered for its utilization in a crude oil industry. Hence, this PPD was improvised as an emulsion system in order to increase its flow ability. Evaluation of the emulsion system has been elucidated and its PPD performance has also been studied. The emulsified PPD could flow as low as -20 oC. The viscosity of emulsified PPD is much lower which is about 16 cP while traditional PPD solid at room temperature. The particle size of the sample increased by freeze thawed activities, but does not affect the stability of the emulsion. The zeta potential is about -43 mV showing that the emulsion is in the stable range. The pour point performance of emulsified product is better compared to traditional PPD. The increasing trends of performance by increasing the injection showing that the polymer content is the most influenced factor that increased pour point performance of emulsified PPD.
