Abstract

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.

乳化丙烯酸酯聚合物及其降凝性能的评价

传统的降凝剂(PPD)是丙烯酸酯聚合物在室温下呈固态。预热和稀释的成本是原油工业应用的先决条件。因此，为了提高其流动能力，该PPD被临时制成乳液体系。阐述了乳液体系的评价，并对其PPD性能进行了研究。乳化后的PPD可在-20℃的低温下流动。乳化后的PPD在室温下的粘度比传统的PPD低得多，约为16cp。冻融活动使样品的粒径增大，但不影响乳液的稳定性。zeta电位约为-43 mV，表明该乳液处于稳定范围内。乳化产物的倾点性能优于传统的PPD。随着掺量的增加，性能的增加趋势表明，聚合物含量是提高乳化PPD倾点性能的最大影响因素。
