Wax precipitation has become a serious problem for the petroleum industry. The problem occurs when there is equilibrium disturbance on the pressure and temperature as well as crude oil composition. Wax deposits will eventually result in restriction of the fluid flow inside the pipeline, and severe deposition will cause blockage. The chemical additives currently being implemented in the industry have various limitations including the high cost and the irreversible impact it has on the environment. Therefore, the use of cheaper organic wax inhibitor obtained from crude palm oil (CPO) and crude palm kernel oil (CPKO) on the rheology and deposition of wax was investigated by using Chenor waxy crude oil from the Penyu basin, Pahang, Malaysia. To compare the efficiency of palm oil additives in inhibiting wax deposition, currently utilized chemical additives such as triethanolamine (TEA) and ethylene vinyl acetate (EVA) were also examined. The pour point of the crude oil was determined using SETA cloud & cryostat, while the rheological behavior of the crude was determined using a rotational Fann viscometer. The results obtained from this study reveal that CPO and CPKO could be used to improve the flow of crude oil, especially when 1 wt.% CPO or when 0.5 wt. % CPKO is used. It was also noted that the palm-based additives were much more effective at reducing the viscosity of the Chenor crude oil than the commercial wax inhibitor tested (TEA and EVA).

蜡沉淀已成为石油工业的一个严重问题。当压力和温度以及原油成分存在平衡扰动时，就会出现问题。蜡沉积最终会导致管道内流体流动受限，严重的沉积会造成堵塞。目前工业中使用的化学添加剂有各种限制，包括成本高和对环境造成不可逆转的影响。因此，使用来自马来西亚彭亨州 Penyu 盆地的 Chenor 蜡质原油，研究了使用从毛棕榈油 (CPO) 和毛棕榈仁油 (CPKO) 获得的廉价有机蜡抑制剂对蜡的流变学和沉积的影响。为了比较棕榈油添加剂抑制蜡沉积的效率，目前使用的化学添加剂如三乙醇胺 (TEA) 和乙烯醋酸乙烯酯 (EVA) 也进行了检查。原油的倾点使用 SETA 云和低温恒温器测定，而原油的流变行为使用旋转范恩粘度计测定。从这项研究中获得的结果表明，CPO 和 CPKO 可用于改善原油的流动性，尤其是当 CPO 为 1 wt.% 或 0.5 wt.% 时。使用 % CPKO。还注意到棕榈基添加剂在降低 Chenor 原油的粘度方面比测试的商业蜡抑制剂（TEA 和 EVA）更有效。而原油的流变行为是使用旋转范恩粘度计测定的。从这项研究中获得的结果表明，CPO 和 CPKO 可用于改善原油的流动性，尤其是当 CPO 为 1 wt.% 或 0.5 wt.% 时。使用 % CPKO。还注意到棕榈基添加剂在降低 Chenor 原油的粘度方面比测试的商业蜡抑制剂（TEA 和 EVA）更有效。而原油的流变行为是使用旋转范恩粘度计测定的。本研究的结果表明，CPO 和 CPKO 可用于改善原油的流动性，尤其是当 CPO 为 1 wt.% 或 0.5 wt. 使用 % CPKO。还注意到棕榈基添加剂在降低 Chenor 原油的粘度方面比测试的商业蜡抑制剂（TEA 和 EVA）更有效。
