| Popis: | Crude oil emulsion is an uncontrollable process that mostly happened at the oil rig during drilling or recovery of oil. Emulsion creates problems at the oil refinery and can cause corrosion in the processing equipment and pipeline. Demulsification is a method used to separate water in the crude oil emulsion where the demulsifier can break interfacial surface of the water droplets to coalesce with each other. Chemical demulsifier is conventionally used by industries as it promises good and fast separation in water-in-oil emulsion. However, chemical demulsifiers may increase water toxicity and become harmful to the aquatic lives if discharged to the water resources. Therefore, the use of green demulsifier is important for industries to reduce the impact to environment. The ability of coconut oil and its derivative, coco betaine as green demulsifiers was investigated in the present study. Effects of different parameters such as temperature (25–70 °C), demulsifier dosage (1–4 ml) and ratio of additive-to-demulsifier (0:1, 1:2, 1:1, 2:1, 1:0) have been studied to examine their impacts on the performance of demulsifiers. Bottle test method was used to analyse the separation of water in crude oil. Results revealed that coco betaine has better performance as a green demulsifier (≈35% of water separation) compared to the coconut oil ( |
