Abstract

In search of environmentally friendly petroleum processing, three bio-demulsifiers were synthesized from Nigerian vegetable seed oils. The synthesized vegetable seed oils were Mahogany, Neem, and Calabash. Their oils were mechanically extracted and mixed with liquid detergent, camphor, starch, and paraffin wax to form bio-demulsifiers. The green demulsifiers produced were mixed with synthetic crude oil in the ratios of 0.5:50, 1:50, 1.5:50, 2:50, and 2.5:50 volume/volume in mL. Studies on the effects of their concentration in the demulsification of water-in-oil emulsion were conducted. Mahogany demulsifier of formulation M8 1.5:50 and M8 2:50 (volume of demulsifier to the volume of synthetic crude) had 78% performance. This was followed by N8 1.5:50 which had 77% performance. The highest 70% water removal performance by calabash demulsifiers was recorded by C1 0.5:50, C1 2:50, and C1 2.5:50. The lowest performance was recorded by N1 1:50 and N1 1.5:50 which had a performance of 35% water removal. With these results, Mahogany seed oil can be conveniently used to prepare bio-demulsifiers to save our environment and production cost.
