This project is about the demulsifier formulation by using plant extract to produce a green demulsifier. Demulsifier is an oilfield chemical that is used to be injected into Water-in-Oil (W/O) emulsion to be separated into water and oil. Current conventional demulsifiers that available in markets are likely to give bad impacts towards the environment due to high toxic level. The objective of this project is to study and select the most suitable plants that have high potential to be used as green demulsifier. This project is also to observe, evaluate and develop the performances assessment of the plant extracts towards the synthetic emulsion crude sample.
The plants that used are green tea, olive and coconut because of the fatty acid, naphthenic acid and polyphenols content. There are five main processes involved in this project which are samples preparation that used Soxhlet Extraction method to extract the plants, identification of the plant extract’s compositions using Gas Chromatography Mass Spectrometer (GC-MS), static and dynamic bottle test, toxicity level test and performance assessment development. In order to provide the significant impact of the plant extracts and also as the comparison purpose, the author also formulated blend demulsifier from local materials such as starch, camphor, Calcium Hydroxide Ca(OH
, Sodium Hydroxide NaOH, paraffix wax, liquid soap and distilled water.
Based on the results obtained from both static and dynamic test, there are six best formulations that give good results from all 23 of formulations which are SR1637, B2, E2 and E3 which are olive and coconut extract, FE2 and FI1. SR1637 is the industry chemical that currently used, B2 is a blend demusifier that consists of NaOH, E3 extract and other materials like starch, camphor, paraffin wax, liquid soap and distilled water, FE2 is a combination of two best plant extracts which are E2 and E3 and FI1 is the combination between E3 and SR1637. In terms of toxicity level, B2 is the most toxic demulsifier as the pH value is 12 means that it has alkali property and E3 contain the least toxic level as the pH value is 6 that is a neutral demulsifier. From all of these six formulations, E3 extract give the best performances in separation process of W/O emulsion.
