SINTESIS ALKIL ESTER DARI MINYAK MAGGOT DAN UJI KINERJANYA SEBAGAI POUR POINT DEPRESSANT (PPD)

Abstract

This Final Assignment research focuses on the synthesis of alkyl esters from maggot oil and their performance evaluation as Pour Point Depressants (PPDs) in lowering the pour point of crude oil. In crude oil processing, one of the main concerns is wax deposition in transportation pipelines, which can hinder the production process. This deposition occurs because crude oil is composed of a large amount of hydrocarbon compounds, including paraffin wax. Therefore, Pour Point Depressants (PPDs) are needed to prevent paraffin wax deposition. This study aims to produce PPDs by synthesizing alkyl esters from maggot oil. Maggot was chosen because it contains 29 – 32% fatty acids so it is considered to have the potential to be processed into PPD. This makes maggots a promising material for PPD production. PPD synthesis was carried out through an esterification process using a reflux method. Characterization of the PPDs using FTIR revealed C-H stretching vibrations at 2920 cm-1, indicating the formation of ester groups. GC-MS analysis was also performed to determine the amount of alkyl esters formed. PPD 2 exhibited the highest alkyl ester content (98.60%), while PPD 1 had a lower content (59.20%). The performance of the PPDs was evaluated by measuring the pour point of crude oil using the ASTM D-5853 method. PPD 2 showed the greatest reduction in pour point (12°C) compared to the blank pour point (45°C).
