Abstract

Palm Fatty Acid Distillate (PFAD) as a byproduct of the processed of palm oil has great potential to be used as raw material for polyester synthesis. The purpose of this research is to study ester polymerisation from PFAD with the composition of initiator, time and temperature as the parameters. First, the esterification process was done by the reaction of PFAD and methanol that used sulfuric acid as catalyst. The reactant composition was 1:8 molar ratio, speed of stirrer at 150 rpm, and H2SO4 composition is 1% (w/w) PFAD with temperature at 70° C for 2 hours. The polymerisation process was done by the reaction of esterification stage product and mixed with benzoyl peroxide as initiator. The variation for this stage were the composition of benzoyl peroxide 1%, 5%,and 9% (w/w) of methyl ester, polymerisation time 4, 5 and 6 hours and polymerisation temperatures of 140, 150 and 160° C. The result showed that the esterification stage product was obtained methyl ester and GC-MS analysis showed that the purity of methyl esters is 90,1%. Polymerisation product that is obtained a polyester but still have vinyl group in the component of the product. Based on the results of polymerisation reaction of the end product, dark and thick and has a viscosity of 180-200 cp. Based on the test results of GC-MS the composition of the methyl ester was reduced from 27.67% to 5.62% as the product of polymerization process which mean that the methyl ester have been converted. The R2 in this study gained 0.9663 which means a significant and lack of fit value of 0.1341 which means insignificant then the variable had a p-value of 0,0002 for the model which it less than α = 0.05 with variables that had a significant impact on model.Key words: benzoyl peroxide, palm fatty acid distillate, polyester, synthesis

Abstract

Steam injection is a heat transfer process to petroleum reservoir through multiphase flow of wet steam. Estimating pressure drop in multiphase flow is more difficult than for single-phase flow. Multiphase flow is a complex phenomenon because of the interdependence of various variables that affecting pressure drop such as flow regime, hold up, flow geometry at horizontal, vertical or deviated, flow rate of each phase and the fluid properties of each phase. The purpose of this study is to find out the most appropriate model to calculate the pressure drop in steam injection wells and understand parameters that most affecting pressure drop. Research methodology for this study is descriptive analysis. Field data from 30 injection wells in Duri field are collected and compared with 2 variations of Beggs-Brill and Moody equation, which are the original model and the model with Palmer correction. Both models are translated into a simple computing program using Excel application. Calculation result from the model is compared with the measurement results to understand the deviation or error. As the result of this study, it is shown that Beggs-Brill and Moody model without Palmer correction is suitable for steam injection application. Average error is only 0,2% with a standard deviation of 3,32%. Further information is obtained from the sensitivity analysis that the accuracy of pressure drop calculation is affected by measurement accuracy of the steam flow rate, steam quality and steam temperature. Keyword: Beggs and Brill correlation, Moody diagram, Palmer correction, pressure drop, steam injection.

Abstract

Food packaging aims to protect food products from various physical and mechanical damage. Food packaging that is generally in the form of plastic derived from petroleum is non-renewable, polluting the environment and harmful to human health. One alternative to overcoming this problem is the use of bioplastics that can be decomposed and consumed in the form of edible films. The purpose of this study was to study the effect of levels of carboxymethyl cellulose (CMC) and glycerol plasticizers on mechanical properties and biodegradation of sago starch based bioplastics. Bioplastics were made by mixing sago starch, glycerol (15, 20, 25 % w/w) and CMC (35, 40, 45 % w/w). The resulting bioplastics were carried out by several tests which included tensile strength, elongation, biodegradation and data analysis using Design Expert. The most significant factor affecting all responses was CMC levels followed by glycerol plasticizers. The optimum process conditions were obtained at CMC content 45 % w/w and glycerol plasticizer 15 % w/w with a response value of tensile strength of 8,3 MPa, elongation of 16,8 % and biodegradation 51 %. Keywords: bioplastics, CMC, filler, glycerol, sago starch, RSM
