Abstract

The length and diameter of the fibers of palm frond is one of the factors that affect the physical and mechanical properties of the material WPC. This study aims to determine the effect of fiber diameter and length of the palm fronds to the properties and morphology of wood plastic composite (WPC). WPC samples prepared by the method of melt blending the fibers of palm fronds, PP, Maleated polypropylene (MAPP), and paraffin for 65 minutes at a temperature of 170 ° C and a rotor speed of 80 rpm using the Internal Mixer.

Abstract

Bioplastics are an alternative material to replace conventional plastic packaging so as not to pollute the environment. One method of modifying bioplastics is the acetylation method which is a modified starch method obtained from reacting starch with hydroxyl groups to produce hemiacetal and aldehyde. This study aims to make modified bioplastics with better tensile strength than ordinary bioplastics. The analysis performed was FTIR test, substitution degree test, and mechanical properties of tensile strength. The best results from each test are the value obtained by the value of the substitution degree 0,992, FTIR at the vibration for the wavelength range 1633 - 1645 cm-1, the tensile strength value of 1,893 MPa bioplastically penetrated the decay results of the methylated starch and 12 % filler content b / b and 10 % plasticizers b / b.Keywords : acetylation, bioplastic, acetylated starch, acetylated bioplastic

Abstract

Palm trunk wood is one of solid waste from palm plantations that have not been utilized optimally. This waste can be developed as materials for Wood Plastic Composite (WPC). Extractive substances and hemicellulose fraction of this material may inhibit mixing process between wood filler and matrix, so it takes a pretreatment to eliminate these fraction. Effect of pretreatment on the properties and morphology of the resulting WPC studied in this research. Pretreatment was performed in an autoclave using water and solution of oxalic acid (OA) with concentration 0,05 M and 0,1 M at soaking temperature 1000C and 1400C then held for 5 and 15 minutes. Mixing the filler and matrix with the ratio 30/70, 2% mass paraffin and 5% mass of Maleic Anhydrate Polypropylene (MAPP) was conducted on Internal Mixer Labo Plastomills with temperature and rotor speed conditions 170 0C and 80 rpm respectively. Results of the lignocellulose analysis showed that highest reduction of extractive substances and hemicellulose fraction was 95,94 % and 25,22 %. The best mechanical and physical properties found in the pretreated sample with conditions 0,05 M OA concentration, 140 0C soaking temperature, and 15 minutes soaking time. The tensile strength, flexural strength, and water absorption values was 273,244 kgf/cm2, 427,551 kgf/cm2 and 1,120 %, respectively.Keywords : filler, lignocelluloce, pretreatment, wood plastic composite

Abstract

The pulp and paper industry is a water-intensive industry, and number third in the world and also a significant contributor to pollutant discharge to the environment. It is know that the low COD/BOD ratio obtained from pulp industry wastewater is an average of 0.3 while the ideal of biodegradability value is in the range above 0.5. Thus, there are alternative treatments that can degrade hazardous compounds in wastewater that are slow to degrade through the oxidation process, known as the Advanced Oxidation Process (AOP). AOP is based on active radicals which are produced as oxidizing agents to mineralize the complex chemical substance in the wastewater. One of the active radicals, known sulfate radicals (SO4*), has a high oxidation potential of 2.5 – 3.1 V. Several studies showed that radical sulfates can be produced by catalytic oxodation process, such as combination of Peroxymonosulfate with homogeneous metal ion catalyst (Fe2+, Mn2+, Ni 2+, Co2+, Cd2+, Cu2+, Ag+1, Cr3+, Zn2+). In this study, AOP method peroxymonosulfate which was activated with the catalyst α-MnO2-400 were used to treat organic content in wastewater of pulp and paper industry. The α-MnO2-400 catalyst was produced from 1:3 molar potassium permanganate (KMnO4) and maleic acid that calcined at 400oC. This catalyst was characterized by XRD, BET and FESEM. From XRD analysis obtained the peak aligned with JCPDS Standard. From the BET analysis obtained surface area is 49.17 m2/g, pore size 6.4 nm and pore total 0,16 cm3/g. From FESEM analysis obtained crystalit structured with average length 21 nm. The best degradation of COD and TOC concentration obtained at temperature 45oC, at retention time 240 minutes, with peroxymonosulfate concentration 2,0 g/L and catalyst concentration 0,4 g/L (73% and 77%).

Abstract

Palm Fatty Acid distillate (PFAD) as a byproduct the processing of palm oil has great potential to be used as raw material oil-based polymers. The aims of this research to study the process polymerization of ester from PFAD using initiator (benzoyl peroxide) 0.3%. Stage of the process consists of three stages. The esterification stage was done at temperatur70° C, reaction time of 120 minutes, reactant ratio 1: 8 (PFAD: methanol), concentration of catalyst (H2SO4) 1% (w/w) PFAD; polymerization stage was done at temperature 120, 130,and 140°C, concentration of initiator (benzoyl peroxide) 0.3% (w/w) and variation of polymerization reaction time 3, 4, and 5 hours, and polyesterification stage was done at temperature 175-200 °C, ratio of reactants 1: 1 (polymerized methyl ester: ethylene glycol), and the reaction time of 4 hours. The results of polymerization was analyzed by using viscosity test, FT-IR (Fourier Transform Infra Red) and GCMS (Gas Chromatography Mass Spectrometry). The highest viscosity was 32,97 mPa.s at temperature 140°C and 4 hours. Theresult using FT-IR showed that the polymerization process was unsuccessful, this was indicated by the presence of the vinyl group. The result of GCMS showed there had been molecular weight addition in polymerization process, that was only three times the initial molecular weight.Keywords: benzoyl peroxide, esterification, palm fatty acid distillate, polymerization

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.
