Abstract

Pulp production always has a bleaching process that uses chlorine dioxide (ClO2) as a bleaching pulp agent. One of the ClO2 production units that are used in the Pulp Industry in Indonesia is a ClO2 R8 non-integrated plant with the process of reacting sodium chlorate, sulfuric acid, and methanol. This ClO2 production type has a weakness, especially in supplying the raw material sodium chlorate, which is needed to import, and the characteristics are easy to explode, making production costs high. This research aims to modify the ClO2 R8 non-integrated by changing to a ClO2 semi-integrated plant. In this research, HYSYS was used to simulation to get mass and energy balance and other component data, and the design of equipment based on the American Society of Mechanical Engineers (ASME), Kern, internal data company, and others to get the specification equipment and also drawn using Autocad. The last step is to account for the economic for getting cost of production before and after modification, fixed capital cost, benefit, payback period, and return on investment. The resulting area, the first, modification of the ClO2 R8 plant by changing to ClO2 semi-integrated could produce chlorate solution 510 g/l which they use electrolyzers system from Chemetics with 20 cell M25 and hypo system. Second, the cost production for the ClO2 semi-integrated plant is 1393 USD/T, the benefit is 599.79 USD/year, the Payback period (PBP) is 6,65 years with an investment of about 3988 KUSD and RoI 15%.

Abstract

Duri steam flood is the largest hot steam injection project in Indonesia, facing challenges in preventing production declines. Objective project is showed decrease in production due to crustal deposition (scale). The Stiff and Davis method shows a Stability Index of 1.43, with a tendency for scale formation, especially CaCO3, in accordance with the Ryznar method. Increasing the production of x, yz layer wells in the Duri field, designing acidification stimulation with a pumping pressure of 400 psi, an injection rate of 2 bbl/minute and an acid volume of 600 gallons, after that comparing the performance of hydrochloric acid and carboxylic acid. Analysis showed that hydrochloric stimulation resulted in a significant increase in production of 115 BFPD / 8 BOPD (42% increase), while carboxylate stimulation showed a slower increase of 40 BFPD / 3 BOPD (24% increase). An economic evaluation shows chloride acidification produces an annual NPV gain of $48,002, compared to carboxylate acidification with an annual NPV gain of $22,554. Thus, chloride acidification proved to be economically profitable for the x, yz layers in the Duri field. This study highlights optimal acid stimulation strategies to mitigate scale-related production challenges in steam flood projects.

Abstract

Waste oil empty palm fruit bunches (EFB) one of the renewable energy sources with great potential and is produced approximately 21% of the entire palm oil processing process. Burning EFB briquettes using biomass stoves has a low combustion efficiency, so it has the potential to emit CO. The aim of this research is to determine CO gas emissions resulting from burning empty palm fruit bunch briquettes with variations in the number of holes in the biomass stove and compare them with the quality standards of Minister of Energy and Mineral Resources Regulation No. 047 of 2006. and see how the effect of air hole openings on biomass stoves with empty palm fruit bunch briquettes. In this study, co emission test was conducted using environmental combustion analyzer type 450 and biomass stove performance using water boiling test method. Testing was conducted with variations of air hole openings L1 (3.51 cm2), L2 (7.03 cm2), and L3 (10.55 cm2). The results of CO gas testing obtained by L1, L2 and L3 are 523.54 mg/ Nm3, 425.59 mg/ Nm3, and 351.13 mg / Nm3 and still meet the quality standards of ESDM no. 047 of 2006. Thermal efficiency of briquette stoves obtained in L1, L2 and L3 are 26.51%, 24.28% and 22.28% and for specific consumption rates obtained in L1, L2 and L3 are 3.47 grams/minute, 5.54 grams/minute and 7.17 grams/minute, this result didn’t meet the quality standard of SNI 7926-2013. Based on the results of the study, it was concluded that the smaller the opening of the briquette stove air hole, the more CO emissions produced, the higher the thermal efficiency and the smaller the consumption rate.

Abstract

Eucalyptus oil is one of the essential oil obtained from the extraction of eucalyptus leaves. The purpose of this study is to evaluate the effect of variations in sample treatment and extraction time on the yield of eucalyptus essential oil and determine the characteristics of eucalyptus essential oil produced by the hydro distillation method. Variations in sample treatment were carried out by chopping, crushing, and blending dry eucalyptus leaves. 500 grams eucalyptus leaves are weighed and put in a 2000 mL flask. ±1000 mL of distilled water was added and the extraction process was carried out for 5, 6 and 7 hours. The results showed that the highest yield was obtained from blending treatment with an extraction time of 7 hours with a yield of 0.58%. Characteristic tests on eucalyptus leaf essential oil included: color, odor, specific gravity, refractive index and solubility in ethanol 80%. From the analysis of the test results, the color of eucalyptus oil is cloudy. The odor test results obtained are the distinctive odor of eucalyptus. The best value of eucalyptus oil specific gravity was 0.913 on crushed leaves for 6 hours. In the ethanol solubility test, the resulting oil dissolves in ethanol and a clear solution is obtained. The highest refractive index value of eucalyptus oil on chopped leaves for 5 hours is 1.469. Eucalyptus oil has a quality in accordance with the quality requirements of SNI 3954: 2014.

Abstract

Research has been conducted to manufacture Ni/NZA for catalytic cracking of empty palm fruit bunches into liquid fuel. The study aims to investigate the impact of metal impregnation and calcination time variations on catalyst crystallinity and morphology. The catalyst is produced in multiple stages, including NZ activation using acid, followed by metal impregnation at 0%, 1%, 3%, and 5% w/w, and calcination at 500oC for 2, 4, and 6 hours, respectively. It is then oxidized at 400oC for 2 hours and reduced at 400oC for 2 hours. The catalyst's crystallinity, morphology, and metal distribution are determined through X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) analysis. The catalyst with the best crystallinity and metal distribution is found to have 3% metal loading and a calcination time of 2 hours.
