Abstract

Aluminium composite 2075 manufacturing required a strenghthener such as bottom ash which has been through the electroless plating process that serves coating the bottom ash and sticks to aluminium casting process. The oxidation of 100oC produce 0,0126 µm Mg thickness oxidation, 200oC produce 0,0146 µm Mg thickness oxidation, and 300oC produces 0,0506 µm Mg thickness oxidation. Mechanical properties were tested by using worn-out test and hardness test based on new material function that will be used to replace existing disc brake material. Harness test showed that castings are using oxidized ash powder with higher temperature and produce resistant material than in low temperature. Casting mixture with oxidized bottom ash 100oC produce specific abrasion of 2,008 x 10-6 mm2/kg, produce of 1,814 x 10-6 mm2/kg for oxidized 200oC, and produce of 1,675 x 10-6 mm2/kg for oxidized 300oC.

Abstract

Increasing the need for pure hydrogen in the industry is growing. One of its roles is in purification of petroleum industry. High purity hydrogen (99.99%) was obtained from methane using the steam methane reforming method in the hydrogen plant unit. Hydrogen is a very dangerous chemical element with its flammable properties. This research is conducted especially on purification system. Quantitative analysis is used to determine the frequency of hydrogen leakage, consequence modeling, and risk estimation that will be generated. The results of the analysis show that the highest frequency occurs in unignited release events. The jet fire scenario produces the longest fire length in the HPU about 27 meters. The jet fire scenario impact produces the farthest secure distance in the case of a leak in the HPU section of 60 meters. The flash fire produces the farthest distance loss in a leakage case in the HPU of 80 meters, and explosion at a radius of 200 meters will have a blast overpressure 7.62 psig with 22% fatality estimation of the population.

Abstract

Corrosion that occurs in a gas flowline is a serious problem because it can cause leaks that lead to material loss and environmental pollution. The aims of this research were to analyze the corrosion occurred in gas flowline of carbon steel 5l Grade B and the effect of inhibitor TIC-8002 GCI to the corrosion rate of metal. This research was conducted using SEM-EDX to analyze and produce various types of metals and corrosion crust. Metals corrosion test and the effect of inhibitors on the corrosion rate of metals were carried out by linear polarization methods. The result of SEM-EDX showed that inner pipe surface occurred pitting corrosion caused by dissolved chloride ions in the electrolite that flows in the pipeline. The result of XRD showed that corrosion products of carbon steel were Fe2O3 and FeOOH. The result of linear polarization showed that the corrosion rate of steel about 0.642 mmy without using inhibitor. The addition of an inhibitor can reduce the corrosion rate in carbon steel. The increase in inhibitor concentration from 10 ppm to 50 ppm can reduce the corrosion rate from 0.633 mmy to 0.394 mmy along with an increase in inhibition efficiency from 1.32% to 38.6%.

Abstract

Silica scale formation on the brine re-injection lines of geothermal power plants can lead to serious problems because it increased pressure drop and failure of the safety devices. One of the most effective methods to solve the problem is acidification of silica scaling using hydroflouric acid (HF). HF has a unique characteristic that is highly reactive with SiO2, easily obtained in the market and cheap. The use of HF can increase the rate of material corrosion in re-injection lines material. The use of HF should be adjusted to the appropriate concentration so it can dissolve silica scale optimally without shortening its life service. The concentration of HF used in the experiment were 5, 10, and 15% wt. The results showed that the optimum concentration of HF in dissolving silica at 15%. This is due to its ability to dissolve the crust mostly greatest than most other concentration that is equal to 21% of the total dissolved silica. The rate of corrosion on the material re-injection line with a concentration of 15% is equal to 0.647 mm/y and provide about 4.63 years life time of pipe.

Abstract

The use of synthetic fibers in the fabrication of polymer composite materials has a negative impact on the environment. Natural fibers such as palm oil waste and banana pseudostem can be an alternative material for synthetic fibers because they are more economical, high specific strength, and environmentally friendly. The alkali treatment needs to be carried out on fibers for removal of lignin, hemicellulose, and impurity so that they can improve interfacial bonding between the fiber and the polymer matrix. The alkali treatment was carried out through fiber immersion in conditions without NaOH, 5% wt NaOH solution, and 10% wt for 24 hours. Fiber before and after alkalization were analyzed using Scanning Electron Microscope (SEM), X-Ray Difraction (XRD), Fourier Transform Infrared (FTIR), and Thermogravimetric  Analysis (TGA) methods. The results showed that alkali treatment was effective in removing the components of lignin, hemicellulose, and impurities in fiber. The result of the SEM was showed that the treated fiber surface has a cleaner surface than treatment without fiber. The alkali treatment process can improve the crystallinity and crystallinity index of the fiber due to amorphous component removal of lignin and hemicellulose. The TGA showed that palm oil fiber with alkali treatment and without alkali treatment a produced weight loss of 88,2% and 98,4% respectively. This showed that the alkali treatment can increase the thermal resistance of the palm oil fiber.
