Abstract

Biogas from Palm Oil Mill Effluent (POME) is one of renewable energy resources that can be used to reduce theuse of fossil energy in satisfying the electricity needs. At biogas power plant, gas engine is an importantcomponent which functions to convert the energy contained biogas into mechanical energy to drive the electricgenerator. Because of its important function, the performance of the gas engine needs to be maintained in orderto remain well operated. In addition to maintaining the performance of gas engine, steps in improving theefficiency of gas engine energy usage also need to be done in order to become more efficient. Efficiency of thegas engine depends on the overall efficiency of cylinders gas engine in order to convert the energy of fuel intowork. Energy analysis is needed to know the efficiency of multi-cylinder gas engine at biogas power plant, so itcan be known the gas engine performance and can be used for further analysis in increasing the efficiency of theuse of renewable energy sources (biogas) in gas engine. The purpose of this research was to know the energy orthermal efficiency of gas engine. Variables used in the analysis were a composition of biogas, flow rate ofbiogas, a temperature of gas mixture entering the gas engine and temperature of exhaust gas. The energyanalysis result showed that the efficiency of all cylinders varies and the greatest energy or thermal efficiency ofgas engine is on 5th and 10th cylinder (56.29%) and lowest in 8th cylinder (56.17%). The average energy orthermal efficiency of gas engine is 56.23%.Keyword : Biogas, Biogas Power Plant, Gas Engine, Otto Cycle, Energy Analysis

Abstract

Adsorption on a solid adsorbent is the fundamental processes in the field of separation processes, purification of gases, adsorption cooling, advanced adsorption cooling, and extensive work on hydrogen storage. The understanding of the thermodynamic properties of adsorbent plus adsorbate system is important to analyze. Information concerning the relevant adsorption equilibrium and characterized of adsorbent is generally an essential requirement for the analysis and design of an adsorption separation process. For practical application, theadsorption equilibrium must be known over a broad range of operation temperatures. Also, the isotherms of pure species are fundamental information for dynamic simulation of adsorbers. The main objective of this research is to design kinetic adsorption test rig to investigate the capacity and rate of adsorption on adsorbent and adsorbate pair’s. The result of design kinetic adsorption test rig including dimensions of vapor vessel (pressure vessel) and measuring cell. The volume of vapour vessel is 1000 ml and measuring cell is 100 ml. Kinetic adsorption test rig was manufactured to investigate capacity and rate of adsorption up to 40 bar.

Abstract

Sistem adsorbed natural gas (ANG) adalah metode distribusi bahan bakar gas yang lebih baik dibandingkan dengan menggunakan compressed natural gas (CNG) hal tersebut dikarenakan ANG menggunakan sistem penyerapan (adsorption system) yang hanya membutuhkan tekananpenyimpanan sekitar 4 MPa. Pada rancangan untuk aplikasi sistem adsorpsi seperti pada penyimpanan gas alam, disamping data karakteristik adsorben seperti luas permukaan dan volume pori, data penyerapan adsorbat pada adsorben juga dibutuhkan. Penelitian ini dilakukan untuk mendapatkan data kapasitas penyerapan CH4 pada karbon aktif sebagai adsorben dengan menggunakan metode volumetrik pada tekanan sampai dengan 3,5 MPa dan pada temperatur 27oC,35oC dan 65oC. Kapasitas penyerapan maksimum pada karbon aktif KT adalah 0.05138 kg/kg pada temperatur 27oC dan tekanan equilibrium 3495,75 kPa. Data eksperimen dianalisis dengan menggunakan model Langmuir dan Toth. Hasil regresi data eksperimen dengan menggunakanmodel Langmuir dan Toth adalah 3,45% dan 2,72% untuk karbon aktif komersial dan 3,95% dan 2,78% untuk karbon aktif KT.

Abstract

The increasing consumption of fossil fuels as energy source of the world cause a decrease in a number of fossil fuels. Wind energy as one of renewable energy resource has a great potential to solve the problem of dependency on fossil fuels, especially in Pekanbaru, Indonesia. Pekanbaru wind speed condition which is considered relatively low can be harnessed efficiently by designing blades which suits wind characteristics in Pekanbaru.  Blades are designed using aerodynamic equations and  software assistance such as Microsoft Excel, Qblade, and Autodesk Inventor. As a result, the blades had a solid structure, easily in manufacturing and affordable which can generate mechanical power at low wind speeds with a radius 1,1 m and hub 0,2 m and the chord length  at the base of  the blade 0,13 m and at the tip 0,26 with twist angle at the base of the blade 20,4  and at the tip 5,6  . The result of this research is to show that the inverse taper blade design is applicable in low wind speed conditions in order to produce an affordable, compact, and efficient wind turbine appropriate for wind characteristic in Pekanbaru. Keyword : Chord, Twist Angle, Blades, Inverse Taper, Wind Turbine

Abstract

Waste heat from industries such as steam power plants can be utilized to meet the world’s electricity need. However, it cannot be converted efficiently to electric power by using conventional power generation methods, a technology for converting it is called Organic Rankine Cycle (ORC). ORC is one of the power plant systems that is a modification of Rankine Cycle using organic working fluid. R-134a was used as working fluid. The selection of working fluid was assisted by using Cycle Tempo and REFPROP software which has function to simulation of power plant and determine the thermodynamic properties, respectively. ORC system consisting of four key components: evaporator, turbine, condenser, and pump. In this study, we designed a shell and tube type evaporator, where it is designed from a large cylindrical tube called a shell assembled with a parallel pipe. Flow arrangement of evaporator is parallel-flow. Design of evaporator was 400mm shell length, 360mm shell diameter, 9.525mm OD tube, 8.407mm ID tube, tube length 10.57m, 250mm helical tube diameter, 300mm helical tube height and 13.5 the revolution of tube.Keywords: Organic Rankine Cycle, Design, Manufacturing, R-134a
