Abstract

Emission gas reducer on motor vehicle, automobile, light engine of boat and stationary combustion engine. The use of motor vehicle should be followed by protection against damages on the environment, since the exhaust gas from combustion engine has significantly affect on air and environmental pollution. One method to solve the problems in air pollution has been done by using a re-heater designed in Mechanical Engineering Department, University of Udayana. In accordance to the test on the re-heater, it can be seen very clear that the re-heater has significantly reduce the CO emission of about 54%. It also reduces the CO2 dan HC emission, and in the other side increases the number of O2. The re-heater has no significant effect to engine performance during the operation and also reduces the noise of motor.

Abstract

Penambahan sistem SRO pada Pembangkit Listrik Tenaga Diesel Gas merupakan salah satu upaya untuk memanfaatkan panas sisa dari gas buang mesin diesel. Analisis penambahan sistem SRO ini dilakukan dalam simulasi menggunakan software Aspen Plus®. Model yang digunakan dalam SRO ini adalah SRO sederhana, SRO WHRPG, dan SRO dengan recuperator. Penambahan SRO diharapkan mampu meningkatkan energi listrik yang dihasilkan, efisiensi, dan menurunkan temperatur gas buang mesin diesel. Kinerja sistem dianalisis untuk keseimbangan energi dan eksergi. Pada penelitian ini didapatkan peningkatan performa pada PLTDG setelah dikombinasikan dengan SRO WHRPG. Daya listrik yang dihasilkan adalah 15.158,07 kW dengan efisiensi energi sebesar 36,35% dan efisiensi eksergi sebesar 33,17%. Dengan penambahan WHRPG SRO juga dapat menurunkan temperatur gas buang hingga 532,14 K. The addition of an SRO system in a diesel-gas power plant is one of the efforts to utilize the residual heat from diesel engine exhaust gas. The analysis of the addition of this SRO system was carried out in a simulation using the Aspen Plus® software. The models used in this SRO are simple SRO, WHRPG SRO, and SRO with recuperator. The addition of SRO is expected that it can increase the electrical energy generated, efficiency, and reduce the diesel engine exhaust gas temperature. The system performance will be analysed for energy balance and eksergi. In this study, the performance of diesel-gas power plant increased after it was combined with WHRPG SRO. The electrical power produced is 15,158.07 kW with an energy efficiency of 36.35% and an eksergi efficiency of 33.17%. With the addition of WHRPG SRO, it can also reduce the exhaust gas temperature up to 532.14 K.
