Abstract

This study aims to conduct a Remaining Life Assessment (RLA) on the shell 1st stage separator. The process is carried out through the stages of calculating the minimum permissible shell thickness, MAWP, corrosion rate, and determining the operational feasibility of the separator. The method used is non-destructive test (NDT) inspection to determine the minimum actual thickness. Calculations were made using the API 510 standard. Based on the evaluation of the minimum thickness and MAWP value, the 1st separator shell is still feasible to operate. The ST corrosion rate that occurred in 2012, 2016, and 2019 was 0.123 mm/year, respectively; 0.007 mm/year; and 0.023 mm/year. While the LT corrosion rate is 0.089 mm/year, RLA analysis shows that the remaining life in 2012 was 93.75 years, 93.42 years in 2016, and 92.63 years in 2019. Thus, the shell 1st stage separator is still feasible to operate.

Abstract

Biogas is a raw material utilized to produced biogas. Biogas is renewable energy source produced by the anaerobic activity of organic matter through the fermentation process. Quality of biogas is determined by its main composition, such as methane (CH4). In addition, the composition of biogas also contains impurities such as unburnt carbon dioxide (CO2) so that it reduces the heating value, hydrogen sulfide (H2S) and water vapor (H2O) which are corrosive as well as Nitrogen (N2). Adsorption method on the impurity compositions can be used to improve biogas quality. This research used a column purifier containing four adsorbents in the form of calcium hydroxide Ca(OH)2, iron gram (Fe2(O3)), zeolite and activated carbon with three volume variations 600 cm3, 900 cm3 and 1200 cm3. The results of biogas testing using gas chromatography showed that the best quality obtained from the 1200 cm3 volume of adsorbent. Methane content was increased up to 17.985% and the impurity gases were decreased, such as carbon dioxide in as much as 18.15%, hydrogen sulfide and water vapor in as much as 0.182%. The heat produced by unpurified biogas was 1518.312 kJ/m3 and the highest heating value after purification was 2108.22 kJ/m3. The biogas combustion resulted in a dominant blue flame color.The most optimum effectiveness of the technology resulted in an increase of the methane content up to 64.275%. Based on this research, the utilization of column purifier with the adsorption method was able to improve the quality of biogas

Abstract

Mikrostrukur sangat berpengaruh terhadap karakteristik material. Penelitian ini dilakukan dengan tujuan untuk mengetahui tingkat kekerasan makro pada kepala rel kereta api tipe R54 yang digunakan di tanjung karang. Pengujain yang dilakukan meliputi pengujian kekerasan dengan menggunkan metode vickers dengan menggunakan Universal Hardness Tester. Hasil pengujian kekersan pada bagian kepala yang rel yang dilakukan dengan tiga kali pengujian dimana dua pengujian dilakukan pada spesimen A dan satu pengujian dilakukan di spesimen B. pengujian pada spesimen A yang diambil secara vertikal memiliki nilai rata-rata 347,31 HVN dan pengujian yang diambil secara horizontal memiliki nilai rata-rata 354,077 HVN. Sementara pengujian yang dilakukan pada spesimen B yang berupa potongan dari bagian kepala rel memiliki nilai kekerasan rata-rata 362,60 HVN.
