Abstract

The utilization of old gas wells in Balun field has the potential to improve the welfare of the people in Cepu District and the surrounding areas in meeting their daily gas needs. However, the challenge of these old unutilized gas wells has risks and impacts on the environment, such as the possibility of gas leak causing fires. This study aimed to analyze the potential of old gas wells and to analyze the impact of risks on the areas around the old gas wells, which will be passed through the gas network, and where the gas processing units will be established. In this analysis, the results of the gas processing process would be distributed to Cepu District to meet household fuel needs. In addition, the use of these old gas wells is also to provide education to students regarding gas processing and distribution. The analysis of the utilization of old gas wells began with mapping of environmental conditions, distribution pipeline systems, and gas processing locations. The mechanical equipment requirements for the model, pipeline design, and processing unit would be presented. Next, the need for the instrumentation system would improve the transmission system and processing unit with reference to ease of operation and safety. In addition, budget requirements and flow diagram were needed to facilitate further programs when building pipelines and the desired gas processing unit

Abstract

Komposit magnetoelektrik (ME) terdiri dari lapisan piezoelektrik dan lapisan magnetoelektrik yang disusun secara bergantian. Masalah yang paling sering ditemukan pada hasil deposisi thin film aluminium nitrida (AlN) sebagai lapisan piezoelektrik adalah residual stress. Riset ini bertujuan untuk mengoptimalkan parameter deposisi AlN dalam menghasilkan film AlN dengan residual stress yang mendekati nol tanpa mengorbankan sifat mikrostruktural dan respon piezoelektrik. Pengaruh waktu pra-etching dan ketebalan film AlN pada residual stress, mikrostruktural, dan respon piezoelektrik telah dipelajari, masing-masing melalui dengan stylus profilometer, difraktometri sinar-X, dan metode 4-point bending. Urutan lapisan film yang dideposisikan pada substrat Si/SiO2 adalah Ta/Pt/AlN. Metode pulsed DC reactive sputter telah dilakukan untuk mendeposisikan film AlN. Pengaruh waktu pra-etching pada residual stress AlN tidak menunjukkan perubahan yang signifikan. Nilai residual stress dari film AlN semakin rendah dengan meningkatkan ketebalan film akibat dari peningkatan arah tumbuh preferensial dari kristal AlN. FWHM dari puncak AlN (0002) hampir konstan dalam rentang waktu pra-etching. Dengan meningkatnya ketebalan film, penurunan FWHM dikaitkan dengan pertumbuhan kristal berbentuk kolom yang lebih baik. Hal ini juga menghasilkan magnitudo dari nilai e31, f yang lebih tinggi.

Abstract

Storage tank adalah peralatan penting dalam industri minyak dan gas (migas), khususnya pada penerimaan, penimbunan dan pendistribusian minyak dan gas. PT. X sebagai pengolahan migas gas terbesar di Provinsi Kalimantan Timur terus meningkatkan kualitas pengolahan migas. Dalam hal ini, kapasitas dan kualitas dari storage tank sebagai salah satu komponen penting pada kegiatan pengolahan migas juga harus ditingkatkan. Sejak tahun 2018, PT. X yang bekerja sama dengan PT. Y melakukan perbaikan dan perancangan ulang storage tank. Proses perancangan storage tank harus mempertimbangkan perhitungan yang mencakup dimensi shell plate, annular bottom dan roof dengan one-foot method. Selain itu, perhitungan mencakup perhitungan juga meliputi terhadap kekuatan angin dan stabilitas yang mengacu pada API 650 Edisi ke-12 Adendum 3, Agustus 2018. Storage tank P–7 merupakan tank yang menyimpan product light slop oil dengan kapasitas 5654 m3, diameter 24 m, tinggi 12,5 m, jumlah shell course sebanyak 7 course, dan jenis internal floating roof yang termasuk scope of work perancangan ulang kontraktor dengan bantuan software AMETank 7.7 Tahun 2014. Dari hasil perhitungan, perancangan internal floating roof storage tank menghasilkan thickness shell course 1 sebesar 9 mm dan thickness terbesar terdapat di annular plate yaitu 10 mm.
Perancangan Sistem Perpipaan untuk Fluida Mogas Dari Tangki TK0305 ke Pipa Header Suction Pompa 33LP0001 Hafid Suharyadi; Ahmad Jalaluddin Dulfi; Toegas Soegeng Soegiarto; Alfito Husni Zulfaqar

Abstract

Sistem perpipaan merupakan peralatan untuk mengalirkan fluida dari satu peralatan ke perelatan lainnya. PT Jakarta Tank Terminal (JTT) yang bergerak dibidang jasa penyimpanan produk memiliki banyak sistem perpipaan yang digunakan untuk mengalirkan produk dari tangki timbun ke mobil tangki. JTT akan melakukan pengembangan phase 2B yaitu pembangunan tangki timbun TK0305 dan sistem perpipaan sampai ke pipa header suction pompa 33LP0001 sepanjang 162 m pada area tank farm 3 dengan mengalirkan mogas ke truck loading bay menggunakan kapasitas alir 750 m3/h. Sistem perpipaan harus dirancang dengan aman sesuai dengan kondisi operasi yang mengacu pada standar ASME B31.3, sehingga kebocoran dan biaya berlebih pada pembangunan sistem perpipaan tersebut dapat dihindari. Dari hasil analisis didapatkan diameter nominal pipa sebesar 14 inchi. Material pipa yang dipilih ASTM A53 Grade B. Wall Thickness yang dipilih yaitu 0,375 inchi (SCH 30 ST) yang mampu mengakomodir corrosion allowance 0,0591 inchi. Jarak Support maksimum yang didapatkan yaitu 13,526 m karena aman terhadap defleksi maupun tegangan. Pada perancangan sistem perpipaan untuk mogas ini dengan parameter dan jalur pipa yang direncanakan fleksibilitasnya terpenuhi. Analisa stress sistem perpipaan ini dilakukan dengan menggunakan aplikasi Caesar II dengan pembebanan sustain, expantion, operational dan Hydrotest didapatkan hasil tegangan tidak melebihi allowable stress material pipa yaitu 30.000 psi sehingga aman dioperasikan.

Abstract

This research aims to analyze the performance of the ML45 Screw compressor based on field observation data. Based on the observation and data analysis, several conclusions can be drawn. First, the actual capacity of the compressor decreased by about 33.12% from 100% initial condition of 261.22 CFM to 66.87% of 174.7 CFM. This decrease is due to the difference in operational pressure which is lower than the design pressure. Secondly, the power generated by the current compressor is about 31.6 KW, which is lower than the design power of 45 KW. This decrease in power is due to the low input temperature. These findings indicate the importance of considering actual operational conditions in optimizing compressor performance. In this context, further adjustments or evaluations are recommended to ensure optimal performance of the ML45 Screw compressor. Factors such as operational pressure and input temperature should be carefully considered to achieve the expected results. This research provides valuable insights for the industry in understanding the factors affecting compressor performance and provides a basis for future performance improvements. These efforts are expected to improve operational efficiency and reduce potential losses in the use of Screw ML45 compressors.

Abstract

The wear and deformation of critical components in centrifugal pumps, such as wear-casing rings, can be caused by the influence of operational lifetime and varying boundary conditions. To enhance the accuracy of wear and deformation predictions, this study integrates finite element analysis (FEA) with detailed field measurement data, including material wear rates and load conditions. The boundary conditions were applied to the CAD model of the wear-casing ring under varying operational loads. The simulation results indicate that the wear casing ring experiences a maximum deformation of 0.0037545 mm, with an estimated lifespan of 5.571 × 10⁷ cycles under normal loading and 0.5517 × 10⁷ cycles under doubled loading conditions. The installation clearance of the wear casing ring is 0.38 mm, with a tolerance of 0.05 mm. The deformation results fell within the acceptable limits for continued use, meeting the clearance standard. The contributions of this study lie in providing more precise wear predictions and insights into wear ring performance and an applicable predictive maintenance method that can be used to improve pump reliability and reduce maintenance costs.
