Abstract

The well "ZL" is located in the Tarakan field which at the beginning of production did not use an Artificial Lift. However, these wells will experience a decrease in production rates due to lower reservoir pressure and increased water cut levels. An Artificial Lift is needed to help lift the fluid to the surface. The Artificial Lift chosen for the “ZL” well is the Electrical Submersible Pump. In the initial step of ESP design, the method used was appropriate to the field conditions "YY", namely the Vogel Method. Next determine the amount of pump efficiency (% EP) and perform optimization on the ESP pump by changing the operating frequency. The “ZL” well has a maximum flow rate of 3347.9 BFPD with a target flow rate of 2343.53 BFPD. Based on the target flow rate in the “ZL” well, it is recommended to use a REDA D2400N 60Hz pump. Furthermore, from the optimization results at a frequency of 50 Hz, a production rate of 1180.8 BFPD with 59% EP was obtained, at a frequency of 55 Hz, a production rate of 1659.6 BFPD with 66% EP was obtained, at a frequency of 60 Hz a production rate of 2346.8 BFPD was obtained with % EP 68%, at a frequency of 65 Hz the production rate was 2846.2 BFPD with% EP 64%, and at a frequency of 70 Hz the production rate was 3266.4 BFPD with% EP 60%. From the results obtained that the frequency of 60 Hz with a production rate of 2346.8 BFPD and% EP 68% were selected based on Best Efficiency.

Abstract

The process of liquefying natural gas to produce a product in the form of LPG (Liquefied Petroleum Gas) takes place at a very low temperature of -160ºC. Meanwhile, the gas feed contains a component in the form of carbon dioxide (CO₂) which has a freezing point of -56ºC. The CO₂ separation process is carried out in the CO₂ removal unit which consists of an absorber and an amine regenerator. In the absorber tower, there is a separation process of CO₂ gas components which will be separated by absorption by an amine solution. Amine flow must be adjusted to the flow feed gas that enters the absorber column so that there is no excess amine in the purification process, so the purpose of this study is to determine the maximum value of flow feed gas to get the optimal value of flow amine. The calculation method for finding the maximum flow amine uses trial and error calculations, where the value of the gas flow feed is varied. Based on research can be concluded that, by varying the increase in gas flow feed from 359 m³/h obtained the maximum value of gas flow feed which is 8195 m³/h which produces an optimal flow amine value of 1200,005 m³/h.

Abstract

Modeling of exhaust emissions (SO2) from refinery chimneys was carried out using the Gaussian Plume model through Screen3 software. The results showed that there was an influence of wind speed and atmospheric stability on the variation in modeling results. The higher the wind speed and the more stable an atmosphere, the lower the resulting concentration value. Modeling on the worst case scenario, produces the largest possible concentration value that might occur somewhere. The distribution map of the model results is displayed following the dominant wind direction, namely to the South and North of the refinery. The difference in the magnitude of the distribution of concentration values is depicted in the color difference. The more stable the conditions of atmospheric stability, the farther the high concentration will be from the refinery. The overall value of the model results shows a concentration value that is below the quality standard value when based on PP No. 41 of 1999. Mitigation of risk management includes regular training by industry and the government regarding air emissions and ambient air at refineries; through policies to eliminate the risk of industrial accidents.

Abstract

Kualitas bahan bakar Solar ditentukan oleh tinggi rendahnya Cetan Index atau Cetan Number, semakain tinggi kualitasnya akan semakin bagus. Mengingat saat ini penggunaan bahan bakar Solar semakin meningkat dikarenakan harganya lebih efisien, maka untuk menjaga agar tidak semakin meningkat pencemaran udara di sekitar kita akibat gas buang yang dihasilkan perlu ditingkatkan kualitas bahan bakar Solar yang mempunyai Angka Cetan 45 atau Cetan Number 48 yang biasa disebut Solar Subsidi tersebut. Penelitian dengan judul Analisa Blending Solar CN-48 dengan Pertadex CN-53 memiliki tujuan menghasilkan produk Solar CN-51 melalui proses blending dua komponen antara Solar CN-48 dengan Pertadex CN-53. Metode yang dilakukan dengan cara mencampurkan Solar CN-48 dengan Pertadex CN-53 dengan komposisi yang telah dihitung secara teori. Setelah dilakukan proses blending, maka dilakukan pengecekan Distilasi dengan menggunakan alat Distilasi ASTM D-86. Hasil yang diperoleh yaitu menghasilkan produk baru yang teruji secara spesifik, khususnya nilai Cetan. Nilai Cetan yang didapat merupakan hasil dari perhitungan (kalkulasi) matematis. Pengujian menggunakan instrument standard perlu dilakukan, namun secara laboratorium, pengujian yang telah dilakukan sesuai dengan prosedur dan teori yang berlaku. Peningkatan nilai Cetan dapat dengan melakukan pencampuran dua bahan dengan Cetan yang berbeda. Meskipun peningkatan nilai cetan tidak signifikan, dan hanya berada pada rentang dua bahan pencampuran, pada dasarnya proses tersebut telah merubah unsur-unsur mikroskopik pada bahan.

Abstract

Multiple in marine seismic data is the noise formed due to the high impedance contrast at the boundary between layer. Multiple interferes the data processing that will also affect the interpretation of subsurface image. The use of seismic reflection in ocean has become an activity that is often performed with a variety of purposes, to map the subsurface. The basic objective of seismic data processing is to convert the recorded information from the field into data that can be interpreted. One goal of seismic data processing is to eliminate or reduce the noise of reverberation and multiples as well as enhance the signal to noise ratio. The data are a 2D marine reflection seismic data with SEG-Y format that will be processed with using ProMAX software. SEG-Y data are combined with field geometry data in processing of header load, then is carried out noise reduction (trace editing and filtering), and seismic signal amplification (deconvolution and TAR).
