Empirical Model for Heat Transfer of Electric Submersible Pump (ESP) Motor at Oil Producer Well Gunawan Gunawan; Idral Amri; Bahruddin Bahruddin
Journal of Earth Energy Engineering Vol. 8 No. 2 (2019): OCTOBER
Publisher : Universitas Islam Riau (UIR) Press

Motor operating temperature at wells equipped with Electric Submersible Pump (ESP) need to be monitored to maintain ESP performance run life. Not all producer wells equipped with temperature sensor, so it considered necessary to build mathematic model to estimate motor operating temperature. Model of heat transfer to predict motor operating temperature is developed based on empirical equation method. Parameter and variable data obtained from producer wells include water cut, viscosity, specific gravity, operating temperature, ampere and voltage. Procedure to calculate viscosity is ASTM D-88 and procedure to calculate specific gravity is ASTM D-5002. From 18 wells data obtained from the field, calculated reynolds numbers indicate turbulent flow regime with reynold numbers more than 4,000. Nusselt number were calculated using multiple linear regression with result of Nu = 0.06 * Re0.65 * Pr0.36 with error of 1.3% from downhole sensor measurement. The comparison with similar research also provided that use different Nusselt number empirical equation. The conclusion from the research showing that empirical approach by using specific constants to predict Nusselt number can be used to predict more accurate heat transfer coefficient with error 1.3%. Higher water cut fluid flow need lower fluid velocity to achieve motor operating temperature below motor limit temperature with fluid velocity above 0.3 m/s.

Karet alam dapat dimanfaatkan sebagai aditif aspal, baik dalam bentuk lateks, cup lump, dan karet padat (crumb rubber, block skim rubber, dan lain-lain). Penelitian ini bertujuan mempelajari pengaruh penambahan crepe rubber dan antioksidan 1,2-dihydro-2,2,4-trimethyl-quinoline (TMQ) terhadap karakteristik Marshall. Karet alam mentah dalam bentuk cup lump digiling menggunakan creeper hingga didapatkan crepe rubber dengan dry rubber content >95%, lalu dimastikasi menggunakan open mill. Selanjutnya, crepe rubber dilelehkan pada 200 °C sebelum dicampur dengan aspal pada 165 °C. Kadar crepe rubber dalam campuran aspal bervariasi, yaitu 8, 10, dan 12% (b/b). Selama proses pencampuran ditambahkan antioksidan TMQ dengan kadar 1%, 2%, 3% (b/b). Sampel aspal karet diuji karakteristik Marshall sesuai ASTM D6927. Hasil pengujian menunjukkan penambahan crepe rubber meningkatkan stabilitas aspal dalam menahan beban. Hasil optimum diperoleh dengan perlakuan 10% crepe rubber, 2% TMQ, dan 5,50% aspal, dimana memiliki stabilitas Marshall 1.403,96 kg, VFA 75,90%, VIM 3,07%, VMA 15,34%, flow 3,370 mm, dan MQ 416,605 kg/mm.

Contemporarily, Indonesia and Malaysia are the largest contributors of crude palm oil (CPO) in the world by up to 40%, and 37.3%, respectively. Furthermore, its production value this year reached 19.7 million tons, where each generates 2.5 m3 of wastewater. Meanwhile, of all the provinces in Indonesia specifically, Riau is the largest supplier for exports by up to 38%, generated from 225 palm oil mills, where a total of 6.3 million tons resulting in the generation of about 15.75 million m3 of wastewater, with organic content between the range of 30,000-60,000 mg COD/l. In addition, one of the uses of this wastewater includes anaerobic processes, with the double benefit of reducing COD concentrations, subsequently applying it as fertilizer, and also in the production of methane gas, as an alternative source of energy. The purpose of this study, therefore, is to observe the effect of bioreactor volume, scale-up on the performance of anaerobic hybrid bioreactors, in the treatment of mill effluents. The technology examined in this study was the anaerobic hybrid bioreactor with the dimensions of length 22 m, width 10 m, and depth 1.5 m, and a total volume of 330 m3, which is impermeable to oxygen, and a 250 m3 effective working volume. This was built and operated at a hydraulic retention time of 1 day, in the Palm Oil Mill of Riau, and the results showed the environmental conditions to range from a pH of 7.2 to 8.0, with temperatures from 320C to 350C, acetic acid of 774 mg/l to 1,180 mg/l, and alkalinity of 2,149 mg/l up to 2,400 mg/l. Furthermore, the performance of these reactors are shown by the highest COD removal efficiency of 77.8%, and a biogas test for the propensity of being applied as an alternative energy source obtained a methane gas concentration of 54%.

Until 2009, Riau Province had lost more than four million hectares of forest. The loss of forest coverage was caused by several reasons, such as forest area converted into oil palm plantation (29%), converted into industrial forest (24%) and abandoned deforested land (17%) which was not replaced by any other plants. Up until 2016, Riau Province ranked first in oil palm plantation development with area of 2,430,508 hectares and total of 534,827 workers. The largest amount of replanting activity waste came from oil palm trunks. The treatments of oil palm trunks waste by burning as well as decomposing were considered wasteful and costly. This also leads to a massive carbon emission in the atmosphere, which would cause global warming. Currently, CO2 gas concentration is 40% higher compared to pre-industrial era mainly due to fossil fuel incineration and deforestation. This research aims to measure the dry weight and the amount of carbon and carbon dioxide stock within oil palm trunks waste, as a consideration in taking a policy on preventing and or reducing carbon released to the atmosphere. Oil palm trunks waste came from PT. Perkebunan Nusantara V Persero (state-owned) plantation in Tandum, Riau Province. Data for measuring dry weight and the amount of carbon and carbon dioxide stock was taken randomly from three oil palm trunks. Every trunk was divided into three part (lumbers) which represent the base, middle, and top part of the trunk. Based on the research result, the weight of dry oil palm trunks averages 394.11 kg/tree or 50.45 ton/ha. Carbon stock on oil palm’s biomass averaging at 223.68 kg C/tree or 28.63 ton C/ha, equivalent to 104.97 ton CO2/ha of carbon dioxide stock. The dry weight and the amount of carbon and carbon dioxide in base trunk part are higher than the middle, and the middle part was higher than the top. This data indicates that the base part of the trunk contain the highest amount of biomass and carbon and carbon dioxide stock.

Industri pulp di Riau menghasilkan 8,5 juta ton black liquor/tahun, merupakan biomassa dengan panas pembakaran 13,8 MJ/kg sehingga memiliki potensi untuk digunakan sebagai sumber energi alternatif dan terbarukan. Salah satu teknologi pengolahan black liquor adalah proses gasifikasi yang dapat menghasilkan gas bakar tipe medium. Penelitian ini mempelajari faktor-faktor yang mempengaruhi proses gasifikasi black liquor menjadi gas sintesis, dengan melakukan simulasi proses dalam entrained flow gasifier menggunakan agen gasifikasi oksigen. Beberapa tahap yang dipergunakan untuk menunjukkan seluruh proses gasifikasi, yaitu dekomposisi/pirolisis black liquor, pembakaran zat volatile, gasifikasi arang/char dan pemisahan gas-padatan. Umpan black liquor yang digunakan dengan nilai ultimate (basis kering): 34,0% C; 3,2% H; 4,8% S; 35,8% O, 18,2% Na; 3,1% K; 0,1% N; dan nilai proksimat (basis kering): kadar air 19,3%; zat volatile 38,3%, fixed carbon 11,8%; abu 30,6%. Variabel penelitian: temperatur 600-1200oC, ER 0,2-0,5 dan tekanan 1-35 atm. Pada tekanan 10 atm dan ER 0,5, peningkatan temperatur 600 sampai 1200oC menyebabkan produk syngas bertambah (41,21-81,45%), mengurangi konversi CH4 (8,96-6,04%) dan CO2 (9,28-3,79%). Equivalent ratio berpengaruh terhadap temperatur proses gasifikasi, optimal antara 0,5. Menaikkan tekanan operasi gasifier tidak terlalu berpengaruh terhadap produk komposisi syngas, tetapi desain tekanan tinggi operasi untuk mempertimbangkan penggunaan alat yang lebih efektif dan efisien sehingga akan mengurangi biaya investasi, tekanan optimal adalah 10 atm.
