Abstract

Climate change is a major issue that is very interesting to discuss. Climate change is believed to be caused by the greenhouse gas effect. CO2 is one of the gases that causes the greenhouse gas effect. Therefore, to avoid the dangers of climate change, reducing CO2 emissions is the main topic in various articles. In this article, CO2 emission mitigation is analyzed in the sea water desalination plant using reverse electrodialysis power generation. Reverse electrodialysis is a power plant that does not produce CO2 emissions which converts energy from the difference in salinity of two solutions into electrical energy through selective ion membrane technology. There are 8 sea water desalination (SWD) unit which produces 242 tons/h of clean water for industrial activity and blowdown water of 3,161 tons/h, the blowdown water is wastewater. The SWD unit requires 3.043 tons/h of seawater as feed water, 0.164 MW of electricity and 86 tons/h of steam worth 64.1 MW as an energy. The energy are met from the combined heat and power operation. Combined heat and power require of fuel oil and fuel gas which produce CO2 emissions of 1,352,445,626 kgCO2/y. From the analysis on the SWD plant, the CO2 emission is 148,411,874 kgCO2/y. By implementing reverse electrodialysis power generation, blowdown water at the SWD plant which has a salinity concentration of 680 mol/m3 can produce electricity of 0.414 MW (3,636 MWh/y). If the electricity generated is used to substitute the electricity needs at the refinery plant, the CO2 emissions that can be mitigated is 2,955,915 kgCO2/y

Abstract

Well “X” merupakan salah satu sumur produksi panas bumi yang memproduksikan fluida dua fasa yaitu uap dan brine. Brine inilah yang biasanya membawa zat-zat yang dapat membentuk scale seperti Silica, Calcite dan Sulphide. Scale pada sumur produksi dapat mengurangi produksi secara signifikan karena mampu menghambat aliran fluida di dalam sumur. Hal itulah yang terjadi pada Well “X”. Parameter terpenting dalam pembentukan scale adalah Scale Saturation Index (SSI). Bila SSI > 1, maka fluida dalam kondisi supersaturated dan pengendapan silica dimungkinkan terbentuk. Pembentukan scale akan meningkat seiring dengan penurunan temperatur dan kenaikan pH akibat flashing. Sehingga laju pembentukan scale dan lama waktu pembentukan scale dapat dihitung secara matematis. Data yang diperlukan dalam analisa ini adalah data hasil produksi Well “X” (Output Curve) dan data sampel scale Well “X”. Untuk menghitung SSI dilakukan perbandingan antara konsentrasi silica dalam larutan dengan kelarutan amorphous silica pada kondisi yang sama. Sedang kan untuk menghitung laju pembentukan scale dan lama waktu pembentukan scale adalah densitas silica, kelarutan quartz pada temperatur reservoir, larutan amorf pada temperatur flashing dan salinitas. Dari hasil analisa yang dilakukan didapatkan bahwa endapan silika tidak akan terbentuk pada WHP yang telah digunakan. Apabila dilakukan analisa Trial and Error diantara didapatkan bahwa nilai SSI ? 1 berada pada tekanan 2.3 bar a atau 18.08 psia. fgSedangkan untuk analisa laju dan lama waktu pembentukan scale, pada tekanan WHP 7.81 bar a atau 114.64 psig merupakan yang paling baik karena laju pembentukan scale yang tidak terlalu besar yaitu sekitar 1.56 inch/ tahun dan waktu pembentukan scale sebesar 25% adalah yang lebih lama yaitu 1.12321 tahun.

Abstract

The growing demand for LPG has increased the number of LPG tanker ships/gas carriers entering X Port, resulting in queues that will impede the distribution of LPG to the people of Belitung Island. PT XYZ in-tends to construct an LPG tank in the X Port area to facilitate LPG distribution on Belitung Island. The tank capacity is expected to meet Belitung Island’s LPG demand for the next five years. The authors forecast the potential demand for the next five years using LPG revenue data from January 2019 to February 2021, with forecasting results from March 2021 to February 2026. The Time Series Method was used to forecast by comparing the smallest MAD (Mean Absolute Deviation) values between the Linear Trend Model and the Exponential Trend Model. According to the forecasting calculations conducted using the linear trend mod-el, the potential demand for February 2026 is 973.4098 Tons with a ten-day stock resistance. According to these calculations, the proposed tank is a spherical tank with a capacity of 1000 tons, which means that the LPG tank stock resistance in the last period, namely February 2026, is 11 days, which is in compliance with the Regulation of the Ministry of Energy and Mineral Resources Number 26 of 2009 concerning the Provision and Distribution of Liquefied Petroleum Gas.

Abstract

The XY Field is an oil field in the Sunda Basin which was developed since 1981 and has been produced in the Baturaja carbonate layer and Talang Akar sandstone layer. Decreasing the amount of oil production in the reservoir can have a detrimental impact on the company so it is necessary to analyze the remaining reserves of the reservoir. The calculation used to evaluate the remaining reserves use the Volumetric, Material Balance and Decline Curve methods. From the three methods, the results that are close to the reserve of the XY field reservoir are 14 MMSTB. OOIP is obtained from the volumetric method and material balance which is divided into P10, P50 and P90. The reserve OOIP for P10 is 110.8 MMSTB and P90 is 60.34 MMSTB, with the last cumulative production in December 2019 being 9.3 MMSTB, where the economic limit of the field is 46 bbl. / day and the contract will be expired in 2038. From the results of the subsurface analysis, the four infill wells are candidates for infill wells because they have hydrocarbon potential. Then in terms of economics this development scenario is feasible to be developed with NPV reaching 9,140 MUSD, the ROR reaching 41% for PSC and 60% for Gross Split, and increases field recovery factor (RF) up to 56%.
