Title

Coalbed Methane As a New Source of Energy in Indonesia and Some Developed Countries; A Review Hamdani Wahab; Mohammad Barbarosa; Awaludin Martin

The decrease in conventional energy sources followed by the world's energy demand as well as mounting concern about climate change, the countries are competing to get new sources of environmentally friendly energy with large reserves. The utilization of CBM as a new energy is an option because of its huge reserves, more environmentally friendly than traditional fossil energy (CBM emissions are 0.39 tones/MWh) and energy efficiency equivalent to natural gas. Indonesia has huge CBM reserves (400 TCF) but has not been utilize optimally due to technological problems, government regulations, large investments and others. This issues plus geographical constraints also occurs in countries with huge CBMs resource such as Russia (450 TCF) and China (700 TCF). Meanwhile, USA (500 TCF) and Australia (500 TCF) already have more established rules and technology. It is necessary to conduct a comparative study from each country according to the applicable regulations to accelerate the utilization of CBM.

Peatland fires are a problem every year in Indonesia especially in Sumatera Island. In Riau during the dry season, there will be peatland fires that are difficult to extinguish. There are several reasons for peatland fires and this study will analyze whether cigarette butts can cause peat fires or not. In this research peat sample was dried at 35-45°C and at temperature at 115°C to reduce water content in peat samples. Cigarette butts as a trigger were prepared with a length of 30 mm and tested on a bomb calorimeter to determine their calorific values. The cigarette butts with the highest HHV (High Heating Value) were used and burned on the surface of the peat sample by adding airflow to the sample with varying flow rates. The fastest of smoldering combustion propagation velocity was obtained 785 mm/hour for vertical direction and 1336 mm/hour for horizontal direction with speed of airflow of 5 m/s. The highest temperature was obtained in the experiment of 902°C with the speed of airflow of 5 m/s.

Analysis of Energy and Exergoeconomic on Water Cleaning and Injection Facilities in the CPP Block, Indonesia Hamdani Wahab; Awaludin Martin

One of the problems in the upstream oil and gas industry is that large quantities of produced water must go through a water cleaning and injection process in accordance with the Regulation of the State Minister of the Environment Number 19 of 2010 of the Republic of Indonesia concerning the quality standards of wastewater for oil and gas and geothermal activities. A total of 224,257.1 barrels of water per day which is produced water in the CPP Block must go through a water management process which requires a large energy consumption of 269.47 MW/month. One effort to reduce the use of electrical energy is to conduct energy and exergy analysis to determine the point of greatest energy use as a result of exergy destruction and convert it into economic costs as operating cost losses. From the research, it is known that the largest electrical energy consumption is at the injection pump 235.47 MW/month with exergy 67.72 KW, the largest exergy destruction is 31.04 KW at the charge filter pump with an efficiency of 54%. Energy and exergy analysis is used to identify changes in energy quality in a system.

BOB PT. Bumi Siak Pusako â€“ Pertamina Hulu is Indonesian Operator Company that uses gas power plant for Pekanbaru Coastal Plan (CPP) block. The 4x6 MW energy capacities must follow energy, exergy, economics analysis and environmental impacts due to COÂ² emission and exhaust gas temperature. From the analysis, the gas power plant thermal efficiency is 42.85%, exegetic efficiency is 33.22% with the largest exergy loss of 18.7 kW in combustion chamber, 7.1 kW in compressor, and 2.69 kW in gas turbine with total cost loss due to exergy destruction of 2,537.52 $/hour. The cost loss value is 1362.45 $/hour for compressor, 1,962.28 $/hour for combustion chamber, and 212.79 $/hour for gas turbine. The exhaust emission is 0.21 kg/s, forest area required to absorb pollution is 11.63 ha, exhaust heat released is 1913.51 kW. This study indicates that the analytical method carried out can be developed and applied comprehensively to generating facilities in Indonesia.

Indonesia is a maritime country that has an abundance of marine catches. In 2022, the production of marine catches reached 24.85 millions tons, while the export amount was 1.221 millions tons. This is due to the limited technology that can extend the freshness of marine catches. Based on this problem, a cooling system was designed in the form of an ABF that can freeze marine catch products. The Air Blast Freezing (ABF) system is designed at an air temperature of -40oC using a cascade refrigeration system. The working fluid used is R290/R32 hydrocarbon, which has very low GWP and ODP so it is safe for the environment and the earth's ozone layer. The results obtained show that the cooling load is 444.037 Watts, the LTC compressor power and HTC compressor power are 116.19 Watts and 205.98 watts. The designed air blast freezing system has a surface area of LTC evaporator of 2.670 m2 and HTC condenser of 4.780 m2. The calculated capillary pipe length is 1.94 m for HTC and 1.51 m for LTC, the COP of the ABF system is 2.774.

Freeze vacuum drying process is an optimum process to dry the product without changing the physical and chemical properties of materials. The advantages of drying with freeze vacuum drying are can be maintain the structures, nutrient, and colors of original substances. A weakness of freeze vacuum drying is its high consumption of energy due to the long drying time required especially in the process of sublimation below triple point condition. The aim of this research areto optimizing freeze vacuum drying in order to reducing energy consumption by utilized waste heat of condenser to speed up the sublimation process and by using quick drying method. Thefreezing temperatures in this study were 6° C and 9° C with a variation of the drying time is 1, 2 and 4 hours. This research was result the water content losses in yam bean are 78% at a freeze temperature -9° C with drying time 4 hours.
