RANCANG BANGUN DAN UJI KINERJA KONDENSOR TIPE PIPA 12U DENGAN VARIASI JUMLAH BARIS PIPA TERHADAP PRODUKSI MINYAK GASIFIKASI

Abstract

Coconut shell is one of the most common biomass fuels found in Indonesia. So far the processing of coconut shell waste has only been burned directly to make charcoal and this has actually created a new problem, namely air pollution. Another way that is environmentally friendly is the gasification process. Gasification is a process of converting solid fuel into combustible gas (CO, CH4, H2). To make oil, the smoke from gasification needs to be cooled using a device called a condenser. The performance of the condenser itself is influenced by several things, including: condenser design, material conductivity value, operating environment temperature, type of cooling fluid, and direction of fluid flow. The choice of the geometric shape of a condenser will affect the heat transfer process that occurs in the condenser. This type of research is experimental research with descriptive quantitative data analysis, namely by looking for the effect of variations in the number of lines of condenser pipes with a number of lines 3, number of lines 4, and number of lines 5 in order to determine the value of the effectiveness of the condenser and the quantity of oil. Data collection is done by recording the temperature of the cooling fluid and gas entering and leaving the condenser and then comparing the amount of oil produced. The data is then displayed in graphs and described in sentences that are easy to understand. The highest quantity of oil produced is in variation 3 with the number of rows 5 as much as 274 grams, then for variation 2 as much as 250 grams and for variation 1 as much as 224 grams. For the highest effectiveness of the condenser is found in variation 3 with an effectiveness value of 80% then for variation 2 it is 78% and variation 1 is 73%. While the highest gasification efficiency value is in variation 1 with a value of 74%, for variation 2 is 64%, and the lowest is variation 3 with 61%. From the results obtained, it can be concluded that there is an influence on the addition of the number of lines on the production of gasified oil.
