Pengaruh Luas Perpindahan Panas Kondensor Terhadap Volume Asap Cair Terkondensasi Hasil Pirolisis Tempurung Kelapa

Abstract

One of the products that can be made from coconut shell is to make charcoal by pyrolysis. Pyrolysis also produces liquid smoke, tar, and uncondensed gasses. Liquid smoke is a byproduct of the activated charcoal industry which has high economic value. Liquid smoke is a substance derived from the change of state into the coolant fumes which involves the heat transfer. Liquid smoke is obtained simultaneously with the production of charcoal (carbonization) and the smoke from incomplete combustion. The purposes of this study were to determine the heat transfer surface area (A) in the manufacture of liquid smoke and the relationship between heat transfer surface area (A) and the liquid smoke volume. The stages of the study consist of designing of equipment, burning of coconut shell and measuring the volume of liquid smoke. The results showed that the highest liquid smoke volume of 215 mL was obtained on the weight of coconut shell of 8 kg and condenser of 8 pipes with a pyrolysis time of 90 minutes and the theory of heat transfer surface area of 0.076965 m 2 .
