| Abstract | The use of waste hotfluid from a condensate pot in ageothermal steam pipe line for the extraction essential oil is studied in this paper. The aim of this study is to replace the current fuel by a non CO2 producing geothermal energy source in producing essential oil from the Vetiveria zizanoides root (Akar Wangi) which is abundant near the condensate pot’s fluid location, in West Java, Indonesia. The accumulation of condensate from a typical steam main pipe line amounts to about 58.4 tons/day with a temperature of 200 degC, while the essential oil extraction process needs steam of at least 110 degC (usually from fired boiler) with a steam rate of 2 kg/hour/kg of dry Vetiveria zizanoides roots (Suwarda, 2009). The plan is to use condensate collected from condensate pot in a heat exchanger to produce steam at 143.6 degC and 4 bara to extract essential oil. It is found that the system proposed in this study will be able to produce about 3.77 kg of Vetiveria zizanoides essential oil per day, with 15 hours required for condensate accumulation from the condensate pot and 9 hours for the extraction process. |
