Abstract

In this paper, a plant for the extraction of essential oil from leaves of eucalyptus tree was developed. The extraction plant is made up of a steam generation unit (boiler), stripping chamber, condenser (heat exchanger), decanter (settler), cooling water system and a pressurized gas burner as heat source. The condenser, decanter, steam generation unit, stripping chamber, control valves and the cooling water system were sized and selected in such a way that the plant will perform to specification. The steam generation unit was designed to contain 25 litres of water with dimension 0.35m diameter by 0.26m high. The condenser has 24 tubes (i.e. 12 tubes per pass), its size is 1m long by 0.215m shell diameter. The stripping chamber was designed to process a maximum of 10kg of the raw material per batch run and its size is 0.35m diameter by 0.45m high while the cooling water system was specified as 200 litres capacity with O.SHP centrifugal pump to aid circulation of the cooling water. After the construction, the performance of the plant was evaluated and the following result was obtained: 18ml of eucalyptus oil only was realized at the end of the eighty - two (82) minutes batch run trial. The overall cost of producing the plant was One hundred and fifty thousand, three hundred and ten Naira only (N150, 310:00), which is affordable to many small and medium scale investors/entrepreneurs and local fabricators with small capital base considering the importance of the eucalyptus oil in Nigeria.
