Abstract
Patchouli distillation using process direct steam contact has been done by
patchouli community in Indonesia has not been enough to produce the maximum
rendement and quality. Rendement with conventional refining raw materials
normal conditions ranged from 2-2.5% to the value of Patchouly Alcohol (PA)
30% ~ 32%. The rendement is influenced also by the condition of the raw
material. The rendement can be improved through the engineering process. It is
assumed that the low rendement is caused by the quality of steam distillation that
is at the level of saturation or a mixture so that the energy required for the release
of oil bonds in the raw material is not reached maximum. This research purposes
to develop a process using superheated steam to improve the quality of steam
distillation in an effort to drive the rendement using biomasssa as fuel. This
research has produced a distillation unit with a capacity of 20kg of raw material /
batch consisting of boilers with steam drum and superheater facilities, raw
material boiler, condenser and oil separator. Distillation test results showed that
an increase in the level of the state of the steam out of a boiler into a saturated
state with the superheated steam. Steady state in the steam drum and
superheater value of each 1,5bar/112oC; bar/140oC and produce to 20kg of raw
material obtained under normal conditions rendement 3.1% with 5.5 hour time
