A Small Size Essential Oil Refiner Using an Oscillating Heat Pipe for Essential Oil Condensation

Sakultala WANNAPAKHE

Abstract


This research investigated the design and building of a small size essential oil refiner using an oscillating heat pipe for essential oil condensation. Three condenser suit types were used: 1) condensation using water circulation, 2) condensation using a closed-end oscillating heat pipe (CEOHP) and 3) closed-loop oscillating heat pipe with check-valves (CLOHP/CV). CEOHP and CLOHP/CV were made from copper tubes with an inner diameter of 2 mm. R123 was used as the working fluid. The temperature of vapor for testing was 100, 110 and 120 °C. The vapor pressure for testing was 1, 1.5 and 2 bars.


Keywords
