Abstract
In this article a study of the energy performance of a distillation system of ylang-ylang essential oil on a wood fire was carried out. To do this an analysis using the first and the second low of thermodynamics was made for each component of the distillation system. The analysis showed that the energy efficiency depends on the fration of oil to be distilled and that the whole system is very deficient. The exergetic and energetic analysis shows that it is in the combustion chamber that has a large amount of destroyed exergy and a strong energetic loss. The velocity of the air entering at the combustion chamber greatly influences the efficiency of the chamber. Indeed it has been found that the destruction of the exergy increases with the velocity of the air incoming air.
Highlights
In Comoros, the environmental degradation is a worrying subject whose effects become more and more visible
The analysis was performed for each component of the distillation system ranging from the combustion chamber to the condenser
It follows from the obtained results that it is in the combustion chamber that great energy losses and significant irreversibilities occur
Summary
In Comoros, the environmental degradation is a worrying subject whose effects become more and more visible. Comoros is one of the world’s leading producers of ylang-ylang, distillation methods are still traditional These models are made of a combustion chamber whose fuel is wood, a cucurbit serving as a boiler and a condenser. The exergetic analysis is a powerful tool for the evaluation of the energy quality and an efficient optimization of energetic systems None of these works studies the particular case of Comorian boilers. We are going to make an energy and exergy analysis of a Comorian traditional ylang-ylang essential oil distillation system. We did an energy and exergy analysis on each component of the distillation system and run simulations to see the energetic and exergetic behavior of the system with respect to each fraction of essential oil; knowing that is distilled into four fractions: the extra superior fraction (ES), the extra fraction (E), the first fraction (I), the second fraction (II) and the third fraction (III). The energy efficiency and the exergy efficiency change according to the fraction of oil to be distilled
