Oil Performance

Vietnam is the world's leading country in growing and producing pepper trees. In this study, we attempted the optimization of white pepper essential oil extraction. The obtained oil was then subject to determination of constituent composition via GC-MS method. The essential oil performance achieved 3.6% by hydro-distillation process with optimal conditions (25 grams of fresh pepper, size 18, 120 minutes extraction, 130°C). A total of 23 volatile constituents were identified from the white pepper essential oil, with the major components being 27.4% of Limonene, 3-Carene 22,928%, Sabinene 17,622%, β-pinene 10.068%, α-Pinene 5.426%.

The essential oil of Citrus microcarpa peels was applied in many fields, and the methods to improve the efficiency of citrus exploitation were increasingly concerned. In this study, citrus essential oil was extracted from calamondin by hydrodistillation. This study was carried out to investigate the factors affecting the distillation of essential oils. The highest performance of the distillation process was 2.45 % with optimal conditions (material-water ratio of 1:3 g/mL, time of 2 h, the temperature of 120 ºC). Moreover, calamondin (Citrus microcarpa) peels oil extract was analyzed by gas chromatography-mass spectrometry (GC-MS). The primary compound of calamondin essential oil include limonene 96.925 %, β-myrcene 1.424 %, 1R-α-pinene 0.561 %, cyclohexene 0.343 %, 1R-α-pinene 0.561 % and β-cubebene 0.598 %.

Key words：Atmospheric and vacuum; distillation; process; pollution Abstract：The atmospheric and vacuum distillation unit was analysed on the device's size, composition, technical route and process. The results show that the flue gas produced by atmospheric and vacuum furnace is the main emission source, and the main pollutants in the flue gas are SO2, NOX and soot. The wastewater pollution is mainly electric desalting salt water, and it was treated in saline wastewater treatment plant in the factory.
