Abstract

liquid-liquid extraction in a mixer tank was widely used to reach a certain mass transfer rate. Mass transfer rate in a mixer tank extractor is declared as mass transfer coefficient. This research intends to learn how mass transfer coefficient does in a mixer tank extractor and variables that influence mass transfer coefficient.  Determination of mass transfer coefficient in a mixer tank extractor is a function of mixer rate and characteristic of physical system.  This system study about water – acetic acid – methyl acetic between CMC as a phase concentration in a solvent.  The influences of  variable to mass transfer coefficient in a equation of non-dimention group is; Sh=7396.05 Re0.82 Sch -0.35.For whirlmixer, rate is between 1 to 4 circle/s and solvent viscosity is between 1 to 6.18 cP, and for whirlReynold, rate is between 2500 to 1000 and whirlSchmidt is between 689.655 to 4262.07.

Abstract

 Abstract - The aim of this study is to measure gas emission (CH4 and CO2) coming from natural gas leak localization in the soil. Natural gas is injected into soil in different depths and then analyzed by gas detector and micro gas chromatography to know the values CH4, C2H6, C3H8, C4H10, C5H12, O2, N2 and CO2 which is spread out into soil. When there are leaks in the soil, methane (CH4) will spread out underground. Methanotropic bacteria will use this natural gas as an energy source and transform it into carbon dioxide. The micro gas chromatography data was found that the pipes injected from 20 cm leak are 77.16% CH4 loss in 70cm depth, 73.15% in 50cm depth and 14.08% in 20cm depth. And the pipes injected from 30 cm leak are 20.27% in 30 cm depth and 65.13% in 60 cm depth. Then, the pipes injected from 50 cm leak are 23.40% in 30 cm depth and 47.40% in 60 cm depth. The leak source is in 80 cm depth.
