“…Gaseous VOC breakthrough tests for molecular sieve adsorption have frequently been utilized to evaluate the equilibrium adsorption capacity (Q e , g VOC/g MS) (Yoo, et al, 2005;Lin, et al, 2005;Manjare and Ghoshal, 2005). Breakthrough tests of MEK adsorption (C = 1448 (1471 ± 319) and 440 (483 ± 183) ppm) were performed herein to verify the feasibility of the simulated equilibrium capacity data in Table 3.…”

“…The Langmuir (Eq. (3)) isotherm models are used to fit the experimental equilibrium capacity data (Q e ) with various inlet concentrations (C) for adsorption of a single VOC at a constant temperature (Chou and Chiou, 1997;Yun, et al, 1998;Manjare and Ghoshal, 2006;Choudary, et al, 2002;Yoo, et al, 2005;O'Connor, 2006)). …”

Internal circulation cabinets, equipped with adsorbents for emitted volatile organic compounds (VOCs), are extensively used to store organic solvents in Taiwanese university and hospital laboratories.This work evaluates how ketone and isopropanol (IPA) respectively influence the methyl ethyl ketone (MEK) adsorption capacity of a hydrophobic molecular sieve (MS) with a high Si/Al ratio of 1000, and concentration (C, ppm) are closely fitted using a Langmuir isotherm. Lower VOC concentration ratios less than 0.17 for mixing acetone and IPA respectively with MEK rarely affect the MEK adsorption by HiSiv 1000. However, the effect of competitive adsorption, which evidently reduces the adsorption capacity of MEK, is related to the higher mixture concentration ratio (> 0.80) of IPA to MEK. The experimental results show that the hydrophobicity characteristics of MEK, acetone and IPA were responsible for variation in adsorption capacity of hydrophobic molecular sieve. Working parameters of adsorbent materials in the internal circulation cabinet have been also provided for preventing breakthrough of VOC adsorption by the molecular sieve.
