Volatile organic compounds absorption in a structured packing fed with waste oils: Experimental and modeling assessments
نویسندگان
چکیده
Volatile Organic Compounds (VOCs) having different polarities were absorbed in two viscous waste oils (a transformer oil and a lubricant, whose viscosities are equal to 19 mPa s 79 s, respectively) structured packing (1 m height) operated at counter-current. A synthetic hydrophobic solvent (PDMS 20, silicone oil) water also used as reference solvents. Removal efficiencies of VOCs up 80–90% measured. Nonetheless, owing higher viscosity, the removal lubricant significantly lower. deconvolution procedure, based on Higbie penetration theory, was developed deduce local mass transfer coefficients (kL kG) from KLa° values. These compared predictions models Billet-Schultes (BS) Song-Seibert-Rochelle (SSR), allowing conclude that SSR model better addresses influence viscosity than BS model.

Modeling of packed absorption tower for volatile organic compounds emission control
Development of chemical industry and high vapor pressure of volatile organic compounds (VOCs) have been caused that these materials recently be considered as a source of air pollution. These are different methods for separation of VOC from air that absorption by suitable and selective solvent is an efficient method. In this research, mathematical modeling of a packed absorption tower for separa...
متن کاملSource apportionment modeling of volatile organic compounds in streams.
It often is of interest to understand the relative importance of the different sources contributing to the concentration c(w) of a contaminant in a stream; the portions related to sources 1, 2, 3, etc. are denoted c(w,1), c(w2), c(w3), etc. Like c(w), the fractions alpha1 = c(w,1)/c(w), alpha2 = c(w,2)/c(w), alpha3 = c(w,3)/c(w), etc. depend on location and time. Volatile organic compounds (VOC...
متن کاملVolatile Organic Compounds in Uremia
BACKGROUND Although "uremic fetor" has long been felt to be diagnostic of renal failure, the compounds exhaled in uremia remain largely unknown so far. The present work investigates whether breath analysis by ion mobility spectrometry can be used for the identification of volatile organic compounds retained in uremia. METHODS Breath analysis was performed in 28 adults with an eGFR ≥ 60 ml/min...

This thesis describes efforts made on the development of an existing catalytic incinerator. The development work, called process characterization, consists of four general parts. These are the development of measurement methodology, the studying of construction materials, the selection of suitable catalysts and the testing of the effects of process operation conditions. The two application area...
