Removal of spilled petroleum oil from water bodies using hydrophobic porous absorbent has garnered considerable attention due to the simplicity, large-scale adaptability and robustness process. However, use nonbiodegradable synthetic during cleanup raised a secondary concern such as generating plastic pollutants that can accumulate in marine other ecosystems. To encounter this potential hazard,...
This paper presents a thorough analysis of direct microwave heating as sintering process ceramic materials. It questions why susceptor-assisted is used in most experimental works, although coupling preferable for taking advantage the possible beneficial effects field on phenomena. issue was investigated by conducting both experiments and numerical simulations. The consisted alumina yttria doped...
The lithium bromide chillers supplied from solar collectors are used to provide proper environmental conditions into industrial and civil buildings. To maintain the appropriate values for the temperature into the chiller's boiler, a control unit is introduced to avoid crystallization of the absorbent. The liquid flow process of the absorbent within the pipes of the chiller is a non-linear proce...
In the present work, radiation of sound waves from a coaxial duct is considered. This has an inner wall which infinite and piecewise acoustically absorbent material, while outer semi-infinite rigid. The analytical solution problem found by means Wiener-Hopf technique. Applying Fourier transformation to boundary value problem, explicit expression for scattered field obtained. end, some numerical...
Equations for the calculation of VO2, VCO2, and evaporative water loss were derived for use of a paramagnetic gas analyzer with a flow-through respirometry system and an open or closed mask. The magnitude of errors involved in the determination of VO2 with no CO2 absorbent are small (+/-3%) but may be greater if no H2O absorbent is used, unless an appropriate correction is made for evaporative ...
ALL modern volatile anesthetics produce carbon monoxide in strongly exothermic reactions with anhydrous carbon dioxide absorbents. Although desflurane produces the most carbon monoxide, the reaction with sevoflurane produces the most heat. Using real anesthesia machines, sevoflurane, and desiccated Baralyme® (Allied Healthcare Products, Inc., St. Louis, MO), peak absorbent canister temperatures...
Polypropylene hollow fiber membrane (PPHFM) contactor, with aqueous solution absorbent such as sodium hydroxide (NaOH), monoethanolamine (MEA) and diethanolamine (DEA), was designed and used to separate and fix CO2 from CO2/N2 gas mixtures. The factors that influence the separation properties of CO2/N2 were investigated. It was found that the CO2 removal efficiency is the best by using MEA solu...
