Engineered specifically for nail salons, the Salon 5000 is a source capture air-purifying unit designed to capture chemicals, odors and particles associated with manicures and pedicures, before they become airborne. The Salon 5000 is equipped with 18 pounds of carbon to provide nail salon patrons and employees alike with clean, safe indoor air. Air Flow and Your AllerAir Air Purifier: We've noticed over the years that clients are very particular when it comes to using their AllerAir unit. Some like to run it 24/7, others only at night, some like to run it on high for a few hours then leave it on low for the rest of the day. So is there a science to choosing your air flow rate? We took this question to our technical department and here's what we learned: Particles: Technically speaking, dust, pollen, hair and other airborne particles actually respond well to a higher setting. That's because the air is drawn-in at a faster rate which make the particles "smack" into the fibrous web of the HEPA filter with greater force. This increases the chance that they'll get stuck in the HEPA. Using the high setting for a few hours may be an excellent "quick fix" strategy if you've just finished brushing your pet or are cleaning out a dusty space, but our technical expert was quick to point out that over the long term it's just as effective to keep your unit on and running on low. This will provide a continuous flow of air that will help keep the air fresh. Chemicals and Odors: For chemical and odor concerns there is a definite consensus ??? low is the way to go. That's due to the specific nature of the activated carbon used in AllerAir air purifiers. Activated carbon contains millions of tiny pores and fissures that trap chemicals, gases and odors. The longer these pollutants are forced to "hang around" in the carbon bed, the better chance they have of being adsorbed. Minimize

An ideal text for graduate level courses in transport phenomena for chemical engineers, Analysis of Transport Phenomena provides a unified treatment of momentum, heat, and mass transfer, emphasizing the concepts and analytical techniques that apply to all of these transport processes. The first few chapters establish the tools needed for later analyses while also covering heat and mass transfer in stationary media. The similarities among the molecular or diffusive transport mechanisms--heat conduction, diffusion of chemical species, and viscous transfer of momentum--are highlighted. Conservation equations for scalar quantites are derived first in general form, and then used to obtain the governing equations for total mass, energy, and chemical species. The scaling and order-of-magnitude concepts which are crucial in modeling are also introduced. Certain key methods for solving the differential equations in transport problems, including similarity, perturbation, and finite Fourier transform techniques, are described using conduction and diffusion problems as examples. Following chapters are devoted to fluid mechanics, beginning with fundamental equations for momentum transfer and then discussing unidirectional flow, nearly unidirectional (lubrication) flow, creeping flow, and laminar boundary layer flow. Forced-convection heat and mass transfer in laminar flow, multicomponent energy and mass transfer, free convection, and turbulence are also covered. The appendix summarizes vector and tensor operations and relations involving various coordinate systems. Based on twenty years of teaching and extensive class testing, Analysis of Transport Phenomena offers students both extensive coverage of the topic and inclusion of modern examples from bioengineering, membrane science, and materials processing. It is mathematically self-contained and is also unique in its treatment of scaling and approximation techniques and its presentation of the finite Fourier transform method for solving partial differential equations.

In contrast to traditional combustion, gasification technologies offer the potential for converting coal and low or negative-value feedstocks, such as petroleum coke and various waste materials into usable energy sources or chemicals. With a growing number of companies operating and marketing systems based on gasification concepts worldwide, this book combines the latest information and real-world experience in developing gasification technologies. Gasification Technologies: A Primer for Engineers and Scientists discusses gasification techniques and the benefits of each technology, including gas clean-up technologies and those used in hybrid systems and fuel cells. It also accounts for the primary products that are recovered and explains how these products are purified and can be used as fuel or for applications in petrochemical processes. The book describes the conditions in which optimal value intermediate products can be recovered, focusing on key factors such as oxygen or air blown reactor, operating temperature, internal and external heating, and reactor design. The authors also establish how gasification can help meet renewable energy targets, address concerns about global warming, and contribute to a better carbon management or achieving Kyoto Protocol commitments. Gasification Technologies provide a multidimensional and well-rounded examination of current technology, research, applications, and development challenges for the commercialization of this increasingly popular technology.

Hydrogels are a fascinating class of polymers which show an immense ability of swelling under the influence of temperature, pH value or concentrations of different species in aqueous solutions. The volume change can amount up to several hundred percent. This unique behaviour is already used in such applications like disposable diapers, contact lenses or drug-delivery systems. The ability to perform mechanical work has been shifted the technical interest more and more towards sensors and actuators exploiting the thermo-chemo-mechano-electrical coupling within hydrogels. The accuracy requirements for such devices are much more demanding than for previous applications. Therefore, a deep knowledge of both the material and the functional properties of hydrogel sensors and actuators is needed. The monograph describes state of the art and recent developments for these materials in sensor and actuator technology. Minimize
