Download or read book Computer Modeling and Optimization of OBOGS with Contaminants written by Joseph J. Beaman and published by . This book was released on 1988 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: The ultimate goal of this is to insure proper design of molecular sieve oxygen generation systems for the US Army's in-flight, medivac, and field hospital use. Specifically the research involves further development of an OBOGS model to include the effects of contaminants in the feed air. This OBOGS model can be used to optimize and design OBOGS systems with respect to system parameters such as cycle time and bed and valve dimensions. A three component feed OBOGS model has been developed. The model uses a linear oxygen isotherm and Langmuir type isotherms for nitrogen and the contaminant; the isotherms are uncoupled. The model assumes plug flow, isothermal conditions, and uses a common mass transfer coefficient (linear driving force) for all components. Radial gradients and intraparticle gradients are ignored. The model is expected to work best for contaminants that are relatively small and non-polar, so that mass transfer resistance is small.

Download or read book Use of Services for Family Planning and Infertility United States 1982 written by Gerry E. Hendershot and published by . This book was released on 1988 with total page 982 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 1982 statistics on the use of family planning and infertility services presented in this report are preliminary results from Cycle III of the National Survey of Family Growth (NSFG), conducted by the National Center for Health Statistics. Data were collected through personal interviews with a multistage area probability sample of 7969 women aged 15-44. A detailed series of questions was asked to obtain relatively complete estimates of the extent and type of family planning services received. Statistics on family planning services are limited to women who were able to conceive 3 years before the interview date. Overall, 79% of currently mrried nonsterile women reported using some type of family planning service during the previous 3 years. There were no statistically significant differences between white (79%), black (75%) or Hispanic (77%) wives, or between the 2 income groups. The 1982 survey questions were more comprehensive than those of earlier cycles of the survey. The annual rate of visits for family planning services in 1982 was 1077 visits /1000 women. Teenagers had the highest annual visit rate (1581/1000) of any age group for all sources of family planning services combined. Visit rates declined sharply with age from 1447 at ages 15-24 to 479 at ages 35-44. Similar declines with age also were found in the visit rates for white and black women separately. Nevertheless, the annual visit rate for black women (1334/1000) was significantly higher than that for white women (1033). The highest overall visit rate was for black women 15-19 years of age (1867/1000). Nearly 2/3 of all family planning visits were to private medical sources. Teenagers of all races had higher family planning service visit rates to clinics than to private medical sources, as did black women age 15-24. White women age 20 and older had higher visit rates to private medical services than to clinics. Never married women had higher visit rates to clinics than currently or formerly married women. Data were also collected in 1982 on use of medical services for infertility by women who had difficulty in conceiving or carrying a pregnancy to term. About 1 million ever married women had 1 or more infertility visits in the 12 months before the interview. During the 3 years before interview, about 1.9 million women had infertility visits. For all ever married women, as well as for white and black women separately, infertility services were more likely to be secured from private medical sources than from clinics. The survey design, reliability of the estimates and the terms used are explained in the technical notes.

This book was released on 1998-09-22 with total page 915 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers topics of equilibria and kinetics of adsorption in porous media. Fundamental equilibria and kinetics are dealt with for homogeneous as well as heterogeneous particles. Five chapters of the book deal with equilibria and eight chapters deal with kinetics. Single component as well as multicomponent systems are discussed. In kinetics analysis, we deal with the various mass transport processes and their interactions inside a porous particle. Conventional approaches as well as the new approach using Maxwell-Stefan equations are presented. Various methods to measure diffusivity, such as the Differential Adsorption Bed (DAB), the time lag, the diffusion cell, chromatography, and the batch adsorber methods are also covered by the book. It can be used by lecturers and engineers who wish to carry out research in adsorption. A number of programming codes written in MatLab language are included so that readers can use them directly to better understand the behavior of single and multicomponent adsorption systems.

Download or read book Pressure Swing Adsorption written by Douglas M. Ruthven and published by John Wiley & Sons. This book was released on 1996-12-17 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pressure Swing Adsorption is the first book that provides a coherent and concise summary of the underlying science and technology of pressure swing adsorption (PSA) processes at a level understandable to the practising engineer. PSA has achieved widespread commercial acceptance as the technology of choice for hydrogen purification, air separation and small scale air driers. However, PSA has numerous other actual and potential uses such as the recovery of methane from landfill gas, the production of carbon dioxide and other large scale applications. Since the design and optimization of a PSA process requires a somewhat mathematical model, two chapters of the book provide in-depth information on equilibrium theory and dynamic numerical simulation. However, this mathematical material will also help the general reader develop an understanding of the principles and strenghts and limitations of various approaches. PSA engineers, chemical engineers, environmental chemists, academicians and managers who must make informed decisions about purchasing costly PSA systems will find Pressure Swing Adsorption of particular value.
