NUEVO SISTEMA PARA OBTENER COMBUSTIBLE COMPLETAMENTE RENOVABLES

Nuevo sistema para obtener combustibles completamente renovables.
Ingenieros norteamericanos ha desarrollado un sistema para obtener combustibles y otros productos químicos completamente renovables a partir del calentamiento rápido del aceite vegetal o del azúcar, dando lugar a monóxido de carbono e hidrógeno. La clave de este nuevo procedimiento radica en su velocidad y simpleza, que permite sintetizar combustibles y productos químicos y obtener gasolina sintética de una forma mucho más rápida y económica. El sistema no necesita de fuente de calor externa para mantener una reacción continua, lo que facilita las aplicaciones en tecnologías bioenergéticas. Por Marta Morales

Ingenieros del departamento de ingeniería química y ciencia de los materiales de la Universidad de Minessota, liderados por el investigador Lanny D. Schmidt, han ideado un proceso que permite producir combustibles y productos químicos completamente renovables a partir del calentamiento rápido del aceite vegetal o del azúcar, dando lugar a monóxido de carbono e hidrógeno. Cuando calentamos azúcar o aceite vegetal, el azúcar se pone negra y el aceite suelta mucho humo y acaba poniéndose de color marrón oscuro. Estas reacciones se originan por la descomposición de ambos productos hasta formar carbón.

BIODIESEL A PARTIR DE ALGAS

Los biocombustibles son un tema que está generando considerable atención últimamente. En EEUU se están invirtiendo grandes sumas en el desarrollo de los mismos. El etanol a partir de granos o celulosa, y el biodiesel a partir de aceites vegetales son los más conocidos, pero hay muchos otros. Uno de estos es el biodiesel a partir de algas. El cultivo de algas se estudiá al principio en la NASA como una forma de generar productos químicos en el espacio usando fotosíntesis y reciclando el CO2. El Departamento de Energía de EEUU llevó a cabo un programa de investigacion desde 1978 que se dio por terminado en 1996. En la actualidad el aumento del precio del petróleo y los problemas ambientales hicieron resurgir el interés en el tema.
Algunas especies de algas contienen aproximadamente 50% de su peso en aceite, lo cual supera las plantas oleaginosas como la soja.

ESTIMACION RAPIDA DEL PRECIO DE UN TANQUE DE ALMACENAMIENTO

A menudo se necesita saber con rapidez y fiabilidad cuánto puede pesar y costar un tanque de almacenamiento, o todos los tanques de un parque completo de almacenamiento, a partir de una información preliminar, y para ello es bueno tener algún procedimiento que nos permita conocerlo. Incluso en estimaciones detalladas en las que se van a pedir ofertas a suministradores, es conveniente que el Departamento de Estimaciones tenga procedimientos rápidos que sirvan para poder trabajar sin necesidad de esperar a la llegada de las ofertas y para contrastar y comparar éstas cuando nos lleguen. Las fórmulas de cálculo expuestas a continuación sirven exclusivamente para “estimar”, y tienen la ventaja de que pueden emplearse con una información básica.

Handbook of Chemical and Environmental Engineering Calculations

Because of the ubiquitous nature of environmental problems, a variety of scientific disciplines are involved in the development of environmental solutions. The Handbook of Chemical and Environmental Engineering Calculations provides approximately 600 real-world, practical solutions to environmental problems that involve chemical engineering, enabling engineers and applied scientists to meet the professional challenges they face day-to-day. The scientific and mathematical crossover between chemical and environmental engineering is the key to solving a host of environmental problems. Many problems included in the Handbook are intended to demonstrate this crossover, as well as the integration of engineering with current regulations and environmental media such as air, soil, and water. Solutions to the problems are presented in a programmed instructional format. Each problem contains a title, problem statement, data, and solution, with the more difficult problems located near the end of each problem set. The Handbook offers material not only to individuals with limited technical background but also to those with extensive industrial experience.

Handbook of Petroleum Product Analysis

An increasing variety of petroleum feedstocks has produced an ever diversifying array of petroleum products. Consequently, new analytical techniques are constantly being developed in order to determine the appropriate applications for these new products. The Handbook of Petroleum Product Analysis provides detailed explanations of the necessary standard tests and procedures that are applicable to these products in order to determine the predictability of their behavior.
A companion to James G. Speight’s Handbook of Petroleum Analysis, this book describes the application of methods for determining the instability and incompatibility of petroleum products. More importantly, the Handbook provides details of the meaning of various test results and how they might be applied to predict product behavior. Written in a readable, conversational style that makes the book easy to use, Dr. Speight’s text does not compete with the Annual Book of ASTM (American Society for Testing and Materials) Standards; instead, the Handbook complements it by explaining the raison d’être of various testing methods, making a case for standardizing protocols across international boundaries. Chapters include:
-Naphtha
-Aviation Fuel
-Kerosene
-Distillate Fuel Oil
-Asphalt
Chemists and engineers in the refining industry, as well as students, will find Dr. Speight’s Handbook to be an accessible, invaluable guide to understanding the methods for analyzing petroleum products.

Plant Design and Economics for Chemical Engineers

The fifth edition of Plant Design and Economics for Chemical Engineers is a major revision of the popular fourth edition. There are new chapters on process synthesis, computer-aided design, and design of chemical reactors. A traditionally strong feature of the text, economic analysis, has been revamped and updated. Another strength, equipment sizing and cost estimation, is updated and expanded as well. These improvements also reflect changes in equipment availability.
The numerous real examples throughout the book include computer or hand solutions, and often both. There is a new increased emphasis on computer use in design, economic evaluation, and optimization. Concepts, strategies, and approaches to computer use are featured. These concepts are not tied to particular software programs and therefore apply to wide a range of applications software, of both current and future release.

The Biodiesel Handbook

Biodiesel is the form in which vegetable oils and animal fats are used as renewable diesel fuel. Whether it is created as neat diesel fuel or in blends with petroleum-based diesel fuels, biodiesel represents a positive alternative to fossil fuels. Many researchers around the world have dealt with the legislative, chemical, and engineering issues that result from the study of biodiesel. The Biodiesel Handbook summarizes these issues and how they have been dealt with, but also presents new data and technical information. Chapters include summaries on legislative and regulatory efforts around the world, the history of vegetable oil-based diesel fuels, the basic concept of the diesel engine, and glycerol, a valuable byproduct of biodiesel production. As the most up-to-date resource on biodiesel available, The Biodiesel Handbook is a necessary book for people interested in renewable fuels.

Statistical Design and Analysis of Experiments, with Applications to Engineering and Science

Mason, Gunst and Hess have done a great deal of consulting in industry which has provided them with an understanding of the design and analysis of linear and nonlinear models. In fact, I have had some direct experience with Bob Mason from Southwest Research Institute. When I was working at a medical device company owned by St. Jude Medical Inc., Southwest Research Institute had been contracted to analyze data from one of our animal experiments for defibrillation thresholds. As the new statistician in the company I needed to get acquainted with their work. The book illustrates many designs using real world problems. The first 5 chapters (88 pages) cover elementary statistical concepts and methods. The next 6 chapters (145 pages) cover designs. Most standard designs are covered including full factorials, balanced incomplete blocks, latin squares, fractional factorials and nested and crossover designs. There is also a chapter on response surface designs including rotatable designs, central composite designs and Box-Behnken designs. The rest of the book, some 368 pages, deals with statistical analysis of data from designed experiments. It makes a very good reference source.
