This book was released on 1978 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Statistically designed experiments were carried out in a Union Process S-1 Batch Attritor involving a soft coal, Lower Freeport, and a hard coal, Montana Rosebud, in No. 6 and No. 2 fuel oil and water slurries. Energy requirements were determined from strain gauge measurements of the torque in the attritor impeller shaft and size distribution measurements in a Model TA Coulter Counter. It was found that the energy requirements for attrition milling depended strongly on the product size, the type of coal and the viscosity of oil. The data was fitted to a Charles type energy size reduction equation to allow the prediction of energy requirements for various operating conditions. Best estimates of the energy per ton of coal required to grind in No. 2 fuel oil slurries containing between 30 and 50% solids to a product with 10 .mu.m median size is 26 and 106 Kwh/t for Lower Freeport and Montana Rosebud, while a product with a 1 .mu.m mass median can be produced with energy input of 1500 and 6082 Kwh/t for the soft and hard coal, respectively. An appendix was abstracted separately.

Download or read book Advances in Clean Hydrocarbon Fuel Processing written by M. Rashid Khan and published by Elsevier. This book was released on 2011-09-23 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conventional coal, oil and gas resources used worldwide for power production and transportation are limited and unsustainable. Research and development into clean, alternative hydrocarbon fuels is therefore aimed at improving fuel security through exploring new feedstock conversion techniques, improving production efficiency and reducing environmental impacts.Advances in clean hydrocarbon fuel processing provides a comprehensive and systematic reference on the range of alternative conversion processes and technologies.Following introductory overviews of the feedstocks, environmental issues and life cycle assessment for alternative hydrocarbon fuel processing, sections go on to review solid, liquid and gaseous fuel conversion. Solid fuel coverage includes reviews of liquefaction, gasification, pyrolysis and biomass catalysis. Liquid fuel coverage includes reviews of sulfur removal, partial oxidation and hydroconversion. Gaseous fuel coverage includes reviews of Fischer-Tropsch synthesis, methanol and dimethyl ether production, water-gas shift technology and natural gas hydrate conversion. The final section examines environmental degradation issues in fuel processing plants as well as automation, advanced process control and process modelling techniques for plant optimisationWritten by an international team of expert contributors, Advances in clean hydrocarbon fuel processing provides a valuable reference for fuel processing engineers, industrial petrochemists and energy professionals, as well as for researchers and academics in this field. - A comprehensive reference on the range of alternative conversion processes and technologies - Provides an overview of the feedstocks, environmental issues and life cycle assessments for alternative hydrocarbon fuel processing, including a review of the key issues in solid, liquid and gaseous fuel conversion - Examines automation, advanced process control and process modelling techniques for plant optimisation

Available in PDF, EPUB and Kindle. Book excerpt: It is becoming evident that satisfying the ever-increasing global demand for energy is having a major impact on the environment. The technologies required to minimize such impacts are discussed here in an in-depth overview and review of a broad spectrum of energy and environmental issues. The first five sections of the book deal directly with scientific and technological topics: the production, transportation, and utilization of electric power; thermal science and engineering for energy conservation/utilization processes; gas hydrates; multiphase mechanics for energy and environmental technology; pollutants and radioactive wastes in the earth. The sixth section, unique in a book of this type, focuses on education, recording a panel discussion on solutions to problems of energy and environment. For specialists and nonspecialists alike, the book is thus a valuable guide to the technological challenges for the future.

Available in PDF, EPUB and Kindle. Book excerpt: More than 100 papers originating from 24 countries report the most recent advances in mineral processing and related fields. They represent a coherent combination of subjects from such diverse areas as communication classification, gravity, magnetic and electrostatic separation, flotation fundamentals and technology, hydrometallurgy, coal processing, industrial minerals, gold and silver, modeling, simulation and control, dewatering, agglomeration. Conventional and column flotation, reagent-surface interactions, handling of cyanide containing leach liquors in gold recovery processing of industrial minerals, especially boron minerals, and of coal receive special emphasis. The book is anticipated to be a reference material for those who practice mineral processing, coal preparation, hydrometallurgy, surface chemistry and environmental remediation. .
