This book was released on 2018-09-03 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research was to optimize the electron donor supply in sulphate reducing bioreactors treating sulphate rich wastewater. Two types of electron donor were tested: lactate and slow release electron donors such as carbohydrate based polymers and lignocellulosic biowastes. Biological sulphate reduction was evaluated in different bioreactor configurations: the inverse fluidized bed, sequencing batch and batch reactors. The reactors were tested under steady-state, high-rate and transient-state feeding conditions of electron donor and acceptor, respectively. The results showed that the inverse fluidized bed reactor configuration is robust and resilient to transient and high-rate feeding conditions at a hydraulic retention time as low as 0.125 d. The biological sulphate reduction was limited by the COD:sulphate ratio ( 82% either using carbohydrate based polymers or lignocellulosic bio-wastes, in batch bioreactors. The biological sulphate reduction was limited by the hydrolysis-fermentation rate and by the complexity of the slow release electron donors.

Download or read book Fluidized Bed Technologies for Near Zero Emission Combustion and Gasification written by Fabrizio Scala and published by Elsevier. This book was released on 2013-09-30 with total page 1091 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fluidized bed (FB) combustion and gasification are advanced techniques for fuel flexible, high efficiency and low emission conversion. Fuels are combusted or gasified as a fluidized bed suspended by jets with sorbents that remove harmful emissions such as SOx. CO2 capture can also be incorporated. Fluidized bed technologies for near-zero emission combustion and gasification provides an overview of established FB technologies while also detailing recent developments in the field.Part one, an introductory section, reviews fluidization science and FB technologies and includes chapters on particle characterization and behaviour, properties of stationary and circulating fluidized beds, heat and mass transfer and attrition in FB combustion and gasification systems. Part two expands on this introduction to explore the fundamentals of FB combustion and gasification including the conversion of solid, liquid and gaseous fuels, pollutant emission and reactor design and scale up. Part three highlights recent advances in a variety of FB combustion and gasification technologies before part four moves on to focus on emerging CO2 capture technologies. Finally, part five explores other applications of FB technology including (FB) petroleum refining and chemical production.Fluidized bed technologies for near-zero emission combustion and gasification is a technical resource for power plant operators, industrial engineers working with fluidized bed combustion and gasification systems and researchers, scientists and academics in the field. - Examines the fundamentals of fluidized bed (FB) technologies, including the conversion of solid, liquid and gaseous fuels - Explores recent advances in a variety of technologies such as pressurized FB combustion, and the measurement, monitoring and control of FB combustion and gasification - Discusses emerging technologies and examines applications of FB in other processes
Download or read book Residence Time Distribution of Solids in a Multi compartment Fluidized Bed System written by Pajongwit Pongsivapai and published by . This book was released on 1994 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: In a conventional well-mixed fluidized bed the solids are almost completely mixed and the residence time for individual particles may vary between zero and infinity. For materials especially sensitive to the processing time, a wide distribution of residence time is extremely undesirable. A multi-compartment fluidized bed was proposed to minimize this problem. The two-compartment fluidized bed system was designed and experimentally investigated with positive results. Residence time distributions were measured with glass bead particles of 379 p.m mean diameter size. Tracer particles were colored glass beads which had exactly the same properties as the particles used for bed material. Two theoretical models were proposed to predict the flow behavior of solids through the two-compartment fluidized bed vessel. The results show the solids flow pattern can be described by the axial dispersion plug flow model and the tanks-in-series model. The parameters of both models can be determined by minimizing the sum of the squared differences between experimental data and model predictions curves. The influence of fluidization velocity, diameter of the orifice connecting the two adjacent compartments, and the height of the overflow exit orifice were investigated. The two-compartment fluidized bed can improve the residence time distribution of solids from a single fluidized bed. The residence time distribution of solids was also improved with decreasing fluidizing gas velocity. Orifice diameter and height of the overflow exit orifice did not influence significantly on particles flow in the two-compartment fluidized bed system. However, a solids mass flow through the partition orifice is predicted reasonably well, within moderate range of variance, by equation developed by de Jong (1965) [12].
