This book was released on 1996 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous removal of SO2 and NOx using a regenerable solid sorbent will constitute an important improvement over the use of separate processes for the removal of these two pollutants from stack gases and possibly eliminate several shortcomings of the individual SO2 and NOx removal operations. Recent studies at PETC considered cerium oxide as an alternate sorbent to CuO. The present study aims to determine the effects of ammonia on the sulfation of the sorbent and to obtain a rate expression for the regeneration of alumina-supported CeO2 sorbents. In the past quarter the effect of ammonia on sulfation was investigated. It was found that the presence of ammonia affects the sulfation process unfavorably by forming ammonium sulfate species on the surface which subsequently decompose and cause sulfur loss from the surface. Since formation of surface ammonium sulfates increase the sorbent mass, it is difficult to deduce the magnitude of the sulfur loss from the surface only by thermogravimetric analysis.

Recent studies at PETC considered cerium oxide as an alternate sorbent to CuO. The present study aims to determine the effects of ammonia on the sulfation of the sorbent and to obtain a rate expression for the regeneration of alumina-supported CeO2 sorbents. The sulfation experiments indicated that 100 % conversion of ceria can be attained. Activation energy for the sulfation reaction was found to be 19 kJ/mol. The rate of sulfation reaction is first order with respect to SO2 and solid reactant concentrations. For regeneration with hydrogen, the activation energy and the reaction order with respect to hydrogen was found to be 114 kJ/mol and 0.56, respectively. The ceria sorbent preserved its activity and structural stability after 6 cycles. In the last quarter regeneration with methane was studied. Since regeneration with methane is more complicated than regeneration with hydrogen, the evaluation of data needs the development of new methods. The information obtained from these studies will be used to develop models for reactor-regenerator configurations. Subsequently, the SO2/NOx removal facility will be integrated into the power production process using a commercial process simulation software.

This book was released on 1994 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simultaneous removal of SO2 and NOx using a regenerable solid sorbent will constitute an important improvement over the use of separate processes for the removal of these two pollutants from stack gases and possibly eliminate several shortcomings of the individual SO2 and NOx removal operations. This process will allow simple and reliable cleanup of large volumes of stack gases at a competitive cost; produce a concentrated stream of SO2 which an easily be converted into valuable by-products; be compatible with existing power generation plants; and essentially eliminate the waste materials generated in some other sulfur removal processes. Department of Energys̀ Pittsburgh Energy Technology Center (PETC) and UOP/Shell have developed processes which both employ copper oxide-based sorbents in different reactor configurations, namely, former uses a regenerative fluidized bed while the latter employs a cyclic fixed bed contactor. More recent studies at PETC considered cerium oxide as an alternate sorbent to CuO{sup (1,2)}. Ceria improves the resistance of the alumina support to thermal sintering and produces a regeneration off-gas stream that can be easily converted to elemental sulfur. It has potentially higher sulfur capture capacity than copper. The objective of this research is to determine the effects of ammonia on the sulfation of the sorbent; to determine the effects of fly ash on the sulfation and regeneration of the sorbent; to obtain a rate expression for the regeneration of alumina-supported CeO2 sorbents; to model reactor configurations for a commercial scale combined CeO2/Al2O3 sorbent; and to study alternative designs, effects of design variables on the performance of the facility, and the economics of the process using the developed model.

Book excerpt: Enactment of the Clean Air Act Amendments and passage of state legislation leading to more stringent nitrogen oxides (NO(subscript x)) regulations have fueled research and development efforts on technologies for the combined control of sulfur dioxide (SO2) and NO(subscript x). The integrated removal of both SO2 and NO(subscript x), in a single system can offer significant advantages over the use of several separate processes, including such factors as reduced system complexity, better operability, and lower costs. This paper reviews the status of a number of integrated flue-gas-cleanup (FGC) systems that have reached a significant stage of development, focusing on post-combustion processes that have been tested or are ready for testing at the pilot scale or larger. A brief process description, a summary of the development status and performance achieved to date, pending commercialization issues, and process economics (when available) are given for each technology.

Available in PDF, EPUB and Kindle. Book excerpt: The book "Grapes and Wines: Advances in Production, Processing, Analysis, and Valorization" intends to provide to the reader a comprehensive overview of the current state-of-the-art and different perspectives regarding the most recent knowledge related to grape and wine production. Thus, this book is composed of three different general sections: (1) Viticulture and Environmental Conditions, (2) Wine Production and Characterization, and (3) Economic Analysis and Valorization of Wine Products. Inside these 3 general sections, 16 different chapters provide current research on different topics of recent advances on production, processing, analysis, and valorization of grapes and wines. All chapters are written by a group of international researchers, in order to provide up-to-date reviews, overviews, and summaries of current research on the different dimensions of grape and wine production. This book is not only intended for technicians actively engaged in the field but also for students attending technical schools and/or universities and other professionals that might be interested in reading and learning about some fascinating areas of grape and wine research.

Book excerpt: Simultaneous removal of SO2 and NOx using a regenerable solid sorbent will constitute an important improvement over the use of separate processes for the removal of these two pollutants from stack gases and possibly eliminate several shortcomings of the individual SO2 and NOx removal operations. Recent studies at PETC considered cerium oxide as an alternate sorbent to CuO. The present study aims to determine the effects of ammonia on the sulfation of the sorbent and to obtain a rate expression for the regeneration of alumina-supported CeO2 sorbents. In this quarter runs for methane regeneration were completed. The data obtained were evaluated and interpreted. When the sulfated sorbent was regenerated with methane coke formation on the sorbent was observed. Treatment of fresh sorbent with methane also resulted in coking. Coke formed on the sorbent disappeared very rapidly after the methane flow was replaced with nitrogen. The order of the regeneration reaction with respect to methane was estimated as 0:76 and the activation energy of the reaction was estimated as 130 kJ/mol. During repeated sulfation-regeneration cycles the decrease in the sulfur capacity after the first cycle was slightly more when regeneration was done with methane compared to that observed with hydrogen regeneration. In the subsequent 4 cycles, the ceria sorbent preserved its sulfur capacity. The regenerated sorbent was able to capture 1.5 sulfur atoms per cerium atom in less than an hour of sulfation, compared to S/Ce of 2.5 for fresh sorbents and 2 for sorbents regenerated with hydrogen.
