Download or read book CO2 Capture by Reactive Absorption Stripping written by Claudio Madeddu and published by Springer. This book was released on 2018-12-15 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on modelling issues and their implications for the correct design of reactive absorption–desorption systems. In addition, it addresses the case of carbon dioxide (CO2) post-combustion capture in detail. The book proposes a new perspective on these systems, and provides technological solutions with comparisons to previous treatments of the subject. The model that is proposed is subsequently validated using experimental data. In addition, the book features graphs to guide readers with immediate visualizations of the benefits of the methodology proposed. It shows a systematic procedure for the steady-state model-based design of a CO2 post-combustion capture plant that employs reactive absorption-stripping, using monoethanolamine as the solvent. It also discusses the minimization of energy consumption, both through the modification of the plant flowsheet and the set-up of the operating parameters. The book offers a unique source of information for researchers and practitioners alike, as it also includes an economic analysis of the complete plant. Further, it will be of interest to all academics and students whose work involves reactive absorption-stripping design and the modelling of reactive absorption-stripping systems.

Download or read book Dynamic Modeling Optimization and Control of Monoethanolamine Scrubbing for CO2 Capture written by Sepideh Ziaii Fashami and published by . This book was released on 2012 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work seeks to develop optimal dynamic and control strategies to operate post combustion CO2 capture in response to various dynamic operational scenarios. For this purpose, a rigorous dynamic model of absorption/stripping process using monothanolamine was created and then combined with a simplified steady state model of power cycle steam turbines and a multi-stage variable speed compressor in Aspen Custom Modeler. The dynamic characteristics and interactions were investigated for the plant using 30% wt monoethanolamine (MEA) to remove 90% of CO2 in the flue gas coming from a 100 MW coal-fired power plant. Two load reduction scenarios were simulated: power plant load reduction and reboiler load reduction. An ACM® optimization tool was implemented to minimize total lost work at the final steady state condition by adjusting compressor speed and solvent circulation rate. Stripper pressure was allowed to vary. Compressor surge limit, run off condition in rich and lean pumps, and maximum allowable compressor speed were found as constraints influencing the operation at reduced loads. A variable speed compressor is advantageous during partial load operations because of its flexibility for handling compressor surge and allowing the stripper and reboiler to run at optimal conditions. Optimization at low load levels demonstrated that the most energy efficient strategy to control compressor surge is gas recycling which is commonly applied by an anti-surge control system installed on compressors. Trade offs were found between initial capital cost and optimal operation with minimal energy use for large load reduction. The examples are, designing the stripper in a way that can tolerate the pressure two times larger than normal operating pressure, over sizing the pumps and over designing the compressor speed. A plant-wide control procedure was used to design an effective multi-loop control system. Five control configurations were simulated and compared in response to large load variations and foaming in the stripper and the absorber. The most successful control structure was controlling solvent rate, reboiler temperature, and stripper pressure by liquid valve, steam valve, and compressor speed respectively. With the investigated disturbances and employing this control scheme, development of an advanced multivariable control system is not required. This scheme is able to bring the plant to the targeted set points in about 6 minutes for such a system designed initially with 11 min total liquid holdup time. Frequency analysis used for evaluation of lean and rich tanks on the dynamic performances has shown that increasing the holdup time is not always helpful to damp the oscillations and rejecting the disturbances. It means there exists an optimum initial residence time in the tanks. Based on the results, a 5-minute holdup can be a reasonable number to fulfill the targets.

Download or read book Simulation of CO2 Capture from Reformate Gas Using 30 Wt Monoethanolamine MEA written by Lakkana Piewkhaow and published by . This book was released on 2011 with total page 198 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen is usually produced by steam reforming of natural gas in large-scale processes. The growing demand for H2 production also means the increasing release of large amounts of CO2. Because of its greenhouse effect, it becomes very essential to remove CO2 from such plants. Also, the removal of CO2 is a very essential step in purifying the hydrogen produced. Carbon dioxide absorption using monoethanolamine (MEA) is considered as a promising technology to remove CO2. However, the major drawback of this system is the energy used during the solvent regeneration step. Therefore, reducing the energy consumption in the regeneration unit (re-boiler heat duty) of the capture process becomes very important in order to improve the process performance and make this process more economically feasible.

Download or read book Absorption Based Post Combustion Capture of Carbon Dioxide written by Paul Feron and published by Woodhead Publishing. This book was released on 2016-05-27 with total page 816 pages. Available in PDF, EPUB and Kindle. Book excerpt: Absorption-Based Post-Combustion Capture of Carbon Dioxide provides a comprehensive and authoritative review of the use of absorbents for post-combustion capture of carbon dioxide. As fossil fuel-based power generation technologies are likely to remain key in the future, at least in the short- and medium-term, carbon capture and storage will be a critical greenhouse gas reduction technique. Post-combustion capture involves the removal of carbon dioxide from flue gases after fuel combustion, meaning that carbon dioxide can then be compressed and cooled to form a safely transportable liquid that can be stored underground. - Provides researchers in academia and industry with an authoritative overview of the amine-based methods for carbon dioxide capture from flue gases and related processes - Editors and contributors are well known experts in the field - Presents the first book on this specific topic
Download or read book CO2 Capture written by Fabrice Lecomte and published by Editions TECHNIP. This book was released on 2010 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: CO2 capture and geological storage (CCS) is now recognised as being one of the pathways that can be implemented to reduce CO2 emissions and fight against global warming. But where, how and at what price can CO2 be captured? This book attempts to provide the answers to these questions, reviewing the state of the art of the technologies required. It presents the three main pathways considered in which the CO2 capture technologies are expected to be implemented, respectively: the post-combustion pathway, in which the CO2 contained in industrial flue gases is extracted; the oxy-combustion pathway, in which combustion is performed in oxygen to obtain flue gases with high CO2 concentration; and lastly the pre-combustion pathway, in which carbon is extracted from the initial fuel to generate hydrogen, whose combustion will produce only water vapour. The book introduces, for each pathway, the technologies currently available and those under development. It is intended for everyone wanting to gain a better understanding of the mechanisms implemented in CO2 capture operations, as well as the technological and economic challenges to be met to ensure that the costs generated by these operations are no longer an obstacle to their worldwide generalisation.Contents: 1.
