Book Description
The effects of climate change have attracted concern globally which has led to an increase in research focused on diverse plans and technologies for mitigation. The use of solid catalyst in an amine based post-combustion CO2 capture (PCCC) has become a very attractive option as developments are actively ongoing to address some of the challenges that the conventional capture system faces. This research work evaluated the role that a new super acid, proprietary desorber catalyst (PDC) catalyst has on the amine degradation rate using a formulated optimum 4M DMAE/AMP equimolar blend in a full cycle bench scale CO2 capture pilot plant system. Three solvent blends, 4M DMAE/AMP, 2M PEI/AMP (0.3/1.7) and 2M PEI/HMDA (0.3/1.7) were screened in a preliminary study and compared with 4M BEA/AMP. 4M DMAE/AMP emerged as the optimum solvent amongst all the three formulated ones with high points of improvement in the desorption performance parameters. DMAE/AMP is a good replacement for BEA/AMP as it addresses the problem of potential nitrosamine and nitramine formation. Two basic catalysts, proprietary absorber catalyst (PAC), and activated carbon spheres (ACS) and one acid catalyst, PDC were also synthesized, characterized, screened, and compared with the existing basic catalyst, KMgO/CNT's and acid catalyst, Ce(SO4)2/ZrO2 respectively to evaluate their performances and how suitable they are for use in the PCC process compared to the existing ones. The introduction of ACS in the absorption system increased the rate at which the amine solvent absorbed CO2 by approximately 33 %. In the case of PAC, an absorption rate enhancement of approximately 29 % was obtained. PDC enhanced the CO2 desorption rate by approximately 25 % higher than the non-catalytic desorption using 4M DMAE/AMP. Degradation studies were finally conducted to examine the role that the solid acid catalyst, PDC plays in the stability of the selected amine blend system in a bench-scale pilot plant set-up. PDC inhibited the oxidative degradation rate of both DMAE and AMP by 25 % and 59 % respectively. This means 2M of DMAE would be depleted in 62 days in the presence of PDC compared to 46 days without PDC in an oxidative environment. Similarly, it would take 139 days for 2M of AMP to be depleted compared to 57 days without the presence of PDC. This translates into huge savings in operational cost if PDC is used as a catalyst to both enhance the desorption and limit degradation. The findings of this work would open up new discussions on how solid basic or acid catalysts can be beneficial in addressing one of the major drawbacks to the PCC technology, i.e. degradation.

Book Description
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

Gaseous Carbon Waste Streams Utilization

Gaseous Carbon Waste Streams Utilization PDF Author: National Academies of Sciences, Engineering, and Medicine
Publisher: National Academies Press
ISBN: 0309483360
Category : Science
Languages : en
Pages : 257

Book Description
In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.
