amine Thermal Reclamation technology development from lab to large scale pilot testing
Energy Procedia, 2013Co-Authors: Oddvar Gorset, Vibeke AnderssonAbstract:Abstract Aker Clean Carbon (ACC) is developing and testing improved CO2 capture processes, including a regeneration unit based on Thermal Reclamation techniques. Design and operation of amine Reclamation units was early identified by ACC as a challenge due to general limited experience with this type of equipment for this service. ACC has therefore teamed up with research institutes and suppliers with extensive knowledge of similar technologies and has since 2009 prepared for and performed technology development related to amine Reclamation using a stage-wise approach. This approach is outlined in the paper for one of ACC proprietary amine mixtures, CC6. Experience, know-how and concrete results from such a development course are fed back to ACC's in-house dimension tools for sizing and design of reclaimers for full-scale capture plants.

amine system problems arising from heat stable salts and solutions to improve system performance
Fuel Processing Technology, 2009Co-Authors: N K Verma, Anil VermaAbstract:Abstract This paper includes the significant on-site experience of the authors related to problems faced in amine systems and their possible solutions. Various reasons for the poor functioning of the amine system have been discussed. The amine system was designed as a closed circuit system with the primary objective of removing H 2 S, CO 2 , and other acidic components from liquid and gaseous hydrocarbon streams. A study of a model plant was considered wherein problems were solved systematically using the root cause analysis (RCA) approach. Heat stable salts were found to be one of the reasons for the mal-operation of the plant. The strategies were proposed for combating heat stable salts. For the plant under study, ion-exchange method was more suitable compared to off-site Thermal Reclamation. Overall annualized benefits by switching from offsite Thermal Reclamation to ion exchange based on-line Reclamation were of the order of 2 MM US $ and simple payback of less than a year.

a technology review for regeneration of sulfur rich amine systems
International Journal of Greenhouse Gas Control, 2018Co-Authors: Bharti Garg, Vincent T Verheyen, Pauline Pearson, Paul Feron, Ashleigh CousinsAbstract:Abstract Reducing the capital cost of post combustion CO2 capture by eliminating flue gas desulfurisation (FGD) pre-treatment, requires management of the amines preferential SO2 absorption. Novel technologies such as CS-Cap restrict the impact of SO2 to only a small fraction of the amine inventory resulting in high sulfate burden amines. Traditional Thermal Reclamation of these spent absorbents has advantages regarding simplicity, but ranks poorly for industrial ecology around PCC. These amines require low energy regeneration technologies compatible with their physico-chemical properties that also maximise the potential for valorising by-products. This review summarises the sulfur chemistry and outlines several amine Reclamation processes. It assesses the status of established and novel regeneration technologies for their applicability to high sulfur loaded amines. Should deep sulfur removal be required, a hybrid approach with initial bulk removal (as product) followed by a polishing step to further reduce sulfur is prospective. A preliminary estimation of the relative cost of using standard Reclamation methods for treating Sulfur loaded CS-Cap absorbent revealed the cost would increase due to its higher sulfate burden despite comparable treatment volumes. Research gaps are identified which would enable better comparison between the costs of traditional FGD versus higher Reclamation costs for combined capture technologies.

Achieving environmental sustainability in the shell mould foundry through Thermal Reclamation
NRC Research Press (a division of Canadian Science Publishing), 2019Co-Authors: Kuma P., Gandhi N. MohandasAbstract:Shell moulding is a process for producing simple or complex near-net-shape castings and maintaining tight tolerances with a high degree of dimensional stability. The main objective of the present research is to achieve environmental sustainability by Thermal Reclamation of the used shell mould foundry sand and present the results of achieving environmental sustainability. The investigations indicate that the Thermal Reclamation of the used foundry sand helps in achieving sustainability, and the selection of optimal process parameters like percentage of resin, catalyst, and fresh silica sand addition are very important in the shell mould foundry.The accepted manuscript in pdf format is listed with the files at the bottom of this page.
