Solvent reclaiming by sulfate precipitation for CO2 capture
No full texttextSulfate accumulates in the post-combustion CO₂ capture system and must be removed to re-use amine efficiently. Removal of sulfate from the amine-based postcombustion CO₂ capture system through a solvent reclaiming process may reduce CO₂ capture costs. This work determines the solubility of K₂SO₄ and Na₂SO₄ in 2 to 8 m PZ loaded with CO₂ and develops a thermodynamic and process model for the reclaiming process. At 40°C the solubility of Na2SO₄ in 8 m PZ with a CO₂ loading of 0.3 is 0.3 m Na2SO₄ and that of K₂SO₄ is 0.1 m K₂SO₄. Sulfate solubility in PZ solutions is represented by the empirical models: K₂SO₄: ln(Ksp) = 10.53I[superscript 0.3] - 0.98[PZ][subscript T] -3440/T - 2.42 ; Na₂SO₄: ln(Ksp) = 2.137I[superscript0.3] - .6505[PZ][subscript T] -826/T + 265 where [PZ][subscript T] = 2*(molality of PZ). A K₂SO₄ and Na₂SO₄ solubility thermodynamic model was developed in the eNRTL framework in the Fawkes model for PZ/CO₂/H₂O in Aspen Plus[trademark]. The energy cost of the Na process when removing the equivalent of 100 ppm SO₂ from the flue gas, ranging from 0.1-0.8/ton CO₂). The K₂SO₄ recovered in the process can be used as fertilizer. However, the KOH will still cost 2/tonne CO₂. The chemical cost for the Na case is $0.7/tonne of CO₂.Chemical Engineerin
An Insight for Cursive Context-Specific Printed Script Recognition
No full textThe greatest challenge of machine learning problems is to select suitable techniques and resources such as tools and datasets. Despite the existence of millions of speakers around the globe and the rich literary history of more than a thousand years, it is expensive to find the computational linguistic work related to Punjabi Shahmukhi script, a member of the Perso-Arabic context-specific script low-resource language family. This paper presents a deep insight into the related work with summary statistics, advocating the popularity and success of artificial neural networks and related techniques. The paper includes support from recent trends from the authentic sources based on the top-level researchers' feedback including the machine learning frameworks. A comprehensive comparison of the most popular deep learning techniques convolutional neural network and the recursive neural network has been presented for the cursive context-specific scripts of Perso-Arabic nature. The overview of the available benchmark datasets for machine learning problems, especially for the Perso-Arabic group, is added. This paper incorporates essential knowledge contents for the researchers in machine learning and natural language processing disciplines on the selection of algorithms, architectures, and resources
Islam: Extremism and Moderation
No full textIslam has, for many years now, been torn between radical fundamentalist groups and the more intellectually moderate groups. With both groups claiming to follow the true Islam, an individual may have a difficult time in practicing one’s faith.
The ambition of this essay will be to investigate some of the major differences between the movements, more specifically the Wahhabi/Salafi movement practiced in Saudi Arabia and the more moderate approach emphasized by numerous Islamic Scholars. Grappling with these issues in my own search for the authentic Islam, this essay will provide a view of both sides with an attempt to justify the moderate position over the strict, literalist one. The intention is to show why the moderate intellectual position is more rooted in Islamic principles and values than the monotonous fanatic position. Due to the many sects, some with more extreme positions like the Khawarij alongside the more rational such as the Mu’tazilites, I decided it would be an enlightening task to break down both sides and challenge the history of both.Peer reviewedstudent peer-reviewed journal articlefinal article publishe
