CO2 Separation Using Regenerable Magnesium Solutions Dissolution, Kinectics and VLSE Studies
… where CO2 from flue gases can be absorbed by magnesium hydroxide (Mg(OH)2) slurry at 52 °C in a column followed by a regeneration step in a stripper. CO2 absorption in a Mg(OH)2 slurry solution involves physical absorption of CO2 gas into the aqueous phase and subsequent chemical reactions in …

Development of seawater electrolysis with low-cost membranes for sustainable cement production and pretreatment
… used to selectively separate calcium (Ca2+) and magnesium (Mg2+) ions from seawater, precipitating them as calcium hydroxide (Ca(OH)2) and magnesium hydroxide (Mg(OH)2), respectively. These hydroxides can then be calcined into calcium oxide (CaO) and magnesium oxide (MgO), which are key raw …

Examination of Silica Removal with Solids Recycle for Reverse Osmosis Pretreatment
… that removal is tied mostly to the presence of magnesium. Furthermore, studies have shown that removal is best when the chemical softening process is operated at a pH of 10 or above. Magnesium hydroxide precipitates in this higher pH range thereby removing silica via a co-precipitation or …

Design and Operation of Multistage Flash (MSF) Desalination: Advanced Control Strategies and Impact of Fouling. Design operation and control of multistage flash desalination processes: dynamic modelling of fouling, effect of non-condensable gases on venting system design and implementation of GMC and fuzzy control
… NCGs on the overall heat transfer coefficient (OHTC) are studied. The release rate of NCGs is studied using Henry’s law and the locations of venting points are optimised. The results reveal that high concentration of NCGs heavily affects the OHTC. Furthermore, advance control strategy namely: …
