Effects of Variables on a Soaker-Stripper Reactor for Thermal Cracking of Deasphalted Oil
Vast resources of heavy oils like Canadian bitumen are available and processed through many different schemes to bring a synthetic crude oil to markets. One effective scheme in use employs Solvent Deasphalting (SDA), a versatile upgrading process that uses light alkanes to precipitate the asphaltic …

Development of Measurement Methods for Monitoring the Effects of Shed Fouling in a Fluid Coker Stripper
Fouling of the stripper sheds in fluid and flexi-cokers restricts solids recirculation, leading to flooding and a unit shutdown. This thesis develops non-intrusive methods to detect fouling growth and provide advanced warning before critical operating limits are reached. Experiments were performed …

CO2 Separation Using Regenerable Magnesium Solutions Dissolution, Kinectics and VLSE Studies
… 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 the aqueous and solid phases. Three critical phenomena influencing the CO2 absorption process, …
