DISTACT Distillation

Recently, major synthetic oil producers in Western Canada have switched from atmospheric bottoms to vacuum resids for processing bitumen. This raises the question of what impact this change might have on the coke induction period during thermal processing of these materials. To address this question, Athabasca bitumen (+343°C) was fractionated using Distact distillation into four distillates and resids.The selected boiling point cuts were 525°C, 575°C, 625°C, and 675°C. The coke induction periods of bitumen...
