Training case study: Excess fouling in a debutanizer column reboiler
May 06, 2024
Coker debutanizer column bottom reboilers (Figure 1) are vulnerable to what is broadly identified as polymerization fouling due to their high operating temperatures and the significant diolefin content in the cracked naphtha feed. Industry experience has led many operators to limit the inlet temperature of the reboiler heating medium, usually heavy...

Case study: Reducing shellside maldistribution in a condenser
October 16, 2018
Summary An engineering, procurement, and construction company asked HTRI to investigate methods—constrained by permissible pressure drop—to mitigate shellside flow maldistribution for an X-shell condenser, using cold seawater on the tube side to condense an off-gas on the shell side. Challenge Determine optimal geometric design modifications that minimize maldistribution and potential structural...
