Refinery vacuum distillation units (VDUs) use ejector systems to establish and maintain distillation-column pressure for capturing valuable crude fractions and reducing vacuum residuum. Reliable ...

This article introduces a CDU-VDU configuration tailored for grassroots refineries, decoupling stripping and rectification sections via a dedicated flash drum to enable steam-free rectification.

A study has shown that steamflooding distillation effects would improve crude recovery from thin reservoirs with less viscous crude. Steam distillation means that steam injection will cause some ...
