OIL DISTILLATION VACUUM COLUMN WITH THICKENED PLATE IN THE VAPOR HORN SECTION

摘要

A vacuum column for oil distillation incorporates a thickened plate that has a layer of erosion-resistant material that is thicker than the corrosion- resistant thickness of an adjacent column section. Use of thickened, explosive- or roll-bonded clad plates may provide better service than either conventional plug-welded liners or conventional shell plates with weld overlays.
