OIL DISTILLATION VACUUM COLUMN WITH THICKENED CLAD STEEL PLATE IN THE VAPOR HORN SECTION INSTEAD OF LINER MADE OF STAINLESS STEEL

摘要

PROBLEM TO BE SOLVED: To provide an oil distillation vacuum column with thickened clad steel plate in the vapor horn section instead of a liner made of stainless steel in order to protect erosion in the vapor horn section of the vacuum column. SOLUTION: A vacuum column for oil distillation incorporates a thickened clad steel 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 steel plates may provide better service than either conventional plug-welded liners or conventional shell plates with weld reinforcement. The thickened plate is a clad steel plate bonded to the inside face made of carbon steel with a solid stainless steel plate. The feed inlet is arranged to distribute feed across the thickened plates.
