Flash distillation. Used oils subjected to conventional vacuum distillation invariably leads to thermal degradation of the addi-tives and fouling of the plant. However, thin ﬁlm evaporation under very high vacuum allows the gas and lubricant oil components to be separated from a high-boiling asphaltic residue. The residue Get price

Coke Formation in Vacuum Distillation Columns: A

The wash bed in the distribution system of a vacuum distillation column is one of the primary barriers that prevent entrained residue liquids from reaching the heavy vacuum gas oil (HVGO) draw off. This falling liquid stream can be contaminated with metals and hydrogen-deficient molecules and may seriously affect downstream conversion units. Get price

Crude Oil Separation Processes

Vacuum Distillation. The main objective of a vacuum or secondary distillation unit is to recover additional distillates from atmospheric residue (long residue). The atmospheric residue is distilled to provide the heavy distillate streams used to produce lube oil or as feed to conversion units. Get price
