FEATURES
CONSER offers technology
for the complete design (Basic Process Book) of Vacuum units.
In addition to the design of new units, typical Vacuum distillation
projects carried-out by CONSER include the following:
- Revamping and
modernization studies
- Optimization
of TBP Cut Point vs. Con Carbon Residue and metal content by proprietary
mathematical model
- Selection of
wet or dry operation based on Clients requirements
- Straight-run
or Visbroken tar feedstocks
- Deep cut-point
technology

PROCESS
DESCRIPTION
Straight
run residue or VSB tar feedstock is preheated by heat recovery from
product streams in an exchanger train before entering a furnace where
temperature is typically increased to 410-430°C.
Heater effluent enters the Vacuum column where LVGO and HVGO are recovered
as side steams while producing a Vacuum Residue.
Typical distillate yields range from 45 to 60% depending on feedstock
characteristics and operating conditions.
