background

Distillate HDS

PROCESS FEATURES
CONSER offers technology for the complete design (Basic Process Book) of Middle distillate HDS units.
The CONSER process is supported by a relevant experience and know how in HDS units design and by a deep knowledge of the performances of proven catalysts in different operating conditions.
CONSER experience covers also VGO HDS/Mild Hydrocracking operation.
In addition to the complete design of new units, HDS projects carried-out by CONSER typically include the following:

  • Debottlenecking and modernization studies
  • Improvement of performances to meet gasoil specifications (sulfur, cetane, aromatics)
  • Selection of optimum catalyst
  • Design for feedstocks ranging from 100% straight-run to 100% cracked gasoil
  • Influence of hydrogen purity

FLOW SHEET

DISTILLATE HDS C157 R


PROCESS DESCRIPTION
Fresh feedstock is mixed with hydrogen rich gas and heated to the reaction
temperature by heat recovery from reactor effluent and in a fired heater.
The reactor effluent is partially condensed. The gas phase is separated, purified by amine washing and recycled to the reaction section. The liquid phase is preheated and fed to a stripping column where unstabilized naphtha is separated from desulphurized/denitrogenated gasoil product.
