Modular Crude Oil Refineries

New Modular

Method

Chemex Modular has pioneered the new modular refinery manufacturing method. A modular refinery is a processing plant that has been constructed entirely on skid mounted structures. Each structure contains a portion of the entire process plant, and through interstitial piping the components link together to form an easily manageable process.

Refining Process Units

  • Hydro desulfurization Units (HDS) remove sulfur compounds from distillate products.
  • Catalytic Reformer Units (CRU) produce high-octane motor gasoline from naphtha.
  • Hydrocracker Units (HCU) increase diesel production from heavier products.
  • Desalters remove salt from crude oil prior to distillation to prevent fouling and corrosion.
  • Splitters / Stabilizers separate a feedstock into two products.

Modular Atmospheric Distillation

ADU

A crude oil plant or Atmospheric Distillation unit (ADU) is the first step in the refining process. The products derived from an ADU include naphtha, kerosene, diesel and ADU residuum. For larger capacity refineries, multiple ADUs can be combined to achieve higher throughput requirements.

Modular Vacuum Distillation

VDU

A Vacuum Distillation Unit (VDU) performs the same function as an Atmospheric Distillation Unit (ADU), but operates at a pressures less than atmospheric pressure.  It produces products from the ADU residuum.  For larger capacity refineries, multiple VDUs can be combined to achieve higher throughput requirements.
