GHU® ADVANTAGES

  • Higher liquid yields than coking processes
    • Output is 100 – 104% of liquid input volume versus approximately 80% of coking processes when hydrogen is supplied by other means than syntheses gas.
  • Gives refiners flexibility to process sour, acidic, heavier crude feed stocks or upgrade and recycle ATB / VTB residue back into the refinery overall process scheme producing high value product from a low value feed
  • Capability to adjust product slate to meet increasing demand for low sulphur petroleum products, including diesel and gasoline
  • Stability of upgraded crude produced in hydroconversion process is superior to coked products
  • Moderate operating conditions, temperatures and pressures allowing for simple reactor design with lower CAPEX and OPEX
    Lower operating and capital costs per barrel investment compared to conventional hydrotreating processes
