IsoTherming® Hydroprocessing

IsoTherming® Hydroprocessing Technology

Economical and flexible, this breakthrough hydroprocessing technology uses a novel liquid-full reaction system.

IsoTherming® Hydroprocessing Technology provides a solution to the daunting challenges refiners face to reduce sulfur in finished products to ultra-low levels while minimizing capital investment and operating costs. IsoTherming® Technology is proven to achieve stringent product specifications, improve margins, and ensure a safe and sustainable operating environment.

IsoTherming® Technology is suitable in grassroots or revamp applications for the following services:

  • Kerosene Hydrotreating
  • Transmix Hydrotreating
  • Diesel Hydrotreating
  • FCC Feed Hydrotreating
  • Mild Hydrocracking
  • Dewaxing
  • Gas-To-Liquid (GTL) Upgrading
  • Heavy Oil Upgrading

This innovative technology provides the hydrogen necessary for reactions through a saturated liquid recycle stream. By eliminating the need for a recycle gas compressor and ancillary equipment, operating costs are reduced. The hydrotreated liquid recycle stream also acts as a heat sink, resulting in few hot spots, reduced light-ends make, and decreased catalyst deactivation.
