Units P63 and P67

Unit Description

Units P63 and P67 each have two trickle bed reactors in series, online fractionation, gas recycle, liquid recycle, and an online process gas speciation.

The primary reactor of each unit can operate adiabatically and has four catalyst beds with inter-bed hydrogen quench. The secondary reactor of each unit can operate isothermally with one catalyst bed.

Additional attributes to note

  • Both P63 and P67 have the following configuration options:
  • Utilize either only the primary reactor or both the primary and secondary reactors in series.
  • Ability to withdraw inter-reactor samples.
  • Online fractionation via:
  • A pressurized tower.
  • Two atmospheric towers.
  • Utilize either once-through gas or recycle gas operations.
  • Liquid recycle.
  • Each unit is steam traced to allow for processing heavier, more viscous materials.

Project Examples:

  • Biomass Derived Fuel Product Upgrading

    While various routes are available for converting biomass into transportation fuels, one economically viable approach is to convert the biomass, such as woodchips, into a renewable crude stream via the Biomass Catalytic Cracking (BCC) technology developed by KiOR. KiOR is a next generation biofuels company which produces a renewable crude oil substitute called Re-CrudeTM, which is created through a BCC process that is based on the well-established fluid catalytic cracking process technology. The high-quality crude oil substitute can be upgraded into various transportation fuels such as gasoline, diesel and jet fuel using conventional refining equipment. These fuels are comparable to their fossil fuel counterparts, and can be used as drop-in fuels.

    KIOR has chosen Intertek Pilot Plant Services to conduct hydrotreating plant testing services to upgrade the Re-CrudeTM produced from KiOR’s Houston demonstration facility to transportation fuels.

  • Conversion of Coal into Transportation Fuels

    Intertek supported research conducted by the Penn State University Energy Institute in the development of high thermal stability jet fuel JP-900. Penn State had developed a new coal-derived jet fuel for supersonic military aircraft and turned to Intertek to conduct scale up and further process development. The jet fuel was made by deeply hydro-treating a blend of coal-derived liquid and light cycle oil, followed by deep hydrogenation.

    The coal-derived liquid was obtained from coal tar pitch produced by heating bituminous coal to high temperature in steel plant coke ovens and was provided by Koppers Chemical Company. The light cycle oil was provided by United Refining Company.

    In 2008, Intertek completed production of 4,000 gallons of fuel that meets the Air Force's JP-8 specifications with the high stability characteristics of JP-900. Intertek provided fix bed hydrotreating / hydrogenation services in support of this effort.
