Hydroprocessing pilot plant

The Chemical Engineering Department of Southwest Research Institute (SwRI) operates a fuel processing center that includes a hydroprocessing pilot plant and two continuous vacuum-distillation columns. Other unit operations are available including:

  • Filtration
  • Wiped-film evaporation
  • Partial oxidation
  • Blending

To accommodate a wide variety of feedstocks, from heavy raw shale oil to vegetable oils, the hydroprocessing facility is designed to operate at conditions up to 3250 psig and 1000°F in the reaction section and can recirculate 250 SCFH of hydrogen.

The configuration of the pilot plant equipment can be modified to meet the project needs for:

  • Hydrogenation
  • Hydrocracking
  • Hydroisomerization
  • Other fixed-bed reactor processing

Feed rates of up to five gallons per hour allow economical processing of fuel R&D test quantities of up to 5,000 gallons.

Example work at the SwRI Alternative Fuel Center includes:

  • Conversion of raw shale oil to ultra-low-sulfur diesel (ULSD) and jet fuel
  • Conversion of chicken fat to jet fuel
  • Processing of beef tallow and soybean oil to “drop-in” diesel fuel
  • Production of high purity octadecane from canola and soybean oils
