Oil refining laboratories

Oil refining laboratories

The oil refining laboratories at SINTEF consists of pilot units for catalytic upgrading of oil fractions close to industrial conditions. There has been a continuous project activity in the laboratories since 1981 in close collaboration with the industry and academia.

Services provided:

SINTEF offers contract research for the industry related to processes for catalytic reforming and isomerization of naphtha ("Octane Processes laboratory"), and for hydroprocessing of oil fractions ("Hydroprocessing laboratory"). The objective is to identify best catalyst technology and refinery conditions.

Octane Processes laboratory

In the Octane Processes laboratory, oil fractions are processed in a pilot unit to enhance octane number and meet fuel specifications of gasoline.

Three isothermal fixed bed reactors placed in salt bath for good temperature control. Separate temperature and pressure control. Separate supply of naphtha and hydrogen.

Equipment

Fixed bed reactors

  • 300 ml total volume, 50 ml catalyst
  • 1" tube (di = 19,3 mm), Length 1,25 m
  • Temperature: 160-530 °C
  • Pressure: 0-30 bar

Flow rates

  • Naphtha: 0-220 ml/h
  • Hydrogen: 0-2000 ml/min

Analysis equipment

  • Product distribution is measured by online GC analysis
  • Water analysis by Karl-Fischer titration (METHROM 831 KF Coulometer)
  • Chlorine analysis by titration

Hydroprocessing laboratory

In the Hydroprocessing laboratory, oil fractions including bio oil are processed with hydrogen in a pilot unit to meet specifications of transportation fuels.

Five isothermal fixed bed reactor units of different size. Separate temperature and pressure control. Separate supply of oil feed and hydrogen. The units are designed for continuous operation.

Equipment for destruction of produced H2S and NH3 by photo-oxidation and carbon-filtering.
