  • Data for the World

    Data for the World

    Research and the scientific method is about collaboration. This is why PSRI continually provides key data, experiments, and models to the research community.
  • Fines (dp

    Fines (dp<44 microns)

    PSRI understands how fines move through a fluidized bed and the gas it drags with it. Fines management can be critical in optimizing reactor productivity and standpipe pressure build.
  • Gas Distribution

    Gas Distribution

    It’s more than a good grid design. Bed hydrodynamics and particle properties have to be a consideration to mitigate gas bypassing.
  • Managing Backmixing

    Managing Backmixing

    For some chemistries, backmixing can be detrimental to product quality. PSRI knows how to manage and design around backmixing issues
  • Knowing Entrainment

    Knowing Entrainment

    PSRI understands how particles cluster and how that clustering can affect your cyclone performance.
  • Multiphase Injects

    Multiphase Injects

    PSRI knows how and where to inject gas, liquid and, solids into your fluidized bed.
  • Stripper Performance

    Stripper Performance

    PSRI has study the path to flooding in commercial sized strippers and how to mitigate such flooding.
  • Cyclone Reliability

    Cyclone Reliability

    Experimental and math modeling research at PSRI has shown how the vortex stabilizer in the cone region of a cyclone can significantly reduce cone erosion. Other merits were found as well.

/Consulting
PSRI has over 160 years of experience and over 225 reviewed publications in fluidization and particle technology.






/Solutions
PSRI works with hundreds of clients from all over the world in such industries as petrochemical, chemical, pharmaceutical, agricultural, power and energy, mining, food processing, and semiconductors. Chances are we have already seen your problem and know how to drive your success.

/Training
We don’t stop at solution space. We believe that training is an important part of maintaining success. Thus, PSRI offers intensive fluidization seminars all over the world, provides design manuals, procedures, methods, and webinars. PSRI believes that giving someone a fish is not as good as teaching someone how to fish.
/Research
PSRI has state of the art facilities to do research on an industrial scale. As a result, PSRI’s research is relevant to your problems and your bottom line. That is because wall effects matter, pressure effects matter, and temperature effects matter. With PSRI’s research, the data is relevant and applicable.

Particulate Solid Research Inc. (PSRI) is an international consortium of companies focused on the advancement of technology in the multiphase flows with granular and granular-fluid systems. Since 1971, PSRI has amassed a prolific amount of design data, technology, know-how, design criteria and models on all aspects of slurries, liquid injection, fluidization, entrainment, pneumatic conveying, attrition, erosion, distributor design, standpipes, solids transfer, and circulating fluidized beds.  From the data produced, PSRI has developed design correlations, models, procedures, methods and techniques which are among the best and most useful in the field.
