PSRI Consulting

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

  • Developed technology specifications to   design gas distributors, catalyst injection system, expanded bulb, etc 
  • Conducted cold flow testing  at high pressures to identify the parameters that affect the electrostatics in the fluidized bed reactor leading to sheeting, developed instrumentation to measure the levels of static electricity
  • Designed cyclone system for gas-phase and condense-phase polyolefin reactors
  • Assisted in developing a reliable angled eductors to feed the collected fines back to the reactor
  • Designed dense-phase conveying system for product transfer and at the same time depressurize the polyethylene
  • Design and assess proper design polymer purge bins to insure limited volatile organic compound content and proper polymer residence time distribution during various modes of operation
  • Bin, hopper, feeder, and valve design and selection for storage and transportation of polymeric materials
  • Identified the source for producing angel hair during the conveying of resin
  • Developed catalyst process that provides optimum particle size distribution
  • Developed catalyst injection system that minimize catalyst attrition
