Process Vessels

Dryer

Gravity Dryers, Purge and Conditioning Columns, and Spray Dryers

 

  • A client needed a compact dryer for removing moisture from wood chips fed into a downdraft gasifier.  A cross-flow moving bed dryer was designed that required no moving parts other than commercial conveyors feeding and unloading the dryer. The dryer was about 35% smaller than anticipated from eight proposed competitive dryers.
  • I've worked on spray dryers of every scale.  I have developed an innovative process for producing free-flowing, spray-dried powders.  I am excited to own an autographed copy of Keith Masters' Spray Drying Handbook.

Fluidization

Continuous Granulation

  • The key to wet pelletization is to ensure that the flow rates of liquid and solids are steady so that the optimal level of saturation is maintained. 
  • Using air assistance, I was able to provide a steady feed of fumed silica into a pin mixer without a scale to measure the loss in weight of the contents of the hopper. 

Cannabis

Removal of THC from Cannabis

  • I am a co-inventor of a continuous solvent-free process for removing THC from Cannabis. (Patent No. US 10765965)  I have never touched the product nor the starting material, but my chemical engineering and solids handling skills allowed me to design a moving bed bulk solids heat exchanger and moving bed bulk solids distillation column.  
  • If you have a batch process, I'll bet I can help you convert it into a continuous process.
