FEECO PIPE REACTORS
A pipe reactor is an acid-base reaction vessel used in the production of inorganic fertilizers. It is easily retro-fitted into existing granulation operations.
Phosphoric or sulfuric acid is fed into one side of the pipe, while gaseous or liquid ammonia is sparged into the reaction chamber, resulting in either ammoniated phosphate or sulfate hot melt material. The hot melt is discharged into the rotary granulator onto a bed of recycle material.
Though not applicable in all operations, the pipe reactor can offer significant savings in energy costs when employed, by capturing the heat released from the acid-base reaction to flash off moisture in the granulator.
FEECO is capable of meeting the requirements necessary for CE marking equipment.
All FEECO equipment and process systems can be outfitted with the latest in automation controls from Rockwell Automation. The unique combination of proprietary Rockwell Automation controls and software, combined with our extensive experience in process design and enhancements with hundreds of materials provides an unparalleled experience for customers seeking innovative process solutions and equipment.
