Process Equipment

Equipment in the phosphate industry must endure extremely severe conditions. Equipment that can meet these conditions is not often found off-the-shelf.

The equipment must be simple, durable, and easy to maintain, while delivering superior process performance.

JPipe reactor

Pipe reactor for MAP and DAP production.
The JSA pipe reactor system has the following features:

  • Simple design with flexible configuration
  • Main reactor pipe achieves high NH3 adsorption
  • Ammonia sparging pipe
  • Granulator feed pipe with discharge nozzles
  • Easily cleaned by intermittent steam addition
Spinden Reactor

SPINDEN™ Reactor

The SPINDEN™  has been used in several MCP/DCP Animal Feed plant to increase plant capacity by reducing the recycle ratio.

The reactor has unique features that result in:

  • Low build up
  • Variable product size
  • Low Recycle ratio - with a pug mill system, the recycle ratios for mini-granular MCP/DCP typically range from 5:1 to 12:1 compared to 3:1 to 4:1 for the SPINDEN.
  • Higher Reaction Efficiency - based on experience, about 5% higher conversion of CaCO3 and 0.5-1.0% higher P
  • Reduced maintenance and power consumption - with reduced buildup inside the Reactor, maintenance as well as power consumption are reduced.

Phosphoric Acid Plant Mixing Tee

Mixing Tee for phosphoric acid recycle and sulfuric acid in phosphoric acid plant reactor. Has very long life and can increase reactor P2O5 efficiency.

Waste-Heat Ammonia Vaporizer

The increased energy supplied by vapor ammonia evaporates more water from the system so the dryer duty can be reduced and/or the plant can be fed with a lower acid concentration.  The heat recovered at the vaporizer is approximately 0.25 MJ / tonne.  Taking this duty as steam or natural gas savings translates into approximately $1.50-1.80 per tonne, a significant incentive and results in a payback in the order of 6 months.

Another benefit of adding an ammonia vaporizer in this location is a reduction of emissions.  This is due to the scrubbing action of the relatively clean condensate that is recirculated through the plate exchanger to help keep it clean.

KIMRE Cross-Flow Scrubber

KIMRE Cross-Flow Scrubber

A 200,000 m3/h cross-flow scrubber at JR Simplot. Has high scrubbing efficiency, but at the same time resists plugging and is easy to clean.
