Green Granulation

Solution provider since 2009

Green Granulation is a world leading provider of fertilizer related process technologies, offering urea granulation and other fertilizer-related technologies. It is also the owner and developer of the state-of-the-art Cold Recycle Fluid-Bed Urea Granulation Technology (CRG) process. The patented CRG process was first successfully applied in a plant in China in 2013.

The Cold Recycle Granulation process is modernizing the Urea Granulation world; offering energy saving, low investment costs and high product quality by using a ground shaking new layout and revolutionary production process.

Characteristics and advantages of the Cold Recycle Granulation process

Low energy consumption thanks to:

  • reduced product layer thickness resulting in less heating of the fluidization air fan and consequently reduced amount of needed air
  • hydraulic urea sprayers use reduced amount of atomization air at reduced pressure
  • low pressure drop scrubbers reduce the power consumption of the exhaust air fan(s)
  • reduced amount of recovered urea dust combined with lower water content of the urea solution, typically 55% due to low atomization air and higher granulator scrubber temperature

Low investment thanks to:

  • low building height, typically 27m total height
  • low requested building strength, highest load bearing floor is at the granulator bottom at 17m, vibrating screens are located below the granulator
  • reduced granulator and cooler strength because of low fluidization air fan pressure and low scrubber exhaust fan suction pressure
  • bucket elevator capacity is only 30% of standard, lifts only fines and crushed product
  • reduced air ducting, air enters the scrubbers from the top and leaves the scrubbers from the side

Improved product quality thanks to:

  • low product moisture due to the combination of the Green Granulation hydraulic sprayers / sprayer layout
  • low end product dustiness due to slow cooling and highly improved product polishing in the cooler
