Chemical Recovery

AGRO's chemical recovery process consists of the following:

Soda Recovery
Lime Recovery

Soda recovery comprises of evaporators and low temperature incinerator systems, that operate at a much lower temperature than conventional recovery systems.

Low temperature incinerator System

Advantages

Low cost, environmentally friendly technology that can handle low concentration, high silica black liquor from any AGRO based raw materials like bagasse, rice/wheat straw, sarkanda etc. or any combination there of
Scaling and viscosity problems do not affect the process
Safe process for small/medium pulp mills, does not form any smelt
Flexible, widely applicable technology for alkali/ neutral sulfite black liquor
Can be scaled down to 30-35 TPD pulp mills
Low gestation period – 8-10 months
ROI in 30-40 months

Evaporator

Lime Recovery -- The Multi–compartment FluoSolids® Reactor usually consists of a reaction bed and one or more heat exchange beds for heat recovery. In a typical 3 stage unit as illustrated here, hot gases from the main calcining compartment are used to dry and preheat calciner feed. Fuel is directly injected into the reaction compartment, where temperature and atmosphere are closely controlled. Finally, heat is recovered from hot product solids and used to preheat the fluidizing air. Auxiliary vessels, such as Fluid Bed Spray Coolers or Indirect Coolers may be used to further cool product solids for ease of handling.
