Product description

NH3-water is produced using the VP-Hobe Manure Valorisation system. The input pig manure or digestate is first separated into a solid and a liquid fraction. Separation takes place in a flotation unit and in a belt press sieve. A reverse osmosis unit processes the liquid fraction into a retentate concentrated-N/K2O product and a permeate product to be processed in the clean water production. The concentrated-N/K2O product will be further de-watered in an evaporator. The liquid passes through a falling film evaporator with mechanical vapour recompression. Heating the liquid in the evaporator causes water to evaporate. A vacuum lowers the boiling point, less energy is needed than when evaporating at normal atmospheric pressure. The ammonia in the incoming liquid is removed from the product flow by stripping and concentration into NH3-water (14% N). The evaporator further produces  a Potassium concentrate (25% DM), ammonium sulphate by scrubbing the vapour coming out of the evaporator. And condensate.

The NH3-water is a liquid fertilizer with 14%N. It is a potential RENURE fertilizer. RENURE fertilizers are based on processed manure fractions replacing chemical fertilizers. Costs for farmers will be approximately €20-40 per ton ex works.

Application can be done using liquid manure injection systems. Low emission application techniques are compulsory to prevent ammonia volatilization.
