What is a nitrogen stripper

Manure is the largest source of nitrogen on the farm. This occurs in the form of ammonium or organically bound nitrogen. In addition, manure consists of 90% water. Circular Values was the first in the Netherlands to see the circular value of this and developed the Farmcubes Quadro Nitrogen Refining so that only the excess components are disposed of in concentrated form. The nitrogen is recovered in a liquid inorganic fertilizer such as ammonium sulfate or ammonium nitrate.  This results in a high quality fertilizer substitute, which brings in money. Ammonium sulfate is an important fertilizer for the plant that contains both nitrogen and sulfur. With the production of liquid ammonium sulfate on own soil, manure disposal costs are actually yields and there is no need to purchase fertilizer. This provides economic benefits for land-based dairy farming.

Nitrogen stripper, nitrogen cracker or ammonia stripper?

Refining nitrogen from manure is also called nitrogen stripping, or nitrogen cracking, hence this plant is also called a nitrogen stripper or nitrogen cracker. Because ammonia is stripped from ammonium, the term ammonia stripper is also sometimes used. These designations are sometimes used interchangeably. Ultimately, the same thing is meant and the concept of producing ammonium sulfate from manure or digestate is the same. The Farmcubes Quadro is the first of its kind! The Farmcubes Quadro is now in service on several farms.

The Process

In the nitrogen stripper / ammonia stripper, ammonium nitrogen, present in the thin fraction, is converted into gaseous nitrogen (ammonia). Ammonia is normally formed in the barn where it can escape as an emission stream, but in this system it is formed in a controlled manner and actually prevents emission. The ammonia passes through columns and is washed to produce ammonium sulfate. Nitrogen refining can work by using heat and/or by using pH increasing agents.

The first nitrogen stripper in the Netherlands

Circular Values was the first in the Netherlands to see the circular value of manure and thus the potential of using this process commercially. The Quadro nitrogen stripper was developed under the Farmcubes brand name. Circular Values therefore has years of experience in developing, manufacturing, installing and maintaining nitrogen strippers at various livestock farms. This knowledge allows us to develop and manufacture Farmcubes Quadro nitrogen strippers that are suitable for almost all situations.
