Abstract: To make non-pressure nitrogenous fertilizer solutions, nitrogen oxides are prepared in a continuous process by burning ammonia in contact with a cobalt oxide catalyst started by an electric arc without preheating the gases. This burning forms nitrogen oxides which are reacted under negative pressure in a two-stage system. Nitric acid is formed in the first stage from a portion of the oxides by oxidizing them to nitrogen dioxide and reacting the nitrogen dioxide with water. In the second stage, the remaining nitrogen oxides are reacted at a pH between 8.0 and 8.4 in a gas-liquid contacting apparatus with an ammonium hydroxide reaction liquid, formed by mixing ammonia and water. The ammonium nitrite solution formed in the second stage is mixed with the nitric acid at a pH below 0.2, resulting in a solution of acidic ammonium nitrate to be flowed to the fields with irrigation water.

Abstract: NP- or NPK-containing fertilizers are manufactured from low-grade phosphate ore digested by nitric acid. Substantial problems have been experienced during previous attempts to produce fertilizers from phosphate ore having a high content of magnesium. The problems relate to the solution's viscosity, which becomes extremely high during neutralization with ammonia of the mother liquor, obtained by removal of most of the calcium as calcium nitrate-tetrahydrate from the digested phosphate. The novel process solves the viscosity problems by adjusting the conditions during ammoniation and the subsequent evaporation before prilling or granulation. The adjustment is characterized in that a substantial part of the remaining calcium is kept outside the process itself, at least during the neutralization and evaporation stages.
