Ammonium Nitrate Fertilisers TRIZ Cases

Additives are fed through existing scrubber or evaporator steps to make particulate fertilizer with controlled content and lower equipment cost.

A polyacrylate-potassium acrylamide hydrogel enables compatible nitrogen fertilization with water retention, reducing leaching and fertilizer waste.

Lactobionic acid and its salts stimulate microbial biomass and soil aggregation, helping retain water and sustain soil nitrogen.

Recover nitrates, sulfates, and silicates from Jarosite waste while enriching the insoluble residue to at least 2000 ppm silver.

Stannous salts form protective layers on metal surfaces to prevent corrosion in low pH nitrogen-based fertilizer solutions.

An outer polycaprolactone layer overcomes high initial burst and lock-off effects in sulfur coated fertilizers by modulating water permeability.

Segmenting micronutrients into a core particle and plant fertilizers into a urea coating resolves soil deficiency trade-offs.

Recover urea dust from solidification gas streams to produce nitrogen-sulfur fertilizer without contaminating the urea synthesis plant.

Stabilizer materials reduce specific impulse and unconfined critical diameter in ammonium nitrate fertilizer compositions.

Applying 24-30% magnesium sulfate solution during granulation creates strong intergranular bonds, reducing caking and increasing strength.

Granulation produces homogeneous particles that maintain zinc solubility across pH levels while reducing dust and caking issues during application.

Adding a metal-chelating complex depresses the freezing point of ammonium thiosulfate, preventing crystallization during storage.

Closed-cell polyHIPE matrices prevent initial burst release of fertilizers by maintaining a substantially linear diffusion profile over extended periods.
