Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for producing nitrogenous phosphoryl compounds are costly and inefficient, requiring complex processing steps that are difficult to implement in an industrial setting, and result in high-cost, solid compositions that are not easily applicable to low-cost substrates like urea, while animal waste-based fertilizers contribute significantly to greenhouse gas emissions.
Innovation Solution
A low-cost process for manufacturing fluid nitrogenous phosphoryl compounds by eliminating costly steps, using in situ formation of urease and nitrification inhibitors in a fluid suspension, which can be applied directly to animal waste to stabilize nitrogen and reduce greenhouse gas emissions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If current state of art methods are used to produce nitrogenous phosphoryl compounds, then high purity solid compositions are obtained, but the process becomes costly and complex with multiple processing steps
Solution Approach 1:
The patent extracts and eliminates unnecessary processing steps from the conventional multi-step synthesis process. Specifically, it removes steps for removing volatile solvents, separating inorganic chloride by-products, and purifying solid compounds, thereby simplifying the overall process while maintaining product quality
Solution Approach 2:
The reaction system performs self-purification through in situ formation of fluid compositions. The nitrogenous phosphoryl compounds are formed directly in a fluid state with inhibitors present, eliminating the need for separate purification steps. The system serves its own purification function through the inherent properties of the reaction mixture
2Ease of manufacture
If current methods are used, then nitrogenous phosphoryl compounds are produced as solid flowable powder, but they require dissolution in non-aqueous organic liquid delivery systems for application
Solution Approach 1:
The patent changes the physical state parameter of the nitrogenous phosphoryl compounds from solid to fluid composition. By controlling the reaction conditions and using fluid formation methods, the products are obtained as ready-to-use fluid compositions that can be applied directly without requiring additional dissolution steps or special delivery systems
Solution Approach 2:
The fluid composition serves multiple functions simultaneously: it is the reaction medium, the product carrier, and the application-ready formulation. This multi-functionality eliminates the need for separate delivery systems, as the fluid composition itself can be applied directly to substrates
3Quantity of substance
If animal waste is used as fertilizer, then essential nutrients for plant growth are provided, but microbes convert urea to ammonium ions and produce N2O greenhouse gas
Solution Approach 1:
The patent converts the harmful microbial nitrification and denitrification processes into beneficial inhibited processes. By adding nitrification inhibitors and denitrification inhibitors, the harmful conversion of urea to ammonium ions and the production of N2O are suppressed, while the nutrient content remains available for plant growth
Solution Approach 2:
The inhibitors are added to the animal waste composition before the harmful microbial processes can occur. The nitrification inhibitors prevent the conversion of ammonium ions to nitrite and nitrate, while denitrification inhibitors prevent the conversion of nitrate to N2 and N2O, thereby preemptively blocking the harmful pathways
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The process enables the production of low-cost, ready-to-use fluid compositions that can be easily applied to substrates, effectively stabilizing nitrogen and reducing N2O emissions, making high-tech fertilizers accessible to farmers at a lower cost and improving crop yields.
Implementation Method 1
The instant invention discloses low-cost, fluid suspension compositions comprising a combination of urease, nitrification and denitrification inhibitors that decrease the loss of nitrogen from animal waste and lessen the biological formation of the greenhouse gas N2O
Implementation Method 2
said one or more inhibitor particles are formed in situ in the manufacturing process of the fluid suspension compositions eliminating many of the costly processing steps that exist in the current state of the art
