Phytase Treatment for Ethanol Processing Scale Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Ethanol processing equipment experiences tenacious scale deposits due to phytic acid precipitating with soluble metals, leading to impaired heat transfer and production interruptions, as existing methods fail to effectively address the insoluble organometallic salt formation.
Innovation Solution
The method involves adding a phytase enzyme to ethanol-processing fluids to convert phytic acid salts into soluble inorganic phosphates, thereby reducing deposition and facilitating the removal of insoluble materials from processing equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If phytic acid is present in ethanol-processing fluids, then metal solubility is maintained, but insoluble organometallic salt deposits form on processing equipment
Solution Approach 1:
The patent changes the chemical form of phosphate compounds from organic phytates to inorganic phosphates through enzymatic hydrolysis using phytase. This parameter change in chemical composition prevents the formation of insoluble organometallic salts while maintaining metal solubility, thereby eliminating deposit formation on processing equipment and improving operational reliability
Solution Approach 2:
The patent introduces phytase enzyme as an intermediary substance that catalyzes the conversion of phytic acid to inorganic phosphates. This intermediary enzyme mediates the chemical transformation that prevents harmful deposit formation without directly interacting with the metal ions, thereby resolving the contradiction between maintaining metal solubility and preventing insoluble deposit formation
2Productivity
If scale deposits form on processing equipment, then heat transfer is impeded, but production interruptions occur
Solution Approach 1:
The patent applies preliminary anti-action by adding phytase enzyme to ethanol-processing fluids before scale deposits can form on processing equipment. The enzyme preemptively converts phytic acid to inorganic phosphates, preventing the formation of insoluble organometallic salts that would otherwise impede heat transfer and cause production interruptions, thereby maintaining production continuity
3Quantity of substance
If phytic acid precipitates with soluble metals, then metal solubility is reduced, but deposit removal is required
Solution Approach 1:
The patent applies inversion by reversing the conventional approach: instead of trying to remove deposits after they form, it inverts the strategy by preventing deposit formation in the first place through enzymatic conversion of phytic acid to inorganic phosphates. This maintains metal solubility and eliminates the need for difficult deposit removal operations
