Solution Overview

Problem

Existing methods for treating naturally sourced oils to produce renewable fuels are energy-intensive, generate waste, and struggle to efficiently remove phospholipids and nitrogen compounds, limiting the choice of usable feedstocks due to unpredictable and complex mixtures of oils and greases.

Innovation Solution

A method to determine the ratio of total heteroatom content in hydratable compounds at neutral pH to the total content of that heteroatom, particularly phosphorus or nitrogen, to characterize the quality of a lipid composition and select an appropriate heteroatom removal treatment, using techniques like NMR and mass spectrometry to identify and quantify these compounds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional chemical and physical pretreatment processes are used to remove heteroatoms from naturally sourced oils, then heteroatom removal is achieved, but energy consumption increases and waste is generated

Engineering Contradiction:
Improveheteroatom removal efficiencyVSAvoidenergy consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent applies preliminary action by determining the quality parameter (ratio of hydratable heteroatoms to total heteroatoms) before selecting the treatment process. This allows optimization of the treatment sequence based on the actual composition, avoiding unnecessary energy-intensive steps for feedstocks that don't require them.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the parameter used to select treatment processes from generic feedstock classification to a specific quality parameter (ratio of hydratable phosphorus/nitrogen to total phosphorus/nitrogen). This enables more precise matching of treatment intensity to actual feedstock characteristics, reducing energy consumption.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If complex mixtures of oils and greases are used as feedstocks, then feedstock availability increases, but treatment predictability decreases

Engineering Contradiction:
Improvefeedstock rangeVSAvoidtreatment predictability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent implements feedback by measuring the actual quality parameter of each feedstock batch and using this information to adjust the treatment process selection. This closed-loop approach maintains treatment predictability even with varying feedstock compositions by adapting the process to each specific batch's characteristics.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent creates a universal quality parameter (ratio of hydratable heteroatoms to total heteroatoms) that can be applied to all types of naturally sourced oils and grease mixtures. This single parameter provides a common basis for predicting treatment requirements across diverse feedstocks, enabling reliable process selection regardless of feedstock complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Reliability

If traditional heteroatom removal treatments are applied without quality assessment, then treatment is performed, but cost efficiency decreases

Engineering Contradiction:
Improveheteroatom removalVSAvoidprocess cost
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent introduces dynamics by making the treatment process selection flexible and adaptive rather than fixed. The quality parameter measurement enables dynamic adjustment of the treatment sequence to match actual feedstock requirements, optimizing cost efficiency for each batch while ensuring reliable heteroatom removal.

Inventive Principle:
Principle #15Dynamics
