Fuel Blending Apparatus for Ethanol-Adaptive Volatility Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fuel blending methods require refineries to produce and distribute multiple grades of gasoline, one with and one without ethanol, to meet regulatory volatility requirements, leading to logistical challenges and potential sales disruptions due to ethanol shortages.
Innovation Solution
A fuel blending apparatus that uses an electronic control unit to adjust fuel component proportions, ensuring a single gasoline blend meets regulatory requirements when sold with or without ethanol, by adjusting Reid Vapor Pressure, distillation temperature, and vapor-liquid ratio temperature specifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple grades of gasoline are produced and distributed to meet regulatory requirements for both ethanol-free and ethanol-containing versions, then regulatory compliance is achieved, but logistical complexity and distribution challenges increase
Solution Approach 1:
The patent creates a single base gasoline blend that can serve dual purposes: sold as-is to meet ethanol-free regulatory requirements, or mixed with ethanol to meet ethanol-blend regulatory requirements. This universal blend eliminates the need for maintaining separate inventory streams for different gasoline grades, simplifying the distribution system while ensuring regulatory compliance for both market segments.
Solution Approach 2:
The invention merges the previously separate ethanol-free gasoline and ethanol-blend gasoline into a single base product formulation. By formulating one gasoline blend with adjusted volatility characteristics, the patent combines the functionality of two distinct products into one, reducing distribution complexity and enabling flexible response to ethanol availability.
2Adaptability or versatility
If gasoline is formulated to be mixed with ethanol but does not meet regulatory requirements until mixed, then ethanol-blend market demands are met, but sales are prevented during ethanol shortages
Solution Approach 1:
The patent enables distribution terminals to dynamically adjust their product offering based on ethanol availability. The single base gasoline blend can be adaptively sold either as ethanol-free gasoline (when ethanol is unavailable) or as ethanol-blend gasoline (when ethanol is available), ensuring continuous sales operations and market responsiveness without being constrained by fixed formulation requirements.
Solution Approach 2:
The invention changes the volatility parameters (Reid vapor pressure, distillation temperatures) of the base gasoline blend to fall within a specific range that allows the same product to meet regulatory requirements both with and without ethanol addition. This parameter adjustment enables the gasoline to function in multiple regulatory categories, ensuring sales continuity regardless of ethanol supply conditions.
3Ease of manufacture
If ethanol is added to gasoline, then octane properties and volatility characteristics change, but the resulting mixture may no longer comply with regulatory requirements
Solution Approach 1:
The patent performs preliminary adjustment of the gasoline base blend's volatility characteristics before ethanol addition. By pre-adjusting the Reid vapor pressure and distillation temperatures of the base gasoline, the system ensures that after ethanol mixing, the final blend will meet regulatory requirements. This preliminary action prevents compliance issues from arising after ethanol addition, maintaining both octane enhancement and regulatory compliance.
Solution Approach 2:
The invention applies preliminary anti-action by formulating the base gasoline with volatility parameters that anticipate and counteract the volatility changes caused by ethanol addition. The base blend is specifically designed with adjusted Reid vapor pressure and distillation characteristics that will, after ethanol mixing, result in a compliant final product. This preemptive adjustment prevents regulatory non-compliance before it occurs.

AI summary
A method and apparatus involve: determining a specification for a fuel volatility characteristic so that a fuel complying with the specification meets an applicable regulatory requirement for volatility with or without the addition of ethanol; and utilizing a fuel blending mechanism to blend a plurality of different fuel components in a manner meeting the specification. A different aspect involves a computer-readable medium storing a computer program that, when executed: determines a specification for a fuel volatility characteristic so that a fuel complying with the specification meets an applicable regulatory requirement for volatility with or without the addition of ethanol; and causes a fuel blending mechanism to blend a plurality of different fuel components in a manner meeting the specification.
