Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Distillation processes face inefficiencies when dealing with small amounts of starting raw material or compounds with close boiling points, as temperature inconsistencies within the distillation equipment lead to re-condensation of vapors, complicating the separation of fractions.
Innovation Solution
A distillation head with a vertically extending inner chamber and pinched region, equipped with Raschig rings and a double-layered airtight jacket, maintains a consistent temperature throughout the distillation process, preventing vapor re-condensation and allowing for efficient separation of compounds based on their boiling points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If temperature is raised to distill compounds with close boiling points, then distillation efficiency improves, but temperature inconsistency causes vapor re-condensation and separation precision deteriorates
Solution Approach 1:
The distillation head incorporates a pinched region that creates a localized temperature zone with different thermal characteristics. This localized structural modification allows specific regions to maintain optimal temperatures for preventing vapor re-condensation while overall heating continues to drive the distillation process efficiently.
Solution Approach 2:
The patent introduces vertical dimensionality to temperature control through the pinched region design. By creating a three-dimensional temperature gradient structure rather than uniform heating, the system maintains temperature consistency in critical vapor flow paths while allowing overall temperature elevation for efficient distillation.
2Speed
If heating is applied to distill small amounts of raw material, then distillation speed improves, but temperature inconsistency increases causing vapor re-condensation
Solution Approach 1:
The pinched region creates a localized thermal environment that maintains consistent temperature in the critical vapor generation zone. This localized structural feature ensures stable temperature conditions even when overall heating intensity is increased to accelerate distillation of small material volumes.
3Temperature
If uniform heating is applied throughout the distillation chamber, then temperature consistency improves, but energy efficiency deteriorates due to excessive heat distribution
Solution Approach 1:
Rather than uniform heating throughout the entire chamber, the pinched region design concentrates thermal energy in specific zones where it is most needed for maintaining vapor temperature consistency. This localized thermal management approach improves energy efficiency by avoiding unnecessary heat distribution to non-critical areas.
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 solution enables more accurate and efficient fractional distillation by maintaining a uniform temperature, reducing the need for repeated distillation and improving the purity of the distillate, as demonstrated by the use of infrared cameras showing no significant temperature gradient and effective separation of organic plant oleoresin, palm oil extract, and contaminated cooking oil.
Implementation Method 1
A distillation head is a unit used to conduct fractional distillation of a solid, removing impurities therefrom by boiling off parts based on their boiling temperature
Implementation Method 2
A plurality of Raschig rings are situated and supported by the pinched inner region of the vertically extending inner chamber
Implementation Method 3
Distillation or fractional distillation is carried out by heating a solid or liquid and removing gaseous vapors that are expelled therefrom
Implementation Method 4
This can be done while raising the temperature, as each compound boils at a different temperature
Implementation Method 5
a problem can arise when the temperature throughout the distillation equipment is not constant, and some of the vapor re-condenses before being evacuated from a distillation chamber

AI summary
An equal temperature fractional distillation chamber allows for more precise distillation by providing solid particulate matter with air spaces, such as Raschig rings, to radiate heat from the bottom of the chamber to an area where the vapors are separated. This area is unencumbered by Raschig rings or other devices and can be reduced in size, as necessary, to be less than 20% or 10% of the vertical height of the chamber. Further, a distillation key can enter from the top of the chamber and come down into the chamber with rings which encourage condensation of vapors which rise upwards. In this manner, a very controlled and accurate distillation can be achieved due to the higher heat capacity of the glass or other materials around the unencumbered region.
