The secret lies not just in the source but in the sophistication of the purification process.
For us at the helm of sourcing cutting-edge process equipment. The high vacuum long path rectification column represents the pinnacle of this sophistication. It’s a game-changer for fish oil EPA/DHA separation, ensuring unmatched purity and efficiency.
Ready to dive deep into this technological marvel? Buckle up, as we embark on a fascinating journey through the realms of high vacuum long path rectification tower!
Let’s unravel this technological marvel together, shall we?
Why is Purity in Omega-3 Production Non-Negotiable?
Omega-3 fatty acids, particularly EPA and DHA, are celebrated for their health benefits.
But here’s the kicker: not all Omega-3s are created equal.
The thermal process technologies of distilling these precious oils determine their purity and, by extension, their effectiveness.
Imagine sipping a fine wine that’s been meticulously aged versus gulping down a hastily brewed concoction.
The difference is night and day, isn’t it?
What Makes High Vacuum Long Path Distillation Stand Out?
This process is nothing short of a marvel.
The so-called thermal sensitivity, that is, at a certain temperature, the substance will occur polymerization, decomposition, and other reactions and suffer damage, therefore, the purification and separation must be
carried out under a certain lower temperature and pressure.
By employing a high vacuum, the working system dramatically lowers the boiling points of our target compounds, reducing the risk of thermal degradation.
And with the long path the vapors travel, it is assured that only the purest of the pure make it to the finish line.
It’s like having an elite marathon where only the best athletes compete.
The project reference in China and application datas have shown that this method significantly facilitating the concentration of Omega-3 ester up to 75% or higher.
But how does it achieve such feats of engineering?
Facing the Industry Challenges Head-On
Indeed, it addresses key pain points like oxidation and isomerization. But, is that all there is to it?
The molecular weight of fish oil fatty acids and most other fine chemical raw materials are large, with complex structures, high boiling points, and numerous impurities that have small differences in boiling points from the desired products.
This complexity poses significant challenges in the separation and purification processes, often becoming a bottleneck that restricts product quality and leads to significant performance disparities among products.
Furthermore, the thermal sensitivity common to these substances adds an additional layer of complexity and rigor to an already challenging separation and purification process.
While liquid-liquid extraction, crystallization, adsorption, and membrane separation are frequently used in the biochemical product separation process, distillation is generally the first consideration in biochemical engineering when facing separation technologies, accounting for more than 90% of separation unit operations.
This is especially true in the separation and purification of Omega-3 products from fish oil, where vacuum distillation is often employed due to the presence of heat-sensitive substances.
How Does It Fare Against Traditional Distillation Methods?
Vacuum distillation, is conducted under pressures lower than atmospheric pressure.
The thermal fractionating tower process is operated within an absolute pressure range of 13.3 to 3,990 Pa and is known as high vacuum distillation.
If the vacuum level exceeds the operational range of high vacuum distillation, the average free path of evaporating molecules increases significantly.
Under such conditions, conventional distillation columns become unsuitable, necessitating the use of specialized equipment designed for short-path molecular distillation. This method is termed molecular distillation.
In the pharmaceutical, fragrance, polymer, and similar sectors, where substances have high boiling points and are heat-sensitive, standard reduced pressure distillation does not achieve efficient separation.
Short-path molecular distillation, while effective for Omega-3 ethyl ester concentration applications and capable to enrich to about 50%-65% ratio, cannot always meet the demands for increased higher concentration for industrial production.
Therefore, a high vacuum rectification tower is employed to achieve both the desired separation efficiency and the necessary scale of industrial production for these sensitive materials.
Comparing it to conventional approaches, the advantages become starkly evident. But, what exactly sets it apart?
What Should You Look for When Choosing the Best Solution?
In crafting high vacuum rectification towers for the continuous thermal distillation process, particularly for the separation processing of high-boiling-point, challenging-to-separate, and heat-sensitive fine chemical products and intermediates, it is imperative to prioritize design features and selection criteria that address these specific challenges.
Here’s a detailed breakdown tailored for your process production line and process targets:
Design Features:
- Adequate Theoretical Stages: The tower must offer a sufficient number of theoretical stages to cater to complex separation requirements, ensuring the high purity of end products.
- Low Pressure Drop: Minimizing the pressure drop across the tower is essential to reduce reboiler temperatures, safeguarding heat-sensitive compounds from degradation.
Selection Criteria for Packed Towers:
Given the limitations of tray towers, such as significant liquid hold-up, higher pressure drops, and extended residence times, which are not conducive for high vacuum continuous distillation, packed towers emerge as the optimal choice.
The simplicity and lower resistance of packed towers, coupled with advancements in structured packing materials, have significantly improved their scalability and separation efficiency, making them particularly advantageous for handling heat-sensitive materials.
Key Points of Improvement:
- Customized Packing and Height: Tailoring the type of structured packing and its height based on the distinct gas-liquid states and separation requirements of the distillation and stripping sections can enhance separation effects while maintaining low-pressure drops and minimal hold-up volumes.
- Optimized Tower and Internal Component Design: High internal gas flow rates and flow resistance necessitate the optimization of tower diameters and the design of liquid collectors with ample gas passages to reduce pressure drops and improve gas distribution uniformity. Moreover, designing liquid distributors according to the varying liquid flow rates in the distillation and stripping sections ensures adequate spray points and stable distribution. Employing non-uniform distribution methods in specific areas can also enhance the initial distribution of liquids, thus boosting the separation capacity of packed towers.
Heating Equipment Selection:
Selecting the appropriate reboiler heating equipment is critical and must be based on the thermal sensitivity of the substances being processed.
The complex phenomenon of reactions occurring in heat-sensitive materials is influenced by the medium’s characteristics, temperature, heating duration, and the types and amounts of residual or dissolved gases.
