Supercritical CO2 vs Steam Distillation Process Efficiency

Process efficiency is a key factor in essential oil extraction, influencing **speed, cost-effectiveness, and resource utilization**. This article compares **supercritical CO2 extraction** and **steam distillation** in terms of **processing speed, material efficiency, and energy use**.

1. Extraction Speed

• Supercritical CO2 Extraction: Faster processing times with **higher compound selectivity**.
• Steam Distillation: Longer processing times, requiring **constant heat application**.

2. Resource and Material Efficiency

• CO2 Extraction: Extracts **higher yields per unit of raw material**, reducing waste.
• Steam Distillation: **Lower material efficiency**, requiring **more plant material** for the same yield.

3. Energy and Cost Analysis

• CO2 Extraction: Uses **less energy per batch** due to a closed-loop system.
• Steam Distillation: Requires **high water and heat energy**, increasing operational costs.

4. Case Study: CO2 Extraction in High-Efficiency Essential Oil Production

A company switched to CO2 extraction, reducing **processing time by 50%** while improving oil yield.

5. Conclusion

For **higher process efficiency**, **supercritical CO2 extraction** is the better method. Companies like **SHANGHAI NORTH BROOKS** provide **CO2 SUPERCRITICAL EXTRACTION MACHINE** solutions for **faster, cost-effective extractions**.
