FAQ
What is supercritical CO2 extraction?
Supercritical CO2 extraction is a process that uses carbon dioxide in its supercritical state (above 31.1°C and 73.8 bar) to extract compounds from materials. In this state, CO2 has properties of both a gas and a liquid, making it an ideal solvent for various applications.
How does the process work?
The process involves pumping CO2 through a heating chamber to reach supercritical state, then passing it through the material to be extracted. The CO2 dissolves the desired compounds, which are then separated in a collection vessel as the pressure is reduced.
What are the main advantages of CO2 extraction?
Key advantages include:
– Non-toxic and environmentally friendly
– Adjustable selectivity
– No solvent residue
– Energy-efficient
– Versatile for various materials
What types of materials can be processed?
Common materials include:
– Botanicals and herbs
– Cannabis and hemp
– Essential oils
– Spices
– Food ingredients
– Pharmaceutical compounds
How much does a CO2 extraction system cost?
Prices vary based on capacity and features:
– Lab-scale: $10,000-$50,000
– Production-scale: $50,000-$200,000
– Industrial-scale: $200,000+
What maintenance is required?
Regular maintenance includes:
– CO2 cylinder checks
– Filter replacements
– Pressure vessel inspections
