How is supercritical extraction used to extract high quality natural products?

supercritical carbon dioxide is pumped through extraction vessels containing the raw material.
The dense supercritical CO2 dissolves the required extracts and takes them into solution.
The solution passes through a pressure reduction valve.
The extracts then precipitate from the CO2 and collect in the separator
The CO2 is recompressed and recycled to the extractor.
