Supercritical Fluid Extraction - an overview ...

Akgun et al. (2000) described the extraction and modeling of lavender flower essential oil with supercritical CO2 in a semi-continuous system at 8–14 MPa pressure, 35–50 C temperature and 1.092–2.184 g/min flow rate ranges of CO 2. They used a quasi-steady-state model as a function of extraction time, flow rate, pressure and temperature ...

Jan 20, 2017 CO2 extractions use temperature and pressure to effectively extract elements of the flower or trim. Facilities with advanced technology and machinery can experiment with supercritical carbon dioxide methods, which keeps CO2 at high pressures. In other words, extractors can finely control the rate at which cannabinoids and terpenes are extracted.

Extraction Equipment - Delta Separations

The supercritical phase has a unique combination of gas and liquid-like properties – it can effuse through solids like a gas (meaning it has low surface tension and can get deep into the nooks and crannies of the plant material to get access to the oils within), and dissolves materials like a liquid (important for extraction!). Supercritical ...
