Technical Manual of BR120-50-01 Supercritical CO2 Fluid Extraction Equipment -2018 Ultimate Edition
BR120-50-01 Supercritical CO2 Fluid Extraction Equipment is a (25+25+25+25)L/40Mpa four-extraction, two-divided CO2 circulation system for material extraction (solid or liquid) at high pressure and temperature, in a separator. The conditions were changed so that dissolved substances were resolved for the purpose of separation. The device is mainly composed of: extraction kettle, separation kettle, CO2 high pressure pump, entrainer pump, refrigeration system, CO2 storage tank, heat exchange system, purification system, flow meter, temperature control system, and safety protection device. Auxiliary equipment and systems can meet the requirements and flowchart requirements of the Super Supercritical CO2 Fluid Extraction main system.
