Configurations

This machine is composed of two pumps, one for CO2 and another one for co-solvent, one extraction vessels, three separation vessels, and separated chiller and heater. It can reach max pressure (Pmax) of 350 bar and max temperature (Tmax) of 85 °C. There are two pressure set-points: the first one is for extraction vessels and the second one for separation vessels.

There are 5 pressure gauges and voltage can be chosen on request.

Carbon dioxide is continually recycled with a closed circuit for fluid recirculation. The system has PLC on board and is connected to the internet by an Ethernet network connection. It is fully automatic and is equipped with a touchscreen.

The system is PED/CE certified and ASME/UL certified.

Pumps

There are two pumps:

  1. The most important is the CO2 pump, the carbon dioxide is the principal solvent for the extraction of apolar chemical compounds.
  2. The secondary pump is used for the release of polar or medium apolar co-solvents during the process – useful for the extraction of chemical compounds with different degrees of polarity.

At the condition of max-pressure, these pumps can ensure a CO2 Flow of 25 kg/h.

The extraction process is based on small variations of solvent’s (CO2) pressure and temperature. These critical operations are ensured by several heat exchangers filled with water, which is heated or cooled by a separated, external chiller and heater.
