The pilot scale liquid CO2-extraction plant

The pilot scale liquid CO2-extraction plant is designed for performing experiments of CO2-extraction from solid raw material using liquefied gas in order to receive representative samples of CO2-extracts needed for study their compositions and properties, for pilot batch production and its testing in relevant industry. 

The extractor’s volume is 10 L that allows exposing to extraction process from 2 to 6kg of raw material and producing from 60 to 400g of an extract depending on raw material type.  

The plant consists of a vessel for liquefied gas, a temperature-controlled extractor, vaporizer, condenser, a miscella collector and a refrigerator unit. The extractor equipped with a quick-detachable hatch, observation glasses, a cooling coil (refrigerator) and a heating coil.  

Proposed laboratory liquid CO2 extraction plant allows assessing influence of temperature level, kind and grade of raw material crushing, process duration, speed and quantity of dissolvent feed, etc., on efficiency of the extraction.

In the issue of appropriate handling of obtained experimental data, an opportunity to predetermine indexes of optimal operating practices for industrial processing solid raw materials is afforded.

 The pilot scale liquid CO2 extraction plant:

E1 – condenser, E2 - vaporizer, E3 – vessel for dissolvent; E4 – storage tank, E5 – miscella collector, E6 – extractor, E7 - heat exchanger.


The extractor contains an internal thermocouple meant for monitoring temperature of the extraction operation. There are two monitoring actions: heating by electrical power and cooling by refrigerator. The controlling system is installed in this module.


The system is tested for 1 hour at up to 100 bar pressure point. 


Two-day training in installation, operation and maintenance of the plant in Sydney.

DDF (Australia) Pty. Ltd. guarantees quality operation of the controlling system and the plant itself in the process of extraction for one-year period and shall change any defective part except the parts that have to be changed normally.
