Resumo

A novel process for the purification and recycling of CO2 (PRCO2) in a pilot scale unit was implemented and validated. The system is a 4-cycle pseudocontinuous process composed of on-line supercritical fluid extraction integrated with fractionation of extracts in three separation vessels, followed by purification of CO2 in adsorption column at subcritical conditions, and subsequent recycling of the purified CO2 with the aid of a storage tank. Turmeric and annatto were the plant matrices used for extraction and oat bran was used as adsorbent. The PRCO2 reduced the consumption of CO2 in 85.24% for annatto and 74.27% for turmeric, representing monetary savings of USD 186.40 and USD 111.83, respectively. Economical evaluation showed that the increasing of the number of cycles decreased the cost of manufacture from USD 349.60/kg to 122.67/kg for the processing of annatto and USD 91.31/kg to USD 36.56/kg for the processing of turmeric.
