CO2 recovery process for supercritical extraction |
| abstract |
A carbon dioxide recovery apparatus (1) and process for supercritical extraction includes providing a process stream (61) from a supercritical extraction procedure (60) in which the process stream (61) includes pressurized carbon dioxide, extraction process waste and optionally at least one co-solvent; reducing the pressure of the process stream below critical pressure; venting low pressure carbon dioxide vapor (66) to exhaust; cooling the process stream to form a two phase mixture; separating the two phase mixture into a process liquid (71), containing co-solvent if present, and a process vapor phase stream (72); collecting the process liquid; filtering the process vapor phase stream (72) to remove particulates and optionally residual co-solvent; passing the filtered process vapor stream (81) through an adsorber (85) to remove trace impurities to form a purified carbon dioxide vapor stream (90); and, drying the purified carbon dioxide vapor stream (90) to remove residual water vapor. |
