1. One promising source of renewable energy is algae-based biofuels. Microalgae variants have been developed that are up to 80% oil by dry weight. In one process to recover this oil, 7,500 kg/ day of dry algae biomass is extracted with supercritical carbon dioxide at 1970psig and 120C as shown in the diagram below. Oil is readily captured by the CO2 and leaves the extractor in a mixture of CO2 and oil that is 3.0% oil on a mass basis. A second stream containing the algae solids and remaining oils also leaves the extractor. The oil/ CO2 mixture is fed to a flash separator which reduces the pressure to recover 99% of the oils as a liquid. a) What is the daily output of liquid oil (in kg/ day) for this process? b) What volumetric flow rate of pure CO2( in m3/h ) at the extractor inlet is required
