The algal cells are harvested and dried; the oleoresin is extracted using either ,super critical CO 2, or a solvent (ethyl acetate). The Astaxanthin is diluted and standardized to 2,5 %, 5,0 %, 7,0 %, 10 %, 15 % or 20 % using olive ,oil,, safflower ,oil,, Sunflower ,oil, or MCT (Medium Chain Triglycerides).

As discussed below in Sections 2.3 and 2.8.1, CO 2 fluids eliminate the need of water while providing extra energy from the gas expansion to shorten the flowback time.In general, a fracturing fluid can be thought as the sum of three main components:Fracturing Fluid = Base Fluid + Additives + Proppant A fracturing fluid can be "energized" with the addition of compressed gas (usually either CO 2 or N 2 ).

Carbonaceous adsorbents were obtained from the ,residue after supercritical extraction of marigold, subjected to physical activation and used as nitrogen dioxide and iodine adsorbents. The effect of carbonisation and activation temperature on the textural parameters, acid–,base, character of the surface and sorption properties of the activated carbons was tested.

Refracturing can open new flow channels in ,oil, and gas reservoirs and communicate with the unused reservoir of the old fracture to increase ,oil, and gas production. The refracturing ,treatment, design for shale gas wells is largely based on the original wellbore completion and reservoir characteristics, rock mechanics, geostress characteristics, and fracture geometry [ 10 ].

The total mass flow rate (,CO 2, + EtOH) and solvent to sample ratio were set to 45 g min –1 and 84 g of ,CO 2, g –1 of oven-dried bark, respectively. To avoid loss of extract during depressurization, a stainless steel tube was connected to the outlet valve exiting from the separator and immersed in an Erlenmeyer flask filled with 100 mL of cold EtOH (ice bath).
