However, several limitations in the used of this method include high solvent consumption, low extraction yield, solvent contamination, higher cost of extraction, and longer extraction time.
The advantages of this system include low initial cost, greatly reduced solvent consumption, shorter extraction times, quantitative lipid recovery, use of multiple extraction solvents, and reduction in cost per sample.
The experimental results indicated that SFE technique reduced the solvent consumption and extraction time with no adverse effect on the extraction yield and fatty acid composition of the oil.
Here: US and Norwegian reserves would last 10 years at current levels of consumption and extraction; Canada only eight, Iran 53, Saudi Arabia 55, the United Arab Emirates 75, Kuwait 117 - and Iraq: 526 fucking years!
Similarly, we observed that the city does not have any large scale waste water recycle and reuse policy and management; therefore, waste water should be recycled to avoid energy consumption during extraction stage.
It instead seeks community leaders firmly opposed to measures that facilitate additional fossil-fuel consumption or extraction, such as the construction of natural gas pipelines and fracking wells.
