Extractive industries use non-renewable resources in an unsustainable and environmentally harmful way. Mining, crude oil, and natural gas are examples. Forestry is not extractive. Environmental damage and depletion of resources are concerns, as well as the need for sustainable alternatives. An extractive industry is one that consumes or uses natural raw materials in an unsustainable […]
Fractional distillation separates volatile compounds based on boiling points, but some blends require extractive distillation. Azeotropes cannot be separated by fractional distillation. Extractive distillation uses a high-boiling solvent to change relative volatilities and separate compounds. The solvent must have a higher boiling point than the less volatile substance and be introduced as a vapor. Examples […]
