  7. Limiting reflux ratios: engineering-resource.com As reflux increases number of plates require decreases. As minimum reflux value reached the number of plates require become infinite. The minimum reflux and number of plates require find in the same manner as in distillation

  8. Example with reflux: engineering-resource.com For system such as aniline-heptane-methyl-cyclohexanethe ratio of MCH to heptane in the extract is modestly greater than raffinite, so, large number of stages are needed to achieve the desired purity. further the low solubility of both solutes in aniline would mean a very large flow rate of solvent. so we use reflux concept.

  11. engineering-resource.com Sulfolane (also tetramethylenesulfone,is a clear, colorless liquid commonly used in the chemical industry as an extractive solvent. Sulfolane was originally developed by the Shell Oil Company in the 1960s as a solvent. Sulfolane is a compound, and it is readily soluble in water. Sulfolane solvent is widely used as an industrial solvent, especially in the extraction of aromatic hydrocarbons from hydrocarbon mixtures and to purify natural gas.

  15. Supercritical Fluid Extraction: engineering-resource.com A supercritical fluid is any substance at a temperature and pressure above its critical point. It can diffuse through solids like a gas, and dissolve materials like a liquid. Supercritical fluids are suitable as a substitute for organic solvents in a range of industrial and laboratory processes. Examples: Carbon dioxide and water are the most commonly used supercritical fluids
