CAVITATION WASTEWATER TREATMENT FROM TOLUENE

The integral components of wastewaters from chemical and petrochemical enterprises are monocyclic aromatics (benzene, toluene, ethylbenzene, xylene, phenol and their derivatives). The toxic effect of these compounds turns out in violations of the activity of the human endocrine and central nervous system, the change in the species and trophic structure of biocenoses.

Reciprocal Solubility of Gasoline Fractions and Ethanol

Reciprocal solubility of gasoline and gasoline fractions in ethanol depending upon the aromatic hydrocarbon content in them has been investigated. Conditionally the ternary system “paraffin-naphthenic hydrocarbons–aromatic hydrocarbon–ethanol” demonstrates a bounded solubility with two pairs of the components. Ethanol solubility in hydrocarbons is only 1–3 %. The hydrocarbons solubility in ethanol depends upon water content in it and the temperature.
