Description

The recovery still separates crude oil from solvents used in extraction processes. This procedure is achieved via the fractional distillation method, possible as a result of the difference in boiling point temperature of the two liquids. The apparatus consists mainly of an insulated boiler tank electrically heated from the bottom, and a water circulating condenser. Dirty solvent is manually poured into the tank whereas the condensed toluene vapor drips into a separate container. The treatment tank’s effortless removal facilitates the cleaning of slug deposits. Although the apparatus is explosion-proof, it should be installed in a hazard-free environment.
