Modelling and control of distillation column
dspace.nitrkl.ac.incontrol. Distillation is one of the most common unit operation used in most of the chemical and petroleum industries. Distillation is used to separate two or more components from a homogeneous fluid mixture. The quality and purity of distillation is of paramount importance, therefore proper control of the system is necessary.
Essential Oils from Steam Distillation
www.engineering.iastate.eduSteam Distillation . Background This all-glass, vertical steam distillation unit, consisting of a hot plate, boiling flask, biomass flask, still head, condenser and receiver, is used for “dry steam” distillation of plant material (see equipment diagram below). Steam is produced in the boiling by heating distilled water with the hot plate.
