Continuous Distillation Systems

Continuous Borosilicate Distillation Systems

Goel Glass designs, engineers, and supplies turnkey Continuous Distillation Systems fabricated from high-purity Borosilicate Glass 3.3 and virgin PTFE. Unlike batch distillation units that experience cyclic downtime, fluctuating thermal gradients, and variable composition cuts, continuous fractionating columns maintain steady-state thermodynamic equilibrium, delivering uniform high-purity product streams 24/7 with minimal energy expenditure.

The continuous column comprises an upper rectifying section and a lower stripping section separated by an optimized feed preheater and liquid distributor. Raw feed is continuously metered into the column at an optimal thermal stage. Vapors ascending through structured or random borosilicate packings encounter counter-current reflux liquid descending from the overhead condensation system, facilitating intimate vapor-liquid mass transfer. Bottom residues are continuously circulated through a glass thermosiphon or falling-film reboiler, with top distillate and bottom effluent withdrawn simultaneously at steady-state rates.

For multi-component separations requiring the isolation of three or more distinct chemical fractions, Goel Glass provides multi-column fractionation trains configured in series ($n-1$ columns for $n$ components), arranged according to relative volatility and separation difficulty (direct split or indirect split trains).
