Industrial Borosilicate Fractional Distillation Units
Goel Glass designs and builds skid-mounted Fractional Distillation Units engineered for high-efficiency multi-component chemical separations, solvent fractionation, and high-purity chemical purification. Each unit combines a Borosilicate 3.3 reboiler vessel seated in an electric heating bath with an overhead packed column section filled with high-surface-area borosilicate Raschig rings or structured packing to maximize theoretical plates.
Overhead process vapors enter an engineered reflux splitter assembly coupled with a primary coil condenser. Using a manual or magnetically actuated reflux divider with digital timer controls, the operator can adjust the reflux-to-distillate ratio from 100% total reflux to complete forward takeoff. Overhead distillate is passed through an auxiliary sub-cooler and directed into twin graduated receiver vessels with vacuum equalization lines, enabling continuous fractions sampling without breaking vacuum.
