Borosilicate glass distillation column

Process Solutions for thermal separation Columns and internals for aggressive media Optimal solutions using separation columns for highly corrosive processes Thermal separation processes are often used in treating and cleaning chemicals. Very common are processes that involve two liquids or a liquid and a gas. The processes used mainly involve extraction, absorption, desorption or stripping, distillation or rectification. The process core in the columns consists of packings that provide the mass transfer surfaces; these involve specialised trays such as bubble-cap or sieve trays as well as random or structured packing. Especially for random and structured packing and in addition to support trays further internal components are required to wett all surfaces equally for optimum mass transfer. These additional components include liquid distributors that evenly distribute the incoming fluid over the column cross-section, and wall wipers to deflect liquid from the wall inside the column back into the packing. Further internal components are needed to control the liquid flow out of the column; demisters reliably restrain droplet drift at the upper end of the column, while collectors underneath the packing catch the reflux liquid, either removing the liquid from the column or feeding it back to a redistributor. Vortex breakers and collectors at the lower end of the column ensure reliable liquid drainage.
