Distillation and rectification columns - Import export

Glass overheads are typically built (in our standard chemReactor and production plant setups) for multipurpose and semi–batch operation mode under full vacuum. They mostly consist of feeder vessel, a distillation column, condenser and secondary condenser, phase separator, receiver, including valves and pressure equalization piping and a rupture disc as safety device. For rectification, packed distillation glass columns up to DN600 are used with reflux condenser, a reflux splitter with a reflux controller to set the reflux ratio. In Buchi chemReactors, both systems can be combined.

Glass distillation columns up to DN 600 are packed with random packing such as Raschig rings, ceramic saddles, PFA packing elements or structured packing dependent on the required separation performance and process media. Each packing type shows different separation performance, indicated by their number of theoretical stages. In combination with glass process equipment, highly corrosion resistant packing material is used for packed glass distillation columns.
