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.

Heat exchangers are mainly used in vacuum distillation systems for cooling and condensation in the absorption and rectification processes in chemical plants. Glass heat exchangers enable visual process control during scale-up and production and processing of multiple (acidic) chemical substances. We offer glass spiral type and shell & tube type heat exchangers. These are often operated in combination with a secondary condenser for additional vapor condensation. The glass spiral heat exchangers can be operated in parallel to form large heat exchange areas for higher condensation performances and larger reactors systems in pilot plants. They feature easy cleaning and operation of cooling media at up to 3 bar pressure.

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.

The temperature of jacketed reactors can be controlled by TCUs (temperature control unit) large central heating/cooling units with secondary systems for individual reactor temperature control process steam (in case of large metal reactors) Our jacketed reactors are typically temperature controlled using heat transfer oil and TCU or central heating/cooling units. The heat transfer oil which is pumped through the jacket of the reactor controls the process temperature inside the reactor. The temperature range of the heat transfer oil spans from -80°C up to 300°C (depending on the heat transfer oil used).
