                    • Heat exchangers / condensers

                    • 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 heat exchangers 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.

                      Shell and tube type heat exchangers are used in combination with packed rectification columns as reflux condenser on larger systems. Buchi offers full glass and glass / silicon carbide (SiC) type heat exchangers with a 0.6 to 23m2 heat exchange area. SiC heat exchangers feature excellent thermal transfer, thus reducing the requested heat exchange area compared to full glass types which can reduce the requested space for the complete system. The optional safety chamber enables easy leakage examination and increases the operation pressures of the cooling media to 6 bar
                    • Distillation / Rectification

                    • 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.
                    • Distillation columns / Packing

                    • Glass 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.
                    • Ex stirrer drives, stirrer shaft seal

                    • A stirrer drive consists of:

                      Ex motor with ex proof speed reducer for manual speed adjustment or with a frequency converter for electrical speed adjustment and measuring of the stirrer speed and torque
                      Ex proof stirrer shaft seal keeping the reactor tight against the atmosphere and dry running to avoid any contamination of the chemical process and product
                      stirrers for best heat transfer into the product and efficient mixing of the chemical components

                      Stirrer drive with dry running mechanical sealing
                      The stirrer shaft seal is a key component of chemical reactors. It stands for leakage free operation of the rotating stirrer shaft. A mechanical seal shall be dry running, avoiding any contamination of the chemistry by a lubricant. Stirrers or agitators are important for mixing and heat-transfer so design and dimensions are crucial. Impellers are used for universal tasks

                      Mechanical sealing is designed for vacuum and low pressure and stirrer speed operations for larger glass lined steel stirrer shafts. These shafts are offered in corrosion resistant metal and ceramic for very high pressures and viscosities – see also our magnetic couplings below

                      Stirrer drives with dry running magnetic coupling
                      Dry running mechanical stirrer shaft sealing including stirrer, motor and control used for high vacuum to high pressure and high viscosities are equipped with magnetic couplings as a static sealing element. These stirrer drives for chemical pressure reactors are designed for extreme operating conditions regarding temperature, pressure, low and high torque mixing, high stirrer rotation speed. The wetted parts are made in corrosion resistant metals and ceramic.

                    • Buchi laboratory autoclaves and pressure reactor systems are used for reactions under pressure such as hydrogenation, polymerization, catalyst research and materials research in chemical laboratories. They are also used for small-scale production. The autoclave reactor can be operated with various interchangeable glass reactors made of borosilicate glass 3.3 or high pressure-, high temperature reactors made of metal. Corrosion-resistant metals such as stainless steel, hastelloy, tantalum, titanium, zirconium etc. are used, see corrosion resistant materials. Powerful agitator drives with magnetic couplings ensure efficient stirring and mixing even at high viscosities.

                                            • Sightglass metal & glass reactor

                                            • Understanding a process can be done by measuring and recording different process parameters. Of great importance can be changes, which are hard to measure, but which can be easily observed simply by looking at the reaction through the pressure vessels' glass wall or through a sightglass on metal reactors, designed for higher pressure.

                                              Buchi glass reactors for pressure applications can safely by operated at 6 / 12 bar pressure (85 / 165 psi) due to special design - and safety features. High pressure sightglass for steel / Hastelloy pressure reactors are available in a standard configuration up to 60, 100 bar, 250 bar.
                                            • Fast Action closure, reactor lift

                                            • Safe, fast and easy operation with the fast action closure

                                              If the pressure vessel is to be opened frequently, a fast action closure becomes very helpful. Our fast action closure solutions are manufactured and comply with the European Pressure Equipment Directive PED. Reactors can only be opened in unpressurized condition.

                                              Opening and closing the reactor becomes very easy and does not require any tool. With our vessel lift option even heavy reaction vessels can be opened and closed without the need of attending multiple gym lessons beforehand.

                                              Nut and Bolt closure of the reactor is the more economic version. It is often the choice picked if reactors are not opened frequently.

                                              The Reactor Lift is very convenient for the operation of heavier pressure vessels. It is available for Nut and Bolt closure as well as for Fast Action Closures.

                                            • Temperature control of pressure reactors in Lab and Pilot Plants
                                              Accurate temperature control of chemical reactors is important for the chemical process as well as for safety reasons (on exothermic reactions especially).There are 2 ways of accurate temperature control of chemical pressure reactors:

                                              Electrical heating for pressure reactors

                                              In case of electrical heating, heating elements are integrated in the temperature control block (limbo and limbo li high temperature / high pressure reactors) or on other Buchi pressure systems on the reactor itself. Integrated cooling coils can be connected to water or compressed air. The Buchi btc PID temperature controller ensures accurate process temperatures and efficient heating. This temperature control systems is used on Lab - and Pilot scale pressure reactors made of stainless steel, Hastelloy and other metals. It is also available in (ATEX) Ex version.

                                              The typical temperature range is from room temperature up to 500°C.

                                              Temperature control units (TCU) used with jacketed reactors

                                              TCUs are used for accurate temperature control in combination with jacketed reactors. By circulating a heat transfer oil through the reactors jacket, efficient heating and cooling of the process media as well as stable process temperature is achieved. Temperature control with TCUs is used for chemical reactors made of glass, glass lined steel, but also made of stainless steel, Hastelloy and other metals.

                                              TCUs installed outside of the Ex zone, connected to reactors inside Ex Zone 1 or 2, require an additional Buchi isolation barrier. For large TCUs, see also glass equipment, auxiliary equipment.

                                              Chemical reactors can be operated by TUCs with heat transfer oils of different temperature ranges from -80°C up to 300°C - info on request. Typical operation temperature: -50 °C to +250 °C

The proposed reactor was competitively priced and met our technical specifications. For Novan, the materials of construction (Hastelloy®), minimalization of dead volumes, pressure / temperature ratings, and vessel capacity were the most critical requirements. Advantages of Büchi include responsiveness of the local distribution partner, transparency during the equipment build in Europe, and effective installation/trouble shooting. Novan is very satisfied with the Büchi high pressure reactor and, in fact, we ordered a second unit during Q2 2017.

                                              • This innovative Parallel Pressure Reactor System was developed upon request from DOTTIKON EXCLUSIVE SYNTHESIS AG ("DOTTIKON"), the Swiss-based specialist in hazardous reactions. DOTTIKON needed a powerful system to test different reaction conditions for catalyst reactions under high pressure as an important prerequisite for a reliable and effective scale-up of chemical processes to large scale production.

                                                It was a joined effort by three specialists that brougth about the successful development of such a sophisticated tool.
