Glass Process Equipment

Process equipment and production-scale reactor systems, consisting of glass-lined reactors with distillation overhead in borosilicate glass, can be operated at full vacuum and low pressure. Only highly corrosion resistant materials are in contact with process media, which allows a great variety of chemicals to be processed in such process equipment. These reactor systems are mainly used for pharmaceutical and chemical manufacturing, for processes including synthesis, distillation, rectification & solvent recovery, evaporation & concentration, extraction and crystallization. The design of the process equipment is either multi-purpose or process-specific. Feeders and receivers are made of glass for smaller volumes and of glass-lined steel for larger systems. Shell and tube type heat exchangers are built with inner tubes made of borosilicate glass, glass-lined steel, silicon carbide (SiC), Hastelloy®, tantalum or other metals, depending on process parameters and operational requirements. Process equipment and production scale reactor systems are always customized according to your specific process and space requirements.

Glass lined steel reactor: 250 - 10'000 liter
Pressure: -1.0 (FV) to +0.5 bar
Temperature: -60°C (-90°C) to +200°C
Material: Borosilicate glass 3.3 / glass lined steel / PTFE / PFA / Tantalum

Chemical process equipment, consisting of glass lined reactors or mixing tanks with distillation glass overhead are mainly used under vacuum for distillation, reflux distillation for different chemical synthesis and solvent recovery. Our 3-D engineering enables the integration of large glass lined reactors of different suppliers in combination with our glass components, forming a complete reaction system for production scale. Typically used in API and fine chemical synthesis. More information

Volume range: 63 to 1'000 l
Pressure: -1 to 6 bar
Temperature: -25 to +200°C
Material: All Thaletec glass linings available

Glass-lined reactors of Thaletec offer excellent resistance to corrosion, abrasion, pressure, water vapor, thermal shock, and wear. The reactors in the AE design are characterized by a main flange gasket with the same diameter as the total reactor. The system comes with an agitator system, baffle, sample extraction and several measuring probes (incl. conductivity, PT100, pH, etc.).

All type of glass-lined equipment from Thaletec, Pfaudler and De Dietrich can be reglassed if the glass-lining is worn, damaged or corroded. More information

Heat Exchange area: 0.6 - 23m2
Material: Borosilicate glass 3.3 / Silicon Carbide (SiC) / Hastelloy C22 / glass lined steel / PTFE / Tantalum / stainless steel
Pressure range cooling media: 3 - 10 bar

Heat exchangers are used for cooling and condensation, mainly in vacuum distillation, 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, often operated in combination with a secondary condenser for additional vapor condensation. More information

Glass column: DN 50 / 70 / 100 / 150 (up to DN600)
Flask size: 10 / 20 / 50 liter
Pressure: -1.0 (FV) to +0.5 bar
Temperature exhaust gas: -60°C to +200°C
Temperature scrubbing liquid: 0°C to +80°C
