Stirred-tank reactor Sistemas de reatores em escala de produção

for the chemical industryfor the plastics industryprocess

Overview
Buchiglas engineers and delivers complete production-scale reactor systems for chemical and pharmaceutical processes with nominal capacities from 250 to 10,000 L. Systems combine glass-lined (enameled) steel or Hastelloy® reactor vessels with borosilicate 3.3 glass overheads and the proprietary buchiflex flexible glass piping to meet cGMP and ATEX-related requirements.

Reactor summary
Type: glass-lined (enameled) steel reactor (DIN AE / BE type)
Volume range: 250 – 10,000 L
Pressure (glass distillation overhead): -1.0 (full vacuum) to +0.5 bar (higher reactor pressures possible using split-off valves)
Temperature range: -60 °C (down to -90 °C in special designs) to +200 °C
Materials: borosilicate glass 3.3, glass-lined steel, PTFE, PFA, Hastelloy® (C22/C276), tantalum, titanium, SiC

Technology and engineering highlights
Systems pair robust glass-lined or Hastelloy® vessels with borosilicate glass distillation heads to provide corrosion-resistant process paths and visual process monitoring at production scale. Design focus includes full customization of auxiliary equipment (dosing, weighing, solvent recovery), modular integration, short campaign changeovers and maintenance-friendly assemblies using buchiflex flexible connections.

Typical process equipment applications

• Chemical synthesis (organic & inorganic)
• Extraction & evaporation
• Purification & crystallization
• Distillation, reflux and azeotropic distillation
• Cryogenic / low-temperature reactions
• Solvent and acid recovery, recycling & purification
• APIs and HPAPIs
• Agrochemicals, fine & specialty chemicals
• Flavors, fragrances, pigments & dyes
• Detergents, coatings, adhesives
• Electronic and semiconductor chemicals
• Specialty polymers, battery chemicals, catalysts, precious metals

Key features & advantages

• Full customization: tailored integration of reactor, dosing pumps, weighing systems and auxiliary units to match process requirements.
• Flexible piping: buchiflex glass connection system (DN15 – DN150) for stress-free connections and rapid changeovers.
• Corrosion resistance: material combinations (glass-lined steel or Hastelloy®, borosilicate glass, fluoropolymers, ceramics) for aggressive media.
• Process visibility: borosilicate glass overheads enable visual monitoring at production scale.
