Reactors for Crystallization, Precipitation, and Solid Formation Processes

Why Crystallization Processes Require Specialized Batch Reactors

Crystal formation is governed by supersaturation, temperature gradients, nucleation rates, and growth kinetics. Subtle variations in thermal control and mixing can shift particle size distribution, filtration performance, and downstream processing efficiency. Solvent compatibility and controlled cooling profiles are critical to product consistency.

Frequently Asked Questions

Q: What materials are available for crystallization reactors?

A: We offer carbon steel, 304 and 316 stainless steel, duplex stainless steels, Hastelloy, Inconel, titanium, and other alloys selected for solvent, corrosion, and temperature compatibility.

Q: What sizes do you manufacture?

A: We manufacture reactors from pilot scale (50 gallons) through production scale (15,000+ gallons). Custom sizes are engineered to your specifications.

Q: What pressure and temperature ratings are available?

A: Standard designs accommodate pressures from full vacuum to 5,000 psig and temperatures from cryogenic to 1,000°F. Higher ratings are available for special applications.

Q: Do you provide engineering support for reactor specification?

A: Yes. Our engineering team works with process engineers to specify optimal reactor design including materials, heat transfer, mixing, and instrumentation.

Q: What is typical lead time for batch reactor manufacturing?

A: Lead times typically range from 16-24 weeks depending on size, materials, and complexity. Expedited schedules can be accommodated for urgent requirements.
