Automatic and Continuous Measurement of RTD Parameter

 

Residence time distribution (RTD) refers to how long fluid elements stay in a reactor. In a flow chemistry reactor, the residence time differs from that of a batch reactor due to factors like uneven fluid velocity, fluid diffusion, and dead zones in the reactor.

RTD measurement is crucial in chemical reaction engineering and separation processes, serving as a key basis for reactor design and operation. In the FDA's "Guidance Principles of Quality Considerations for Continuous Manufacturing," process dynamics in continuous production are discussed, focusing on material traceability. RTD parameters play a vital role in material traceability and the development of effective sampling plans for managing continuous manufacturing processes.

This tool automatically calculates the reactor's RTD value under specific conditions using pulse tracing and built-in algorithms in the software. It offers valuable data for reactor design, selection, and process improvement. The device includes a high-pressure pump, an automatic sample collector, a microreactor platform, an inline UV spectrometer, and management software system.

Features

  • Automatic and continuous measurement of RTD

  • Liquid flow rate and temperature can be edited according to the characteristics of the reactor

  • Highly sensitive inline UV-Vis spectrometer 

  • Integrated design and solutions
