Continuous Industrial Processes Over 24 hours

Click For Summary

Discussion Overview

The discussion centers on identifying continuous industrial processes that involve the synthesis of a product or material taking over 24 hours for a specific stage. Participants explore examples and considerations for designing a continuous process with long reaction times, specifically aiming to avoid extensive pipeline use.

Discussion Character

  • Exploratory, Debate/contested

Main Points Raised

  • One participant inquires about continuous processes in industry that have a synthesis stage lasting over 24 hours.
  • Another participant mentions a local beer microbrewery, noting that some steps in brewing take a day or two, questioning if this aligns with the original inquiry.
  • A subsequent reply clarifies that brewing is a batch process, not continuous, which is a key distinction in the discussion.
  • One participant expresses skepticism about the feasibility of continuous processes with a residence time over 24 hours, suggesting that such processes would require very large equipment.

Areas of Agreement / Disagreement

Participants generally agree on the need for a continuous process but disagree on the applicability of brewing as an example, with some expressing doubts about the practicality of continuous processes with long residence times.

Contextual Notes

The discussion does not resolve the feasibility of continuous processes with long reaction times, and assumptions about equipment size and process design remain unaddressed.

Hello all,

I am wondering if anyone is aware of any continuous processes currently in industry that involve synthesizing some kind of product or material, but takes over 24 hours?

I don't mean the entire process itself takes 24 hours or more, but a certain stage of the process, such as the synthesis of desired compound(or product) before it is further processed (dried, distilled,etc.) takes over 24 hours.

If you are aware of such a process, please inform me. I am brainstorming ways to design a continuous process with reactants that take arounf 72 hours to react, and I am trying to avoid using miles of pipeline


Thanks

I recently took a tour of a local Beer Microbrewery, and several steps in the process of brewing beer took on the order of a day or two. Is that along the lines of what you are looking for?
 
Yes, any process that takes over 24 hours and is yet remains continuous is along the lines of what I'm looking for. Was this a continuous process or a batch process?

Ah, sorry. I missed the subtlety of the word "continuous" process. Beer making is a batch process.
 
I think if the residence time is over 24 hours, it would not make sense to use a continuous process, since the equipment would need to be very large.
