Reaction vessel v Steam pressure

Click For Summary

Discussion Overview

The discussion revolves around the design and safety considerations for a reaction vessel with an inbuilt condenser. Participants explore the necessary calculations and regulatory requirements to prevent failure due to internal pressure during operation, touching on aspects of mechanical engineering and compliance with standards.

Discussion Character

  • Technical explanation
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • Adrienne seeks assistance in calculating elements to ensure the reaction vessel does not fail under pressure, indicating a lack of prior knowledge in physics.
  • One participant emphasizes the importance of adhering to regulations set by the British Standards Institution regarding pressure vessel design, including material and construction standards.
  • Questions are raised about the intended thermal capacity, pressure, type of reaction, and source of thermal energy within the vessel.
  • Another participant suggests that the basic shape of the vessel might be spherical, although this is not confirmed.
  • There is a suggestion to create a specification for a custom pressure vessel manufacturer, highlighting the need for a qualified engineer to design the overall process involving the vessel.
  • Adrienne expresses gratitude for the questions posed, indicating that they will inform her research and design process.
  • A participant shares frustration regarding the certification process in Texas, mentioning difficulties in obtaining guidance from ASME and expressing concerns about the implications of not being certified.

Areas of Agreement / Disagreement

Participants generally agree on the necessity of compliance with local regulations for pressure vessel design and the involvement of qualified professionals. However, there are varying levels of understanding and experience regarding the certification process and the specific requirements for the design project.

Contextual Notes

Participants have not fully addressed the specific technical requirements or calculations needed for the reaction vessel, and there are unresolved questions about the design specifications and operational parameters.

Hello folks

I am building a reaction vessel that will have an inbuilt condenser for a design project at the Saint Martiin`s school of fashion in London. Problem is, I know nothing about physics. would anyone help me out on what and how I calculate the necessary elements that will prevent the vessel from popping with internal pressure once its being used.

Much appreciated,
Adrienne

This is not a trivial problem and the design and construction of pressure vessels must comply with strict regulations, which I believe is maintained by the British Standards Institution, Pressure Vessel Design Committee. The standards would have requirements on materials and dimensions, and construction, which include welding procedures.

What is the intended thermal capacity and pressure?

What reaction will take place in the vessel? What is the source of thermal energy?

Where is the condenser located?

Pressure vessel design, construction and operation are really mechanical engineering, not physics.

That is quite a project. I am assuming its basic shape will be spherical?
 
As Astro' points out, any pressure vessel must comply with local laws that regulate them. You can't design and build your own without being legally certified to do so.

I'd suggest you create a 'specification' which tells a custom pressure vessel manufacturer (of which there are many) what it is you want. You also need to consider how this vessel will be used in service. It seems like the entire process you will be putting it into must be designed, or perhaps I've missed that point. Don't know. Anyway, the process into which this vessel is going must also be designed by a qualified engineer/manufacturer.

Can you be more explicit in what you want? If so, perhaps you can get the help you need here to get started on a draft copy of a process and pressure vessel specification which could be competitively bid on by various qualified manufacturers in your area.
 
Hello

As a quick reply I am very thankful to you guys. All those questions are already very helpful in what my research will have to go into. I am on the drawing aspect of it and will have to work in conjunction with the especialists in what the topics you rose are. Just trying to be ahead of the game as a good student. Shall come back with the answer for your questions.

You are lovely.
Adri

yes very frustrating even calling the ASME they could not tell what I needed to do to become certified (I live in Texas). I know they offer all kinds of training on section VIII. etc. Put if I don't get certified this seems to be more for sh#ts and giggles.

Any suggestions Goest?
