Thank you so much. It was very helpful.

Hello everyone, I am designing a cyclone filter with a flat top though which a large nozzle passes. The cyclone is working in full vacuum condition with zero internal pressure at a design temperature of 200°C. The calculated thickness for both drum and conical section is 8 mm. Material is...

A vacuum pump is considered for each shell to extract the non-condensibles. I guess that does the job.

First, thank you very much for sharing these contents. That was so nice of you. Second, from what you said about overall heat transfer coefficient, I guess this is not an efficient design, is it? Maybe to opt for another type of exchanger?

From the beginning I've had this dout that the mass flow rate of steam was reported incorrectly. I'm still not sure if the client is entirely confident about these numbers. However, we decided to give them our technical offer based on our own design.

I'm sorry, I can't find this parameter in the software report. However, I uploaded the latest design (4 parallel shells) report. I would appreciate if you could find any time to check it out. The tubes are split somewhat equally in a mixed H layout. The steam line works at vacuum pressure. The...

Well, where I’m from, they expect you to be a jack of all trades! 😅 We’re an engineering company and manufacturer, but most of our work revolves around mechanical design rather than process engineering. Cases like this one don’t come our way very often. BTW, Here’s an update on the...

Thanks a lot. I just needed to make sure there is something off with the provided data. And I guess we have to present them our own design as you suggested. Whether they accept it or not is their own decision. As to tube thickness, it's a common choice for high alloy steel among our business...

Hello everyone, I’m a mechanical engineer working for a vendor that designs and fabricates heat exchangers. While we primarily focus on mechanical design, clients sometimes ask us to guarantee thermal performance as well. This usually involves minor tweaks in HTRI, like adjusting tube layouts...

Thank you very much, both you guys! So as I understand the first interpretation in my original post is to be followed. Again, your insight and input is very much appreciated.

Hi, I have a problem understanding this clause from Appendix 13 of Sec VIII regarding the stress calculation for a rectangular vessel with more than 3 compartments. The part of the clause in question says: 13-9 (f) (2): "... For a vessel with more than two compartments, use geometry shown in...
