How to represent cold boxes in PID and PFD
Thread Content
I’m seeking help from experts regarding how to represent a cold box in PFD diagrams, as well as the control mechanisms involved in PID diagrams
I’m here to learn *; please, experts, answer quickly! ! !

It’s not included in the legend for chemical and petrochemical process diagrams; I’m not sure if it’s available for fine chemicals.
For drawing, refer to \"JB/T 7672-2010 Diagram Symbols and Text Codes for Process Diagrams of Air Separation Equipment\"; other aspects are the same as those used in chemical process PID diagrams~~
Cold boxes are generally not shown in PID and PFD diagrams
I took a look, and there were drawings on how to draw cold boxes:'(
I’m sorry for the mistake; I didn’t see any illustrations regarding the construction of cold boxes
The inside of the cold box is a multi-channel structure; I’m not sure what processing method you use. For a PFD, you just draw a square, include several plate fins and flow channels connected in series, and indicate the name of the fluid. That’s it. A PID is just a few more components. It’s not possible to upload actual images; otherwise it would be possible to see them visually.
1158227124@qq.com is my email address. Could you send me the actual images? :D We are working on the process of producing propylene through propane dehydrogenation, and there’s a cryogenic section involved; I’m not sure how to represent it properly. :(
Are you working on design? Still a student? A graduation project?
