Is there anyone who specializes in design? Could you help me calculate the heat exchange area?

Cold medium: circulating water, with temperature and pressure in accordance with the specifications. Shell side (don’t ask me why; you can tell me why this choice was made): Hot material: carbon dioxide gas, cooled from 150°C to 40°C, 3600 NM3/H. (Pipe train) Heat exchanger: Fixed tube sheet type. Find the heat exchange area of the heat exchanger. It is used for comparison, so no high precision is required; an accuracy of around 20% is sufficient. Thank you, expert! ! ! !
What is the pressure of carbon dioxide gas?
It is estimated that the heat exchange area required is around 60 m2
Thank you:):lol:lol:lol:lol:lol:lol
At the very least, the operating pressure of CO2 should be indicated; the error is quite large. The selected material and heat transfer elements should also be specified; generally, shell-and-tube or finned-tube types are used. So providing a heat exchange area abruptly on the 3rd floor is pointless; even if the person asking is just trying to get a rough estimate, offering a value of 60 square meters is of no use at all. I once worked for a COFCO subsidiary on the replacement of imported equipment for CO2 water cooling; there were many requirements, including temperature drop, energy consumption, installation dimensions, and so on. . . . Later, an inward-fanning fin heat exchanger was chosen; those who are interested can browse the relevant posts on the forum: http://bbs.hcbbs.com/forum.php?mod=viewthread&tid=163192&highlight=%D6%B5%B5%C
