Could you please advise on how to calculate heat exchangers?

I know that for methanol with a flow rate of 40 m3/h, to heat it from 30°C to 60°C using saturated steam at 0.5 MPa, I need to know what size heating surface is required. Would it be possible to use a jacket surrounding the DN80 pipe for heating? Seeking advice
It’s time to review Chemical Engineering Principles thoroughly
Well, I’ll go look for the book; I hope to figure it out in one day
It’s not possible to simply add a jacket; the specific heat of liquids is much higher than that of gases, so using a jacket alone will not achieve the desired heat exchange effect. I used software to calculate the heat exchange area required for a shell-and-tube heat exchanger under the conditions you provided, and it’s around 13 square meters. Without considering heat transfer effects, if a DN80 jacketed tube is used, you will find that the required tube length will be very large; therefore, it is recommended to use a heat exchanger.
