I am designing Vaporizer of 100 kg/hr, I have attached the LPG(Propane) Vaporizer Design, and reference for the same is taken from Dennis Moss, Pressure vessel design manual. Please verify the design for its correctness. Please refer Rev.0 worksheet.


The LPG Vaporizer is with electric Heater, I haven't included the electrical heater calculation part.

What pressure are you operating at?  1 atm looking at the required outlet temp.  


Your heat balance seems incorrect, missing latent heat?  I get approx 236,000 Btu/hr based on your mass flowrate.  


Electrical heater sizing would be the heat required + an excess for safety.  I'm assuming this is a coil in a water bath?

It would probably be simpler to use an ambient air vaporizer. We never design such an item. But provide a specification to vendors who will provide such items.
