For a new process to recover natural gas liquids (NGL), I am designing a heater with hot compressed natural gas on the tube side and NGL on the shell side. The NGL will vaporize forming a two-phase mixture. The heat exchanger is a simple one pass shell and tube design. Should the NGL enter the bottom and flow out the top or just the reverse? Also, are vertical baffle's recommended?

Thank you.
 
Boiling fluids should always go up and condensing fluids down. As a chemical engineer, we do not specify the direction of flow on the data sheet. A mechanical engineer using HTRI or HX vendor would recommend the arrangement. We would just verify.

With respect to vertical baffles on the shell side, these would be specified by mechanical/vendor, however if mechanical/vendor requires baffles, the baffles should be designed such that there are no pockets for vapor to be trapped.
