Natural Gas Liquid Heater Nozzle Configuration

Natural Gas Liquid Heater Nozzle Configuration

Natural Gas Liquid Heater Nozzle Configuration

(OP)
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.

RE: Natural Gas Liquid Heater Nozzle Configuration

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.
