Hi,
Is there a way l can add energy by using an energy stream on a certain stage on a complex distillation column? Thanks

Open the ChemSep GUI.
In Heaters/Coolers, add a stage heat exchanger.
To expose it as an energy (inlet-) port, on the CAPE-OPEN tab, check the "Expose Energy Ports" option.

Thanks did that, and specified the load, but if l hover over the ex duty energy stream on column 1, it shows work of 0 W. See attached file.

It is an input stream - you can change its value manually or connect it to something that will determine the value for you, such as an output stream of a heater or cooler that is set to heat or cool to a particular temperature.

i put the value when l inserted the stage under the heaters/cooler tab. i also tried to manually input a value of 2E6 BTU/H, I got an error message.

what error message?
If you put an energy inlet stream, its value overrides the value you enter in the GUI
