Gents,

The step down in temperature you's propose from h2 through h3-1, h3-2, h3-3 to h3-4 (chefs ph chart)

How is this being achieved ???

Does your proposed vessel have multi-stages & as you remove vapour at each stage your lowering pressure each time, lowering the liquid temp ???

I am trying to follow closely & quietly, just I am getting a bit confused

Also what is the correct way to write the part in bold ???
