· Now, you'd think that distillation is one technique that is exclusively ours. Given the thermodynamics involved, I would tend to agree with you. However, the heart of the distillation column is the reboiler, unless you're operating directly on steam or another heat source. Even then, the boiler is in the wheelhouse of the mechanical engineer, as are the reboiler and condenser.
