all of the equipments here is of a larger scale than you can appreciate from coursework, or working at LANL, particularly in the labs..
This is kettle reboiler that we’re going to use for the methanol distillation column (shown in the foreground)
We removed the tube bundle (constructed from Admiralty Brass) for inspection

The tube inlets showed a little corrosion/scaling, but for their age (placed in operation in 1949), not too bad..
The kettle is a two-pass exchanger, with straight tubes and a confined volume for the return..
