Processing almost needs a flow chart for the options branching at:
- Glyc prewash/dewater
- AAF/venturi/pump in Methoxide
- Single stage/two stage
- WBD or not
- Prewash or not
- Demeth by condensor/wash out Meth/bubble out Meth
- Settle/water wash/dry wash
- Filter or not

In some ways it's good - we have a lot of choice!
