Interesting approach, but what is the function of the COCl2 in this setup?
If it is somehow critical to the functioning of this method, it would be difficult to do safely for most amateurs.

Good eye phlogiston!
I guess is a typo for CaCl2.

Or perhaps this is supposed to be CoCl2 to refer to a dryness indicator in what looks like a drying tube?

I looked at my copy of Melissinos, it is older, I have this as Fig 5.15, it also says 'COCl2' but there is no discussion of this component in the text. I cannot imagine that this actually calls for COCl2.
