Reflux column size
Bro
Im new at recovering methanol, i always evaporate.
I saw your methanol recovery unit. And i was amazed..
I want to build two stainless steel units for demething bio, and other one for recovering from glyc.

The bio demeth unit is for 1,000 liters.

The tank is gonna be 100 cm diameter and 155 cm tall. So its a 1,200 liters tank.
I wanted to ask you.
What diameter and height size would you recommend for the column.
How much KW for heating?
Should i pump the liquid, bubble air or just let the element heat until evaporates?

The glyc unit is for 400 liters of glyc (i use KOH).
The tank is gonna be 80 cm diameter and 100 cm tall si its a 500 liters tank.

Marbles is the best option for higher purity?

Whats the best type of tank? taller thiner tanks, conical, box type tank, horizontal tank?

Would you recommend whole batch demeth instead in one larger tank?
I dont like mixing things, and trying to avoid stechiometric point is gonna leave small amounts of methanol on biodisel after WBD, same case for glyc.

Any advice would be really helpful.

Thanks.
