Hi,
Currently i am designing a vacuum distillation column to separate glycerol from propylene glycol, however i need to be able to simulate and design how the vacuum is actually created in the column, through research and advice ive been informed that the vacuum is created through vacuum pumps and stem ejectors, and when i looked online i saw the primary use of oils and a fired heater to before the column. So im asking whether i need to incorporate oil and steam into my design or just vacuum pumps, because i am not cracking oil.
Thanks
