I don't believe there is a "one size fits all" when it comes to flow sheets. Lepidico's process if sulfuric acid heavy, and it does rely on being able to be close to industries that can adsorb the by-products to make it "zero waste".

EMH at the time decided that the process via Anzaplan better suited their needs at the time. The thing I find interesting, is they released a PFS in 2017, but still have not released a DFS, or C02 emissions. The CO2 emissions is due Sept qtr 2021 (ie overdue). It will be interesting to see where they fit.

Back in 2017, the price of carbon was low. The price is increasing. I am reading that companies should be planning to pay $100-$200 USD/tonne. If you have a process that is 15t CO2/t LCE, then that adds potentially $1500USD/t. If an alternate process if 3t CO2/t LCE, then difference is $1200USD/t. It starts to be a major cost.

Price of carbon is key IMO

That said, they could modify their flowsheet and have a roast in the front end, some carbon capture, incorporate LOH-Max in the backend and then produce Carbonate. Could be a compromise
