Book excerpt: This report presents a cost analysis of DL-Methionine production from methional and hydrogen cyanide (HCN) The process examined is a typical carbonate process. This process is a multi-step process including: hydantoin intermediate production; reaction of hydantoin with potassium carbonate to produce potassium methioninate; and methioninate conversion to DL-Methionine.
