US Patent 12011677 Process for evaporating water from stillage

This disclosure describes energy efficient process to distill a process stream in a production facility. A process uses multiple effect evaporators, ranging from one evaporator to eight evaporators in each effect. The process arrangement shows an example of four effect evaporators, with a zero-effect evaporator having a single evaporator, a first-effect evaporator having a set of three evaporators, a second-effect evaporator having a set of three evaporators, and a third-effect evaporator having a set of evaporators to create condensed distillers solubles.
