Abstract
Processes for the separation of water from a mixture of water with other components, comprising the following steps: A) providing feed material FM comprising water and at least one a nonionic surfactant S in an amount of 0.1 to 1000 ppm by weight based on the feed material FM, B) subjecting said feed material FM to a distillation step using a falling film evaporator.

A process for separating water from a mixture of water with at least one other component, the process comprising:
- providing a feed material comprising water and at least one nonionic surfactant in an amount of 0.1 to 1000 ppm by weight based on the feed material, and carrying out distillation of the feed material with a falling film evaporator, wherein the at least one nonionic surfactant is a polyalkylene oxide (PAO), wherein said PAO comprises a copolymer of at least two different types of alkylene oxides, and wherein said PAO is optionally functionalized at its terminal hydroxyl (OH) positions.
