Definition
- Verb:
- To cause a liquid to evaporate through a semipermeable membrane: This refers to the process of separating components of a liquid mixture by forcing it through a membrane where one component vaporizes more readily.
- To evaporate through a semipermeable membrane: This describes the action of a liquid component passing through a membrane in vapor form.
Usage
The verb "pervaporate" is a technical term used primarily in chemistry and chemical engineering. It describes a specific separation process. It is typically used in the active voice (to pervaporate something) or in the passive voice (a substance is pervaporated).
Examples
- The laboratory set up a system to pervaporate the water from the ethanol solution, effectively dehydrating it.
- In this membrane module, the organic solvent will pervaporate, leaving behind the heavier contaminants.
- The separated component was successfully pervaporated through the polymer membrane.
Advanced Usage
- Pervaporation Process: The industrial-scale application of pervaporating mixtures, often used for dehydrating solvents or removing volatile organic compounds from water.
- The plant uses pervaporation to produce high-purity biofuels.
Variants and Related Words
- Pervaporation (n): The technical name for the process or technique of pervaporating.
- Pervaporation is an energy-efficient separation method.
- Pervaporative (adj): Relating to or involving pervaporation.
- The pervaporative properties of the new membrane were tested.
Synonyms
- Membrane-evaporate (technical synonym, less common)
- Selectively evaporate (descriptive synonym)
Notes on Meaning
This word has a very specific, technical meaning related to a physical separation process. It is not used in general language. Both of its core definitions describe aspects of the same scientific phenomenon.
Verb
