How does pervaporation membrane work?

The separation mechanism of pervaporation membranes is mainly a dissolution diffusion process, which is a membrane technology that uses dense polymer membranes to separate the components of liquid mixtures and dissolve diffusion properties.

Why is pervaporation membrane attracting attention?

Why is pervaporation membrane attracting attention?

The pervaporation membrane evaporation process (referred to as PV) is the process of selectively absorbing and decomposing components in a mixed solution and the diffusion rate of each component in the membrane to separate or enrich a portion of an organic mixture. Its outstanding advantages: it can achieve separation tasks that traditional methods such as distillation, extraction, and adsorption are difficult to complete, with low energy consumption, and is particularly suitable for near boiling point, constant boiling point mixtures, and the same detonation structure. It is difficult or impossible to separate through ordinary rectification. And separate compounds with poor thermal stability. The removal of trace amounts of water in organic solvents and mixed solvents, as well as the separation of small amounts of organic pollutants in wastewater, has significant economic and technological advantages. It has been widely used in many industrial fields such as petroleum, chemical, pharmaceutical, and environmental protection.

What is a pervaporation membrane and what are its characteristics

Pervaporation process (PV) is the process of separating or enriching a portion of an organic mixture by utilizing the selective absorption and desorption of each component in the mixed solution by a polymer membrane, as well as the different diffusion rates of each component within the membrane. Its outstanding advantage: it can achieve separation tasks that are difficult to complete by traditional methods such as distillation, extraction, and adsorption with low energy consumption, especially suitable for the separation of near boiling point, constant boiling point mixtures, isomers, and compounds with poor thermal stability that are difficult or cannot be separated by ordinary distillation. The removal of trace amounts of water from organic solvents and mixed solvents, as well as the separation of small amounts of organic pollutants from wastewater, has significant economic and technological advantages and has been widely used in many industrial production fields such as petroleum, chemical, pharmaceutical, and environmental protection.

What is an organic solvent?

Solvents are divided into organic solvents and inorganic solvents based on their chemical composition. It is a large class of organic compounds widely used in daily life and production, with a small molecular weight. It exists in coatings, adhesives, paints, and cleaning agents. Organic solvents are often used. What are organic solvents?
