Why is destallation not used very often?

Destillation is not used very often due to its high energy consumption and operational costs, particularly for large-scale separations. Additionally, it is less effective for separating mixtures with close boiling points or azeotropes, which can complicate the process. Alternative separation methods, such as membrane filtration or adsorption, are often more efficient and cost-effective for specific applications. These alternatives can offer better selectivity and lower environmental impact.
