【3D Process Flow】Summary Post – Useful for learning about the process flow: https://bbs.hcbbs.com/thread-5711616-1-1.html ---------------------------------------------------------- Molecular sieve tower: The molecular sieve tower is an important separation device in the chemical industry; it utilizes the selective adsorption properties of molecular sieves to achieve efficient separation of mixtures. Molecular sieves possess a regular crystal structure and uniform pore sizes, enabling selective adsorption based on differences in molecular size, shape, and polarity. The process flow typically includes three main stages: adsorption, regeneration, and cooling. The feed gas/liquid passes through a molecular sieve bed, during which the target component is selectively adsorbed ； After saturation, it is regenerated by heating or reducing pressure to restore its adsorption capacity ； After cooling, it is reintroduced into the adsorption cycle. Molecular sieve towers are widely used in processes such as gas drying, dehydration, desulfurization, decarburization, and hydrocarbon separation.
