Heat exchangers, reactors, and towers are essential components in chemical, petrochemical, and processing industries. Heat exchangers facilitate the transfer of heat between two fluids, optimizing energy efficiency in heating or cooling processes. Reactors are vessels designed for chemical reactions, ensuring controlled conditions like temperature, pressure, and mixing to produce desired products. Towers such as distillation or absorption towers, are used for the separation and purification of mixtures based on differences in boiling points or solubility. Together, these systems play a crucial role in industrial processes, enabling efficient heat management, chemical transformations, and separation of substances.
