Almost every unit operation process requires heating or cooling. Heat exchangers facilitate this without mixing the fluids.
An oil refinery uses the same and heat exchange operations, just with different temperatures and pressures. This philosophy allows for cross-industry innovation and standardized safety protocols. unit operation process

A unit operation process is a fundamental, discrete step in an industrial system—most commonly in chemical engineering—that involves a or transformation. Unlike "unit processes," which focus on chemical reactions, unit operations are the building blocks used to manipulate mass, energy, and momentum to prepare materials for reaction or to purify final products.
