We learned that heat is transferred if there is a temperature difference in a medium. Similarly, if there is a difference in the concentration of any chemical species in a mixture, mass transfer must occur. Mass transfer is mass in transit as a result of a difference in concentrations of a species in a mixture.[…]
In chemical engineering and its related fields, a unit operation is a basic step in a process. For this reason they can be classified in different ways. The first category assigned to UOs is mechanical operations. What they are, what their roles are, and what contexts they fall into, you will know in this episode.[…]
Heat transfer (or heat) is energy in transit due to a temperature difference. Whenever a temperature difference exists in a medium or between media, heat transfer will occur. This is the case in the unitary operations of this classification in the industries as a whole. Shall we delve into them? The study of unitary operations[…]
In an industry, starting from the raw material until reaching the final product, a series of processes must occur, some of them chemical and others of a physical nature.
