"unit operation" is one step in a process to convert a raw material
into some useful chemical product. It's one of the blackboxes
which appeared in process and performs some physical (as opposed
to chemical) change. In this course, we will learn staged separation
techniques and how to design equipment for distillation (usually
tray towers), liquid-liquid extraction and leaching. You will
know and understand the operation of distillation columns, leaching,
and extraction equipment.
