Suraj:

The manner in which I have always dealt with Unit Operations (and its counterpart, Unit Processes) is the following:

A Unit Operation is a process that results in a Physical Change - it depends on the same basic laws of physical science that applies to all other branches of engineering. Some examples are: separation of components (distillation, filtration, flotation, absorption, adsorption, etc.), heat transfer, transport of fluids, gas compression, evaporation, phase changes, etc., etc.

A Unit Process is a process that results in a Chemical Change - such as a chemical reaction or decomposition. This division of Chemical Engineering is more narrow and specific - however, it tends to be more complex and difficult. A nuclear reaction is a Unit Process; the subsequent utilization of its released energy into useful electricity is a series of Unit Operations.

If you desire a listing of all the possible Unit Operations out in industry, I recommend that you, as a student of Chemical Engineering, do a serious research using your text books and the Internet and develop one. This is an excellent preparatory tool for young students.
