Unit Operations Petrochemical Plant I

At the end of this course, the students should be able to: 1. explain the principles of separation processes; 2. explain the characteristics, applications and rating problems relative to the unit operations mentioned in the

for steady and unsteady state, batch and continuous, stage- continuous contact operations; 3. discuss the regimes for the flow in tubes and pipes, Bernoulli's equation, pressure drops, pumps, elements of external flow (Stokes' and Newton's law); and 4. apply the different methods of solid-liquid separation using the units’ operations listed in the course content; * It is expected that 2hrs every week should be used by students to learn how to use software such as CHEMCAD, HYSYS for simple calculations based on the content of this course.
