Process Systems Analysis:

Process Systems Analysis CHEM2002 1

COURSE DESCRIPTION AND RATIONALE:

COURSE DESCRIPTION AND RATIONALE This course builds on the first semester course CHEM2001 where mass and energy balances were written for a single unit or simple combinations of units and solved using manual approaches and packages such as Aspen-HYSYS. The more advanced approaches, tools and methodologies used for systems analysis of processes involving many unit operations and unit processes are introduced in this course. The analytical skills developed in this course are the foundation for further work in the third and fourth year unit operations, process synthesis and process design courses. The scope and overall setting of the process industries and process engineering are also investigated. This course aims to give both the “big picture” for process industries and systems as well as insights into detailed analysis of process systems. 2

INTENDED LEARNING OUTCOMES:

INTENDED LEARNING OUTCOMES List key operating & design parameters & equipment selection criteria for a limited set of unit operations. Explain the techniques used in flow sheeting and analyse different flowsheets. Draw block diagram and corresponding Aspen-HYSYS diagram from a process description Determine the economic potential of a process and to identify the operational variables that affect the economics at input-output structure level. Determine the degrees of freedom for the process and when solution of the material and energy balances is possible. Determine suitable decomposition and tear structures to solve for material and energy balances for processes with recycles. Do partitioning and precedence ordering for different flowsheets. Simulate and critically interpret a sizeable process flowsheet using the Aspen HYSYS simulator. Work effectively in an engineering project team 3
