PEF2006 Gas Purification and Energy Optimization

Prerequisites

According to admission requirements.

Course Objectives

Get an overview of technological options to solve gas purification problems. Be able to select purification methods for a specific pollution problem and theoretical tools to choose processes and combinations of processes.
Get a survey of systematic methods of optimization of process plants. Be able to use these methods to calculate minimum energy, equipment area, equipment volume and total cost.

Learning Methods

Lectures and exercises.

Course Description

Global air pollution. Measurement of air pollution.

Purification methods for particles: Mechanical devices, wet scrubbers, filters.

Purification methods for gases: Absorption, adsorption, combustion, membranes. Regeneration methods: Distillation and desorption.

Energy optimization of CO2 removal.

Systematic methods for the generation of process flowsheets for new processes and the modification of existing plants. For this purpose, the process simulation tool HYSYS is used. Subtopics include the structure of separator systems, heat recovery and the design of heat exchanger networks (Pinch Technology), optimal utility systems, heat pumps, power production and economic trade-offs (investment versus operating cost).

Assessment Methods

The final test counts 70 % and tests/exercises 30 %.
