Introduction :
Fluids and fluid movers such as pumps, compressors of various designs and applications, are encountered throughout chemical and process industries, including oil refineries, gas production facilities, power generation and other fields of engineering. As fluids can be in-process material in the form of liquid, gas or a mixture of both with solids, corresponding pumps and compressors sometimes have to satisfy high demands of efficient transport of complex and difficult fluids. The progress in the design and application of pumps, compressors and turbines has been so rapid that currently, all limitations of pressure, capacity, temperature, and nature of fluids have disappeared. At the same time, this advance in construction and application has presented numerous problems: mechanical, hydraulic, operating, economic, etc.
A thorough understanding of basic principles of fluid flow in pumps, compressors and turbines as well as in piping systems is a prerequisite for successful design, installation and operation of these machines. Various numerical examples are selected carefully to be from real-life technical practice, and will help remove any misconception reflected in an inefficiently operating piping system. Design and operation of gas turbines due to their complexity, require special attention and information on their interaction with axial compressors.
Highlights of the course include:
- Principles of selection of the right pump, compressor and turbine for the given application
- Practical issues related to trouble-free functioning of pumps, compressors and turbines in various industrial applications
- A good blend of comprehensive explanations of fundamental principles of fluid flow and valuable empirical industrial experience gained over the years in operation and service
- Guidelines for installation, operation and maintenance with the procedure to diagnose and solve problems in operation with troublesome fluids
- Economical issues: cost and benefit analysis
