The Course

Heat exchangers are important and expensive items of equipment that are used in a wide variety of industries. A better understanding of the basic principles of heat transfer and fluid flow and their application to the design and operation of shell and tube heat exchangers as well as plate heat exchangers, air cooled exchangers and other specialty heat exchangers that you gain from this course will enable you to improve their effectiveness and extend their life.

The course provides in depth presentation of the main types of industrial heat exchangers, their key features and aspects, and provides practical guidelines for selecting the appropriate type for specific applications.

You will better understand how to use the applicable API, TEMA and ASME codes, standards and recommended practices. Discussions cover fabrication, materials of construction and costs of tubular units; condensers and reboilers; effect and mitigation of fouling; and causes and prevention of exchanger tubes vibration and damage.

The workshops include practical worked examples to reinforce the key learning.

The Goals

The objectives of the course are:

·         To highlight the pivotal function and significance of heat exchangers in cost-effective plant operations

·         To provide a clear understanding of the fundamentals of heat transfer and hydraulics and fluid flow and their application in the thermal design of heat exchangers.

·         To provide methodologies for the mechanical design of heat exchangers in accordance with industry codes, standards and best practices, specifically ASME BPVC Section VIII, TEMA, and API 660, 661, and 662.

·         To make delegates aware of cost-effective technologies and best practices for improving performance of heat exchangers

The Delegates

The course is intended to benefit project, process, mechanical and plant engineers as well as operations and maintenance managers and supervisors involved in the design, operations, troubleshooting and maintenance of heat exchangers and energy conservation in the oil, chemical, power, and other industries. The detailed review of mechanical design is particularly useful to plant and maintenance engineers. The course will be also beneficial to recent engineering graduates.

No prior knowledge of heat transfer is required. Participants will be taken through an intensive primer of heat transfer principles as applicable to shell and tube heat exchangers.

The Process

The course is comprehensive and highly interactive. It combines structured and focused presentations and discussions of topics covered with actual relevant examples. It combines sound engineering principles, methods, and applicable codes & standards and best industry practices with workshops that cover worked examples to enforce the learning. To maximize learning, optional Question & Answer sessions are available at the end of each day to avail participants the opportunity to ask questions relating to topics discussed and specific heat exchanger problems they may experience.

All delegates will receive a complete set of all course presentations as well as detailed lecture notes which will provide an invaluable reference document.

The Results

The company will achieve improved financial performance through the proper selection and application of the appropriate type of heat exchangers that achieve optimum balance between capital investment and energy costs.
