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 fluid flow and heat transfer and their application to the design and operation of shell and tube heat exchangers as well as compact and air cooled exchangers that you gain from this course will enable you to improve their effectiveness and extend their life. 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 learnings.
¢ To understand the significance of heat exchange in the refining and process industries and how to optimize heat recovery.
¢ To review design features and standards for heat exchangers with emphasis on shell-and-tube heat exchangers.
¢ To discuss techniques of failure prevention and appropriate maintenance procedures.
¢ To provide information that will enable decisions to be made on the repair and refurbishment of aging equipment.
¢ To delineate the factors that lead to overall economically advantageous decisions.
Who Should Attend
Project engineers, process engineers and plant engineers, facilities engineers, mechanical engineers involved in design, operations, troubleshooting and maintenance, supervisors, technicians and technologists in the oil, chemical, power, and other industries who require a wider and deeper appreciation of heat exchanger design, performance and operation, coupled with the use of computers. The detailed review of mechanical design is particularly useful to plant and maintenance engineers as well as to those generally knowledgeable in the subject, but who require a refresher or update. 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.
This is an intensive and interactive course in which participants are drawn into discussions to facilitate learning.
