Shell and Tube Heat Exchanger

Shell and Tube Heat Exchanger

OBJECTIVES

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 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.

WHO SHOULD ATTEND? 

Project engineers, process engineers and plant engineers, mechanical engineers involved in design, operations, troubleshooting and maintenance, supervisors, technicians and technologists in the oil, chemical, power, and other industries that 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.
