Shell & Tube Heat Exchanger Operation, System, Maintenance & Troubleshooting
Shell & Tube Heat Exchanger Operation, System, Maintenance & Troubleshooting
OBJECTIVES
• 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 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.
