Overview

Heat exchangers are devices designed to transfer heat between two or more fluids—i.e., liquids, vapors, or gases—of different temperatures. Depending on the type of heat exchanger employed, the heat transferring process can be gas-to-gas, liquid-to-gas, or liquid-to-liquid and occur through a solid separator, which prevents mixing of the fluids, or direct fluid contact. Other design characteristics, including construction materials and components, heat transfer mechanisms, and flow configurations, also help to classify and categorize the types of heat exchangers available. Finding application across a wide range of industries, a diverse selection of these heat exchanging devices are designed and manufactured for use in both heating and cooling processes.

This training focuses on heat exchangers, exploring the various designs and types available and explaining their respective functions and mechanisms. Additionally, this training outlines the selection considerations and common applications for each type of heat exchanging device.

Objectives

At the end of this training you will be able to learn how :

  • 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 participants 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.
