Process Technology Equipment and Systems 4th Edition
It should come as no surprise to anyone who knows the important role process technicians play in modern chemical manufacturing to discover the prominence thatprocess technology programs have taken in U.S. and international community colleges and universities. Still, the controversial question remains, “what is process technology?” Process technology is a field of study offered at community colleges or universities that prepare students to take entry-level positions as technicians in the chemical processing industry. The curriculum can be categorized as the study and application of the scientific principles associated with the operation and maintenance of the CPI. Typically, there are 8 to 12 core classes that cover theory and hands-on operation, including safety, quality, equipment, instrumentation, physics, chemistry, math, process systems, unit operations, and troubleshooting. Hands-on training may include drawing P & IDs, operating bench- top units, starting-up, operating, and shutting down DCS simulations and small scale pilot plants. The first process technology program was offered at a Jr. college in Baytown Texas in 1938 by employees of Humble Oil, now Exxon Mobil.
This text is the product of many years of research in the field of process technology and operator training. It is unique and designed to enhance the learning sequence needed by adult learners. The materials in this text are the foundation topics for operator training. Educators, of course, do their best to provide well-thought-out and illustrated textbooks, classroom lectures, computer-aided simulations and instruction, hands-on activities, bench-top and pilot units, CD/DVD materials, and the like. They take into consideration learning styles/strategies and find teaching approaches that work best—that is, how both an instructor and an individual approach the learning process and, given my experience in teaching process technology, there is a marked preference for teachers and students alike to emphasize self-study, of being responsible for this discipline on their own. This is the approach taken in the fourth edition of Process Technology: Equipment and Systems. Recently, the industry has noticed a sharp increase in the number of women choosing process technology as an occupation. This text provides a balanced foundation for the rich diversity of students choosing to prepare for occupations in the chemical processing industry. This includes a much younger group of adult learners who will need to take the place of the baby boomer generation, as people from the latter retire in massive numbers.
As with the previous three editions, Process Technology: Equipment and Systems empowers the adult learner to accomplish the learning process. It covers the basic equipment and technology associated with the chemical processing industry.
What’s New in This Edition?
The fourth edition includes new material on distillation, reactions, and process diagrams and equipment startups. This includes vapor liquid equilibrium diagrams, McCabe-Thiele method, detailed descriptions of plate and packed columns, calcium carbonate reactions, sodium phosphate reactions, ammonia reaction, reformers, and new detail on fluid catalytic cracking. The new edition also includes start-up procedures on the following systems: heat exchangers, cooling towers, boilers, furnaces, reactors, and distillation.
New features include:
• Process Diagrams: PFDs, PFiDs, P & IDds, and Control Loops
• Distillation: vapor-liquid phase diagrams & McCabe-Thiele method
• Distillation: reflux ratio, bubble point, dew point, mole fraction
• Distillation: plate and packed column detail, column loading
• Reactions: calcium carbonate, sodium phosphate, ammonia
• Reactions: fluid catalytic cracking, reformers
• Start-up Procedures: heat exchangers, cooling tower, boilers, furnace, reactor, distillation
Key concepts and learning features include:
• Valves, piping, tanks, and vessels
• Pumps, compressors, and simple systems
• Turbines and motors
• Heat exchangers, cooling towers, and simple systems
• Steam generation, fired heaters, and systems
• Process symbols, diagrams, and instrumentation
• Utility and separation systems
• Reactor, distillation columns, and systems
• Plastics systems
Each chapter in the text moves from simple to complex topics. Learning objectives are identified at the front of each chapter. Photographs and line drawings provide a rich visual documentation on which to see the concepts and equipment discussed in the narrative. A summary and a set of openended review questions end each chapter. This text also includes a short list of equipment symbols and diagrams discussed in a specific chapter. This allows new technicians to gradually build a good understanding of basic symbols and diagrams that are part of the visual lexicon of process technology around the world.
