Preface This book is based on 50 years of experience gained whilst working in the process engineering and simulation fields. It is not suitable for rigorous academic study, as it is intended for the practicing engineer. However, certain cases could provide a more practical basis for student process design projects. There is nothing original here, as the information has been developed from experience and has been collated from individual technical papers and guidance notes developed in support of our engineering and simulation activities. Reference has been made to many classic texts in Chemical Engineering literature, including the following:

➢ Kern, Process Heat transfer, McGraw Hill ➢ Treybal, Mass Transfer Operations, McGraw Hill ➢ Norman, Absorption Distillation and Cooling Towers, Wiley ➢ Olson, Fundamentals of Engineering Fluid Mechanics, Intertext ➢ Fielder & Rousseau, Elementary Principles of Chemical Processes, Wiley ➢ Smallwood, Solvent Recovery Handbook, Edward Arnold ➢ Kohl & Nielsen, Gas Purification, Gulf ➢ Newbury, A Concise Organic Chemistry, Harrap ➢ Warn, Concise Chemical Thermodynamics, Van Norstrand Reinhold ➢ Shinskey, Process Control Systems, McGraw Hill ➢ Spink, Flow Meter Engineering, Foxboro ➢ Flow of Fluids 410, Crane ➢ Control Valve Handbook, Fisher Control Company ➢ Reid, Prausnitz & Poling, Properties of Gases and Liquids, McGraw Hill ➢ Watson, Thermal Design of Shell and Tube Heat Exchangers

Each section is in the form of a condensed refresher providing useful practical information gleaned from many sources. Applications are presented from projects involving design, simulation and operations. Units used are not consistent as selection depended on the preferred units for a particular study. Sections are numbered uniquely for contents and references, with specific appendices and nomenclature. The references are not a comprehensive list and apologies for any unintended omissions. Any originality may be in the presentation format and as such some would consider this to be a Handbook or Workbook. Many modern books in Chemical Engineering do not adopt this approach which is not very helpful to the engineer challenged with providing a solution in a timely manner.

2nd Edition Sections have been reorganised and rationalised, including Process Instrumentation and Control, Fluid Flow and Piping Networks, Emergency Relief Systems and Batch Distillation. A new Utility System Section has been added and includes cases on CHP Steam Systems, Refrigeration and Cooling Towers. Several new cases have been added to demonstrate dynamic simulation capability; in particular Fire Induced H2O2 Thermal Decomposition and Bio-fuel Blending. Additional diagrams and engineering data have been added where appropriate.

3rd Edition Section order has been changed to give a more logical presentation and section index added. Fundamentals section has been extended to provide a more comprehensive study of separation processes using equilibrium flash and to demonstrate the power of flash simulations. Heat Exchanger Design and Rating has more detailed information on design with more real cases. Process Instrumentation and Control has been rewritten to incorporate TechTalk papers published by the author in The Journal of the Institute of Measurement and Control. Dynamic Simulation section is introduced and applied to the study of common process operations. Refinery Processes includes a more comprehensive review of refinery operations. General information has been extended to include a summary of heuristics for process equipment

CHEMCAD Software Licence Process simulation examples are carried out using CHEMCAD™ simulation software by Chemstations, Inc. of Houston www.chemstations.com . The simulation cases are available in electronic format. To run the simulations you will need a CHEMCAD software licence.

Introduction

The process industry covers a broad spectrum of activities that involve the handling and treatment of gases, liquids and solids over a wide range of physical and processing conditions. The scope of this variety is shown in the following chart. The development of a process and the steps taken to achieve an operational full scale unit are complex and involve many disciplines to achieve a successful result. Typical activities are shown in the following chart.

The process engineer, working in this environment, is required to provide safe, practical and timely solutions to design problems without having the opportunity to study the topic in great depth. This book is an attempt to provide a comprehensive review of the fundamentals, definitions and design principles to allow the solution of cases encountered in normal practice. For more complex cases or when in doubt reference should be made to an appropriate authority or specialist in the field. The design process should attempt to identify potential problems and errors at the earliest stage possible in the project life cycle. Many techniques have been developed to achieve this, namely Hazard Identification (HAZID), Hazard and Operability (HAZOP), Layer of Protection Analysis (LOPA) together with process simulation. The project cost impact curves show the benefits of stress testing the designs using these techniques to avoid the increased costs of correction, even if economically possible, later in the project life cycle.

Processes can be batch, semi-continuous or continuous and the selection depends on many factors.

Batch processes are used in the manufacture of a wide variety of fine and speciality chemicals and involve the following general criteria:

• Low to medium capital investment

• Low to medium cost to rectify design errors

• Low volume high value products

• Low to medium production costs

• Limited savings from yield improvements and reduced cycle times

• Multi-purpose capability often required

Batch processes are inherently transient in nature and the equipment design needs to be analysed using the physical properties of the process and service fluids under a wide range of operating conditions. Continuous processes are used in the oil and gas processing and petrochemicals industries and have the following characteristics:

• Heavy capital investment

• Expensive to rectify design errors

• High volume low to medium value products

• Well established process or high level of confidence in design for new process

• Large savings in raw materials and energy achievable with process optimisation

• Product change capability required in some processing units

To achieve consistent quality and to operate the process optimally maximising productivity and minimising raw material and energy costs requires effective control of the key process parameters. This requires process control and data monitoring systems that match the process to which they are being applied.

A successful outcome does not necessarily require an in depth mathematical study of the control system and its interaction with the process, which is how courses on instrumentation and control are frequently presented. Very often having a good understanding for the process behaviour and the application of common sense can provide satisfactory results. In 1967 Shinskey presented a novel approach to the understanding of process characteristics and the associated control systems by studying the problem in the time domain and the application of basic mass and energy balances. Each process parameter exhibits unique properties that determines the control strategy to be applied.

• Flow and liquid pressure periods are fast and noisy with no dead time, requiring a low gain response with reset adjustment to maintain a desired value.

• Gas pressure exhibits a high capacity with no dead time, requiring a high gain response which is adequate to maintain a desired value. This is considered to be the easiest parameter to control.

• Liquid level period can be fast or slow and sometimes noisy (boiling) with capacity, requiring medium gain and sometimes with reset adjustment to maintain a desired value.

• Temperature period can be medium or slow with capacity and dead time, requiring variable gain, reset adjustment and anticipatory response.

The control system should not be used to overcome shortcomings in plant design. To avoid this the process plant design and the control philosophy should be considered throughout the design process. For example, if a processing unit takes a long time to achieve stable and optimal operating conditions the feeds should be held constant by the use of surge tanks in which the level is allowed to float between acceptable limits. Steady state and dynamic process simulation proves the capability to achieve stable and reproducible operating conditions with acceptable product purity, yield and cycle times to satisfy the commercial requirements and the safety and environmental issues for the regulatory authorities. The characteristic properties and design parameters of the process are analysed in this book using the CHEMCAD™ range of software. It is worth noting that many serious accidents on process plant have been as a result of failures in plant management systems and procedures and not due to failures in design. However the design and commissioning teams have the responsibility to ensure that adequate documentation and procedures are handed over to operations personnel, which should include a clear understanding of accident risks and the safety critical equipment and systems designed to control them. Maintaining a corporate memory is a serious challenge to all managements which can only be achieved by adequate systems, auditing procedures and continual training.
