Several regulations exist to document the proper use of personal protective equipment and safety precautions but it is ultimately up to the worker to prevent accidents.
  • Troubleshooting
    • Troubleshooting is a method for finding the root cause of a problem and correcting it. The ultimate goal of troubleshooting is to get the equipment back into operation. An entire production operation may depend on the troubleshooter’s ability to solve a problem quickly and economically. At times, such a task might present itself as a daunting process. Fortunately, technicians have, through trial and error, adopted a series of best practices that, if followed, will make the task of troubleshooting any equipment or process much more intuitive. Sticking to these best practices and adopting a logical approach to solving the problem is always the best way to resolve the situation at hand. 

Introduction to Instrumentation and Control

  • Industrial Instrumentation and Control Overview
    • Instrumentation and control technicians maintain the safe and efficient operation of industrial measurement and control systems. A broad knowledge of multiple disciplines is required to effectively work with and troubleshoot instrumentation systems; physics, chemistry, mathematics, electronics, mechanics, and control theory all need to be applied to some extent. An instrument technician must be able to synthesize and apply this knowledge to real applications. The continued addition of new technologies adds to the challenge. For existing industrial facilities, new equipment is phased in for specific applications and legacy technologies typically remain. It is very common to find state-of-the-art instrumentation next to decades-old instruments, such as digital networks running alongside pneumatic signal tubes or microprocessor-based sensors mounted next to mercury switches. A competent instrumentation and control technician must be comfortable working with old and new technologies, and also have a sound knowledge of measurement principles and system interactions.
  • Principles of Measurement
    • The fields of measurement and instrumentation involve very specific terminology for describing instrument performance characteristics. A technician routinely encounters these terms and principles on the job, typically in the form of instrument specifications. Additionally, many of the routine tasks performed are related to instrument calibration, and are based on basic measurement principles to ensure instrument performance is in conformance to specifications.
  • Industrial Signal Standards
    • A technician may encounter a wide variety of signal standards based on the type of industrial processes and, depending on the age of the facility, possibly multiple generations of standards. A background in common analog and digital standards provides a technician with perspective, necessary for understanding the specific standards used in a specific facility, as well as the reasons for their use.

Process Measurement

  • Pressure Measurement
    • Pressure is one of the fundamental parameters measured in industry. A typical industrial facility may have hundreds or even thousands of pressure meters.
  • Level Measurement
    • Liquid level measurement is critical to the safe operation of a facility. The level measurements obtained are used to monitor and control many of the processes in an industrial facility. Numerous technologies exist that measure the liquid level in a vessel; each type uses different principles of physics to sense the level and provide output to a transmitter or transducer. The basic types of measurement devices can be broken up into two categories, direct measurement and inferred measurement.
  • Introduction to Flow Measurement
    • Flow measurement is one of the four fundamental parameters measured in industrial instrumentation that every technician needs to be well versed in, particularly the principles and technology used. It is also arguably the most complex and has the greatest variety of types of measurement devices.
  • Head Flow Meters
    • Head flow meters, or differential pressure flow meters, are the most common flow meters used in industrial facilities. It is estimated that over 50 percent of all fluid flow measurement applications use head flow meters.
  • Linear and Mass Flow
    • Linear meters, as the name implies, are a classification of flow meters that do not require square root extraction. The two main categories of linear flow meters are: Positive displacement flow meters that directly measure volumetric flow. Velocity flow meters that inferentially measure volumetric flow. Both head and linear flow meters can be used to derive mass flow rate. However, true mass flow meters are used to more accurately measure mass flow rate.
  • Temperature Measurement I
    • Temperature measurement is critical to controlling equipment, processes, and other industrial applications. From power plants to warehousing facilities, accurate temperature measurement is critical to the safe operation and control of these processes and facilities. There are many ways to measure temperature, from the familiar liquid filled thermometer to using resistance temperature detectors and thermocouples. This module will cover the most common methods used to measure temperature.
  • Temperature Measurement II
    • There are many way to measure temperature. From the simple liquid-filled thermometer to the infrared pyrometer, there are a number of reliable and accurate devices used in industry to perform this critical measurement. The type of device chosen is usually determined by factoring in required accuracy, the environment in which it is used, the temperature range over which the measurement is required, and the cost.

Process Control and Monitoring

  • Process Control Fundamentals
    • In almost all industrial process applications, control of process variables is critical to the safe and efficient operation of the process. The most common variables controlled are pressure, level, temperature, and flow. Even though there are many different methods used to control these processes, this monitoring and control is generically called process control. Level, pressure, temperature, and flow are all controlled in a similar fashion. In this series of modules, level control will be used to explain the various concepts and control methods.
  • Two-Position and Proportional Control
    • Control of processes is accomplished by using a number of control strategies. Two of the most common methods of control that will be discussed in this module are two-position and proportional control.
  • Integral, Derivative, and PID Control
    • Offset error in proportional controllers is a problem when trying to maintain a process variable at an exact value. As we saw in the proportional control module, one way to eliminate offset error is to manually reset the controller. The problem with manual reset is just that — it’s manual. If we could automatically perform a reset every time a process supply or demand change occurred, the issue of offset error would be eliminated. We can do just that by adding integral to a controller. Integral, sometimes called reset, is used in conjunction with proportional control to bring the process back to setpoint without having an offset error. While integral eliminates the offset error, it brings its own issues, which are dealt with by adding derivative to the mix. The result is a control mode known as proportional, integral, and derivative control, commonly known as PID control.
  • Loop Tuning
    • In order for a control loop to operate as desired, it must first be tuned. Tuning a control loop is the act of adjusting the values of proportional gain, integral gain, and derivative gain such that the process responds in a manner desired by the operator. There are two major methods of tuning a control loop: open and closed loop. Almost all technicians will use the closed loop method, where data is taken from an operating loop that is online. Open loop methods are more often used on the initial startup of a system and allow engineers to collect baseline data. This module will only cover closed loop tuning methods.
  • Advanced Control Methods
    • While PI or PID controls are the most common forms of control strategies used on control loops, there are some other control strategies that are used to solve control issues. The control strategies discussed in this module are: Feed forward control Cascade control Ratio control Three element control
  • Introduction to Actuators
    • A single facility can have hundreds, if not thousands, of valves to control everything from turbine operation to ventilation, to systems that ensure the safety of personnel and equipment. The valves used can range in size from less than an inch to several feet in diameter. While some of these valves are designed to be operated manually, many of them require some form of automatic or remote operation. Operators and technicians must understand the different types of actuators used to operate these valves, and how these actuators work.
  • Actuator Principles of Operation
    • A single facility can have hundreds, if not thousands, of valves to control everything from turbine operation to ventilation, to systems that ensure the safety of personnel and equipment. The valves used can range in size from less than an inch to several feet in diameter. While some of these valves are designed to be operated manually, many of them require some form of automatic or remote operation. Operators and technicians must understand the different types of actuators used to operate these valves, and how these actuators work.
  • Control Valve I
    • On June 11, 2008 at the Goodyear plant in Houston, TX, a heat exchanger violently ruptured due to an over pressurization caused by the isolation of a pressure relief valve. An employee walking nearby was killed by the hurtling debris from the explosion. An understanding of the importance of these valves and their proper positioning could have prevented this incident. In this module, several types of these valves and their common components will be briefly discussed, as well as the proper mounting and installation guidelines.
  • Control Valves II
    • Isolation or insufficient flow can result in instantaneous overpressurization and/or explosions; therefore, the proper positioning of isolation and throttle valves is crucial to the safe operation of any system. Gate, globe, needle, and butterfly valves are all used to stop, start, and throttle flow.
  • Control Valves III
    • Flow reversals and improper flow rates can lead to equipment failure and destruction. By understanding valve operations and ensuring proper valve orientation, these situations can be avoided. Ball valves and plug valves are used to stop, start, and throttle flow, while the check valve is used to prevent flow reversal, and the regulating valve is used to automatically adjust flow.
  • Control System Architecture
    • Control loops, implemented with proportional, integral, or derivative control circuitry and simpler on/off system control points, are utilized within one of three architectures. PLCs, or Programmable Logic Controllers, are used in smaller and simpler applications. They are the oldest of the three technologies and are often programmed with ladder-logic, relay-based tools. DCSs, or Distributed Control Systems, can be used to control an entire, large scale production facility, such as a power plant or refinery. DCSs can control separate PLC systems and have other branches they simultaneously control. SCADA, or Supervisory Control and Data Acquisition, systems are used to control even larger applications, such as a series of power plants connected to a grid or multiple refineries all supplying multiple pipelines.

Procedure Writing Best Practices

  • Procedure Writing Best Practices
    • Procedure writing is both an art and a science. Well written procedures reduce the number of errors and omissions in operations and maintenance, as well as assist less experienced personnel to perform complex tasks efficiently and effectively.

Workflow and Controls

  • Workflow and Controls
    • An important part of maintenance is a structured control program. This program provides a means to provide instructions for the maintenance technician through work orders. Work order results are recorded to provide a history of performance both of the technician and of the equipment. Performance of maintenance is scheduled for equipment access, cost control and to maximize equipment uptime. Planning the performance of jobs allows pre-staging of parts, tools and even pre-briefing of technicians on performance of work to increase efficiency. Tracking of performance through a series of key performance indicators will allow continuous improvement of the maintenance organization. 

Preventive Maintenance Programs

  • Preventive Maintenance Programs
    • Periodic maintenance, performed to extend the life of equipment and reduce operating costs, is known as preventive maintenance. When you change the oil in your car, it is preventing premature failure of the engine. Your mechanic may tell you to change it every 3000 miles. Where does this number come from?

Introduction to Maintenance

  • Introduction to Maintenance
    • Whether a ship at sea, a car in your driveway or an 800 MW electrical generator at a power plant, all equipment is subjected to wear. Sometimes the wear is in the form of corrosion from exposure to chemicals or harsh atmospheric conditions. Sometimes it is due to friction or heat. Continued wear eventually results in failure of the equipment. Equipment is designed to perform a specific function over a defined time period. Excessive wear reduces the lifespan causing early failures. Whatever the cause, it is the inspection, repair, and replacement of components, known as maintenance that keeps the equipment running. 

Condition Based Maintenance

  • Condition-Based Maintenance
    • Condition-based Maintenance, or CBM, is the process of measuring and analyzing a parameter that has a direct relationship to the health, or operational, condition of equipment. The goal of CBM is to identify and correct equipment degradation prior to failure. CBM is also known as condition monitoring, or performance monitoring, or Predictive Maintenance, which is abbreviated as PdM. There are a wide range of predictive technologies that support CBM.
