  • Logic Developer Process Edition Function Blocks

    Delivering increased precision and enabling advanced regulatory control strategies for continuous process control.

    Process control in the most generic sense involves continuously controlling an operation or sequence of operations that changes the state of matter; specifically, this includes changing the state of energy, chemical composition, and/or physical dimension of a substance.

    As complex programs need to interface with various aspects of a comprehensive production system, Logic Developer Process Edition function blocks from GE Intelligent Platforms add precision and ease of use to reduce the learning curve for engineers, enable higher operational efficiency, and lower development costs.

    This white paper helps engineers and programmers explore the power provided by Logic Developer Process Edition function blocks that allow changes in the state of matter to be controlled to generate beneficial outputs that enhance life (e.g., fuel in, electricity out), and illustrates how businesses can use these function blocks to realize advanced regulatory control strategies. It also explains the differences between Logic Developer Process Edition and GE's Proficy Machine Edition PLC Logic Developer programming software, which is optimal for leveraging an integrated development environment for discrete, motion, and multi-target control applications.

  • Convergence and the Programmable Automation Controller

    Ensuring your PAC-based control system is an integrated, robust and flexible information producer helps improve business performance, lower costs and uncover unique opportunities for competitiveness.

    All companies seek ways to make their businesses grow for the long-term. Ask any manufacturer today what he/she needs in an increasingly challenging economy. It's likely to include cutting costs, improving yield, increasing functionality and becoming more competitive in the global marketplace.

    Manufacturing convergence helps companies meet these business drivers - globalization, innovation, productivity and sustainability - by more closely aligning manufacturing technologies and production system operations with the rest of the enterprise. This convergence is enabled throughout the manufacturing environment with the technologies of convergence - control, power, information and communication.

  • Setting a New Standard in Alarm Management

    Alarm management affects the bottom line. A well-functioning alarm system can help a process run closer to its ideal operating point - leading to higher yields, reduced production costs, increased throughput and higher quality, all of which add up to higher profits. Poor alarm management, on the other hand, is one of the leading causes of unplanned downtime and has been a major contributor to some of the worst industrial accidents on record. Changing the practices and procedures used in the plant has become easier and more important with the release of a new ISA standard on alarm management. The ISA-18.2 standard, which provides a blueprint for creating a safer and more productive plant, is expected to be adopted by OSHA and insurance agencies as "good engineering practice." Download this white paper to see an overview of the new standard, examples of how to follow it and more.

  • Finding the Root Cause of Process Upsets

    Today's process plant is a complicated place. Multiple raw materials combine with multiple energy streams to produce primary and secondary products. Process variability comes from the raw materials, operating practices, weather, process upsets, maintenance issues and hundreds of other sources. Finding the root cause of a process upset is critically important to permanently solving process upsets. Trying to tune all the affected control loops is simply chasing after symptoms, rather than getting to the heart of the issue.

  • Introduction to Vibration

    Vibration is a characteristic of virtually all industrial machines. When vibration increases beyond normal levels, it may indicate only normal wear, it may signal the need for further assessment of the underlying causes, or for immediate maintenance action. But how can the plant maintenance professional tell the difference between acceptable, normal vibration and the kind of vibration that requires immediate attention to service or replace troubled equipment? Download this white paper and learn how to tell this difference.

  • Plant Modeling: A First Step to Early Verification of Control Systems

    Today's control system engineers face competing design demands: increase embedded system performance and functionality, without sacrificing quality or breaking the budget. It is difficult to meet these challenges using traditional design and verification approaches.

    Without simulation it is impossible to verify a control design until late in the development process when hardware prototypes become available. This is not an insurmountable problem for simpler designs with predictable system behavior, because there are fewer sources of error in simpler control algorithms--and those errors can often be resolved by tuning the controller on the hardware prototype.

    Today's multidomain designs combine mechanical, electrical, hydraulic, control, and embedded software components. For these systems, it is no longer practical to delay verification until late in the development process. As system complexity grows, the potential for errors and suboptimal designs increase. These problems are easiest to address when they are identified early in the development process. When design problems are discovered late, they are often expensive to correct and require time-consuming hardware fixes. In some cases the hardware simply cannot be changed late in the development process, resulting in a product that fails to meet its original specifications.

    Traditional verification methods are also inadequate for testing all corner cases in a design. For some control applications, it is impractical or unsafe to test the full operating envelope of the system on hardware.

  • Development of Integrated Flexi-Burn Dual Oxidant CFB Power Plant

    Carbon-dioxide capture and storage (CCS) offers the potential for major reductions in carbon dioxide emissions of fossil fuel-based power generation in the fairly short term, and oxyfuel combustion is one of the identified CCS technology options. Foster Wheeler (FW) is working on reduction of carbon dioxide with its integrated Flexi-Burn dual-oxidant PC and CFB technology.

    The proven high efficiency circulating fluidized-bed (CFB) technology offers a solution for carbon dioxide reduction both in re-powering and in greenfield power plants. CFB technology has the advantages of a more uniform furnace heat flux, excellent fuel flexibility and offers the opportunity to further reduce carbon dioxide emissions by co-firing coal with bio-fuels.

    Development and design of an integrated Flexi-Burn dual-oxidant CFB boiler and balance of plant system was conducted in both air mode and oxyfuel mode. Through proper configuration and design, the same boiler can be switched from air mode to oxyfuel mode. The dual-oxidant CFB system incorporates features to maximize plant efficiency and power output when operating in the oxy-firing mode through firing more fuel in the same boiler.

    Existing boiler design tools are being modified to incorporate the features of oxy-combustion, so that various design options can be evaluated. The 460 MWe supercritical CFB power plant (currently under construction by FW) has been used as the basis for an integrated Flexi-Burn dual-oxidant CFB study.

  • Process Analytics Finds Process Problems

    Process Analytics and Intelligence—sometimes called Manufacturing Intelligence—has transformed the way companies produce goods, understand their manufacturing processes, and ensure a quality product in ways we could not have foreseen ten years ago.

    Real-time Analytics have replaced the legacy concept of running reports. Reports that represent a static picture of a process at a fixed point in time are great tools for compliance audits and long term warranty analysis. However, they may not accurately represent the "as-is" state of a process. Reports showing large amounts of data can be difficult to interpret. There are often limitations in how the report data can be drilleddown and viewed.

    With today's large volumes of data, there's a wealth of information that can be gained about the process. But how can this data be captured, managed and retrieved in a way that presents the information in an up-to-theminute easy to understand format? Real-time Analytics provides the techniques and solutions that address this problem. Instead of users having to interpret the data, it's presented in a graphical form enabling them to easily drill down to explore the data in real-time.

    This white paper discusses how Process Analytics is implemented and utilized. Ways of managing and distributing Process Analytics to the organization are presented.

  • The Eye for Plant Operator's Eyes

    The plant operator has an extremely valuable and important responsibility: being the force and energy managing a capital enterprise easily worth hundreds of millions of dollars to produce or impact a daily revenue stream of millions, give or take. We ask him to be ever mindful of what the plant might be doing. We ask him to be capable of finding every little problem before it grows into a big one. We ask him to shoulder the burden of everything that goes wrong during his watch, all without any recognition when nothing does, and precious little (if not actual blame) when it goes wrong and he manages to manage. Within his area of responsibility and authority he must be able to view every control loop, most sensors, most pieces of equipment, and much of the supporting utilities, and then adjust as appropriate.

    The failure to maintain situational awareness has been present in almost every disaster event that was not the result of spontaneous complete surprise. Start with the assumption that no one wants an accident. That no one would chose disaster over success. But accidents and disasters happen. We now know to a high degree of certainty that they happen because those in charge of ensuring that they do not happen, aren't aware that they are happening. They fail to know the situation. They are unaware of what is really going on, what is likely to happen, or what isn't happening that they think is. As explained in my book Alarm Management for Process Control, the solution is facilitated by effective operator interface design. Let's follow the path of interface design that can lead to better situation awareness.
