Knowledge Sharing for a Brighter Future
The design of the feedforward controller takes time and requires knowledge of the process and disturbance dynamics. Therefore, the decision of whether to implement or not to implement feedforward is a tradeoff. For this reason, it is interesting to have a quantitative index measuring the performance improvement that can be obtained by adding a feedforward compensator.
Read MoreAlong with wireless technology comes the flexibility and mobility in the working environment. Restrictions should be based on the application needs and/or business needs, not by technology incompatibility.
Read MoreThe primary goal of a HIPPS system is to protect against over-pressurization of a plant. It is important to know what the actual valve travel time is whenever there is an activation that is based protected volumes and speed of operations.
Read MoreA high fidelity dynamic simulator is typically used for operator training. The primary goal of which is cost mitigation by familiarizing future operators with the control scheme utilized on site and the consequences of incorrect operation so as to minimize mistakes. When properly built, these simulators can, as outlined in this article, provide benefits well beyond those of OTS.
Read MoreThe economic benefits from implementation of Visual MESA is estimated in the range of 1-5% increase of the marginal power plants. Thus, the implementation of MES technology is an important tool for solving problems of maximizing the marginal profit of thermal power plants, and optimization of the process.
Read MoreThe unit that was selected for this APC project was the Cyclohexane (CX) distillation unit because it displays the typical process characteristics in which an APC value proposition can be applied.
Read MoreIn many practical cases, PID controllers are poorly tuned because of the lack of time or operator skill, or because operating conditions change. Obviously, it is important to have relevant techniques able to automatically assess the performance of a PID controller and to retune the controller to optimize the performance. Learn more about a basic methodology that can be applied to various systems.
Read MoreIn Japanese, a special word known as “GEMBA-RYOKU” (GEMBA capability) is frequently used when discussing human resource issues in the Japanese manufacturing industry. While the word itself means “on-site capability”, this implies not only the worker’s skill, but also empowerment in the workplace ultimately contributing to improvements on the manufacturing level.
Read MoreIn our experience in deploying dashboard solutions, we find that following a specific set of implementation guidelines is very helpful in delivering effective solutions, and meeting user expectations. Learn more about visualization implementation best practices.
Read MoreIt is very critical that we try to understand operations by understanding our operators, from their point of view. Then, when implementing technologies, we focus on implementation in a manner that matches with the manner in which the operators think, and towards the goals that they need to achieve. Too often there is a focus on adding new and extra information/data.
Read MoreIn the modern connected enterprise where your industrial systems are networked to your business systems (which they almost certainly are) and your business systems are Internet facing (again very likely) then your business systems should be regarded as a potential source of threat to the integrity, safety and security of your control systems. That threat should be properly managed.
Read MoreEarly detection of CCR results in upstream units like Vacuum Distillation column HVGO samples helps Process Engineers to take corrective action upfront on the Operation of the Fluidized Catalytic Cracking unit thereby improving the reliability of the Refinery operation and improving the quality of the blended products from the Refinery.
Read MoreAs we go through our daily lives full of smart devices and cloud technologies, huge amounts of unstructured data are being gathered and analyzed to improve the way we live. Why is it that the process industry is lagging behind?
Read MoreTo perform effective analysis of downtime, a dedicated software tool that provides useful and detailed downtime and rate loss information, accompanied by manual input provides an integrated solution.
Read MoreThanks to research conducted by Shiraz University, we now have reliable statistics to understand the linkage between sleepiness and omission/commission errors, and how they increase over the course of a shift.
Read MoreIn today’s ICS landscape, many plants have yet to be assessed to ascertain the security health of their systems, processes and operations since their DCS migration to open systems architecture. Should penetration testing be included in a cyber security assessment?
Read MoreIn this article, Marcus Tennant explores alarm philosophy, alarm management and their overall purpose as they relate to the late Robert M. Pirsig's philosophy in his book 'Zen and the Art of Motorcycle Maintenance.'
Read MoreCan wireless technology be used for enhancing plant safety? The answer is YES. However, different wireless technologies may best be suited for particular types of applications, especially for safety applications. It also depends on what particular type of safety application is suitable and/or tangible for using wireless technology.
Read MorePlant operations management system greatly relieves the operations team of tedious daily activities, enabling more emphasis to be put on maximizing overall efficiency and maintain a high operating standard in terms of plant availability, reliability, utilization.
