Process Control and Optimization (PCO) is the discipline of adjusting a process to maintain or optimize a specified set of parameters without violating process constraints.
The PCO market is being driven by rising demand for energy efficient production processes, safety and security concerns, and the development of IoT systems that can reliably predict process deviations.
Fundamentally, there are three parameters that can be adjusted to affect optimal performance:
- Equipment optimization
The first step is to verify that the existing equipment is being used to its fullest advantage by examining operating data to identify equipment bottlenecks.
- Operating procedures
Operating procedures may vary widely from person-to-person or from shift-to-shift. Automation of the plant can help significantly. But automation will be of no help if the operators take control and run the plant in manual.
- Control optimization
In a typical processing plant, such as a chemical plant or oil refinery, there are hundreds or even thousands of control loops. Each control loop is responsible for controlling one part of the process, such as maintaining a temperature, level, or flow. If the control loop is not properly designed and tuned, the process runs below its optimum. The process will be more expensive to operate, and equipment will wear out prematurely. For each control loop to run optimally, identification of sensor, valve, and tuning problems is important. It has been well documented that over 35% of control loops typically have problems. The process of continuously monitoring and optimizing the entire plant is sometimes called performance supervision.
Conservation voltage reduction is the practice of operating electric distribution systems at voltages in the lower range of allowable levels, thereby improving the efficiency of many electric utilization devices (e.g. induction and synchronous motors, transformers, lighting systems, etc.).This approach can be applied to a variety of industrial settings; however, using an advanced real-time control system such as AdaptiVolt™ is critical to ensuring that voltages don’t drop to levels that put important processes at risk. AdaptiVolt™ monitors voltages through the facility in real-time and makes control decisions to safely reduce voltage, thereby achieving energy efficiency gains while maintaining process reliability
In 2012 the company, in partnership with The World Bank, launched Projeto Energia + to improve operational and fnancial performance in six Northern and Northwestern states of Brazil, as well as the management of the six distribution units. These regions, according to the National Electric Energy Agency (ANEEL) register 22% and 10% respectively of non technical losses, the highest rates in the country. In 2014 they launched the AMI (Advanced Metering Infrastructure) bid.
According to the World Health Organization (WHO), there are approximately 1.7 billion people in the world suffering from a range of mental health conditions. This might be anything from acute anxiety and clinical depression to obsessive-compulsive disorders. The WHO believes there are 23 million people suffering from these and similar conditions in Egypt alone. However, one of the factors preventing people from receiving treatments are cultural values and social stigma: they say that either these conditions do not exist, or that if people are indeed suffering, they just need the willpower to overcome their afflictions rather than seeking specialized treatment.With an estimated 10,000 website hits per month, Shezlong needed a hosting platform that could not only provide a foundation for the service but also accommodate its open source architecture.
