ADVANCES IN PROCESS GAS ANALYZERS
By Chemical Engineering
Between process-control optimization initiatives and increased environmental monitoring requirements, the number of gas analyzers in chemical-process-industries (CPI) facilities is proliferating at a faster rate than plant analyzer budgets and manpower can accommodate, according to industry experts. At the same time, a lot of employees with analytical expertise are retiring, so the analyzer knowledge base is shrinking dramatically.…» |

ADVANCING WITH AUTOMATION
By Chemical Engineering
Many, if not most, of us have heard of the Industrial Internet of Things (IIoT). Simply stated, it refers to the manufacturing application of the Internet of Things, or the interconnectedness of “smart” machines. Similar to what we see with the rapid advances to our personal devices, such as smart phones, smart cars, smart televisions and more, smart devices in industrial settings offer the ability to move to new manufacturing strategies.…»

CYBERSECURITY: PROTECTING YOUR INDUSTRIAL CONTROL SYSTEM
By Chemical Engineering
In December 2015, 80,000 homes in the Ukraine were left without power when a cyber attack took down the electrical infrastructure. Investigations suggest that hackers used malware in conjunction with remote access to industrial control systems to directly interact with control systems, infect workstations and servers with malware, damage control-system hosts on workstations and servers, and block calls to customer call centers that would have alerted power companies to the outages…» |

LEVEL-MEASUREMENT DEVICE SELECTION
By Chemical Engineering
Effective level measurement in the chemical process industries (CPI) helps maintain material inventory at economic quantities, improves product quality and maximizes plant output by avoiding spills and process upsets. When they are incorrectly matched to their application, level-measurement devices can contribute to lower quality and poorer process consistency. No single level-measurement technology is suitable for all applications. This column provides information about level measurement technologies and guidance for choosing the most accurate and effective device for an application. Technology approaches The technology used by level measurement devices can broadly be divided in multiple ways. One method is to think about them as point-level versus continuous-monitoring devices, and another way is to classify them as either contact or non-contact devices. Point versus continuous. Point-level detection is mainly conducted by liquid-level switches. These switches or liquid-level gages are designed for controlling the…»

INLINE VISCOSITY MEASUREMENTS
By Chemical Engineering
Inline viscosity measurements can give continuous, realtime readings of a fluid’s viscosity during processing and consequently, can provide a means to automate the viscosity control of process fluids. While it is difficult to control all factors in the process that can affect a fluid’s viscosity (such as temperature, air bubbles, shear history, turbulence and so on), if these factors are kept relatively constant, then good control can be achieved. This article presents the applications for inline viscosity measurement and the means by which they are achieved. Let’s first discuss the subject of viscosity. The basics Viscosity is a property that is often considered by process engineers, but seldom completely understood. It is generally not a subject that is covered in much detail in many engineering curricula. Most engineers know what viscosity is, but may have trouble explaining it or…» |

| Key Reactions for the Petrochemical Industry |
| A handful of compounds derived from natural gas and crude petroleum are converted into a vast array of industrial petrochemicals. Starting materials for most petrochemical intermediates include synthesis gas, ethylene, propylene, butadiene and BTX (benzene, toluene, xylenes). This one-page reference provides an overview of the chemical routes and reactions required to manufacture these fundamental petrochemicals, as well as reactions for generating some of their immediate chemical derivatives…» |
