Security of SCADA (supervisory control and data acquisition) and other industrial control systems (ICSs) is a complex subject, and one that has received much attention in recent years. While modern industrial control systems use many of the same computers, operating systems and networking components as conventional business networks, the two kinds of networks are managed very differently. As a result, what...

Rotary valves are used almost universally in pneumatic conveying systems. They serve three main functions: 1) to provide a pressure-seal (airlock) between two adjacent processes, 2) to provide solids metering (feeding) and 3) to provide a combination of solids metering and a pressure-seal for feeding solids into a pneumatic conveying system. Rotary valves are common devices for feeding solids into a...

For most engineering-procurement-construction (EPC) projects in the chemical process industries (CPI), the data sheets developed at the beginning of the process provide the “shopping lists” that guide the procurement group on the purchase of equipment, system packages, instruments and more. Data sheets should function as the central document, into which all final result of design or...

There is an emerging crisis brewing for the chemical processing industries (CPI) in many regions of the world. Those regions include China, the world’s manufacturing powerhouse; swaths of the U.S., including large parts of its South; and chunks of Europe. For once, the crisis has nothing to do with energy costs. The emergence of cheap shale gas in the U.S., and the identification of exploitable...

Dry, granular solids can be conveyed in a number of ways. Two common devices for transporting granular solids are the angular-pitch vibrating conveyor and the horizontal differential-motion conveyor. The variability in the design and performance between the two types stems from the differences in the kind of motion required to move the mass in one direction. The most significant difference between the two...

Calculating the volume of a liquid in a vessel of a complex shape is a common task for chemical engineers. However, there are several difficulties associated with accurately carrying out this calculation. In my own experience as a chemical engineer, I have become familiar with the complexities of calculations related to determining the volume of a liquid contained in a vessel with an irregular shape...

Ethylene is arguably the most important building block of the petrochemical industry, frequently produced via steam cracking of a range of petroleum-based feedstocks. Rising oil prices and concerns about global warming have motivated research into ethylene manufacture from renewable sources. The “green” ethylene made from ethanol (for example, from corn, sugarcane or lignocellulosic biomass)...

Ongoing advances in the design and use of dry gas seals (DGSs; [ 1]) — as an alternative to traditional oil-lubricated wet seals [ 2] — have helped to improve the reliability and efficiency of compressors throughout the chemical process industries (CPI). One of the major design considerations in mechanical seals is how to protect seal faces from wear, as one face rotates close to a static face...

Chemical technology is in a state of constant innovation and evolution that is being spearheaded by laboratory researchers across the world. Within the past decade, research specific to “green” or bio-based chemicals has gathered funding and momentum as broad-based opinion has shifted toward themes such as sustainability, renewables and conservation. This momentum has impelled advances in green...

During process operations, elevated pressure inside of isolated zones within a process or system can be rapidly reduced by the release of gas and vapor to a dedicated blowdown network. Analysis can be carried out to determine whether a given pressure-relief device will provide sufficient protection from potential vessel rupture for an unwetted-wall vessel or a vessel containing a high-boiling-point liquid...

Increasing production of crude oil from shale deposits in the U.S. and oil sands in Canada offers North American petroleum refiners opportunities to access cost-advantaged feedstock. However, shifting product demand and hurdles in transportation logistics, along with technical issues associated with the properties of the crude from those areas, present challenges as refiners optimize their product mix...

Lessons learned Your Editor’s Page in today’s Chemical Engineering [March 2013, p.5] intrigued me because I too served as a TA in a physical chemistry lab but long before 1980 and we did not have the luxury of a Fourier-transform infrared spectrometer. But you certainly have the experience to comment on the following: The earth, according to Weil’s law at an average temperature of...

Minimizing process variability is an important component of a plant’s profitability. The performance of control valves within process control loops has a significant impact on maintaining consistent processes. This refresher outlines some of the important aspects of control-valve performance, including parameters of both the static response and the dynamic response. Static response A valve’s...
