Piping integrity is always a major concern in the chemical process industries (CPI), but the level of concern elevates when piping is buried underground. Soil conditions not only exacerbate general external corrosion, but also increase the difficulty and cost of inspection — a necessary step for ensuring safe and reliable operation. Making matters worse, many underground piping systems are...

Buried piping — especially lines carrying hydrocarbons — shoulders many more risks in terms of plant safety and environmental protection than aboveground piping does. Leaks in buried pipes are much harder to detect and, yet, are no less catastrophic. Ironically, underground piping design does not get as much emphasis in the chemical process industries (CPI) as aboveground piping does. Whether...

Throughout the chemical process industries (CPI), project owners often track key performance indicators (KPIs) to ensure that all participants are able to attain or improve important performance objectives associated with their investments. For instance, for complex projects involving various contractors and sub-contractors, the predetermined expectations spelled out in the agreed-upon set of KPIs allow...

A biological process for the destruction of sodium oxalate at Alcoa’s Kwinana alumina refinery in Western Australia has proven to be an extremely robust technology. Alcoa’s residue technical manager, David Cooling, says the plant has achieved an oxalate destruction rate of 40 metric tons per day (m.t./d), and the company plans to increase the destruction rate to 60 m.t./d. The technology has...

Phosphorous impurities in steel can lead to detrimental properties, such as reduced hardness and resistance to corrosion. Sumitomo Metal Industries, Ltd. (SMI; Tokyo and Osaka, Japan; www.sumitomometals.co.jp) has enhanced its SRP (simple refining process) for removing phosphorous from pig iron — a step necessary for making high-grade steels. The so-called SRP-Z process (diagram) involves blowing a...

Two waste products — carbon dioxide and industrial wastes — are combined to obtain marketable mineral products in a process being developed by startup company CarbonX Inc. (Santa Barbara, Calif.; www.carbonxinc.com). The process produces precipitated calcium carbonate (PCC) and silica from such wastes as steel industry slag and flyash from lignite-fired power plants, cement kilns and municipal...

A new system for detecting chemical or biological contaminants in water is made possible by analyzing the swimming pathways of one-celled protozoa that are introduced into the water sample. Alterations of the protozoa’s swimming mechanics, relative to a clean water control, indicate the presence of toxins. The Swimming...

  Betaine production A new process that produces natural betaine is being scaled up by Novasep Process (Pompey, France; www.novsasep.com) and Danisco (Copenhagen, Denmark; www.danisco.com). The plant will be the first to exploit a new extraction process that uses vinasse — a byproduct of sugar-beet-derived bioethanol. The process incorporates Daniscos proprietary NS2P chromatography technology...

In recent years, a number of factors have further emphasized the importance of solvent selection in the chemical process industries (CPI). These include the increasing regulatory scrutiny leveled on industrial solvents, and an effort by CPI companies to reduce the environmental, health and safety (EHS) impact of their solvent use. In addition, specialized, high-performance solvents are available for some...

Some columns sway with the wind; some columns sway with the waves. In fact, hundreds of columns now reside offshore, on platforms and on barges. Most dry and sweeten gases. Some distill. The trays and packing distributors of such columns are regularly, appreciably out of level. Sloshing occurs. The packings are regularly, appreciably off vertical. Some of what we know about the design of such columns...

Questions of CE history I was digging through some old files in my office and came across a February 5, 1962 publication of Chemical Engineering. It’s in good condition and I have now framed it and placed it on my wall in my office. Kinda neat. I was curious to know when was Chemical Engineering’s first publication and which number the one I have might be. — David Naydyhor ICL Performance...
