These days, the term electrochemistry has become almost synonymous with advanced batteries and energy-storage devices, and considerable R&D efforts abound for both batteries (Chem. Eng., October 2013, pp. 17–23) and energy storage (Chem. Eng., December 2011, pp. 19–23). Nevertheless, traditional,…
Changing markets and new applications are putting more demands on the protective coatings industry than ever before. While developing environmentally friendlier and less labor-intensive corrosion- and chemical-resistant paints and coatings is always a major goal, new formulations are needed to…
Analyze H2S content in liquids with this benchtop device Analytical Systems International Keco The Model 205L (photo) is a benchtop analyzer used to quantify hydrogen sulfide (H2S) in liquids, including crude oil, fuel oil, naphtha, water, marine diesel, gasoline and…
FIGURE 1 Fire-water pump assemblies are typically skid-mounted to ease installation and operation. Shown here is an example of a skid-mounted, diesel-engine-driven, fire-water pump package Fire-water pumps are critical machines that save lives and prevent chemical process industries (CPI)…
Using flowsheet simulation to model processes involving granular solids — either those that are entirely separate from fluid processes or those that are combined with them — has many advantages for improving the process design. These include avoiding unplanned downtime,…
Significant improvements to a process to extract vanadium, titanium and iron from the Mount Peake Vanadium-Titanium-Iron Project in the Northern Territory of Australia will be tested in a pilot plant now under construction and nearing completion. Results of the pilot-plant…
The Capitol SkyMine project in San Antonio, Tex. utilizes fluegas from an existing cement plant to manufacture salable chemicals while preventing the CO2 from reaching the atmosphere. Built by Skyonic Corp. (Austin, Tex.; www.skyonic.com), the project is said to be…
Division Radomiro Tomic of Codelco (Codelco Corporación Nacional del Cobre de Chile; Santiago; www.codelco.www) is adopting a bioleaching process to recover copper from low-grade ores. The process was developed by BioSigma S.A. — a joint venture (JV) of JX Nippon…
Process simulation methods are used to evaluate the performance of proposed distillation systems and improve the performance of existing ones. The most common approaches for modeling distillation processes can be broadly divided into equilibrium and non-equilibrium methods. This article provides…
The alcohol n-butanol is applied in the production of butyl acrylates to supply the coatings and adhesives industries. It is also used in plasticizers or directly as a solvent. It is commercially produced from propylene and synthesis gas (syngas) by…
