The chemical and petrochemical industries produce a wide variety of products that are essential for modern industrialized societies. Chemicals are the building blocks for products that meet fundamental needs for food, health, and consumer products. Chemicals are also essential to wide range of industries such as pharmaceuticals, automobiles, textiles, furniture, paint, paper, electronics, agric...

Valves are ubiquitous as final control elements in the chemical process industries. Motivated by heavy valve usage by the process industries and many industrial reports of valve nonlinearities undermining effective process control, this article summarizes our recent work that unifies concepts related to valve dynamics with frequently reported industrial concerns, and also investigates methods o...

— Seven important variables having profound impact on the ability of a mixing tank to suspend particles have been investigated using computational fluid dynamics (CFD) technology. The results obtained from this study can be applied across a broad range of industries such as the chemical, biochemical, petrochemical and mineral processing industries. Finally, a design template incorporating the o...

Measuring substrate and/or product concentration can create a major bottleneck for synthetic and biosynthetic processes. Here we report the development and substrate screening of a whole cell biosensor to detect biomass-derived aromatic chemical building blocks, supporting the use of sustainable feedstocks in the bulk and fine chemical industries.

Inspectors first discovered chemical mixtures leaking from a Freedom Industries storage tank into the Elk River on 9 January 2014. The Elk River provides drinking water for some 300,000 Charleston-area residents, who for several days relied on water that was trucked in by the National Guard and other groups. The disruption cost local businesses more than $61 million, according to preliminary es...

Flash chemistry based on high-resolution reaction time control using flow microreactors enables chemical reactions that cannot be done in batch and serves as a powerful tool for laboratory synthesis of organic compounds and for production in chemical and pharmaceutical industries.

Multiphase reactors have been at the cutting edge of technology development in the chemical industry. This premier status of multiphase reactors can be best appreciated in the context of the evolution of the chemical industry itself. It is therefore appropriate to discuss specific aspects relating to the growth and progress of the chemical process industries. This introduction starts with the e...

dumbells, barbells, and other early resistance apparati in unexpected Halteres varied greatly in appearance and composition during the era modern historians refer to as Ancient Greece. Accordplaces. In some instances, the printed references were surprising because of the early date at which they were published. In other ing to John Blundell’s The Muscles and Their Story, published in 1864, the ...
