Despite the immense value and universal appeal of these additives for product designers, process engineers facing the day-to-day reality of full-scale production face a unique set of challenges. Dispersing these powdered additives into a liquid is one of the most formidable challenges in the chemical process industries (CPI). Although most can be dispersed fairly easily in a common laboratory mixer, when...

At last month’s CosmoProf exhibition (April 10 – 14; Bologna, Italy), VMI-Rayneri (Montaigu, France; introduced a new vacuum-injection process for dispersing powder-like solids into liquids or pastes during the production of cosmetics, pharmaceuticals, food or other chemical products. Normally, homogeneous dispersions are prepared by either circulation within the...

Less "Balling" of Dry Powder with This Mixer Outfitted with three independent agitators, the Triple Action Disperser promises a low energy and fast method for mixing high-quality dry powders into liquid dispersions. Its design allows for a controllable vortex and powder wetting, preventing the "balling" typical of powders on liquid surfaces. The disperser is available in 350 to 20,000 L...

At Pollutec 2007 (Paris, France; November 27 – 30), Veolia Water Solutions & Technologies (Paris, introduced the next generation of its Actiflo clarifier process for potable and process water — Actiflo Turbo. Like its predecessor, the patented Actiflo Turbo process uses microsand to enhance flocculation and settling, which makes the process quicker to startup, more...

At the Chem Show last month (New York; Oct. 30 – Nov. 1), Resodyn Acoustic Mixers Inc. (Butte, Mont.; demonstrated its new, impeller-free mixing technology, which induces microscale turbulence through the propagation of acoustic waves. Dubbed ResonantAcoustic Mixing (RAM), the now commercially available process promises solutions for many of the complications associated with...

The technology — now being demonstrated at the company’s booth with its lab-scale version (LabRAM) — generates acoustic waves via the resonant vibration of a simple, mechanically driven  agitator. At an 11:00 a.m. press conference today, Resodyn Acoustic Mixers Inc. of Butte, Montana (Booth 211) will be hosting a demonstration of its new, impeller-free mixing technology, which...

    Mixing is one of the oldest unit operations in the chemical process industries (CPI) and can also be one of the most demanding. The complex challenges presented by the wide variety of mixing tasks and scaleup needs encountered in the CPI have been compounded by a rapid rise in reactor size over the last three decades (Table 1). This trend towards larger-scale manufacturing processes has...

    The world's largest pharmaceutical conference and exhibition, Interphex, will be held at the Jacob Javits Convention Center in New York from April 24-26. Approximately 1,000 global companies that serve the pharmaceutical and biotechnical industries will showcase their latest lines of equipment, technologies and services in the areas of manufacturing, sourcing and services, information...

    Mixing of fluids and pasty materials is one of the most fundamental unit operations in chemical engineering. Traditionally an area in which practical experience is often more reliable than calculation, recent years have seen advances in mixing technology of all kinds, not least through the application of computational fluid dynamics (CFD). Today's mixers are superficially similar to those of...

    New crystallization-system designs rely on previous successful installations and rules for scaling-up systems to adapt to slightly different conditions. However, guidelines or rules of thumb have underlying assumptions that might have been ignored when scaling-up a system during the design phase. This practice often leads to difficulties in practical application. This point will be clearly...

By repetitive dividing and merging of laminar flows within complex patterns of narrow (25–40 µm) channels, static micromixers are very efficient at making homogeneous mixtures. However, the narrow channels are susceptible to clogging, and the cost to precisely manufacture the complex patterns remains high. Yamatake Corp. (Tokyo, Japan; has patented a new micromixer...

        When Estee Lauder begin stirring up recipes for facial creams recipes in her kitchen some 70 years ago — the start of a $6.5-billion cosmetics empire that still bears her name — making high-purity emulsions was not the demanding process that it is today. To manufacture cosmetic and pharmaceutical emulsions, such as ointments, crèmes and gels, a wide range of...

Researchers at Kanagawa University (Yokohama, Japan; have developed a three-phase emulsification technology for making stable emulsions of diesel-fuel oil in water. Tests with the emulsion (involving a 30-ton truck) show that fuel-combustion efficiency is increased by 10-15% compared to conventional diesel fuel, and the emissions of dust and nitrogen oxides are reduced by 95 and...

    Fundamental to the chemical process industries (CPI) — whether specialty or bulk chemicals, pharmaceuticals, food products, minerals processing, environmental protection or other products or activities — is the need for mixing. The wide variety and complexity of mixing tasks encountered in industrial applications require careful design and scale up to ensure that effective mixing...
