A novel cold-dry process makes possible the utilization of fine form-factor silicon, such as granules and sand-like fines, in the production of high-purity polysilicon for solar photovoltaic cells and semiconductors, where such fine-grained material would normally have to be sent…
Peristaltic pumps work by compressing a tube against a circular pump housing with rollers on a rotating arm. The fluid that is ahead of the roller gets pushed forward, while new fluid is drawn into the tube by the vacuum…
A three-piece, stainless-steel ball valve features this company’s Smart Connect feature for joining pipes without welding. The ball valves are available in two grades of stainless-steel grades (304 and 316), in sizes from 0.5 to 2.0 in., and with more…
One additive intended for use in lead-acid batteries for micro-hybrid gasoline engines, and another for lithium-ion batteries in electric vehicles, can improve battery performance. PBX51 is a performance additive designed to improve performance and lifetime for lead-acid batteries requiring high…
The Model TG-300 variable-speed low-flow pump is a positive displacement gear pump designed for smooth, continuous flows from 0 to 400 mL/min (0–5 gal/h). Fluids compatible with aluminum, steel, Viton and Teflon-wetted materials and viscosities of 30–600 cSt can be…
The HydroWhirl S tank washing nozzle range has been expanded to include ATEX-certified versions for use in atmospheres that are potentially explosive, while also meeting requirements for gas and dust approvals for all zones (0, 1 and 2). The HydroWhirl…
New biocomposite plastics that combine soybean-meal protein with conventional plastic resins allow significantly lower use of petroleum-based chemicals in polyethylene (PE) and polypropylene (PP) manufacturing. The new class of bioplastics incorporates soybean-meal protein, which is chemically bound to the PE…
The Atlas Syringe Pump XL allows automated volumetric dosing from 100 µL/min to 200 mL/min. The pump features two syringes that can be independently controlled or combined to enable continuous flow at pressures up to 6 bars. The pump is…
A Samsung petrochemicals facility in South Korea will be the first to feature a suite of energy efficiency technologies developed by UOP LLC (Des Plaines, Ill., www.uop.com) for improved aromatics production. A number of UOP aromatics-processing design features and materials…
A new process for generating sheets of polyethylene terephthalate (PET) eliminates several production steps used in the traditional process, offering greatly reduced energy use and improved polymer properties. Developed by Octal Petrochemicals LLC FZC (Muscat, Oman; www.octal.com), the direct-to-sheet PET…
