The growth in use of centrifugal compressors in chemical process industries (CPI) applications in recent decades has been brought about by four factors: 1) advances in dry gas seal technology; 2) modern aerodynamic, rotor-dynamic and thermodynamic knowledge and techniques; 3)…
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…
