Crystallization is a key purification technique for various sectors of the chemical process industries (CPI). Several approaches for industrial crystallization have evolved over time, and highly specialized crystallizer designs have been developed, especially in long-established industries. Solution crystallization is an important unit operation because the process can generate high-purity products from...

A rapid and ongoing expansion of polysilicon production capacity will likely generate an oversupply for the next several years, driving polysilicon manufacturers to further innovate processes and reduce operating costs in preparation for an impending wave of new demand. Drastic price drops experienced in 2009 are expected to continue at a slower pace in 2010, yet polysilicon producers remain poised to...

With the exception of Oslo-type crystallizers, the main commercial crystallizers are agitated systems that use an agitator [agitated tank or draft-tube baffle (DTB)] or a circulation pump [forced circulation (FC) crystallizers]. In such systems, however, large crystals become damaged by the pump or impeller, which leads to the generation of fines, says Michel Malfand, president of Crystal Evap consult...

The need to conserve water is becoming a common concern throughout the world. Whether this is due to the cost of water, availability of water, or environmental concerns, water conservation is becoming a major focal point, both in the public and private sector. In those areas where renewable water resources are limited, and in regions where there are significant environmental concerns and costs associated...

Crystallization is a method of solid-fluid separation in which pure chemical crystals are formed. Crystallization kinetics consists of three major phenomena: nucleation (the birth of a crystal), transfer of the solute from the supersaturated solution to the crystal surface, and a reaction during which the solute becomes incorporated into the crystal. Supersaturation In order to drive the process of...

A simpler and more-efficient way to obtain purified terephthalic acid (PTA) has been developed by GTC Technology (Houston, Tex.; edlinks.che.com/6895-537). In conventional PTA production, p-xylene is oxidized to crude terephthalic acid (CTA), then purified by hydrogenation in an aqueous solution. Hydrogenation converts the main impurity, 4-carboxybenzaldehyde (4-CBA), to p-toluic acid, which is more readily...

    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...

Most of today's solar cells are made from silicon wafers cut from blocks of crystals. The wafers are typically 0.2-0.25-mm thick, yet most of the photon-to-electricity conversion takes place in the outermost 0.02 mm of the wafer. In an effort to reduce the amount of Si required (and thus the cost) for solar cells, BP Solar (Frederick, Md; edlinks.che.com/6517-538) is supporting a three-year research...

Sodium chloride aerosols are widely used as part of bronchial provocation tests to identify people with asthma, and those who wish to enter military or police service. To maximize their effectiveness, salt aerosol crystals should be as small as possible (< 5 μm dia.), but current production methods, such as milling, spray drying, and antisolvent crystallization, tend to produce NaCl particles that...

Process System Enterprise Ltd. (PSE; London, U.K.; edlinks.che.com/5825-542) has launched the latest of a series of gPROMS Advanced Model Libraries (AMLs) for Gas-Liquid Contactors (GLCs). This “open model” library of high-fidelity, non-equilibrium-component models covers a wide range of gas-liquid-separation operations, including conventional packed columns for...
