A research team, led by Jongsoo Jurng and Gwi-Nam at the Korea Institute of Science and Technology (Seoul; www.kist.re.kr), has developed a nano-catalyst filter that can drastically reduce harmful substances in cigarette smoke. The team created the filter by evenly…
Japanese companies INPEX Corp. (Tokyo, www.inpex.co.jp), Chiyoda Corp. (Yokohama; www.chiyoda-corp.com), and Metawater Co., Ltd. (Tokyo, all Japan; www.metawater.co.jp) have been commissioned to build a small-scale demonstration facility that will use ceramic membrane filtration for treating produced water for Japan Oil,…
The seven commonly made mistakes discussed here often lead to poor filtration and separation performance and many associated problems For almost any chemical process industries (CPI) plant, contamination is a reality that can cause numerous associated — and often chronic…
New materials and designs help processors improve efficiency and reliability As in other areas of chemical manufacturing, processors want more efficiency from their distillation and mass-transfer operations. Increasing capacity, finding solutions to issues such as foaming and fouling that slow…
Some of the many things to consider for the complex task of performing a column revamp are presented in this cover story Petroleum refineries, chemical-processing plants, natural-gas purification plants and other facilities in the chemical process industries (CPI) all contain…
A cement plant in Taiwan has been retrofitted with the largest CO2-capture plant to use calcium-looping technology to date. The project, run by Taiwan’s Industrial Technology Research Institute (ITRI; Hsinchu, Taiwan; www.itri.org), demonstrates ITRI’s high-efficiency calcium-looping technology (Heclot) at a…
Process simulation methods are used to evaluate the performance of proposed distillation systems and improve the performance of existing ones. The most common approaches for modeling distillation processes can be broadly divided into equilibrium and non-equilibrium methods. This article provides…
The Andritz Group This new belt press for dewatering in municipal and industrial applications is based on a new low-profile design and flexible modular construction. The size and weight of the press is about half that of the previous machine…
Fabricated metal-wire mesh is one of the major categories of filter media. Woven metal cloths are often used to support a filter aid coating or a bed of granular or porous material. Proper selection of wire cloth can have a…
Many applications in the chemical process industries (CPI) require filtration — from cleaning the air of dust, to corrosion prevention, to cleaning up incoming process water, to recovering proteins downstream. No matter the application, filtration providers are working to improve…
