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…
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…
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…
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…
Maximum ease of cleaning, maintenance and internal inspection are the qualities that make the CosmoDry System suitable for multi-product applications. The CosmoDry System consists of a horizontal cylindrical chamber, equipped with a concentric agitator, fitted with a heated shaft that…
Sorbent materials are used commercially for bulk separation, as well as purification of both liquids and gases. This one-page reference provides manufacturing and application information on the most widely used industrial sorbent material — activated carbon. Four types of generic…
A dividing wall column (DWC) is an atypical distillation column with an internal, vertical partition wall that effectively accommodates — within one shell — two conventional distillation columns that are connected in series as required when separating a multicomponent feed…
New distillation columns are getting much larger. The history of column sizes, and design and construction issues associated with large columns were recently addressed at the AIChE Spring Meeting (New Orleans, La.; March 30 to April 3) by Dan Summers…
