Successful adsorber design requires information about certain adsorbent properties, including: adsorbent densities and void fractions; isotherms or other equilibrium data; and data on mass-transfer kinetics and fixed-bed dynamics. Here, these adsorbent properties are explained, along with corresponding equations. Densities and…

Plant Watch PET resin capacity expands in Saudi Arabia June 15, 2009 — Uhde Inventa-Fischer GmbH (Berlin, Germany) has entered into a contract with the Saudi Basic Industries Corp. (SABIC) to provide the technology license and the basic engineering for…
When a flowmeter is needed, the selection process should include studying the characteristics of respective measurement technologies and analyzing the advantages/disadvantages for different plant environments. This effort will help ensure that a meter with the right performance and reliability, for…
The heat transfer sufaces of coal-fired process heaters and boilers often undergo severe fouling. If left intact, such deposits, consisting of slag from mineral matter contained in the coal, can reduce heat-transfer-surface availability, reduce thermal efficiency and cause corrosion. If…
Despite the immense value and universal appeal of these additives for product designers, process engineers facing the day-to-day reality of full-scale production face a unique set of challenges. Dispersing these powdered additives into a liquid is one of the most…
“When you improve the efficiency or capacity of a product, it almost always can be used to improve the process economics with respect to investment costs or operating costs,” says Mark Pilling, manager of technology with Sulzer Chemtech (Tulsa, Okla.).…
