http://www.che.com Chemical Engineering en-us 2013 Sun, 26 May 2013 0:12:23 EDT Waste heat recovery (WHR) is essential for increasing energy efficiency in the chemical process industries (CPI). Presently, there are many WHR methods and technologies at various stages of implementation in petroleum refineries, petrochemical, chemical and other industry sectors. Increasing energy costs and environmental concerns provide strong motivation for implementing more and newer methods and technologies for WHR. The main objective of this article is to provide a review of promising methods and technologies for WHR (up to 400C) as a ready resource that can be used for better understanding and preliminary selection of suitable WHR techniques.... http://www.che.com/extras/web_extras/10084.html Tue, 1 Jan 2013 0:00:00 EST   Weftec 2012, the Water Environment Federation’s 85th annual technical exhibition and conference, attracted over 17,000 attendees on September 29 – October 3, 2012 at the Morial Convention Center in New Orleans, La. With 980 exhibiting companies, the following is a small sampling of... http://www.che.com/extras/web_extras/9930.html Thu, 1 Nov 2012 0:00:00 EDT Higher margins on steam-cracking ethane to produce ethylene have resulted in an expansion of ethylene capacity to take advantage of the increased availability of ethane from natural gas. The shift toward ethane feedstocks for ethylene is generating a number of ripple effects, including tightness in the propylene and butadiene markets. Meanwhile, as manufacturers take advantage of lower energy costs offered by shale gas, other companies pursue alternative routes to ethylene using methane... http://www.che.com/extras/web_extras/9834.html Mon, 1 Oct 2012 0:00:00 EDT The recently published list includes books on brittle materials, physical and chemical equilibrium, surfactants and interfacial phenomena, ionic interactions, distillation engineering, and more.... http://www.che.com/extras/web_extras/9439.html Sun, 1 Jul 2012 0:00:00 EDT Peristaltic pumps for abrasive materials applications; Diaphragm metering pumps for water applications; Gentle material transfers are this pump's specialty; Pumps that satisfy both E.U. and U.S. standards; and more... http://www.che.com/extras/web_extras/9278.html Tue, 1 May 2012 0:00:00 EDT Already, in the first two months of this year, the unpredictable and winding road of the so-called Boiler MACT, has taken yet another set of hair-pinned curves. Now industry groups are pushing even harder for an act of Congress that would put on the brakes and allow more time for the regulations to be... http://www.che.com/extras/web_extras/9025.html Thu, 1 Mar 2012 0:00:00 EST One of the reasons that Chemical Engineering will have the honor of celebrating its 110th anniversary this year is its longstanding reputation for original, noteworthy and unbiased articles that cannot be found anywhere else. Our internal policies help protect the magazine’s reputation from a number of... http://www.che.com/extras/web_extras/8944.html Wed, 1 Feb 2012 0:00:00 EST A limit controller that is suited for oven applications; A new mass flow controller expands this series' flow range; New digital pressure gage offers simple set up and readability; and more... http://www.che.com/extras/web_extras/8837.html Sun, 1 Jan 2012 0:00:00 EST Large-scale energy storage technologies offer the opportunity to optimize the efficiency of the next-generation power grid and extend its capabilities. Renewed attention on energy storage systems for the power grid has given rise to a host of emerging technologies aimed at more effectively transmitting electricity not only across space, but through time.... http://www.che.com/extras/web_extras/8746.html Thu, 1 Dec 2011 0:00:00 EST This article presents equations that allow the user to calculate liquid volume as a function of liquid depth, in both vertically and horizontally oriented tanks with dished heads. The equations accommodate all tank heads that can be described by two radii of curvature (torispherical heads). Examples include... http://www.che.com/extras/web_extras/8471.html Thu, 1 Sep 2011 0:00:00 EDT
