MARCH 2008 • VOLUME 71, ISSUE 3 26 Maintenance and Operations The new U.S. Chemical Facility AntiTerrorism standards target sites that manufacture, use, store or distribute certain chemicals above a deﬁned quantity. However, companies aren’t familiar yet with how to most effectively and painlessly do the required assessments. Feel secure about vulnerability assessments 29 The door opens for membranes Solids and Fluids Handling Zeolites and other inorganic thin-ﬁlm gas separation membranes suffer from a perception problem about their commercial prospects. However, academics predict such membranes may reach the market within three to ﬁve years. Advances extend beyond zeolites to inorganic membranes such as palladium and its alloys and mixed-matrix membranes such as zeolite-polymerics. Distillation is bubbling 20 7 9 Cover Story A weaker dollar is helping chemical exports. With capacity utilization hovering at around 80%, plants are intent on asset optimization. Because distillation often plays a crucial role, many sites are making signiﬁcant efforts to enhance column performance. COLUMNS From the Editor Expect action on greenhouse gases. DEPARTMENTS 13 In Process • Think small for gas storage • Membrane boosts ethylene production • Tiny sensor detects hazardous chemicals 33 Achieve effective heat exchanger control Instrumentation and Control The ﬁrst of a four-part series explores the nuances of steam supply control. Most modern designs are model-based and the relationships in the model allow generating a graph known as the process operating line that’s the basis for evaluating the control issues.
