CEP: Process Safety Beacon - Have You Heard a Pressure-Relief Valve Chatter?
CEP Magazine article, April 2013
Chattering is the rapid opening and closing of a pressure-relief valve. The resulting vibration may cause misalignment, valve seat damage, and, if prolonged, mechanical failure of valve internals and associated piping. Some causes of chattering include: excessive inlet pressure drop; excessive... -
CEP: Material Matters - Using Casting Simulation to Ensure Better-Quality Pumps and Valves
CEP Magazine article, April 2013
Leaks in fluid-containing castings, such as pumps and valves, present major problems for chemical processing plants. To address this issue, the Materials Technology Institute (MTI) funded a casting quality prediction project aimed at developing a method to identify abnormalities in the casting... -
CEP: Patent Update - An Invention's Nonobviousness May Not Be Obvious
CEP Magazine article, April 2013
To qualify for a patent, an invention must be both novel and nonobvious. Novelty requires that the invention differ in some way from the prior art, such as earlier patents and published materials. Nonobviousness requires that there be more than just a difference, such as an element of discovery, or... -
CEP: AIChE Journal Highlight - CO2-Selective Membranes for Carbon Capture
CEP Magazine article, April 2013
The capture of CO2 from flue- and fuel-gas streams in large-scale power generation offers a compelling means to combat climate change. Technically plausible strategies for CO2 capture include post-combustion carbon capture (PCC), oxy-combustion, and pre-combustion carbon capture (PrCC) — all of... -
CEP Editorial: Help Grow AIChE’s Apprentice Program
CEP Magazine article, April 2013
If you are a young professional under the age of 35 and are willing to assume a leadership role in AIChE (on a project of your choice), the AIChE Foundation, through its Young Professionals Apprentice program (CEP, Sept. 2012, p. 72), will subsidize your dues for 2.75 years. The subsidy is 100% in... -

Singapore’s Chemicals Industry: Engineering an Island
CEP Magazine article, April 2013
The chemicals industry is a pillar of Singapore’s economic success. The island city-state’s emergence as a chemical industry leader has been boosted by investment in infrastructure and the creation of an industrial island complex. -
Apply Quantitative Gamma Scanning to High-Capacity Trays
CEP Magazine article, April 2013
Push valves, multiple downcomers, and truncated downcomers boost tray capacities, but they also present troubleshooting challenges. Use quantitative gamma-scan analysis to measure froth heights, froth densities, and blowby in order to solve operating problems with these trays. -
Understand the Basics of Membrane Filtration
CEP Magazine article, April 2013
Membrane filtration is an integral part of many industrial processes, as it is often more environmentally sustainable and cost-effective than other separation technologies
