CEP: AIChE Journal Highlight - New Model Optimizes Water Use in Shale Gas Development

June
2015
Journal Highlight
In the June AIChE Journal cover story, “Investment Optimization Model for Freshwater Acquisition and Wastewater Handling in Shale Gas Production,” Linlin Yang, Ignacio E. Grossmann, and Meagan Mauter of Carnegie Mellon Univ., and Robert Dilmore of the National Energy Technology Laboratory, discuss a new mixed-integer linear programming (MILP) model to optimize water use in the hydraulic fracturing of shale gas in the Marcellus and Utica shale plays. The objective of the model is to minimize the capital and operating costs and maximize profit.

CEP: Catalyzing Commercialization - High-Performance MOFs Improve the Economics of Industrial Gases

June
2015
Catalyzing Commercialization
The highly commoditized industrial gas sector relies on energy-intensive processes to produce, separate, and store industrial gases. The power required to compress gases accounts for up to 50% of the cost of the delivered gas. And, gas-separation adsorption units recover only a fraction of the feed product, necessitating processes with large waste or recycle streams. NuMat Technologies, an Illinois startup has developed synthetic adsorbent materials to address these challenges.

CEP: Process Safety Beacon - Conduct of Operations

June
2015
Process Safety Beacon
Conduct of operations can be summarized in two simple concepts: (1) Say what you intend to do (procedures). (2) Always do what you say. This means, for example, that if your operating procedures say to shut down if a critical safety parameter exceeds a specified value, you must always shut down.

CEP: Process Safety Beacon - Mechanical Integrity

May
2015
Process Safety Beacon
An effective MOC system is vital to the success of any piping integrity management program. Your plant inspection group can anticipate changes in corrosion or other deterioration and change inspection schedules and procedures appropriately. Make sure your inspection group is involved in the approval process for changes that may affect the integrity of piping or other equipment.

CEP: Catalyzing Commercialization - Enabling a New Generation of Polyolefins

May
2015
Catalyzing Commercialization
With a global production of 150 million metric tons in 2013, polyolefins represent the largest class of synthetic polymers. Today, the industry uses a costly, time-consuming, “one catalyst, one material” trial-and-error approach to developing new polymers. Precision Polyolefins (PPL) intends to change the status quo by establishing a novel “one catalyst, many materials” paradigm for rapid discovery and product development of new polyolefins.

Energy Management and Efficiency for the Process Industries

April, 2015
Editors Alan P. Rossiter and Beth P. Jones have gathered material that lays out the underlying management and technical issues that drive successful industrial energy management program. With a foreword by the Hon. Charles D. McConnell, former assistant secretary of the U.S. Department of Energy, the book provides a clear understanding of both scope of the opportunity and the available methodologies for capturing energy savings.

Saudi Arabia’s Chemicals Industry Continues to Grow

August
2014

Leonard E. Gerlowski, Ahmad M. Al Othman
Abundant and competitively priced petroleum feedstock has spurred massive growth in Saudi Arabia’s chemicals industry over the past five decades. As the Kingdom faces competition from neighboring countries, it will diversify to ensure further growth.

CEP: Process Safety Beacon - Safe Work Practices

April
2015
Process Safety Beacon
The term safe work practices refers to the processes we use to authorize nonroutine work activities, and to control the hazards and manage the risks associated with these activities. Safe work practices often authorize work through permits, which frequently include checklists of potential hazards associated with the work. A nonroutine activity has nothing to do with how often the activity is done. Instead, it refers to activities that are not part of the normal process for converting raw materials to finished product, and not covered by the plant’s standard operating procedures for normal operations.

CEP: Catalyzing Commercialization - Nanocrystal Manufacturing May Revolutionize Thermoelectrics

April
2015
Catalyzing Commercialization
Thermoelectric materials hold promise as a means to recover waste heat from automobile exhaust, power plants, and other systems. Their use, however, is limited by low efficiency. Researchers at Rensselaer Polytechnic Institute have developed a process that combines nanostructuring, compositional control, and ppm-level impurity doping. ThermoAura, Inc., a start-up company co-founded by the researchers, has scaled up this process to manufacture high-performance thermoelectrics with tunable properties.

Material Matters
Kirk Richardson
To provide guidance and disseminate reactivity data, the National Oceanographic and Atmospheric Administration (NOAA), in conjunction with partnering companies and technical associations, developed the Chemical Reactivity Worksheet (CRW). The free software ( http://response.restoration.noaa.gov/reactivityworksheet ) allows CPI professionals to review the reactivity hazards of thousands of individual chemicals, as well as predict the consequence of mixing chemical substances. Since its release in March 2013, the CRW Version 3 (CRW3) has been downloaded approximately 80,000 times.

CEP: AIChE Journal Highlight - Layer-by-Layer Approach Enables Customizable Medication Therapy

April
2015
Journal Highlight
In the April AIChE Journal Perspective article, “Layer-by-Layer Approaches to Staging Medicine from Surfaces,” Paula T. Hammond of the Massachusetts Institute of Technology describes her research on a method that creates layers of thin films stacked on top of one another. Each layer contains a different therapeutic, which is incorporated into the thin film via one of several mechanisms (e.g., charge, hydrogen bonding, or other complementary interaction). This technique is useful for drug therapy in applications such as bone regeneration.

AIChE Journal Highlight - Red Blood Cells Disguise Nanoparticles for Biomedical Applications

March
2015
Journal Highlight
Nanoparticles (NPs) loaded with therapeutics provide a way to target the delivery of drugs to specific locations in the body. When injected intravenously, however, nanoparticles are often recognized by the immune system and rapidly cleared from the body. Efforts to extend their residence time in vivo have focused on modifying particle surfaces to evade the body’s natural defenses. Polyethylene glycol (PEG) is currently the gold standard for such nanoparticle stealth coating, but the recent observation of an anti-PEG immunological response has spurred the search for improvements. To address this challenge, researchers have looked to nature, which has created the ideal drug-delivery vehicle — red blood cells (RBCs).
