CEP: January 2013 This month's cover story provides loop tuning guidelines to help improve process control and enhance product uniformity. Other articles include: Shale Gas Brightens Outlook for U.S. Chemicals; Streamline Your Process Hazard Analysis; and Optimizing an Organic Rankine Cycle. Also read about the latest developments in energy, nanotechnology, biotechnology, and materials.EditorialWhen reporting on events, writers and editors always need to be mindful of when the reader will receive the publication. This is especially critical for a monthly magazine like CEP. An event that is considered breaking news when we experience it or write about it will no longer be news by the time you get the issue.

Kevin SwiftThe chemical industry will experience moderate annual growth over the next few years — ranging between 2.2% and 4.6% through 2017. The higher growth rate accounts for new investments announced in response to the abundant supply of shale-based... Streamline Your Process Hazard Analysis January2013SafetyMolly R. Myers, Judy PerryA little creativity during preparation — developing checklists, grouping similar processes, pre-populating worksheets, and considering possible deviations and safeguards before meeting face to face — goes a long way toward improving the efficiency and effectiveness of your PHA efforts. Optimizing an Organic Rankine Cycle January2013Heat TransferAli Bourji, P.E., Alan WinsteadAn organic Rankine cycle (ORC) system can be a cost-effective way to convert waste heat to electricity. The key is finding the best ratio of net power recovery to capital cost.
