Don’t Overlook Composite FRP Pipe

    There are several reasons why composite fiberglass-reinforced-plastic (FRP) pipe has been replacing conventional pipe, and why this still relatively new material (see box, p. 46) should be kept in mind whenever piping is being specified for a new…

Preventing Fires and Explosions in Pilot Plants

    Among pilot plants, those in petrochemical or petroleum-refining service pose special risks of fire and/or explosion. The key strategies to minimize those risks are these: properly conducted preconstruction safety reviews; leaktight design and construction; close attention to area…

A Bit of Extra Lab Effort Can Prevent Grief During Scaleup

    It’s an old saw, but I’ve long held that process development is very much a team effort. Developing safe, robust and scaleable chemical processes calls for close collaboration between synthesis chemists, process development engineers and pilot plant personnel.…

Chementator: Jet fuel

Researchers at Penn State University’s (University Park, Pa.; edlinks.chemengonline.com/5829-551) Energy Institute are developing a jet fuel that is composed of at least 50% bituminous coal. The fuel, provisionally designated JP900, is comparable to Jet A or military JP 8, and…

Chementator: Plant security

BroadWare Technologies, Inc. (Santa Clara, Calif.; edlinks.chemengonline.com/5829-548) and Intergraph Corp. (Huntsville, Ala.; edlinks.chemengonline.com/5829-549) have created an integrated solution that feeds high-quality video from remote locations to a central command center to speed decisionmaking and response time when a security event…

A new NGL-extraction process makes its commercial debut

Toyo Engineering Corp. (TEC; Tokyo; edlinks.chemengonline.com/5829-536) has developed a new, cryogenic process for extracting natural-gas liquids (NGLs; ethane, propane, butane and other hydrocarbons) from liquefied natural gas (LNG). The Coreflux-LNG process boasts an ethane recovery efficiency of around 98%, compared…

A multilayered, self-sensing diaphragm for metering pumps

Mechanically driven diaphragm pumps (MDDPs) are widely used for metering applications in the chemical process industries. But because the pressure difference between the drive and the delivery side gives rise to tensile loads in the flexing zone of the diaphragm,…
