Ethernet's slow march on industrial automation

Article Abstract:

Ethernet is slowly being utilized for process control as performance and cost issues that hamper its growth in the past are ironed out. Currently, the availability of Ethernet on practically every remote input/output (I/O) modules produced by programmable logic controllers firms and third- party I/O suppliers cannot be denied. Aside from being inexpensive, fast and reliable, Ethernet is also now known as essentially risk-free for office applications.

Get more from your regenerative thermal oxidizer

Article Abstract:

Companies can improve regenerative thermal oxidizers' (RTOs) performance in controlling hazardous emissions by optimizing RTOs' key variables. The variables include bakeout, which lets the RTO temperature on the inlet side of the heat-exchange media to be raised, and variable-frequency drive, which controls pressure to a preset level at the RTO inlet. Fuel injection increases RTO performance when air stream absorbs more heat from the ceramic beds.

A new search tool for complex chemicals

Article Abstract:

Oxford Molecular Group developed the RS3 Discovery, an Oracle-based database program that uses a detailed description of a chemical's physical structure to identify each chemical and all of its associated input data. Procter & Gamble (P&G) cooperated with Oxford in customizing a chemical- information management system to manage data in its toxicology studies. P&G chemists register chemical and pharmaceutical analogs in the centralized database.
