Extending Existing WirelessHART Networks to Improve Worker and Plant Safety

Jim Cahill

In a Hydrocarbon Engineering article, Emerson’s Amanda Alexander describes two ways to extend existing wireless networks for worker location and toxic gas monitoring. Emerson colleagues who were around back at the dawn of Wireless HART tell me the earliest deployments were usually limited to monitoring applications. At that time there wasn’t a long enough track record of reliability for us to suggest this still-new…

Automating Procedures in Ethylene Furnaces can bring Huge Benefits

Jim Cahill

There are many examples in plants where operators need to follow a particular procedure to safely transition the plant to a new condition. In an ethylene plant, furnace startup, decoke and shutdown operations are classic examples where following strict operating procedures is critical to prevent unsafe conditions as well as promote efficient operations. Since furnaces are decoked every 30-60 days depending on feedstock…

Refinery Optimization Strategies

Jim Cahill

Ensuring that a refinery is flexible enough to accommodate a variety of discounted crudes and adjust production to meet critical customer commitments sometimes feels like walking a tightrope with just the right balance between the financial benefit these crudes offer and the increased fouling and corrosion they cause to a refinery’s assets. In my article, Production levels: Are they all they could be? , in the Refiner…

Choosing the Right Gas Analyzer for Nitrogen Oxide (NOx) Emissions Monitoring

Jim Cahill

NO x is probably the most ubiquitous combustion-created air pollutant since it can be generated by any process burning any fossil fuel, and it is tightly regulated by the U.S. EPA and other regulatory bodies around the world. Plants with relevant combustion processes, including most refineries and chemical processing plants, must monitor NO x output continuously any time fuel is burning. How plants choose to do this is…
