NOx reduced with controlling fuel/air ratio with Emerson Coriolis Meter
Installing Coriolis meters as part of air-fuel ratio control systems in more than 70 installations has solved many problems in antiquated natural gas piston engines that drive natural gas compressors. In addition to a payback as short as four months, the benefits include direct mass flow measurement, reduced maintenance, lower fuel consumption (15-20%), lower emissions (typically greater than 50%) and reduced engine wear.

Modernizing Old Plants to Meet New Demands
Much of the maintenance inspection in power plants is manual. Energy is wasted by steam loss and inefficiencies. Not all air and water emissions are checked. Imagine instead a power plant full of sensors that continuously monitor the condition of pumps and fans, detecting failure of steam traps or leaking relief valves, and where all emissions are monitored. Instead of operators collecting the data, the data comes to the operators. Much of the maintenance inspection in power plants is manual. Energy is wasted by steam loss and inefficiencies. Not all air and water emissions are checked. Imagine instead a power plant full of sensors that continuously monitor the condition of pumps and fans, detecting failure of steam traps or leaking relief valves, and where all emissions are monitored. Instead of operators collecting the data, the data comes to the operators. Power plants are being modernized with a pervasive sensing infrastructure for a second layer of automation. This is a new strategy for maintenance, energy efficiency, risk reduction and optimization using sensors which require no wires and are mostly non-intrusive and therefore can easily be deployed. Specialized diagnostic software in a separate system distills the raw sensor data into actionable information, such as which equipment needs service and which does not. Wireless sensor networks and analytic software are new technology trends enabling new levels of availability, energy efficiency, environmental compliance and productivity. Pervasive sensing infrastructure is the basis for the Internet of Things, which will take sensing even further in the future.

Emerson Actuator replacement solves turbine bypass problem
As often as four times a year during winter months, a power plant in Wisconsin would miss a scheduled start of its combined cycle power plant due to malfunctions of the turbine bypass valves. This article describes how the problems were solved by replacing the actuation components on those valves.
