The IoT is Reality in Industrial Applications

to connect vibration, acoustic, level, position and other sensors to an asset management system via both a wireless mesh network and a wired Fieldbus network.

“In the industrial sector, hundreds of millions of connected sensors are currently installed with millions more coming online annually”

The asset management system analyzes the big data from the sensors and transforms it into actionable information which is delivered to plant personnel in one of two ways. Control room operators view this information on their PC-based human machine interface monitors, as do other plant personnel on office PCs connected to the Ethernet plant network. Mobile workers view this information on handheld industrial PCs connected to a plant wide Wi-Fi network powered by Cisco industrially-hardened access points.

The following reduced CapEx costs were realized:

► Significantly reduced sensor installation costs using

wireless networks

► Calibration checks that are four times faster, but require only

one-third as many staffers, and

► Wired and wireless networks reduced wiring costs and

improved diagnostic capabilities as compared to traditional

hardwired solutions

And these OpEx benefits were realized:

► Increased production capacity while avoiding capital

investments through wireless tank level monitoring

► Improved safety through vibration monitoring in

difficult to access locations, and

► Energy savings enable by wireless steam trap

Monitoring.

Now that the infrastructure is in place at Ergon’s facility for data collection, analysis and distribution—it’s a simple matter to add other wireless sensors to leverage the initial investment and create more value.

Many other industrial facilities are implementing their own industrial IoT, and one such application is steam trap monitoring via wireless acoustic transmitters. Acoustic sensors and specialized big data, software analysis systems, often located remote from the plant and connected to the sensors via the Internet, detect steam trap problems automatically and alert plant personnel so they can take action.

By monitoring a plant’s steam trap and its steam distribution system automatically and continuously via an IoT application, energy losses costing up to $30,000 annually per steam trap can be eliminated. As many plants have scores of steam traps, savings can be considerable.

For example, a plant was experiencing a 15 percent annual steam trap failure rate, with 12.5 percent of the plant’s steam traps responsible for 38 percent of the steam loss. Correcting this issue with wireless steam trap acoustic sensors and accompanying big data analytics resulted in an annual savings of $301,108 and a payback period of just a few months.

Another industrial IoT example is monitoring valves controlling gas flows to flare stacks in refineries. Using wireless acoustic transmitters, one refinery was able to improve regulatory compliance and reduce hydrocarbon losses by $3 million annually due to timely detection and repair of faulty valves. The project paid for itself in five months, with an estimated annualized ROI of 271 percent annualized over 20 years.

In the commercial realm, the IoT is in the conceptual stage, with many possible permutations discussed—but with few installations up, running and delivering value. But in the industrial sector, hundreds of millions of connected sensors are currently installed with millions more coming online annually.

Many of these sensors are wireless because they cost much less to install than their wired equivalents. These low cost wireless sensors are securely connected via mesh networks to systems performing big data analytics to dramatically improve plant performance, resulting in payback periods measured in months, with ongoing savings afterwards.
