Continuously Monitoring for Pipeline Corrosion

The need for pipelines to get oil & gas from producing regions to processing and distribution areas in the global supply chain continues to grow. Monitoring for corrosion is critical to prevent safety and environmental incidents.

This 3 ½ minute YouTube video, Roxar FSM Log 48 Area Corrosion Monitor shows how this technology permanently monitors a pre-defined pipeline area—improving pipeline integrity management (PIM) programs that traditionally rely on infrequent and offline techniques such as in-line inspection (ILI), direct assessment (DA) or hydrostatic pressure tests (HPT).

Highly Accurate Continuous Emissions Monitoring

Continuous emission monitoring systems (CEMS) are used by manufacturers and producers that have combustion and other forms of emissions releases as part of their processes. These systems provide the information required for regulatory reporting.

A recent news announcement, Emerson’s New Hybrid Laser Process Gas Analyzer Reduces Costs for Continuous Emissions Monitoring, describes purpose-built technology to replace legacy measurement systems. At the heart of this CEMS is a high-accuracy Rosemount CT4400 Continuous Gas Analyzer that requires no consumables and minimizes maintenance.

In this news release, Emerson’s Paul Miller explained:

Our customers are looking for a better way to measure emissions without the on-going high costs or need for frequent calibration and complex sample preparation that requires NOx converters or ozone generators… The Rosemount CT4400 Continuous Gas Analyser gives them an answer to their exact requirements in a configuration they can just plug into their existing systems and be off and running – at a lower cost than previously possible. The reduced complexity of the system over what most companies are used to, results in higher reliability and analyser availability with a lot less personnel time required.

Controlling Surge in Centrifugal Compressors

Centrifugal and axial compressors can experience a potentially destructive condition known as surge. Emerson’s Mikhail Ilchenko describes it for me.

Surge is a condition that occurs in compressors when the amount of gas they are trying to compress is insufficient for the size of the compressor and the blades lose their ability to transfer energy from the shaft to the fluid, causing a reverse flow of the gas. This condition can have catastrophic effects on the machine, so compressor manufacturers include anti-surge valves that recycle gas from the discharge to the suction when a low flow is detected. Usually compressors are designed such that these valves are only open on startup or under reduced rates.

Easier Installation and Ongoing Operation with 2-Wire Coriolis Transmitter

There are many flow measurement technologies from which to choose. We discussed the advantages of Coriolis flow and density measurement technology in many applications in earlier posts.

A short 3:23 YouTube video, 4200 2-Wire Coriolis Transmitter shares how this 2-wire transmitter innovation allows easier replacement of existing flow measurement technologies without the need to run separate power cables.

Less wiring means saving on cabling and wire termination costs, as well as the associated design & engineering costs. The 4200 transmitter is completely configurable with the local display at the transmitter without the need for a hand-held configurator or additional software. Continue Reading

Building IIoT-Powered Condition Monitoring Business Case

The costs and difficulties associated with wiring and terminations have historically limited the sensors used in manufacturing and production processes to only the most essential measurements. Industrial Internet of Things (IIoT)-based wireless devices have fundamentally changed this reality.

However, more data from these sensors does not automatically translate into better business performance. It takes analysis and recommended actions & changes in work processes to improve performance in areas such as safety, reliability, efficiency & emissions, and production.

Connected Services by experts is an immediate way to turn this additional data into improved performance. In this recorded webinar, The Business Case for IIoT-powered Condition Monitoring, Emerson’s Mike Boudreaux addresses how to develop the business case for a formal reliability program aimed at reducing downtime through condition monitoring.

Webinar: Developing Business Case for IIoT-Powered Condition MonitoringMike highlights 4 steps in building this business case:

  1. Develop a condition-monitoring strategy
  2. Estimate the value
  3. Determine the cost
  4. Calculate the return on investment

Develop a condition-monitoring strategy

There are two common options for developing this strategy. The first is as part of a formal reliability program that is broad in scope and applied across the entire operation—within or across facilities—and the second is to build a business case for individual investments in condition monitoring on specific types of critical equipment.
