Emerson shows off their latest instruments

The Emerson European Exchange User Meeting in Brussels in April 2016 presented their approach to large automation projects, ‘Project Certainty’, as the main thrust of the conference and press event associated with the meeting. This approach will be reported separately: this view of the instrumentation developments on show was the topic of my column about this event, published in the SA I&C Journal in June 2016. The story is shown below.

The Emerson European Exchange

Maybe half the audience for the first Emerson presentations

The Emerson ‘Global User’s Exchange’, for their customers and potential customers in Europe, Middle East and Africa, was held in Brussels in April. As with all the leading Automation, Control and Instrumentation suppliers in the world, Emerson Process Management has developed this style of single company Expo, because it is difficult to present their whole product range and capability in any commercial, third party exhibition: there would not be enough space. Indeed even in their own dedicated display hall, not all their product capability was on show.

The same is true of the presentations and keynote speeches. The Emerson business is so big, based on large automation projects, that these have to be the main focus of the management comments. The fascinating detailed product and technology developments in temperature, analytical or corrosion instrumentation also on show, did not get top billing, but they were there, in the background.

I have to declare that I need to understand a product or technology to become enthusiastic about it, and in general I have found instrumentation easier to understand than automation software. Emerson has always put an emphasis on instrumentation, and invested in this by developing or acquiring innovative new techniques and companies in the area – moreso than most of the other majors. Then by adding their own knowledge power, they add interfaces and capability, such as HART and Wireless communications, manufacturing technology, housings and mods for industry-wide approvals. So I am an Emerson fan. But because technology grows, it does become harder to understand the way these instruments actually work! For me, a visit to the Emerson Expo is like opening a treasure chest, filled with ideas and enthusiastic people available to explain their latest kit.

Wireless interfaces link everything

The Emerson dedication to WirelessHART communications with all instrumentation, as a standard option, opens up the possibility of adding modern technology sensors into existing plant and processes without the major hassles of adding new cables.

Emerson 12-3-1550855bRosemount temperature sensors have had a wireless capability from ‘Day 1’ of the wireless era: and various companies made such wireless sensors capable of being clamped or strapped to the outside surface of a pipe, to make them totally non-intrusive, and easily re-positioned. The Rosemount engineers have gone one step further, recognizing the measurement errors possible with an external sensor affected by the environment. They have developed X-well technology, available with a clamp for pipe ODs between 0.5” and 48”, which incorporates a layer of thermal insulation 13mm thick and covering a 12” length of the pipe (this is not shown in the picture). All this helps to bring the temperature sensor measurement closer to the actual pipe contents temperature, but in addition the electronics senses the ambient temperature, and uses a thermal conductivity algorithm to make a further correction, before transmitting the data over the wireless link.

WirelessPressureGaugeSimilarly, Rosemount lateral thinking has applied wireless technology and piezo-resistive pressure measurement to the pressure gauge. This modern design of an ancient instrument replaces the original Bourdon tube measurement element with a modern sensor capsule, which uses the battery power to drive a needle around a 270 degree scale on a 4.5” indicator. Then the WirelessHART connection transmits the actual process pressure to a central monitoring system. This new indicator gauge is much safer than the old design – with two layers of process isolation from the gauge body it can withstand a 150x overpressure, and is much less affected by plant vibration.

Emissions Monitoring

One of the most advanced product ranges demonstrated in Brussels came from Cascade Technologies, of Stirling in Scotland, which was acquired for Rosemount Analytical at the end of 2014. Cascade have developed some clever laser based systems for gas analysis, for example for Continuous Emissions Monitoring (CEM) systems, which allows them to measure for multiple gas types simultaneously. In the words of one of the experts they effectively have up to 9 lasers operating at different frequencies in one analyser, enabling monitoring for a similar number of gas concentrations. Similar systems have been used to monitor up to a total of 20 gases simultaneously. Their enthusiastic engineers were saying that following the Emerson involvement in the company they would be launching four new products this year – in fact the next one of these was reported on here, in a ProcessingTalk.info review, last month!

Enardo_950_w-bracketAnother essential, but older, safety and emissions monitoring product range has been updated by the addition of an Emerson WirelessHART data link. In 2013, Emerson acquired Enardo, a Tulsa-based manufacturer of mechanically operated pressure and vacuum relief valves, which are used to protect storage tanks for oil/gas, petrochemical and pharma plants – Enardo is now part of the Fisher Regulators business. These valves relieve the tank vapour pressure when the tank is filled, or the temperature rises, or allow air to enter as the tank is emptied, preventing any pressure damage to the tank walls. But safety concerns and modern emission regulations require the valve actions to be monitored: and with no existing wiring installed to transmit such signals, the WirelessHART systems provide a simple solution.

Corrosion monitoring

It was way back in 2009 when Emerson acquired Roxar of Norway, who then specialised in systems for monitoring offshore wells and oil pipelines. The technology involved in the Roxar sensors has developed a long way: they don’t just use ultrasonic detectors to measure the sound of sand and grit hitting the pipe walls! The ER corrosion sensors use a probe with a thin, exposed electrical conductor embedded in an insulator, inserted in the pipe wall. Corrosion of this element changes the resistance of the conducting path, which is monitored. Various designs are available, to adjust the sensitivity of the sensor. LPR probes are Linear Polarisation Resistance probes, which are electrochemical, so require the presence of a conductive liquid, like water, to function. The current response achieved when a small (10-20mV) known polarisation is applied between the electrodes exposed to the liquid, gives the corrosion rate, using electrochemical theory. These Roxar sensors with their CorrLog electronics are now available with WirelessHART communications, making them much easier to apply to any pipework area that is considered at risk from corrosion – and for modern plants using different sources and compositions of feedstock, the corrosion rates can vary significantly from one batch to the next.

Hybrid Laser Continuous Gas Analyser

Emerson has announced the release of the Rosemount CT5100 continuous gas analyser, the world’s only hybrid analyser to combine Tunable Diode Laser (TDL) and Quantum Cascade Laser (QCL) measurement technologies for process gas analysis and emissions monitoring. The CT5100 is the latest offering in the Emerson CT5000 series, providing the most comprehensive analysis available as it can detect down to sub ppm level for a range of components, while simplifying operation and significantly reducing costs. Unlike traditional continuous gas analysers, the CT5100 can measure up to 12 critical component gases and potential pollutants simultaneously within a single system – meeting local, national, and international regulatory requirements.

The CT5100 was first shown at the Emerson European Exchange in Brussels, last month, and is one of several new developments to be launched this year, following the acquisition of the company Cascade Technologies, of Stirling in Scotland in December 2014.

QCL-Image-CT5100-Ex-160420

The CT5100 operates reliably with no consumables, no in-field enclosure, and a simplified sampling system that does not require any gas conditioning to remove moisture. The new gas analyser is ideally suited for process gas analysis, continuous emissions monitoring, and ammonia slip applications.

“The increase in regulatory requirements worldwide, along with the decrease in experienced personnel in industrial plants, have paved the way for the emergence of a new generation of faster, more accurate, and easier-to-use measurement technologies,” said Ruth Lindley, product manager for QCL analysers at Emerson. “The CT5100 represents an important next step in that direction, providing unmatched sub-second response time for precise, reliable measurement of complex gases and emissions to ensure regulatory compliance and prevent costly fines or unexpected shutdowns.”

The CT5100 is a unique combination of advanced technology, high reliability, and rugged design. Its ‘laser chirp’ technique expands gas analysis in both the near- and mid-infrared range, enhancing process insight, improving overall gas analysis sensitivity and selectivity, removing cross interference, and reducing response time. The laser chirp technique produces sharp, well-defined peaks from high resolution spectroscopy that enable specificity of identified components with minimum interference and without filtration, reference cells, or chemometric manipulations.

“The CT5100 modular design and patented ability to chirp up to six lasers in one enclosure provides greatly expanded measurement capability as well as superior analyser availability and lower maintenance costs,” said Dave McMillen, North America business development manager. “Start-up and commissioning is quick and maintaining the analyser requires minimal technician time and material cost.”

Emerson Enardo relief valves get WirelessHART communications

Emerson acquired Enardo, a manufacturer of pressure and vacuum relief valves based in Tulsa, Oklahoma, in late 2013. This week saw the launch of a new wireless enabled version of the Enardo pressure and vacuum relief and safety valve used on storage tanks in the oil and gas, petrochemical and pharmaceutical industries.

Enardo_950_w-bracket

By adding the Smart Wireless monitoring system operating over the Emerson WirelessHART network, the safety valves, normally located on the top of large storage tanks, can easily signal to operators in the control room that they have been triggered to either relieve a pressure or vacuum condition. Such situations can arise as a result of changes in temperature, liquid level, or both, and relief valves are essential to prevent tank over or under-pressure conditions that could lead to structural failure. Enardo pipe-away, vent-to-atmosphere, in-line and end-of-line relief valves are typically installed on storage tanks to control evaporation and fugitive emission losses that result from flammable and hazardous petroleum vapour-producing products. Knowledge of the actuation of such a safety valve enables an immediate response, where needed, to prevent problems which can be related to safety, emissions, and the quality of a tank’s content.

Steve Attri, product manager at Emerson for the Enardo valves, commented: “Until now, PVRVs have remained un-monitored, with none of the feedback loops commonly seen in other pressure control devices. As the tank’s primary pressure control device, this wirelessly-monitored solution can be invaluable.”

Enardo manufactures tank and terminal safety equipment, including hatches, vent, pressure and vacuum relief valves and flame arrestors used in the oil and gas, petrochemical, chemical and other industries. Enardo in-line and stack vent valves have been the oilfield industry standard for more than 80 years.

Prior to the acquisition by Emerson, Enardo had sales of $65m a year, and employed 140 people. It now operates within the Regulator Technologies business, previously known as Fisher Regulators, within Emerson Process Management.

Emerson acquires Spectrex

Emerson Process Management has announced the acquisition of Spectrex Inc, a leading US-based manufacturer of flame and open path gas detectors. With this addition, Emerson will have the most comprehensive line of flame, gas and ultrasonic leak detector solutions used for safety monitoring in the industry.

Spectrex will join the Rosemount portfolio of measurement and analytical technologies, joining the capabilities already available with the gas leak detection systems acquired in Groveley Detection (nickdenbow.wordpress.com/2013/06/24/1345/) in June 2013.

For nearly 34 years, Spectrex has been the leader in flame and open path gas detection. It developed the world’s first ultraviolet-infrared (UV/IR) and triple infrared (IR3) flame detectors and was first to introduce xenon flash lamps in open path detector design, increasing detectors’ resilience to atmospheric conditions while reducing power consumption. These innovative advancements in safety monitoring provide a powerful solution for customers in the oil and gas, petrochemical, chemical and power industries.

“We are very excited about adding the Spectrex product line to our flame and gas detection portfolio,” said Tom Moser, group vice president of Emerson Process Management’s measurement and analytical technologies. “Emerson is committed to helping our customers protect their employees, facilities, and the environment, and we are now better positioned to serve that need.”

Spectrex and its staff are located in Cedar Grove, New Jersey, with sales and technical support offices in Houston, the United Kingdom and Taiwan.

Editor’s note: I tried to launch the UK sales of the first UV/IR detection system ever developed (so I was told at the time) which was made by Armtec in New Hampshire. That was in about 1983. Maybe Spectrex bought up Armtec? All inputs will be welcomed!

Emerson acquires Cascade Technologies

The acquisition is intended to expand Emerson’s gas analysis portfolio, adding laser-based measurement analysers and systems for enhanced industrial emissions monitoring, production efficiencies and regulatory compliance.

Emerson has announced that it has acquired Cascade Technologies Ltd, based in Stirling in Scotland, UK, a leading manufacturer of gas analysers and monitoring systems using their Quantum Cascade Laser (QCL) technology.

New Emerson fork viscosity meter

The direct insertion Micro Motion Fork Viscosity Meter is designed for demanding applications where accurate, fast-response viscosity and density monitoring is required.

Emerson Process Management has released the Micro Motion Fork Viscosity Meter, the next generation of the market-leading Micro Motion 7827 and 7829 direct insertion viscosity and density meters.  Incorporating the same rugged and reliable tuning fork design as its predecessors, the Fork Viscosity Meter is built to tackle demanding process applications such as oil fired heater combustion control, HFO blending/production and pump protection.

In applications where accurate, fast-response viscosity and density monitoring is required, this direct insertion meter is the ideal choice. It helps solve the problems customers face on a daily basis, such as reducing oil fired heater combustion emissions, minimising cutter-stock usage in HFO blending and reducing contamination risks on multi-product pipelines.

The Fork Viscosity Meter incorporates a hazardous area approved head-mounted transmitter that has the flexibility to connect to control systems via a wide range of digital and analogue protocols. Because it supports 4-20mA, HART, WirelessHART, Foundation fieldbus and RS485 Modbus, system integration and start-up /commissioning costs are significantly reduced.

An additional benefit of the Fork Viscosity Meter is the capability to accept and process external signals from other field instrumentation such as temperature, pressure and mass or volumetric flow devices.  The input of these external measurements enables the meter to calculate and output enhanced process measurements, minimising the need for extra cables and so reducing installation costs.

The Fork Viscosity Meter also incorporates a new diagnostic capability called ‘Known Density Verification’ that checks the meter for measurement alarm conditions, sensor integrity and the presence of coating, erosion or corrosion. This new technology expands the availability of diagnostics information in critical viscosity and density measurement applications which can result in significant maintenance costs and cycle time reductions.
