New Integration Service Makes Offers a One-Stop- Shop for Process Analyser Solution

Yokogawa Europe (the Netherlands) recently

announced the launch of a new service – ASI or Analyser System Integration. This makes Yokogawa a

true one-stop-shop for ASI at both green-field or brown-field projects of almost any size, thus helping project owners to simplify their supply chains as they need only deal with a single team for all analytical requirements.

The mature European process industry has many aging plants, with many requiring updates, renovation and modernization. The complex nature of these renovation projects requires the highest quality design and engineering at all stages of implementation. At the same time, project managers need to simplify the procurement process to help manage risk and ensure that there is clear ownership of each part of the project.

Loek van Eijck, business unit manager, analytical solutions at Yokogawa Europe, said: “We’re very pleased to announce the introduction of Yokogawa Europe’s Analyser System Integration service. This services responds to a growing market demand within the chemical, oil & gas industry, and increasingly in other process industries, to simplify project management of both new installations and renovations. We’ll be working with our own analysers and those of 3rd-party manufacturers, but it makes sense for project owners and primary contractors to deal with a single integrator of analytical systems, and for that integrator to be a supplier of instruments being installed.”

One of the major issues facing project managers is finding a team with the right skills and experience for specialist areas of project implementation. Yokogawa’s ASI service guarantees access to design and implementation engineers with the highest levels of qualification and certification. The highly skilled project management team is fully certified by Project Management Professional (PMP), while the engineering team designs solutions to the explosion-proof standards specified by ATEX, IECEx and all other relevant standards bodies, making design compliance easier to prove. They are backed up by a professional execution team with more than 150 years of accumulated installation experience.

Yokogawa has built a global reputation for quality and innovation, and has now applied this to its ASI service. “We believe this sets our service apart from the competition,” said van Eijck. “Yokogawa has earned its reputation through involvement in some of the industry’s largest and most innovative projects, and is now able to apply this in Europe to ASI projects of almost any size from any process industry requiring highly accurate analytical instrumentation by sharing know-how with other ASI facilities and developing synergy among Yokogawa Group Companies.”

The service provides a full analytical services life cycle from design, fabrication and manufacturing to installation, on-site services and training. Yokogawa ASI also links up to the similar services provided by Yokogawa in its Asian and US divisions providing customers with global coverage – an obvious advantage for international organisations and projects.

The ASI service is based in Madrid, Spain. Almudena Mier, ASI location manager at Yokogawa, said; “We have created an excellent facility here for the new service which offers a great environment for the team and the projects they will work on. Madrid is well served by transport links to the rest of Europe and beyond, and has access to some great local engineering talent as well as being an attractive place to work for staff and customers who come from elsewhere in Europe.”

Yokogawa Europe’s new ASI service is set to provide a simplified supply chain for the analyser needs of major process engineering projects, ensuring quality of design and implementation, together with reduced project risk and cost, all backed by Yokogawa’s enviable reputation for quality.

General-Purpose Power-Quality Monitor for On-Site Testing and Troubleshooting

The Yokogawa (the Netherlands) CW500 power quality monitor, a general-purpose unit for field and on-site testing and troubleshooting, is the latest addition to the company’s range of power measuring instruments.

Featuring a range of clamp-on current probes, built-in data logging and measurements conforming to the IEC 6100-4-30 Class S standard, the CW500 is a multi-function instrument designed to aid the inspection and maintenance of power quality in factories, commercial or public facilities. In particular, it will detect, measure and record events such as voltage swells, sags, dips or interruptions, inrush currents, harmonics distortion and flicker which can have an adverse effect on equipment operation or energy efficiency.

The 4-channel instrument can measure multiple power lines in configurations from single-phase/2-wire up to 3-phase/4-wire, and will simultaneously measure AC voltage input on three channels, current input on four channels and DC voltage input on two channels. Parameters measured include the instantaneous, average and maximum/minimum values of voltage, current, DC input voltage, power, power factor and phase angle, along with phase advanced capacitance calculation.

All measurements are displayed on the built-in colour display screen in list, waveform, or trend formats with direct keypad control. The integration values of active, reactive and apparent energy are each displayed by consumption and generation, and demand power value can be monitored continually via graphical screens of power consumption compared to the targeted demand power value. Intermittent anomalies such as voltage swell, voltage dip, voltage interruption, transient overvoltage and inrush current are each recorded as events and marked on occurrence waveforms, with the type of fault listed for each event. Ongoing or continuous faults such as harmonics, flicker and voltage or current imbalance rates are recorded with waveforms displayed as required.

The CW500 operates over an input AC voltage range from 6 to 1000 V and a DC voltage range from 100 mV to 10 V. The current ranges are from 2 A (for leakage current only) to 3000 A, with intermediate ranges of 50A, 100A, 200A, 500A and 1000A depending on which dedicated clamp-on current probe is used. Accuracy for power measurements is 0.3% of reading. Up to 2 Gbyte of memory is provided by an SD memory card, and communication is via a USB interface which allows real-time management of measurements. Built-in PC software (CW500 Viewer) provides analysis of recorded data and report generation including automatic graph creation, as well as simple management of the main unit settings. The CW500 is a compact and lightweight instrument measuring 175 × 120 × 68 mm and weighing 900 g with batteries. Power can be supplied via AC mains or by six LR6 batteries.

Mass Flow Control for New Physical Vapour Deposition Applications

You know one problem with anodising and bluing? While it prevents corrosion, it can scratch off. Most anodising doesn’t strengthen a surface much. Chrome plating has been an alternative, but chrome-6 is toxic, and can still wear, pit and spall. Duralar, a vacuum deposition system manufacturer, wanted to develop a fast, diamond-like coating process using physical vapour deposition that’s harder and more durable than either. It would have applications in prevention of corrosion, erosion and wear on metal parts.

Duralar started with a generic vacuum deposition system, but none of the six built-in thermal controllers were calibrated for their special gas, tetramethylsilane (TMS), a vapourised liquid. The fact is, those controllers couldn’t change gases accurately, without downtime for a recalibration. So Duralar called Alicat (USA). Although TMS isn’t on Alicat’s standard list, with a bit of engineering they provided Duralar with a corrosion resistant flow controller with a custom gas calibration for TMS.

They retrofitted their system using the Alicat controller—it’s a drop-in replacement—and they are now assured that the accuracy of their TMS flow will remain high, whether flowing full scale or turned down to 0.5% of full scale. That’s because Alicat’s gas selection isn’t just a k-factor offset for a single point, it’s a complete performance curve based on NIST’s viscosity tables. Going forward, Duralar needn’t worry about inaccuracy due to changing temperatures or pressures in their factory, since the closed-loop sensor in the controller compensates for volumetric changes—unlike those original thermal controllers.

Next, Duralar wanted to develop a process to deposit this thin coating inside tubes and pipes. With the inside of the pipe coated, you could reduce abrasive wear and corrosion—perfect for flowing abrasive liquids in a pipe, or protecting the inside of a rifle barrel from rust. The technique is clever: seal the ends of the tubes, and the interior of the tube becomes the vacuum chamber. The catch is, you need to be able to vary the location of the plasma-producing electrical discharge inside a narrow tube to get a complete coating. So, more prototyping, more experimentation, and Alicat to the rescue again.

By using an MCS flow controller for the corrosive TMS and just two more Alicat MC mass flow controllers, they were able to change gases at will, selecting from up to 98 built-in types and 20 user-customisable mixes—even more on the corrosion-resistant controller.

Then, they used Alicat’s downloadable LabVIEW drivers to build the vacuum process steps, controlling the MFCs and their shut-off solenoids from a remote laptop. In due time, they had perfected the process and begun building coating systems to order. Now, you can order diamond-like coatings for your metal parts—or the systems to provide the service for others—and the vacuum coating is more durable than anodising , while quicker and harder than chrome plating. Thanks to Alicat’s flow controller adaptability, physical vapour deposition gets better and better.
