Servomex launches innovative new TCD measurements for MultiExact and MonoExactCrowborough, UK, 30 October 2012 - Following the successful launch of Servomex’s revolutionary TruRef Thermo-Conductivity Detector (TCD) technology, Servomex is extending its TCD sensor range with new measurements for helium (He) and hydrogen (H2) in the SERVOPRO MonoExact analyser and He in the SERVOPRO MultiExact multigas analyser read more...
The world’s first true TCD gas measurement, which for the first time makes a genuinely accurate thermal conductivity measurement of a gas, TruRef technology co-locates the reference and measure elements under isothermal conditions in the sample gas to eliminate the effects of changing sample conditions such as pressure and flow.
Fully enabled by the advanced performance capabilities of the SERVOPRO MonoExact and SERVOPRO MultiExact Servomex, TruRef technology already offers class leading measurements for argon (Ar) and nitrogen (N2) analysis. The new measurements deliver unrivalled TCD performance standards for H2 and He, particularly in terms of measurement accuracy, repeatability and drift - making them ideal for use in product purity and process control applications.
Measurements for He in N2 and He in O2 are available in measurement ranges from 0-2% to 0-100%, delivering a comprehensive analyser solution for He production processes and gas blending. A measurement for 0-20% H2 in Ar enables a new level of performance for hydro-argon applications in ASU production, where monitoring the H2 excess determines the conversion efficiency in removing O2 from Argon product after the air separation process.
Finally an H2 in N2 measurement will be available in ranges between 0-1% to 0-100%, enabling more efficient and accurate performance for a range of applications including H2 production, monitoring of H2 coolant in turbine generators and in the production of iron and steel.
“Servomex’s development of TruRef technology has raised the industry standard by improving the accuracy and stability of the gas measurement and reducing ownership costs to the customer,” says Charles Segar, Product Business Manager. “These exciting new TCD measurements further extends Servomex’s leading position in industrial gas analysis by taking the company into new markets and applications.”
The launch of the new TCD measurements makes the SERVOPRO MonoExact and MultiExact even more effective as value-adding gas analysis solutions for a range of industries and applications. In addition to utilising a range of Servomex’s sensing technologies, the MonoExact and MultiExact offer advanced features and options that include concentration alarms, auto-validation and auto-calibration, digital communications (Profibus, Modbus or Ethernet), integrated valve block, flow alarm and flow-meters.

Servomex installs innovative TDLS system for Shell Netherlands Chemie B.V.Crowborough, 18 September 2012 - Servomex, a leading manufacturer of gas analysis solutions, has installed an innovative solution for combustion analysis on ethylene cracker furnaces installed at Shell Netherlands Chemie B.V. read more...
Coinciding with a furnace refurbishment programme, the new flue gas analysis solution enables optimisation of the combustion control process leading to improved fuel efficiency and reduced carbon monoxide (CO).
SERVOTOUGH LaserSP 2900 cross-stack analysers were installed across the 13-meter radiant sections of the ethylene cracker furnace to monitor both Oxygen (O2) and Carbon Monoxide (CO) within the flue gas. The LaserSP employs the Tuneable Diode Laser Spectroscopy (TDLS) technique to make a path averaged measurement of the process gas concentrations close to the burners, enabling rapid process optimisation.
To protect the analyser optics it is common practise to flow purge gas over the windows of TDLS in-situ analysers, which are exposed to the hot process gas stream. In flue gas measurements, it has been necessary to employ dry N2 as the window purge gas, as opposed to instrument air, because ambient O2 is sufficiently high to interfere with the O2 process measurement. However, in partnership with Shell Moerdijk, the infra-red scan range of the LaserSP was extended to include additional absorption lines which only appear at elevated temperatures, greater than 600°C. By using one of these “hot lines” to monitor the process O2, it is possible to use instrument air as the window purge gas, as the O2 in the instrument air, being colder than the 600°C, is no longer “seen” at the process monitoring “hot” wavelength. The standard “cold” O2 absorption line was also monitored and this signal is utilised for the purposes of checking the LaserSP’s response to a test gas, and to provide an alarm in the event of an interruption of the flow of window purge gas.
Over a long process path measurement (in this case 13 meters), thermally induced flexing of the furnace walls to which the analyser is mounted can result in the laser “spot” at the receiver end of the analyser to move. With the usual parallel laser beam this would have led to a measurement failure when the laser spot moved out of the field of view of the receiver unit. This was overcome by adjusting the laser transmitter optics to diverge the beam such that the laser “spot” diameter was three times the diameter of the optical receiver lens. In this way the transmission of the laser beam to the receiver remains unaffected by thermal movements of the process. This “receiver overfilling” technique is only made possible as a result of the LaserSP’s second harmonic (2f) wavelength modulated signal (WMS) processing, which operates at a 200kHz carrier signal frequency, almost eliminating signal noise.
With two LaserSP analysers installed in-situ on each ethylene furnace for the measurement of 0-10% O2 and 0-1000ppm CO respectively, the combined solution is helping Shell Netherlands Chemie B.V. optimise process efficiency by reducing fuel consumption and process emissions, as well as reducing installation and operational costs.
