When Intertek, a leading provider of safety testing solutions, needed to replace their decommissioned Servomex 1100 unit for their Global Explosive Atmosphere Testing Services based in Chester, UK, Servomex recommended the SERVOFLEX Micro i.s (5100 i.s): a single component, Intrinsically Safe portable gas analyser able to deliver flexible, reliable and accurate measurement in hazardous conditions.

An ATEX Notified Body for product testing, assessment, inspection and certification for all category 1 and 2 equipment, and offering a range of services including EX testing and certification CE, IECEx Testing and Certification (International) and Quality Management Systems, Intertek required a portable that could be moved and applied to a variety of test scenarios. By being built to a rugged, robust IP65 construction and optimised for portable use with an intuitive interface, user-configurable audible alarms and maximum memory storage of 200 measurements, the Micro i.s was therefore ideal for Intertek’s precise testing requirements.

Accuracy, stability and  reliability is guaranteed using Servomex’s world-leading paramagnetic transducer technology – which offers selective measurement of oxygen without the disadvantages of electrochemical or zirconia cells – and single beam, single wavelength infrared technology to measure percent levels of oxygen and carbon dioxide respectively.

The Micro i.s is now used by Intertek to monitor and mix various explosive gas mixtures, introduced into a sample to test for propagation to the external atmosphere and to measure the internal explosive pressure generated.  As the analyser is designed to monitor predominately explosive gases in air, the mix is adjusted by Intertek engineers and calculated using oxygen depletion as the gas is introduced. The Micro is also being used for testing purged cabinet processes, with the analyser set to measure oxygen levels within an enclosure as it is purged with gases such as nitrogen.

“We have been delighted by the performance of the Micro i.s in all the safety testing processes where it is required,” says Ian Clark, Approvals Engineer, Intertek.
“In terms of accuracy and reliability, as well as the practical considerations of portability, it delivers exactly what we need to the stringent standards we demand when we carry out our crucial safety tests.” 

True portability for the Micro is ensured by the fitting of a carrying strap and optional soft carry case, while the flexibility of the unit is increased with options for a sample probe and pumped or non-pumped (AFCD) options – the pumped version benefiting from an optional sample conditioning kit if required. This ensures the Micro is ideal for applications where hazardous area combustion optimisation exists, including natural gas processing, catalytic cracker regeneration, Hyco applications, process monitoring and inerting applications.

Four SERVOTOUGH Oxy analysers will replace the existing analysers in a revamping project at the Shanghai-based 200kt/a phenol/acetone plant, which has been in operation since 2004. The Oxy units will monitor for residual 02 levels in the off gases of the oxidation reactor, a crucial measurement in the refining process that requires high levels of accuracy and reliability to ensure critical safety levels are maintained.

Servomex was chosen to supply the SERVOTOUGH Oxy on the basis of Servomex’s world-leading Paramagnetic oxygen cell technology, which offers industry-leading levels of linearity, accuracy and reliability, as well as the Oxy’s advanced functionality and safety concepts which secured it a prestigious Gold Award at this year’s global Golden Gas Awards. Servomex was also able to demonstrate excellence in delivering ongoing service and support, which will be managed by Servomex’s Asia Pacific business centre, based also in Shanghai.

Offering an exceptional range of industry-standard options and innovating no less than three unique functions, the Oxy replaces the acclaimed Servomex 1900 to set new standards of performance from a single, cost-effective unit. The Oxy can be configured for a range of applications including process control, safety critical oxidation, flare stack analysis, product purity, feedstock clean-up and inerting/ blanketing.

“We are pleased to have been selected to supply the SERVOTOUGH Oxy to such an important client in China,” said Chris Cottrell.
“Servomex has been delighted with the excited global reception given to the new Oxy, so we will be following the progress and performance of these units at Sinopec Shanghai Gaoqiao very closely.”

Chematur Engineering AB of Sweden has selected Servomex and channel partner OmniProcess AB to supply these critical instruments to the new 50,000 MTA capacity plant being built on behalf of Indian chemical manufacturer GNFC.

The new system will help control the process and monitor the quality of output in the manufacturer of TDI, a key isocyanate used in the manufacture of polyurethane and used for a variety of applications including flexible foams used in furnishings and the motor industry.
Servomex will supply a range of its world-leading gas analysers to fulfill the complex requirements of TDI monitoring, including 15 SERVOTOUGH SpectraExact (2500) process gas analysers, two SERVOPRO 4210 gas purity analysers, one SERVOTOUGH OxyExact (2200) paramagnetic oxygen analyser and three k1550 katharometer-based analysers.

Designed, manufactured and tested in configurations specific to the required measurement and background stream, the SERVOTOUGH SpectraExact is a photometric process analyser that offer single or dual component gas analysis to suit virtually any process, combustion or emissions gas analysis application, making it ideal for several TDI measurement processes including monitoring the off-gases from mixing chlorine with carbon monoxide to make phosgene and monitoring for both carbon monoxide and chlorine in phosgene.

Control of residual O2 concentration in pure CO in the range 0% - 0.5% will be made by the  SERVOTOUGH OxyExact 2200, with a measurement precision made possible by Servomex’s renowned paramagnetic cell technology that enables an oxygen measurement that is totally unaffected by other gases in the monitor stream. The SERVOPRO 4210 gas purity analysers will monitor the level of specific impurities in pure H2 and pure CO respectively, with one unit monitoring a pure hydrogen stream for trace carbon monoxide and other 4210-based system monitoring for the presence of methane in CO. Finally three k1550 katharometer analysers will monitor the hydrogen purity and the quality of CO supply to the TDI process by checking the level of residual H2 remains between 0 and 1%.

Each Servomex gas analyser will be installed in its own cubicle with an appropriate sampling system and all necessary pipework, ready for connection in the appropriate area of the plant.
 
In addition to Servomex’s world-leading experience in offering reliable and accurate process analysers suitable for different and tough applications, Chematur selected Servomex on proven experience in the design and build of TDI analyser systems, as well as the ability to provide industry-best levels of service and support to the project.

“TDI production is by its nature a complex process, so Servomex is delighted to have been selected once again by Chematur to supply this gas analyser system through OmniProcess AB,” says Chris Cottrell, Managing Director, Servomex.
“We have been chosen not simply on the acknowledged quality of our instruments, but in our ability to deliver a complete gas analysis solution that ranges from the design and build of the system to providing ‘local-for-local’ service and support in India.”

The TDI plant is scheduled for completion in September 2010.
