ABB to unveil its latest emissions technologies at AQE 2015

March 6, 2015

We are delighted to reveal that ABB will be exhibiting its latest range of air and gas analysers at the Air Quality and Emissions (AQE) Show at the Telford International Centre (22nd – 23rd April 2015). Stands 70 and 71 will feature a comprehensive selection of ABB equipment including laser, zirconia and FTIR spectrometry.

Taking centre stage will be ABB’s new ACF5000 hot/wet extractive continuous emissions monitoring system for combustion applications.

Using FTIR technology, the ACF5000 enables simultaneous analysis of up to 15 different gas components including SO2, CO2, CO, NH3 and VOCs using a single sample probe system.

Completely self-contained, the ACF5000 offers a turnkey solution for combustion process monitoring in municipal and hazardous waste incineration and power plants using coal, oil or waste.

The system is also currently undergoing MCERTS certification for use in process plants for applications including DeNOx and DeSOx plant optimization and HCL scrubber monitoring.

Other products on show will include the stand-alone LS4000 laser gas analyser system for use in hazardous locations. Enabling in-situ monitoring of stacks, pipes, process chambers and other similar applications, the LS4000 uses tunable diode laser absorption spectroscopy (TDLAS) to provide direct measurement of hazardous gas streams. Offering a very fast response time, the LS4000 is especially suited to high pressure, high temperature applications with fast changing conditions.

Other equipment on display will be ABB’s Endura AZ20 zirconia oxygen and StackFlowMaster instruments. The AZ20 is a compact combustion gas analyser for high temperature applications up to 800°C. Manufactured using a new ceramic-to-steel bonding process, the AZ20 offers improved resistance to thermal stresses and shocks compared to a conventional brazed design. This enables it to be used in a wider range of applications subject to sudden variations in process temperatures, as well as offering a gas tight bond throughout its operating temperature range.

The StackFlowMaster is an in-situ device for measuring flows in stacks up to eight metres in diameter. The StackFlowMaster manual version is for use in applications with relatively clean gases such as gas fired combustion processes. The StackFlowMaster automatic version features a purging and auto/span zero capability, making it suitable for applications with dust-laden gas streams.

Joining these products will be examples from ABB’s EasyLine EL3000 range of photometers for gas analysis. Based on ABB’s MCERTS-approved extractive continuous gas analysis technology, the EL range is available in both infrared (IR) and ultra-violet (UV) photometers, with a choice of sensing and analyser options including electrochemical, paramagnetic, thermal conductivity and trace oxygen.

ABB will also be hosting a workshop covering key issues affecting the deployment of gas analysers in industrial applications. The workshop, hosted by our very own Analytical Product Manager, Günter Haberzettl, will explain how implementing a QAL3 evaluation tool into a continuous emissions monitoring system can help simplify data storage and reporting, with users able to access data via a web browser (12.00 12.30pm, April 22nd, room 2; 12:00 – 12:30pm April 23rd, room 4).

ABB achieves MCERTS for pH measurement

March 14, 2014

We are delighted to have achieved MCERTS certification for our AX400 pH measurement system, which forms part of our commitment to providing users with the best available techniques for their environmental monitoring requirements.

Tested in a field trial conducted over a period of 9 months on an effluent discharge at Pembroke Power Station, the AX400, coupled with our 7650, 7651, 7660 pH sensors, successfully demonstrated its suitability for use in treated wastewater, untreated wastewater and receiving water applications.

The achievement of MCERTS certification means that our AX400 pH measurement systems can be used in applications such as the power industry and potable water treatment.

The measurement of pH and Redox (ORP) in high purity water applications in power plants requires a number of essential elements to achieve accurate and stable readings. These include a stainless steel flowcell to minimize static effects and a reservoir-fed reference junction that overcomes KCI depletion and blockage to ensure a stable junction potential and simple reference junction replacement for low-cost maintenance.

The 7660 system has been proven to meet all these requirements by providing accurate measurement in samples below 20 μS/cm. This is especially ideal in boiler chemistry control applications, which require close control of pH levels. For applications up to 100 μS/cm the 7651 with polypropylene flowcell and the 7653 with a reservoir-fed reference electrode option provide an economical option.

For potable water treatment applications, accurate and stable pH measurement is required for optimum control at the coagulation stage of the process to minimize coagulation costs and treated water quality.

Measuring pH in coagulation processes can be particularly difficult, due to the high level of suspended solids and significant precipitation that can block the reference junction.

To overcome this problem, an ideal pH system should include an optional flowing reference junction that overcomes KCI depletion and blockage. Other features should also include simple reference junction replacement to enable low-cost maintenance in samples that contain high levels of particulates, and the availability of a low resistance glass electrode option to provide fast response in low temperature applications.

The 7600 Series meets all these requirements. The 7651, with polypropylene flowcell and the 7653, with a reservoir-fed reference electrode are an ideal low-cost option that can be readily replaced and installed. Both systems are highly-suited throughout the potable water treatment process.
