Emissions monitoring market to exceed $583m

Paul Boughton

The market for continuous emissions monitoring systems (CEMS) to measure pollutants discharged from stacks will rise to $583 million/yr in 2009.

The total monitoring market including ambient monitoring and stack testing will reach the $ billion level worldwide in 2009. These are the conclusions provided in Air Pollution Monitoring and Sampling World Markets, an online continuously updated market report provided by the McIlvaine Company.

The reason that the CEMS market in 2009 will be $137 million/yr higher than the $446 million in 2005 is due primarily to increased activity in coal-fired power generation. This includes the construction of many new coal-fired plants in China and the US.

But even strong advocates of greenhouse gas reduction such as the UK and Germany are also planning to build new coal-fired plants. So there will be a surge in new coal-fired generation across the world.

Another big factor is the retrofitting of NOx and SO2 control equipment at existing power plants in Eastern Europe, China, and the US. Each of these installations will require additional monitors to aid in process control.

While China and the US will be the biggest purchasers, many countries will also be retrofitting systems to remove NOx and SO2. In countries such as Chile where there are conversions back from natural gas to coal, the CEMS needs will be extensive.

The coal-fired boiler Mercury CEMS market will account for as much as 10 per cent of the total market over the next few years. Mercury control requirements for power plants in the U.S. will necessitate CEMS. In fact, with the trading value of mercury likely to exceed $40 000/lb, there will be the justification of redundant mercury CEMS.

The gas turbine CEMS market was bigger than any other in 2000. But this market has declined rapidly and is not expected to regain the lost ground.

The waste incineration CEMS market is slated to grow steadily. Because of the many pollutants which must be measured, CEMS can exceed $500 000 for a single incinerator. The waste-to-energy market is growing rapidly in Europe and Asia although it has not progressed in the US. However, the concept of biomass as renewable energy source could result in a policy change.

Mass particulate monitoring will experience double-digit growth worldwide.

Over the next five years more countries will turn to mass monitoring to replace the present opacity systems. Opacity monitors have long served to provide rough indications of particulate emissions. But with the tight limits now place on emitters, mass monitors provide the only solution for accurate measurement.

Governmental agencies will continue to be the largest purchasers of ambient monitoring systems. The trend is toward more automated and costly systems.

The reason is that the savings in labor required to retrieve and weigh periodic samples more than offsets the initial capital difference.

Stack testing remains a primarily local business. No stack testing company is truly international. However, within the US several companies have attained significant size by concentrating on the more difficult measurement tasks.
