Six major Chinese utilities will install 300 new SO2 flue gas desulphurisation (FGD) systems before 2010, says a new report from the McIlvaine Company.

Currently, the US is the leading constructor of scrubber systems, but only 222 systems were installed on utility units between 1968 and 2004. This means that even though new scrubbers will be mandated, the US will not be able to maintain its position as number one producer of FGD plants and China will surpass the US coal-fired utility capacity between 2010-2012.

Germany is third, with 100 FGD units and more under construction, while there are a number of FGD projects being installed in other countries, including India, Japan, South Korea, Taiwan and Chile..

Most of the FGD systems now planned or under construction will utilize limestone which contacts the gas as wet slurry, McIlvaine says. In approximately 15% of the projects lime is injected in fluidized beds or through spray drying.

Suppliers of wastewater treatment systems in the US are experiencing rising demand for their products as some 300 US wastewater treatment systems are adding new plants, expanding existing plants, or revising these plants to meet new effluent or odour control standards, says McIlvaine’s US municipal wastewater treatment facilities and people database.According to the company, the largest numbers of expansions are in the large states with relatively fast growth, such as Arizona, Texas, California, Colorado, and Florida.

Most of these new plants and expansions are due to odour control, beneficial sludge reuse, and improvement in effluent quality, while in arid states, wastewater reclamation and reuse is the basis for new investment.

Broadbent to supply more decanters for Chinese chemical processingUK centrifuge specialist, Thomas Broadbent Ltd is continuing to supply large-scale decanters to Chinese and other Far Eastern producers of Pure Terephthalic Acid (PTA) – an oil-based chemical used in the production of polyester fibres.

As demand for man-made fibres continues to increase at record levels, international textile and

PTA producers are currently upgrading and expanding production facilities with new and more cost-effective technologies, particularly in areas such as China, India, Taiwan and Thailand, the company says.

The company recently supplied PTA decanters to the Zhejiang Yisheng Petroleum Co Ltd in

Ningbo, China for use in its first stream production process. Due to their high capacity, robust construction and durability, Broadbent decanters are highly suitable for PTA dewatering applications and particularly compatible with the production process, the company claims.

Ahlstrom to invest �27 million in UK nonwovens Ahlstrom plans to invest approximately �27 million in a new food nonwovens production line at its plant in Chirnside, Scotland. The new line utilizing spunmelt technology will primarily serve the growing infusion products market with next generation spunmelt products.

The infusion products market in general is anticipated to grow

at 5% annually, Ahlstrom says. The growth in high value-added segments, which is higher than in traditional tea markets, demands a differentiation in the type of filter media used.

“There is a clear market demand for new spunmelt materials,” said Claudio Ermondi, senior vice president, nonwovens.

Ahlstrom currently operates a nonwovens plant in Chirnside on the Scottish borders with three production lines and is an established player in the infusion market. The new investment consists of a building and machinery, and is estimated to be operational in late 2008.
