In the 11th plan from 2006-2010 the six major Chinese utilities will install 300 new SO2 flue gas desulfurization (FGD) systems. Each of these projects is identified in the Utility Environmental Upgrade Tracking System published by the McIlvaine Company.
To put this in perspective, the
The Chinese will surpass the
Contrary to reports that scrubbers are planned but
not built, units are being commissioned at a high rate. McIlvaine is
reporting the start dates and also reports when the systems pass the guarantee
tests. To date most of the systems have been built under license from
offshore suppliers. Major licensors include Babcock & Wilcox, Alstom,
Marsulex, Austrian Energy, Lurgi Lentjes, Fisia Babock,
There are a number of FGD projects being installed
in other countries, but no one country has a huge number.
The curtailment of natural gas is creating FGD
projects in unexpected places.
Many of the FGD systems in
Most of the FGD systems now planned or under construction utilize limestone which contacts the gas as wet slurry. In approximately 15 percent of the projects lime is injected in fluidized beds or through spray drying.
McIlvaine’s weekly Alert provides the latest developments. A user friendly database identifies hundreds of parameters on every project. The database also identifies particulate and NOx control projects.
