June 2015 - FGD and DeNOx Insights 51

The McIlvaine Company has a number of initiatives to create high level discussions among end users and suppliers. The purpose is to enhance the decision making process. McIlvaine participated in a global sourcing panel discussion at the Industrial Valve Summit in Italy last month. The major oil companies and consultants all referenced the loss of experienced personnel and the need to rectify this continuing loss of knowledge.

The panelists included some of the most knowledgeable valve experts who make or influence decisions on many projects around the globe.

0.00 Round Table: Global sourcing in the changing energy industry
Room: Caravaggio

Jean-Michel Rivereau,
Head of the Piping, Valves and Vessels Department, Technology Division, Total E&P

This live discussion in Italy was followed two weeks later by a recorded webinar on power plant valves with various problems resulting from fast cycling of gas turbine HRSGS and the next week with a discussion of the whole wet limestone FGD system options. Three valve suppliers debated butterfly vs. knife gate valves for slurry control.

McIlvaine webinars in the past have been two thirds presentations and one third discussions. However beginning two months ago the webinars are 80% discussion and only 20% presentations. The visual background each discussion is a decision guide with as many as 90 power point displays. As the discussion progresses the relevant information is displayed.

The big push to retrofit flue gas desulfurization (FGD) systems on all the coal-fired boilers in the U.S., Western Europe, Japan, Taiwan and Korea is now over. The market in China has peaked but remains strong. Other countries in Asia and Africa are now addressing their SO₂ emission problems. McIlvaine, in its FGD Market and Strategies therefore, predicts:

· A multibillion dollar annual market for new systems with the bulk being purchased in Asia.

· An equally large market to upgrade and replace systems in developed countries.

India has now committed to several wet limestone FGD systems. Indonesia, Vietnam and other Asian countries are increasingly installing SO₂ capture systems with new coal-fired boilers. China continues to build power plants with FGD. It has also committed to upgrade more than 100 plants where the SO₂ removal efficiency was low.

There are some potential technology developments which could expand the investment in new coal-fired power plants but change the type of FGD chosen.

· One development is the catalytic filter. When combined with direct sorbent injection it allows NO_x, particulate and SO₂ to all be captured in one device.

· Another development is two-stage scrubbing in which HCl and flyash are captured in a venturi scrubber and SO₂ is captured in a second absorber. The first-stage slurry is recycled and a 30 percent dirty hydrochloric acid stream is bled to a rare earths processing plant. Both salable hydrochloric acid and valuable rare earths are the resultant products.
