The Chiyoda Corporation, Japan’s leading engineering and construction firm, has announced an agreement with Burmeister & Wain Energy A/S to license its flue gas desulfurization process technology for use at Asnaes Power Station, which is owned by major European energy provider, Denmark-based Dong Energy A/S.

The Asnaes coal-fired power station in Kalundborg is Denmark’s largest generating facility, with total capacity of 1,057MW. Under the agreement, Chiyoda will license the CT-121 process to BWE, and BWE will be responsible for engineering, procurement and construction (EPC).

In the European market, demand for flue gas desulfurization plants is expected to rise steadily, particularly in Eastern Europe, and Chiyoda expects to acquire more contracts due to the superiority of its CT-121 process technology. The CT-121 process already has a 22% share of the US market, where environmental regulations are becoming increasingly stringent.

The Chiyoda Corporation, headquartered in Yokohama, Japan, provides services in the field of engineering, procurement and construction for gas processing, refineries and other hydrocarbon or other industrial plant projects, on a global basis including the Middle East, Russia and South East Asian, Africa and Oceania regions.

Building on the contract award for the Asnaes Power Station, the company will increase its sales efforts in order to expand market share in Europe as well.

The Chiyoda Thoroughbred 121 (CT-121) flue gas desulfurization (FGD) process is a unique technology developed by Chiyoda in which sulphur dioxide (SO2) is absorbed from flue gas generated by coal-fired, oil-fired and other types of boilers and removed as gypsum.

Unlike conventional processes in which an SO2 absorber is sprayed on flue gas, the CT-121 process uses Chiyoda’s unique absorber, the Jet Bubbling Reactor (JBR), in which the flue gas is blown into water forming a fine bubble bed where SO2 is absorbed, oxidised by injected air, and then neutralized by ground limestone slurry.
