Commercial application of new type scrubber
- Mitsubishi Heavy Industries, Ltd., Yokohama (Japan); and others
A highly efficient and compact flue gas desulfurization scrubber called the Double Contact Flow Scrubber (DCFS) was developed and successfully applied commercially. The first DCFS unit started commercial operation for an oil-fired boiler since July `93 followed by the second unit for a coal-fired boiler since July `94 in Japan. High density liquid-particulate layer is formed in the scrubber by collision of the absorbent liquid sprayed from the special nozzles installed at the bottom of scrubber with the falling finely-sprayed liquid once spouted up. Due to the highly efficient liquid-gas contact at the liquid layer, high desulfurization and dedusting efficiency can be obtained with low power consumption. Utilizing the simple construction of this scrubber, a stack-integrated simplified compact FGD system was developed and is now being supplied to the Weifang Chemical Plant in China under the Japanese Government`s Green Aid Plan.
