Dr. Ing. Horst Grochowski, inventor and entrepreneur, was the first in the world to develop and patent a dry exhaust gas purification method for counter-current operation at the end of the 1980s. Thanks to hard work, continual development and an eye for detail, the technology reached beyond Germany's and ultimately Europe's borders. The systems have been constructed in Japan since the mid 1990s, with the technology subsequently reaching mainland China via Taiwan and Korea. The technology is currently contributing to the "Blue Sky" campaign. Dr Grochowski and his team of experienced engineers still know how to closely collaborate with licensees such as Babcock, Ude, Mitsui, Hyundai, Samsung-Corning, Ansteel, BaoWu-Steel, etc. The fact that WKV technology (CSCR®) has ultimately firmly established itself in China is thanks to a trust-based and targeted interaction licensees and end customers and clear technical leadership.
