Rotork in the Mongolian coal industry
21/11/2008
Valve actuation applications don’t get much more arduous than those experienced in the coal industry and when the end user’s plant is situated in the harsh environment of Inner Mongolia, the successful achievement of long term reliability becomes even more vital.
Photographed in the workshops of valve distributor Triflow Corporation, this Rotork GP range pneumatic actuator with manual hydraulic override is operating a 24 inch Class 2500 347 stainless steel Adams butterfly valve with hardened trim, protective seats and seals and purging. The valves are used on highly abrasive, ultra-high pressure applications in the Axens ‘T-Star’ coal liquefaction technology supplied to the Shenhua Group Corporation of China.
This is the first-of-a-kind direct coal liquefaction plant and will produce about 19,000 barrels per day of oil from coal in a single train plant at the Inner Mongolian site. Axens was selected due to the company’s extensive experience with heavy oil conversion and coal liquefaction, the ‘T-Star’ technology being the latest development in over forty years of commercial operations.
Many more Rotork GP range actuators – some in massive sizes – are installed at the site, operating Mogas metal seated ball valves in various sizes and specifications. Some of these valves also feature Class 2500 pressure ratings, 347 stainless steel construction and special seals.
