New control valve positioner package
Control valve specialists Samson Controls have developed a control valve positioner package which ensures precise positioning with fast response times, over the entire operating range, for example strokes of 60 mm and greater. The package consists of a positioner and a special hook up of several volume boosters with different air output capacities that perform this task.
Closing and opening times of less than two seconds can be over the entire positioning range.
The flow control applications for which the Samson package has been successful is for compress or bypass valves (anti-surge valves) as well as in petrochemical applications involving adsorption processes in moving bed adsorbers.

When the tanks are full, the liquefied carbon dioxide will be loaded onto a dedicated carrier from Royal Wagenborg and shipped to the INEOS Nini platform in the Danish North Sea. From there, it will be safely injected via pipeline into subsurface reservoirs approximately 1800 m beneath the seabed for permanent storage.
