Rotork actuators are fulfilling the all-electric specification for valve control on new gas dehydration units constructed at seven sites in the Transylvanian region of Romania. The new plants have been built for Romgaz, the largest natural gas producer in Romania, responsible for the production of around 40% of the country’s consumption. Dehydration plants use triethylene glycol to remove the water from natural gas in order to prevent downstream processing problems such as freezing, corrosion and the formation of hydrates.
The specification for the new plants ruled out the use of air instruments and compressors, dictating the use of explosionproof electric actuators for isolating and control valve duties in the hazardous areas. This has been achieved with ATEX certified Rotork IQT isolating valve actuators and CVA control valve actuators. Both designs feature intrinsically safe, non-intrusive setting and configuration technologies, data logging for diagnostics and preventative maintenance planning, and double-sealed watertight environmental protection. The CVA offers a highly accurate and responsive method of automating control valves, without the complexity and cost of a pneumatic supply. With resolution figures better than 0.1% and the ability to eliminate position overshoot, the CVA helps to maximise product quality and plant capacity. DOWNLOAD VALVE SOLUTIONS APP.VISIT OUR WEBPAGE
