Rotork in Australia valves are high-quality valves and have been selected for different applications in Australia throughout the liquefied natural gas industry. Nowadays, the company has received numerous orders for more than five thousand valve actuators, electro-hydraulic, embracing electric, gas-over-oil and pneumatic technologies.
The three projects
The three projects comprise of Australia Pacific LNG, the Santos GLNG and Queensland Curtis LNG. The projects are working on coal seam gas in Bowen and Queensland’s basins. A lot of kilometres of pipelines are designed to link the wells that produce natural gas on the mainland of Queensland with the world-class plant of LNG production under construction on the island of Curtis. This will initially produce over 27 million tonnes of LNG to be exported every year. The coal seam gas projects are based on an efficient and clean source of energy with half the emission of carbon dioxide that coal emits.
Upstream mainland wellheads
It is a requirement that Rotork valves in Australia to be produced and distributed to a total of two thousand widely distributed sites. Apart from the natural gas, the actuators will control the flow on the process of coal seam water extraction. The resources are required to be treated for use by industrial and agricultural customers and supplementing domestic water supplies.
The function of the CVA actuators
The actuators are required to deliver a repeatable and continuous modulating control that will have a programmable fail for positioning option.
Repeatability, resolution and hysteresis performance has been quoted to be less than 0.1% of the full scale. This offers suitability for the most demanding control Rotork Australia valve application. The innovative CVA actuation will also remove the expenses of installation and maintenance of instrument air supplies at the remote sites where the gas’ pressure is too low to provide a viable actuator operation source.
