Overview
Electric actuators provide pressure regulation on natural gas distribution networks in the USA, automating the process and reducing emissions.
Challenge
Natural gas distribution networks have a significant number of pressure reducing stations which regulate downstream gas pressure for delivery to domestic consumers.
Solution
These stations can be a hot spot for methane emissions. These systems use pipeline gas as the motive power, and when adjustments are made, methane is vented to the atmosphere. An engineer must also travel to site to manually change a set point, resulting in emissions through their transport. The customer needed a solution that would eliminate these fugitive emissions and automate the pressure adjustment process.
Result
Fitting a PAX electric actuator directly to a regulator (to create a motorised regulator assembly) allows for remote operation of the set point. The system reduces emissions (the PAX uses electricity for power, not the pipeline gas); there is no constant bleed or venting of gas. No product is wasted.
Customer Benefits
When a PAX electric actuator is fitted, the set point can be operated automatically. There is no constant bleed or controlled leak from the motorised regulator assembly. The customer also benefits from position feedback, built-in alarms and limit switches, and fail-freeze capacity.

The importance of effective maintenance in LNG
In recent years, Liquefied Natural Gas (LNG) has emerged as a crucial component of the global energy mix, with LNG exports experiencing exponential growth.
How automation in upstream oil and gas processes can help reduce methane emissions
Methane is a powerful greenhouse gas that traps heat in the atmosphere. It is the second most abundant human-made greenhouse gas, after carbon dioxide (CO2), and is more than 28 times as potent at trapping heat in the atmosphere over a 100-year period(1).
Rotork adds new features to the intelligent IQ3 Pro range
Rotork is excited to announce that new features have been added to the industry-leading IQ3 Pro range of intelligent actuators. The new features include increased speeds for the IQT3F Pro electric modulating actuators, independent open/close speeds for part-turn actuators and closed-loop control for the multi-turn and part-turn actuators.

The value of effective flow control for the LNG industry
The amount of liquefied natural gas (LNG) in the world's energy mix is rising. The export of LNG has increased dramatically in recent years, with the USA alone expected to double shipments to Europe by 2022.1
How electrification can help reduce methane emissions
Sustainability within energy production is increasingly important in a world that faces a climate crisis. Reducing methane emissions during the production phase of oil and gas is the quickest way to address global warming, and electric actuation is a reliable, cost-effective, and efficient solution operators can adopt to meet methane emissions reduction goals.
