What technologies or strategies can be used to fix methane emissions?
As for measurement, there are several technology options to fix leaks and modify or replace equipment that deliberately vents gas to the atmosphere. Vapor recovery units (VRUs) capture vented gas for reinjection into the processing system. Instrument air systems substitute compressed air for pressurized natural gas, nearly eliminating emissions from pneumatic devices.
For pipelines and processing facilities, tried-and-tested low-emissions (Low-E) valves can reduce fugitive emissions by up to 96% when compared to non-Low-E valve products. Over the past several years, Schlumberger’s Cameron business has developed new sealing technologies to meet the most demanding applications and certified its existing valve designs to the API 624, API 641 and ISO 15848 standards, which are generally considered the gold standards for Low-E certification for valves. Today, more than 95% of the company’s valves are Low-E certified.
