Oil and gas operations rely on durable components to keep their systems running and maintain a safe environment for workers and the local community. Sour gas wellbores contain dangerous liquids that, if not properly managed, can pose workplace hazards and local health and safety risks.
Manifold valves are among the many components used in sour gas operations to contain and manage fluids entering and leaving well reservoirs. Keep reading to learn more about how instrument manifolds can be used in sour gas environments, and where to find the best quality components from Hy-Lok Canada!
What Are the Benefits of a Manifold Valve?
A Manifold valve is designed to control and isolate the flow of liquids and gases using a block-and-bleed method.
This component acts as the middleman between instruments and process lines, and covers three key functions: isolating liquid pathways, equalizing, and venting liquid waste or excess during processing and maintenance.
Manifolds are essential to pressurized hydraulic and piping systems where liquids need to flow from one reservoir to another without disruption.
They prevent gas, vapours, and other dangerous emissions from leaking out of the system. This protects the environment and atmosphere from fugitive hydrocarbons.
Manifolds are available in several materials, including NACE MRO175 alloy steel, which enables wellsites to use them in corrosive environments, such as sour gas wells.
Why Use a Manifold Valve in a Sour Gas Well
“Sour gas” refers to substances with a high concentration of acid, such as hydrogen sulphide and carbon dioxide, which are highly corrosive.
Wellsites are required to use specialized equipment and components during well testing, zone isolation, well abandonment, and other tasks where tools and parts are in direct contact with the sour gas.
If sulphuric gas enters the environment, it can cause a variety of health concerns, including eye irritation, headaches, nausea, disorientation, and respiratory distress. In more severe cases, well control failure can expose workers to fatal doses of H2S gas.
The danger of H2S exposure makes well fluid control systems a vital part of sour gas projects, which is where manifold valves play a significant role.
A durable manifold valve installed in a sour gas pipeline regulates gas flow to and from the reservoir while isolating it from potential leak paths. Thanks to their non-corrosive materials, these valves can maintain a secure, reliable seal for several months to a couple of years before needing replacement.
