The Ultimate Guide to Low Emission Valve
Poor-quality valves will eventually begin to leak, especially if they are often used but not well maintained. The "stem" or shaft connecting the handle to the ball, butterfly, or diaphragm is where they typically leak. There is packaging all around that stem. This prevents the controlled gas or liquid from escaping. With gas, leaks are far more likely. A housing or "bonnet" around the stem is filled with packing in a large industrial low emission valve. The packing is a part of the valve body in smaller valves. Regular use of a valve causes the packing surrounding the stem to begin to deteriorate. If the stem becomes soiled, twisting it might force the dirt into the packing and hasten packing wear.
Fugitive emissions, which are described as "emissions which could not reasonably travel through a stack, chimney, vent, or other functionally equivalent openings," are leaks from valves.
Gases are the key issue, especially those that can be dangerous. One substance that can cause harm to anyone working or living close by is chlorine. A low emission packing valve must be in poor condition in order to leak liquid, but if it were located in a chemical or refinery plant, it might evaporate and pose a threat. You'll get into problems if you do something similar with the EPA or the Department of Environmental Quality in your state. However, even if the leak isn't dangerous, you'll still have to pay for it. That's just because any leak results in product waste. A 3.6 trillion cubic foot annual loss of natural gas into the atmosphere has been calculated for the entire world.
Chemical factories, especially oil and gas facilities, cannot ignore the issue. They ought to start by implementing a Leak Detection and Repair Program. In order to detect leaks, someone must patrol the area while carrying an electronic "sniffer." Another thing that cannot be done casually is real sniffing. When looking for fugitive emissions, the EPA expects organizations to use "Method 21." This specifies the precise procedure for conducting the tests.
Your chance of difficulties can be decreased by three steps. First, invest in high-quality valves rather than cheap ones. Secondly, maintain your valves regularly. Keep the stems clean and, if necessary, tighten the nut or bonnet on the valve's top. Third, search for valves marked as low emission valves (Low-E) or employ Low Emission packing if you are working with dangerous gases.
