A common misconception is that the quality of renewable natural gas is inferior to that of fossil natural gas as it contains higher levels of contaminants compared to fossil natural gas. But this has proven to be untrue. The Gas...
Gas detection equipment can help detect and locate gas leaks and are an essential safety tool on sites where gas could potentially escape and pose a safety hazard to workers or the surrounding communities. However, from time to time, you...
The two main barriers that could potentially pose a challenge to a renewable natural gas project, include economic barriers, as discussed in our previous post, and technical barriers. This article examines some of the technical barriers to RNG project development....
(image courtesy: pxfuel.com) There are two primary economic barriers to RNG that can prevent an RNG project from getting off the ground: economic challenges and technical challenges. In this article we will look at some of the economic barriers RNG...
Oxygen Removal from Natural Gas Natural gas utilities often set stringent limits for oxygen in renewable natural gas that is injected into their natural gas pipeline network. Since high oxygen levels can promote corrosion of the pipeline infrastructure, utilities tend...
Depending on how much nitrogen is present in the biogas, it may be necessary to remove or reject nitrogen in order to comply with renewable natural gas (RNG) specifications. Since biogas collected from landfill sites is more likely to be...
VOC and siloxane removal from biogas captured on landfills forms an essential part of the purification process when landfill gas is used as a vehicle fuel or injected into a natural gas pipeline. Since the presence of siloxanes, even at...
In order for RNG to meet the standards required for use as vehicle fuel or injection into a natural gas pipeline it needs to have impurities such as carbon dioxide removed. There are currently four methods that are typically employed...
Depending on what feedstock is used in the digestion process, the raw biogas that is collected from the biodigester typically consists of between 45-65% flammable methane, with several impurities making up the balance. When the biogas is used to produce...
