Capturing Latent Methane Emissions from Natural Gas Production

点击翻译按钮获取中文摘要

Methane is 21 times more potent than carbon dioxide as a greenhouse gas. The natural gas industry produces significant methane emissions through collateral venting with nitrogen gas. Recovering waste methane will reduce greenhouse gas emissions and increase the revenue of natural gas processors. This project will develop the technology needed to capture the latent methane and significantly reduce its concentration in nitrogen gas rich vent streams. New adsorbents for separating these gases, such as molecular trapdoor zeolites, will be designed and tested over wide ranges of pressure and temperature. Dual reflux pressure swing adsorption cycles will be tested using the best materials to demonstrate how latent methane emissions can be reduced to part-per-million levels.
