Porous Material Polymerizes Carbon Dioxide At Natural Gas Wellheads

Rice University scientists have created an earth-friendly way to separate carbon dioxide from natural gas at wellheads. A porous material invented by the Rice laboratory of chemist James Tour sequesters carbon dioxide, a greenhouse gas, at ambient temperature – with pressure provided by the wellhead – and lets it go once the pressure is released. The material shows promise as a replacement for more costly and energy-intensive processes.
