Hollow fiber membrane process for the pretreatment of methane hydrate from landfill gas

Hollow fiber membrane process for the pretreatment of methane hydrate from landfill gas

Landfill gas is major source of green house effect because it is mainly composed of CH sub(4) and CO sub(2). Especially, the separation of CH sub(4) from landfill gas was studied actively due to its high heating value which can be used for energy resource. In this study, polymeric hollow fiber membr...

Description
Summary:Landfill gas is major source of green house effect because it is mainly composed of CH sub(4) and CO sub(2). Especially, the separation of CH sub(4) from landfill gas was studied actively due to its high heating value which can be used for energy resource. In this study, polymeric hollow fiber membrane was produced by dry-wet phase inversion method to separate CH sub(4) from the landfill gas. The morphology of the membranes was examined by scanning electron microscopy (SEM) to understand and correlate the morphology with the performance of the membrane. Firstly, single gas permeation and mixed gas separation were performed in lab-scale. After then, a pilot scale membrane process was designed using a simulation program. The manufactured process settled in Gyeong-ju landfill site and operated at various conditions. As a result, CH sub(4) was concentrated to 88 vol.% and also CO sub(2) removal efficiency increases up to 86.7%.
