“Nasib” CO2 setelah ditangkap

Pernah ada pertanyaan di forum penelitian, setelah CO2 ditangkap terus diapakah gas tersebut ? Itu untuk penelitian penangkapan CO2 dengan adsorption. Apakah adsorbent yang sudah jenuh disimpan aza ? Itu namanya memindahkan masalah ke masalah lain. Lagi baca-baca jurnal tentang penangkapan CO2 keluar jawaban untuk hal di atas. Meskipun ini untuk absorption, bisa juga untuk metode penangkap CO2 yang lain :-).

The process for post combustion capture consists of four stages as sketched in Fig. 1. First, CO2 is removed from the flue gas by absorption in a packed absorber column. Then ‘rich’ solvent containing CO2 is led to a desorber column and heated in a reboiler to release the CO2. Next, CO2 is compressed and transported to a geological storage site or injected into an oil and gas reservoir. Finally the regenerated ‘lean’ solvent is recycled to the absorber.
