Natural gas decarburization (decarbonization) skid, bụ isi ngwaọrụ na-asachapụ ma ọ bụ ọgwụgwọ gas.

Ọdịnaya nke carbon dioxide na ọkọlọtọ mma gas ekwesịghị ịbụ ihe karịrị 3%. Na carbon dioxide na mmiri mgbe ígwè nwere nnọọ ike corrosive. Ọ bụrụ na uru PH bụ otu, oke acidity nke carbon dioxide dịkwa elu, yabụ ogo corrosion nke carbon dioxide na ígwè dịkwa elu.

Nrụgide swing adsorption (PSA) bụ teknụzụ ọhụrụ eji kewaa ngwakọta gas na teknụzụ nkewa mgbasa ozi. Tụnyere usoro mmịnye kemịkalụ ọdịnala, teknụzụ PSA na-adọrọ mmasị n'ụzọ akụ na ụba maka iwepụ na mgbake nke H2S na CO2 site na gas sitere n'okike, a na-emepụtakwa ya nke ọma.
