Imishini yokwelapha igesi ekhishwayo iyithuluzi elibaluleke kakhulu elingakwazi ukwelapha igesi ephumayo ekhiqizwa ezimbonini, ezindaweni zokusebenzela, noma kwezinye izindawo, ukugwema ukulimala kwemvelo nakubasebenzi. Kodwa-ke, akulula ukuzikhethela imishini yokwelapha igesi ephumayo efanele. Kulesi sihloko, sizokwethula indlela yokukhetha imishini yokwelapha igesi ephumayo efanele wena.

Okokuqala, ukuqonda ukwakheka kwamagesi aphumayo kubaluleke kakhulu. Izingxenye ezihlukene zegesi yokukhipha igesi zidinga imishini yokwelapha ehlukene, ngakho-ke ngaphambi kokukhetha imishini yokwelapha igesi ephumayo, sidinga ukuqonda izingxenye zegesi yokukhipha umoya. Uma ukubunjwa kwegesi yokukhipha kungaqinisekile, singayihlaziya ngokuhlolwa kwelabhorethri noma ezinye izindlela.

Okwesibili, kubalulekile futhi ukuqonda izinhlobo zemishini yokwelapha igesi ephumayo. Kunezinhlobo eziningi zemishini yokwelapha igesi yokukhipha umoya, njengamadivayisi e-carbon adsorption esebenzayo, imibhoshongo yokuwasha, amadivaysi e-catalytic oxidation, njll. Idivayisi ngayinye inobubanzi bayo bokusebenza, ngakho-ke lapho ukhetha idivayisi, kuyadingeka ukukhetha ngokusekelwe kuzinto ezifana nokubunjwa kwegesi ephumayo kanye nevolumu yokukhiqiza.

Ngaphezu kwalokho, lapho ukhetha okokusebenza kwegesi ephumayo, izici ezifana nokusebenza kahle kokwelashwa kwemishini kanye nezindleko zokusebenzisa nazo zidinga ukucatshangelwa. Ukusebenza kahle kokucubungula kubhekisela ekusebenzeni kahle kwesisetshenziswa ekwelapheni igesi ekhishwayo, kuyilapho izindleko zokusebenzisa zihlanganisa izindleko zokuthenga, izindleko zokusebenza, kanye nezindleko zokunakekela okokusebenza. Ngakho-ke, lapho ukhetha imishini, kubalulekile ukucabangela lezi zici ngokucophelela.

Bese, ezinye izici zidinga ukucatshangelwa, njengokufakwa nokugcinwa kwemishini. Ukufakwa kwezinto zokusebenza kudinga ukucabangela izici ezifana nesizinda nosayizi wemishini, kuyilapho ukunakekelwa kwezinto zokusebenza nakho kudinga ukucabangela izici ezifana nomjikelezo wokunakekela kanye nezindleko zokuwulungisa.

Ngamafuphi, ukukhetha okokusebenza kwegesi ekhishwayo efanele akulula, futhi kudinga ukucatshangelwa okuphelele kokwakheka kwegesi ekhishwayo, uhlobo lwemishini, ukusebenza kahle kokwelashwa, izindleko zokusebenzisa, nezinye izici. Kuphela ngokukhetha imishini evumelana nawe singakwazi ukwenza kangcono ukwelashwa kwegesi yokukhipha umoya, ukuvikela imvelo kanye nempilo yabasebenzi.
