isibhakabhaka somoya sokuqala esikhundleni kwezintaba (PSA) zokugcinwa
Amaphandle yomsebenzi wokuphucula kwezinye izikhathi (PSA) zokukhulula okushesha ezikwenzekayo, bavakalise ukuthi ngokulandelayo umthetho omphumelelo lokusebenza amaxhobo aokushesha esihlalene nokuhlola izinto ezintsha ezisetyenziswa ukusuka ukuhlola i-oxygen kumoya wesibhedlela. Oku kuhlukanisa nge-izikhathi ezisetyenziswa ezinomsindo, apho imoya engculweni yakhiphiwe uphase phakathi komkhosi ongathathwa, okungayitholakaliyo i-nitrogen ngokubanzi kunye nomncane womphilo we-oxygen. Umsebenzi ungena eminye imiphazamo: ukuphucula, apho imoya iphuculwa kunye nokufilitera, kunye nokuphuma, apho i-nitrogen etholakaliwe yasusiwe phakathi komoya wesibhedlela. Amaphandle eziphambili zakhipho lwePSA zingabhedelela lethe 95%, ukugcizelela ukuba kube ngenxa yesikhatsi somphilo sokuthi zikhona kuzama ukusetshenziswa kwindawo yokugcina nokuthi yeziqhutyeni zeziqala. Izikhunzi zikhethwe ngokubhekeka kakhulu, zisetshenziswa ukubheka kakhulu kulo msebenzi oophendliwe, kwi-phasing kunye nokuthuthukiswa kwe-oxygen, ukusure ukuthi ubuncinci bekhona kuzama ukusetshenziswa.
