Iimpawu zenkqubo yokulungisa amanzi amdaka eseleyo, inkqubo yokulungisa amanzi amdaka enebhedi esisigxina ifundwe yaza yashwankathelwa, kwaye ezi mpawu zilandelayo zishwankathelwe: Okokuqala, ibhedi yokusabela eyahlukileyo okanye iindawo ezahlukeneyo zebhedi efanayo kukho umahluko phakathi kwe-1) i-hydrotreating reaction yi-exothermic reaction, kwi-reactor yezimboni, ukunyuka kobushushu kwibhedi efanayo, umaleko webhedi 2) ubushushu obuphantsi bokusabela buphezulu, into esebenzayo kwindawo yokuqala, inxalenye ephezulu yebhedi okanye impendulo yebhedi yokuqala, kunye nezinto zokusabela ezantsi kwebhedi okanye impendulo yebhedi elandelayo 3) uxinaniso lwe-reactant yebhedi ephezulu luphezulu, kwaye uxinaniso lwe-reactant yebhedi esezantsi luphantsi okanye ukuguqulwa kwe-reaction yebhedi ephezulu kuphezulu, umthwalo mkhulu 4) i-hydrotreating reaction kunye nokuvelisa i-hydrogen sulfide kunye ne-ammonia, ukusetyenziswa kwe-hydrogen isizathu, umaleko webhedi ophezulu kunye nomgangatho osezantsi we-H2 concentration ye-H2S kunye ne-NH3 eyahlukileyo, i-oyile eseleyo iqulethe inani elikhulu lokungcola kunye nezinto ezingezizo ezifanelekileyo, ubunzima bayo obuphakathi beemolekyuli, i-viscosity ephezulu, ekhokelela ekusebenzeni okuphantsi kokuphendula, ukucima i-catalyst, ngoko ke i-residue hydrotreating process ifuna iimeko zokusebenza, uxinzelelo oluphezulu kunye nobushushu, isantya sendawo esisezantsi kwisithathu, intsalela eveliswayo Kwinkqubo ye-hydrogenation yebhedi esisigxina, i-coke kunye ne-metal sulfide kunye nezinye izinto eziqinileyo ziya kubangela ukuba umahluko woxinzelelo lwebhedi unyuke de kufikelelwe kumda woyilo, isixhobo sanyanzeleka ukuba sivale. Okwesine, inkqubo yokulungisa intsalela ye-hydrotreating kufuneka yamkele itekhnoloji yokudibanisa i-catalyst.
