Makhalidwe a njira yotsalira yothira madzi, njira yothira madzi yotsalira yokhala ndi bedi lokhazikika idaphunziridwa ndikufotokozedwa mwachidule, ndipo makhalidwe otsatirawa adafotokozedwa mwachidule: Choyamba, bedi losiyana la reaction kapena magawo osiyanasiyana a bedi lomwelo pali kusiyana pakati pa 1) hydrotreating reaction ndi exothermic reaction, mu reactor yamafakitale, kutentha kumakwera pabedi lomwelo, bedi losanjikiza 2) kutentha kotsika kwa reaction ndi kwakukulu kwambiri. Chinthu chogwira ntchito poyamba pa bedi lapamwamba kapena bedi loyamba reaction, ndi zinthu zomwe zimachitika pansi pa bedi kapena zotsatira za bedi 3) kuchuluka kwa reactant ya bedi lapamwamba ndi kokwera, ndipo bedi losanjikiza pansi pa reaction ndi lotsika kapena kusintha kwa reaction ya bedi lapamwamba ndi kokwera, katundu ndi wamkulu 4) hydrotreating reaction ndi kupanga hydrogen sulfide ndi ammonia, hydrogen consumption chifukwa bedi lapamwamba ndi pansi la H2 concentration ya H2S ndi NH3 lachiwiri losiyana, mafuta otsala ali ndi zonyansa zambiri komanso zigawo zosayenera, kulemera kwake kwapakati kwa mamolekyulu, kukhuthala kwakukulu, zomwe zimapangitsa kuti magwiridwe antchito otsika a reaction, kuletsa ntchito, kotero njira yothira madzi yotsalira imakhala yovuta, kuthamanga kwambiri ndi kutentha, liwiro la malo lotsika lachitatu, zotsalira zopangidwa Mu njira yokhazikika ya hydrogenation ya bedi, coke ndi sulfide yachitsulo ndi zinthu zina zolimba zimayikidwa pabedi, kuyika kwa zinthu zolimba pabedi kungapangitse kusiyana kwa kuthamanga kwa bedi kukwera mpaka malire a kapangidwe kake atakwaniritsidwa, chipangizocho chinakakamizidwa kutseka. Chachinayi, njira yochotsera madzi yotsalira iyenera kugwiritsa ntchito ukadaulo wophatikizira wolumikizira chothandizira.
