1. Ukusetyenziswa ekucoceni iChelating
Ii-Chelating agents, ezaziwa ngokuba zii-complexing agents okanye ii-ligands, zisebenzisa i-complexation (coordination) okanye i-chelation yee-chelating agents ezahlukeneyo (kuquka ii-complexing agents) ezinee-scaling ion ukuvelisa ii-soluble complexes (ii-coordination compounds) ngeenjongo zokucoca.
Ii-surfactantszidla ngokufakwa ekucoceni ii-agent ze-chelating ukukhuthaza inkqubo yokucoca. Ii-agent ze-inorganic complexing ezisetyenziswa rhoqo ziquka i-sodium tripolyphosphate, ngelixa ii-agent ze-organic chelating ezisetyenziswa rhoqo ziquka i-ethylenediaminetetraacetic acid (EDTA) kunye ne-nitrilotriacetic acid (NTA). Ukucocwa kwee-agent ze-chelating akusetyenziselwa kuphela ukucoca iinkqubo zamanzi okupholisa kodwa kukwabone uphuhliso olukhulu ekucoceni ii-scales ezinzima ukunyibilika. Ngenxa yokukwazi kwayo ukuxilonga okanye ukuxilonga ii-ion zesinyithi kwii-scales ezahlukeneyo ezinzima ukunyibilika, inika ukusebenza okuphezulu kokucoca.
2. Ukusetyenziswa kwi-Heavy Oil Fouling kunye ne-Coke Fouling Cleaning
Kwizityalo zokucoca ipetroliyam kunye neekhemikhali zepetroleum, izixhobo zokutshintsha ubushushu kunye nemibhobho zihlala zinengxaki yokungcoliswa kakhulu kweoyile kunye nokufakwa kwe-coke, nto leyo efuna ukucocwa rhoqo. Ukusetyenziswa kwezinyibilikisi ze-organic kuyingozi kakhulu, kuyatsha, kwaye kuyaqhuma, ngelixa iindlela zokucoca i-alkaline ngokubanzi zingasebenzi ngokuchasene nokungcoliswa kweoyile kunye ne-coke.
Okwangoku, izicoci ze-oyile ezixinzelelweyo eziphuhliswe apha ekhaya nakwamanye amazwe zisekelwe kakhulu kwi-composite surfactants, eziquka indibaniselwano ye-nonionic kunye ne-anionic surfactants ezininzi, kunye nabakhi be-inorganic kunye nezinto ze-alkaline. I-composite surfactants ayivelisi nje kuphela iziphumo ezifana nokumanzisa, ukungena, ukuxuba, ukusasazwa, ukunyibilika, kunye nokufutha kodwa ikwanakho nokukwazi ukufunxa i-FeS₂. Ngokubanzi, ukufudumeza ukuya kuthi ga kwi-80°C kuyafuneka ekucoceni.
3. Ukusetyenziswa kwi-Biocides zamanzi abandayo
Xa kukho i-microbial slime kwiinkqubo zamanzi okupholisa, kusetyenziswa ii-biocides ezinga-oxidizing, kunye nee-surfactants ezingezizo ii-ionic ezinegwebu eliphantsi njengezisasazi kunye nezingena, ukuphucula umsebenzi wee-agents nokukhuthaza ukungena kwazo kwiiseli kunye nomaleko we-mucus wefungi.
Ukongeza, ii-biocides zetyuwa ye-quaternary ammonium zisetyenziswa kakhulu. Ezi zezinye ze-cationic surfactants, ezona zixhaphakileyo yi-benzalkonium chloride kunye ne-benzyldimethylammonium chloride. Zinika amandla aqinileyo e-biocidal, kulula ukuzisebenzisa, zinobuthi obuphantsi, kwaye zibiza kancinci. Ngaphandle kwemisebenzi yazo yokususa i-slime kunye nokususa ivumba emanzini, zikwanazo neziphumo zokuthintela ukugqwala.
Ngaphezu koko, ii-biocides ezenziwe nge-quaternary ammonium salts kunye ne-methylene dithiocyanate azinazo nje kuphela iziphumo ze-biocidal ezibanzi kunye ne-synergistic kodwa zikwathintela ukukhula kwe-slime.
