Umthengisi we-DTPMP eMzantsi Afrika

Yintoni i-DTPMP?

I-DTPMP (i-diethylene triamine pentamethylene phosphonic acid, ekwayi-DTPMP) yi-organophosphonate enobunzima obuphezulu beemolekyuli enamaqela amahlanu e-phosphonic acid, enika amandla okuthintela isikali esomeleleyo kunye nokusebenza kozinzo lwesinyithi okugqitha oko kwe-lower-phosphonate-count inhibitors (HEDP, ATMP) kwiimeko zobunzima obuphezulu, i-pH ephezulu, kunye neemeko zamanzi ezishushu kakhulu. Iindawo zayo ezintlanu zokudibanisa i-phosphonate zinika i-DTPMP ulwalamano olukhethekileyo lwee-calcium, i-magnesium, i-iron, kunye nee-manganese ions, nto leyo eyenza ukuba isebenze kwiintlobo zesikali ezinzima ukuzilawula ngee-phosphonates ezilula, ngakumbi i-barium sulfate (BaSO₄) kunye ne-strontium sulfate scale eqhelekileyo kwiinkqubo zamanzi eziveliswa yi-oyile.

Ukuthintela Isikali kunye Nokuzinziswa Kwesinyithi

Kwiinkqubo zamanzi okupholisa ezisebenza kumanqanaba aphezulu (imijikelo ephezulu yoxinzelelo), i-DTPMP ilawula isikali se-calcium carbonate, i-calcium sulfate, kunye ne-calcium phosphate kwimilinganiselo ye-2-5 mg/L. Ukusebenza kwayo okuphezulu kwi-pH ephezulu (8.5-9.5) kunye nobushushu obuphezulu (ukuya kuthi ga kwi-70-80°C) kwenza ukuba ibe yi-phosphonate ekhethwayo kwiinkqubo zamanzi okupholisa ezisebenza kakhulu. Kwiinkqubo zebhoyila zoshishino, i-DTPMP isetyenziselwa ukuzinzisa intsimbi enyibilikisiweyo (ukuthintela i-iron oxide kunye ne-iron phosphate deposits) kunye nokulawula isikali se-calcium. Ukuzinziswa kwentsimbi - ukuthintela intsimbi ekubeni ingabi namanzi njenge-iron oxide okanye i-hydroxide deposits ezibangela ukungcola okubomvu kwiinkqubo - ngumsebenzi wesibini obalulekileyo we-DTPMP, ngakumbi kwiinkqubo ezinamanzi okuzenzela ane-iron.

Izicelo ze-Oilfield kunye ne-Membrane

Kwi-oilfield injection water kunye neenkqubo zamanzi eziveliswayo, i-DTPMP isetyenziselwa ukuthintela i-barium kunye ne-strontium sulfate scale — phakathi kweentlobo ze-scale ezingenakunyangwa, ezifuna ulungelelwaniso oluqinileyo lwe-phosphonate ukuze kuthintelwe. Kwiinkqubo ze-reverse osmosis (RO) membrane, i-DTPMP sisithako kwi-antiscalant formulations kwiinkqubo ezisebenza ngamanzi ane-sulfate ephezulu, i-calcium ephezulu, okanye i-barium feed water ephezulu. I-Terracore Chemicals inikezela nge-DTPMP njengesisombululo samanzi esimalunga ne-50% kwizicelo zonyango lwamanzi kuMzantsi Afrika wonke.
