Propargyl Alcohol Corrosion Inhibitor Supplier

Kuyini i-Propargyl Alcohol?

I-Propargyl alcohol (2-propyn-1-ol, PA) iyinhlanganisela ephilayo enesisindo esincane sama-molecule eneqembu le-alkyne eliyi-terminal (C≡CH) kanye neqembu le-hydroxyl (−OH). Iwuketshezi olucacile, oluhambayo, oluvuthayo olunephunga elimnandi. Kumakhemikhali okuvimbela ukugqwala, i-propargyl alcohol isetshenziswa njengesivimbeli sokugqwala kwensimbi esisebenza kahle kakhulu ezindaweni ezine-acidic - ikakhulukazi ekugayweni kwe-hydrochloric acid (HCl), ekususeni i-sulfuric acid, kanye nezixazululo zokuhlanza i-phosphoric acid. Indlela ye-Propargyl alcohol ukumuncwa: isibopho esiphindwe kathathu (iqembu le-alkyne) sidlula ekusebenzisaneni kwe-catalytic ne-iron surface futhi sikhuthaza ukumuncwa kwe-molecule ephilayo, sakha ifilimu evikelayo e-organic surface yensimbi evimba ukuhlaselwa yi-acid futhi yehlise izinga lokugqwala. Iphinde inciphise ukuminyana kwe-hydrogen kwensimbi enamandla aphezulu ngesikhathi sokuchayeka ku-acid.

Izicelo Zokususa I-Acid Pickling kanye Nezikali

Ukuhlanza nge-asidi nokususa ama-scaling (ukuhlanza nge-HCl noma i-H₂SO₄ ukususa ukugqwala, isikali sokugaya, isikali se-calcium carbonate, noma ama-iron oxide deposits ezindaweni zensimbi) kuveza insimbi eyisisekelo endaweni ye-asidi egqwala kakhulu. Ngaphandle kwesivimbeli sokugqwala, ukuhlaselwa yi-asidi ebusweni bensimbi ehlanzekile (ngaphansi kwesikali) kukhulu futhi kubangela ukulahleka kwensimbi, ukuqhekeka kwe-hydrogen, kanye nokugoba komphezulu. I-Propargyl alcohol, ethathwe ku-0.1–1.0% (1–10 g/L) ebhavini le-asidi, yehlisa kakhulu izinga lokugqwala kwensimbi (ukusebenza kahle kokuvimbela okungu-90–99% ku-15% HCl ku-30–80°C, kuye ngomthamo kanye nokushisa) ngenkathi ivumela i-asidi ukuthi incibilikise isikali kanye nama-deposits. Ihambisana nezinye izingxenye ze-acid pickling inhibitor (ama-iodide ions, ama-surfactants, ama-heteroatom-containing compounds) emikhiqizweni ye-pickling inhibitor eyenziwe.

Izicelo Zokuhlanza Insimu Kawoyela Nezimboni

Emisebenzini yase-oyela, i-propargyl alcohol isetshenziswa ekwakhiweni kwe-acid inhibitor yokuvuselela umgudu (i-HCl matrix acidising, i-acid fracturing) ukuvikela amashubhu ensimbi kanye nemishini ye-wellhead kusuka ku-HCl enokugcwala okuphezulu esetshenziswa ekuvuseleleni ukwakheka kwe-carbonate. Izidingo zokuvimbela i-acid yase-oyela ziyadingakala - ukuvimbela kumele kuhlale kusebenza emazingeni okushisa afinyelela ku-120-150°C ngaphansi kwamazinga aphezulu e-HCl (15-28%) kanye nokucindezela okuphezulu. I-Propargyl alcohol yakha umgogodla wezinhlobo eziningi ze-acid inhibitor zokuhweba, ezihlanganiswe nama-amine aqoshiwe, ama-heterocycles ane-nitrogen, kanye nama-intensifier compounds (iodide, i-cinnamaldehyde) ukuze kwandiswe amazinga okushisa aphezulu. Ekuhlanzeni kwe-heat exchanger yezimboni kanye nokuhlanza amakhemikhali emishini yenqubo, i-propargyl alcohol ivikela izindawo zensimbi ngesikhathi sokuhlanzwa kwe-HCl noma i-citric acid. I-Terracore Chemicals inikeza i-propargyl alcohol kuma-drum angu-25 kg kanye no-200 kg ngaphansi kokuhlukaniswa koketshezi oluvuthayo.
