Sulfuric acid. Hababka loo diyaarinta. codsiga

Sulfuric acid ayaa si ballaaran loo isticmaalo beeraha kala duwan ee hawlaha aadanaha. warshadaha kiimikada Modern waxaa ka mid ah in liiska ee wax soo saarka ugu weyn, heerka ay sii daayo waa tilmaame aan tooska ahayn ee iman kara ee wax soo saarka kiimikada ee dal ka. Sanad kasta dunida soo saartaa oo ku saabsan 160 million tons oo ah walaxda.

Sida laga soo xigtay guryaha ay physico-kiimikada, acid ee sulfuric acid waa a dicarboxylic, this xarunta of baaruud gaadho gobolka ugu sareeya ee lagu qayilo (6). Under xaaladaha caadiga ah, xaalad acid sulfuric ka xoog ka dhigan dareere culus saliid isagoo midab lahayn, waxna urin. Sulfuric acid waxaa loo isticmaalaa in xal. Sida dareeraha waxaa loo isticmaali karaa sida biyo caadi ah, iyo trioxide baaruud. Waxaa la arkaa in xal aqueous, haddii saamiga tirada taagoo of trioxide baaruud in xaddiga biyaha ka yar tahay midnimo. Kor hadal index this waxaa loo isticmaalaa - xal trioxide baaruud in acid sulfuric ama oleum.

Sulfuric acid-soo-saarka waxay bixisaa this Bacriminta macdanta habka wax soo saarka abuurka qiimo leh, waxaa loo isticmaalaa sida elektrolytka ah in a batari hogaanka-acid, acid ah waa qayb weyn ka diyaarinta cusbada kala duwan macdanta iyo acids. Chemical fiiloyin, formaldehyde, qiiq-dhalin iyo waxyaabaha qarxa ee technology-saarka ay waa sulfuric acid. Ma suurtowdo in la qiyaaso saliid, biraha, dharka, maqaar iyo kuwa kale ee warshadaha.

Xitaa warshadaha cuntada mid aan jirin oo aan isticmaalka walaxda - helitaanka E513 daro cuntada (emulsifier). Industrial Organic Avv, fuuqbax (habka for esters helo, ether preservative), fuuq (saarka ethanol ka ethylene) sulfonation (wax soo saarka ee saabuunta iyo intermediates diyaarinta formaldehyde), alkylation (isooctane Avv, caprolactam, tones polyetylen), Beeyada kabashada filtarrada for khadadka-soo-saarka biyo arimaha debeda - midkoodna hawlgaladaa ma jiro isticmaalka sulfuric acid.

Production of sulfuric acid siisaa macaamiisha ugu badan ee aasaasiga ah oo ka mid ah walaxda - Bacriminta Avv. Tusaale ahaan, si loo soo saaro tan ah ee Bacriminta phosphate waa lagama maarmaan in la qaataan labo ilaa tan saddex iyo badh oo sulfuric acid. Sababtan awgeed, shirkadaha acid sulfuric dhiibtay wax soo saarka ee acid sulfuric, isku dhafan oo warshadood oo soo saara dhismaha Bacriminta.

laba hab processing waxaa loo isticmaalaa wax soo saarka ee sulfuric acid. Sulfuric acid-soo-saarka waa habka xiriir weyn iyo waa sagaashan boqolkiiba, habka nitrus (Tower) ayaa baahsanaanta yar. Inkastoo ceebaha iyo heshaan kasta, wax soo saarka ee acid sulfuric ka pyrites nitrus barakacay marayo qaab soo jiidasho kharashka, nadaafadda, iyo ka-fiirsashada sare ee alaabta la dhammeeyayna ay at outlet ah.

Barashada habka xiriir sulfuric acid warshad Avv, wax soo saarka ee acid sulfuric u ogolaanaya kala qaybiyey saddex marxaladood. Marxalada koowaad, galidda pyrite, ujeedada in foornada dubista ee lagu magacaabo "sariirta buusho" ah. Heerka labaad waxa ay ku lug leedahay qayilo ee baaruud in xabagta baaruud (VI) dioxide, iyo marxaladda saddexaad waa diyaarinta oleum, oo waxaa lagu tuuraa on taangiyada iyo soo diray in macaamiisha.

Habka nitrus saarka sulfuric acid ayaa helay isticmaalka ballaaran sababtoo ah wax soo saarka saarka khayroon daahirnimo ku filnayn, sidaas yareysey isticmaalkeeda.

Marka laga farsamooyinka iyo hababka diyaarinta, wax soo saarka ee acid sulfuric u baahan saarayaasha inuu siinayo ilaalinta deegaanka dareenka sii kordhaya.
