Ukulinganiswa kokuhamba kweAmmonia

I-Ammonia, ikhompawundi enobuthi neyingozi, ibaluleke kakhulu kwizicelo ezininzi zoshishino ezifana nokuveliswa kwezichumiso, inkqubo yokupholisa yemizi-mveliso kunye nokunciphisa i-nitrogen oxides. Ngenxa yoko, ukubaluleka kwayo kwimimandla eguquguqukayo kuphakamisa iimfuno ezingqongqo zokhuseleko, ukusebenza kakuhle kunye nokuchaneka. Ukulinganiswa ngokuchanekileyo kokuhamba kwe-ammonia ekucutshungulweni kwemizi-mveliso okusebenzayo akusiyomfuneko yobugcisa kuphela, kodwa ikwayimfuneko yokhuseleko.

Ukukhetha imitha yokuhamba efanelekileyo ye-ammonia kwenza umahluko ekuphatheni iimpawu ezahlukeneyo ze-ammonia yegesi kunye neyolwelo kwimibhobho yemizi-mveliso. Emva koko idatha echanekileyo kunye neziphumo ezithembekileyo ezifana ne-4-20mA, i-RS485, okanye imiqondiso ye-pulse zinokujongwa kwaye zirekhodwe ukuze kulungiswe ngexesha langempela. Abaqhubi bayakwazi ukwenza ngcono iinkqubo ngokuhambelana nemigangatho yokhuseleko.

Ukongeza kulawulo oluchanekileyo kwiinkqubo, ukulinganiswa kokuhamba kwe-ammonia kuyadingeka kuzo zonke iikhonkco ukunciphisa iingozi ezibangelwa yi-NHx enobuthi, enokubangela ukurhawuzelelwa emehlweni, empumlweni, emqaleni xa kuxinana okuphantsi. Kwaye kubangele ukudumba okukhulu kunye nokutsha ngakumbi xa kuchaphazeleka kakhulu. Ukuvezwa kwi-ammonia exineneyo kunokukhokelela ekungabonini, ekungakwazini ukuphefumla kwanokufa.

I-Ammonia yeGesi kunye ne-Ammonia yolwelo

I-ammonia yegesi kunye neyolwelo yahlukile kwiipropati ezahlukeneyo kunye nokusetyenziswa kwemizi-mveliso. Umahluko ophawulekayo phakathi kweentlobo ezimbini ze-ammonia uchaphazela kakhulu ukuphathwa, ukugcinwa kunye nezisombululo zokulinganisa. I-ammonia yegesi yenziwe ngee-athomu ze-nitrogen kunye nee-athomu ze-hydrogen, ezibola kumaqondo obushushu aphezulu ukuze zenze i-nitrogen kunye ne-hydrogen. Ngaphezu koko, i-ammonia yegesi iguquka ibe yi-nitric oxide ngoncedo lwe-catalyst phantsi kweemeko ezifanelekileyo.

I-ammonia enetyhefu yegesi iyabola kwaye isabela ngamandla kumswakama xa idibana namanzi kunye neenwebu ze-mucous. I-ammonium hydroxide eveliswayo iyingozi kakhulu kwaye iyingozi kwizicubu.

I-ammonia engamanzi yimiphumo yokunyibilikisa igesi ye-ammonia emanzini, eyaziwa ngokuba yisisombululo se-ammonia esimanzi, esiluhlobo lolwelo olungenambala oluguquguqukayo olunevumba elibi. Iimpendulo ezinokubakho zobushushu kufuneka ziphathwe ngononophelo xa i-ammonia idibana namanzi. I-ammonia engamanzi iyaphela xa ivezwa emoyeni, ibuyele kwimo yegesi. Olunye uphawu kukuba inokunyibilikiswa kwi-organic solvents ezifana ne-alcohols kunye ne-ethers ngokulula.

Iimfuneko zoMlinganiselo kunye noLawulo lokuHamba koMbane

Ngenxa yeempawu zekhemikhali zokubola kunye nezinye iimpawu zekhemikhali ze-ammonia yegesi, ukukwazi ukujikeleza okufanelekileyo kubalulekile xa ukhetha imitha yokuhamba echanekileyo ngaphandle kokuphazamiseka ngokuchanekileyo. Ukuhanjiswa kwe-ammonia efanelekileyo kufuna iimitha zokuhamba ngokuchanekileyo okuphezulu. Kwaye impawu yokulinganisa ukuhamba kwemitha yokuhamba kufuneka ibe yimfuneko ukuze imelane neemeko ezinzima zendalo.

Izinto ezitshintshayo zokusebenza ezifana nobushushu, uxinzelelo kunye ne-viscosity kufuneka ziqwalaselwe ukuze kulinganiswe izinto ezizinzileyo nezichanekileyo. Ukulungiswa kobushushu kuluncedo ekugcineni ukufundwa okuchanekileyo ngenxa yendlela esebenza ngayo ngokwahluka kobushushu.

Imingeni yoKulinganiswa kweGesi yeAmmonia

Lilonke, kukho imingeni eyahlukeneyo ekulinganisweni kwegesi kunye ne-ammonia yolwelo.

✤Ukuguquguquka okuphezulu kunye nokusabela ngokukhawuleza

✤Iimpawu ezikonakalisayo nezinobungozi

✤Inyibilika kwizinyibilikisi zendalo

I-Ammonia isetyenziswa njani kwiMveliso?

Eyona ndlela ibalaseleyo yokusebenzisa i-ammonia e-USA ngumthombo onamandla we-nitrogen ekukhuleni kwezityalo. Ngaphezulu kwe-80% ye-ammonia isetyenziselwa ukuvelisa izichumisi eziqinileyo kwicandelo lezolimo. Ezo zichumisi ziqinileyo zinokufakwa ngqo emhlabeni okanye ziguqulwe zibe ziityuwa ezahlukeneyo ze-ammonium. Njengoko sonke sisazi, ukongezwa kwe-nitrogen kunefuthe ekukhuleni kokulinywa kwengqolowa yokutya okukhulu.

Sebenzisa kakuhle iipropati zekhemikhali ze-ammonia ezikhethekileyo kwinkqubo yokupholisa yemizi-mveliso. Ubushushu obukhulu bunokufunxwa kwi-ammonia yegesi ngexesha lokunyibilika, ukufikelela kwinjongo yokugcina amaqondo obushushu aphantsi kwindawo encinci. Ngoko ke le propati ingentla ishiya i-ammonia yenye yezona friji zisebenzayo kakhulu kwiindlela ezisebenzayo.

Umzekelo, iifektri zokucubungula ukutya zifuna iifriji zoshishino ukulawula ubushushu. Iimpahla ezibolayo zihlala zikwimeko entle kwaye zilungile ngokuhambelana nemigangatho engqongqo yococeko nokhuseleko lokutya. Ikhethwa phakathi kwezinye iifriji ngenxa yokusebenza kwayo okuphezulu kokupholisa. Ngaphezu koko, impembelelo yayo encinci kwindalo ilandela iindlela zangoku zokunciphisa ukukhutshwa kwekhabhoni kunye neendleko zamandla.

I-Ammonia itshintsha indlela ekhutshwa ngayo i-nitrogen oxides. Ngokubanzi, ifakwa kwi-reaction kunye ne-nitrogen oxides xa izama ukuziguqula zibe yi-nitrogen kunye namanzi kwi-selective catalytic reduction (SCR) kunye ne-selective non-catalytic reduction (SNCR). Ii-nitrogen oxides, ezinegalelo eliphambili kungcoliseko lomoya kunye nemvula ene-asidi, ziyakwazi ukuguqulwa zibe ngumxholo ongenabungozi emva kwe-SCR kunye ne-SNCR.

Ichanekileumlinganiselo wokuhamba kwe-ammoniaIkhula ibalulekile kwimizi-mveliso esebenza ngokuzenzekelayo kunye nemigca yokucubungula ukugcina ukuthotyelwa kwemithetho kunye nokusebenza kakuhle kokunciphisa i-NOx, apho ukuphambuka okuncinci kunokuchaphazela ukusebenza kwenkqubo kunye neziphumo zokusingqongileyo.
