Inline K2CO3 Concentration Measurement in the Benfield Process

TheNjira ya Benfieldndi mwala wapangodya wa mafakitalekuyeretsa gasi, yomwe imatengedwa kwambiri m'mafakitale opangira mankhwala kuti achotse carbon dioxide (CO2) ndi hydrogen sulfide (H2S) kuchokera ku mitsinje ya gasi, kuonetsetsa kuti zotulukapo zoyera kwambiri zimagwiritsidwa ntchito mu kaphatikizidwe ka ammonia, kupanga haidrojeni, ndi kukonza gasi. Kuwongolera kukhazikika kwa njira yotsukayi ndikofunikira kuti tipewe zovuta zogwira ntchito monga kuchita thovu, kuchepetsa kuyamwa bwino, kapena kuwonongeka kwa zida.Mzere wa potassium carbonate concentration mitandipotassium carbonate concentration analyzersperekani njira yosinthira popereka kuwunika kosalekeza, munthawi yeniyeni kwa milingo ya K2CO3 ndi potaziyamu bicarbonate (KHCO3), kupangitsa ogwiritsa ntchito kukhathamiritsanjira yoyeretsera gasindi kupeza ndalama zopulumutsa.

Bukhuli lathunthu likuwunika makina aNjira ya Benfield yochotsa mpweya wa asidi, ndi ubwino wawo kwa mafakitale mongazomera zopanga ammonia,zomera zopanga haidrojeni,malo opangira gasi,zomera petrochemical,mwachindunji chitsulo kuchepetsa zomera,ndimalo opangira malasha. Mwa kuphatikiza zida zapamwambazi, ogwira ntchito pamakampani amatha kupititsa patsogolo ntchito zake, kuwonetsetsa kuti akutsatira malamulo okhwima, ndikupereka mpweya wabwino kwambiri.

Chemistry ndi Mechanics a Benfield process

TheNjira ya Benfield, yopangidwa ndi US Bureau of Mines ndipo yapatsidwa chilolezo ndi UOP (tsopano ndi gawo la Honeywell), ndi njira yosungunulira yotenthetsera, yozungulira yomwe imagwiritsa ntchito njira yotentha ya K2CO3 kuchotsa CO2 ndi H2S ku mitsinje ya gasi. Ndi njira yodalirikakuyeretsa gasim'mafakitale omwe amafunikira mipweya yoyera kwambiri, monga kaphatikizidwe ka ammonia kwa feteleza, kupanga haidrojeni pakuyenga, ndi kukonza gasi wachilengedwe pamapaipi. Njirayi imagwira ntchito m'magawo awiri akuluakulu: kuyamwa ndi kusinthika.

Panthawi yoyamwitsa, mpweya wa mpweya umayambitsidwa pansi pa mzere wa absorber, ukuyenda potsutsana ndi njira yotentha ya K2CO3 (nthawi zambiri 20-30 wt%) pa kutentha pakati pa 100 ° C ndi 110 ° C ndi kupanikizika kwakukulu.

H2S imatengekanso, ndikupanga zinthu zina zomwe zimachitikira. Mpweya woyeretsedwa umatuluka pamwamba pa chotsitsa, pamene yankho lolemera, lodzaza ndi KHCO3, limasamutsidwa ku regenerator (stripper). Mu gawo la kubadwanso, yankho limatenthedwa ndi nthunzi kapena kuchepetsedwa, kutembenuza zomwe zimachitika kuti amasule CO2 ndi H2S, potero amatsitsimutsa njira ya K2CO3 kuti igwiritsidwenso ntchito. Njira yozungulira iyi imatsimikizira kuti ikugwira ntchito mosalekeza, koma kugwira ntchito kwake kumadalira kusunga mayendedwe oyenera a K2CO3 ndi KHCO3 kuti apewe zovuta.

Chifukwa Chake Kuwongolera Maganizo Ndikofunikira

Kuwongolera kolondola kwa njira ya K2CO3 ndikofunikira pazifukwa zingapo. Miyezo yambiri ya KHCO3 imatha kuyambitsa thovu mu chotengera, chomwe chimasokoneza kukhudzana ndi madzi a gasi, kumachepetsa kuyamwa kwa CO2, ndikuwononga zida zowonongeka. Mosiyana ndi zimenezi, kuchuluka kwa K2CO3 kosakwanira kumachepetsa mphamvu ya yankho la kuyamwa mpweya wa asidi, zomwe zimapangitsa kuti pakhale kuyeretsedwa kosakwanira komanso kusagwirizana ndi zomwe zatchulidwa. Kuphatikiza apo, kuyika molakwika kumatha kukulitsa kugwiritsa ntchito mphamvu panthawi yakukonzanso, chifukwa mayankho olemera kwambiri amafunikira nthunzi yochulukirapo kuti atulutse mpweya wogwidwa, ndipo amatha kukulitsa dzimbiri pazida chifukwa chamtundu wa alkaline wa yankho.

M'mbiri yakale, kuyang'anira ndende kunkadalira kusanthula kwamanja ndi kusanthula kwa labotale, njira yomwe imakhala yolemetsa, yochedwa kuchedwa, komanso yosatha kupereka zidziwitso zenizeni zenizeni. Zolepheretsa izi zingayambitse kulephera kwa ndondomeko, kuwonjezereka kwa ndalama zogwirira ntchito, ndi kuphwanya malamulo.Mzere wa potassium carbonate concentration mitakuthana ndi mavutowa popereka miyeso yosalekeza, yolondola, kuthandizira kusintha nthawi yomweyo kuti zinthu zikhale bwino komanso kupititsa patsogolo magwiridwe antchito aNjira ya BenfieldScrubber.

Momwe Inline Concentration Meters Amagwirira Ntchito

Mzere wa potassium carbonate concentration mitakapenaosanthulandi njira zowunikira zapamwamba zopangidwira kuyeza K₂CO₃ndi KHCO₃ndende molunjika mkati mwa ndondomeko mtsinje, kuchotsa kufunika pamanja zitsanzo. Zidazi zimapangidwira kuti zizigwira ntchito pansi pazovuta zaNjira ya Benfield, kuphatikizapo kutentha kwapamwamba (mpaka 110 ° C) ndi kupanikizika, ndipo amamangidwa ndi zipangizo zosagwirizana ndi dzimbiri kuti athe kupirira chilengedwe cha alkaline cha yankho la scrubbing.

Matekinoloje angapo amagwiritsidwa ntchito pamamita awa, iliyonse ikupereka zabwino zake:

Kuyeza kwa Ultrasonic: Mamita amenewa amayezera liŵiro la phokoso kudzera m’madzi, omwe amayenderana ndi kachulukidwe kake ndi kukhazikika kwake. Njirayi simakhudzidwa ndi njira yothetsera vutoli, mtundu, kapena kuwonekera, ndikupangitsa kuti ikhale yodalirika kwambiriMalingaliro a kampani Benfield Process₂kuchotsa. Ndi miyeso yolondola ya 0,05% mpaka 0.1%, akupanga ndende mamita amapereka yeniyeni deta kukhalabe mulingo woyenera kwambiri alkali-to-bicarbonate ratios.

Kuyeza kwa Conductivity: Mamita awa amawunika mphamvu yamagetsi ya yankho, yomwe imasiyana ndi kuchuluka kwa K + ndi HCO3- ions. Conductivity mita ndi yotsika mtengo komanso yoyenera kuyang'anira kusintha kwa ma ionic koma angafunike kubweza kutentha kuti atsimikizire kulondola.

Kachulukidwe Muyeso: Poyesa kuchuluka kwa yankho, lomwe limasuntha ndi gawo la K2CO3 ndi KHCO3, mamitawa amapereka chizindikiro chodalirika cha ndende. Density mita ndi yolondola koma ingafunike kusinthidwa kwa kutentha.

Kuyeza kwa Coriolis: Ngakhale kuti amagwiritsidwa ntchito makamaka poyezera kuthamanga, mamita a Coriolis amathanso kuyeza kachulukidwe ndi kulondola kwakukulu (mwachitsanzo, ± 0.001g/cc), kupereka njira yopanda kugwedezeka yochepetsera kusakanikirana kwa zigawo ziwiri monga K2CO3 ndi KHCO3 zothetsera.

Mamita awa nthawi zambiri amayikidwa mu payipi pakati pa cholowetsa ndi chowonjezeranso kapena pamzere wobwereza, kuwonetsetsa kuwunika kwathunthudongosolo la kuyeretsa gasi. Popereka zidziwitso zenizeni, amathandizira ogwiritsa ntchito kuzindikira ndikuwongolera zopotoka nthawi yomweyo, kupewa zinthu monga kuchita thovu kapena kuyamwa kosakwanira.

Kuyika ndi Kuphatikiza Njira

Kukulitsa mphamvu yapotassium carbonate concentration analyzers, kukhazikitsa njira ndikofunikira. Mamita ayenera kuyikidwa pamalo ovuta, monga payipi yochokera ku choyezera kupita ku regenerator ndi chingwe chowongolera chowongolera, kuti azitha kusintha ndende panthawi yonseyi. Machitidwe owonjezera amatha kutumizidwa kuti awonetsetse kugwira ntchito mosalekeza panthawi yokonza, kuchepetsa nthawi yopuma.

Kuphatikizana ndi machitidwe oyendetsera zomera kumalola kusintha kwa makina, monga kuwongolera dosing ya K2CO3 kapena kulowetsa nthunzi, kutengera nthawi yeniyeni. Kuwongolera nthawi zonse ndi mayankho okhazikika ndikofunikira kuti mukhalebe olondola, makamaka pamikhalidwe yosinthika yaBenfield CO2 kuchotsa njira.
