Products Description
Iyo caustic scrubber yekubvisa H₂S (inozivikanwawo sealkaline H₂S scrubber) chishandiso chekuchenesa gasi chinoenderana nemakemikari absorption misimboti.
Musimboti wayo mukuru kuunza iyo H₂S-ine gasi kuti ibatane zvizere necaustic solution (sodium hydroxide kana potassium hydroxide) mune yakarongedzwa kana tireyi shongwe, apo H₂S inopindirana nealkali kuita soluble sodium sulfide (Na₂S) kana sodium hydrosulfide kubva muH₂S (Na₂S) ichibvisa kubva muH₂S.
Inogona kudzikisira kudzika kweH₂S kusvika pazasi 10 ppm, kuve nechokwadi chekuchengetedzwa kwemidziyo yepasi uye kutevedza kwezvakatipoteredza.
Kushanda musimboti
Maitiro ekushanda kweScavenger H2s Kubviswa kunogona kupfupikiswa sematanho mashanu akakosha: gasi pretreatment → absorption reaction → mhinduro kutenderera → kushandiswa kwemhinduro kurapwa → kucheneswa gasi kubuda.
Gasi pretreatment:Iyo H₂S-ine gasi (yakaita segasi rakasvibirira kana refinery off-gasi) inotanga yapinda mudhiramu rekugogodza kuti ibvise madonhwe emvura uye zvidimbu zvakasimba (kudzivisa kuvharidzira kurongedza nekukanganisa kunyura zvakanaka).
Absorption reaction:Pretreated gasi inopinda pasi pe scrubber tower uye inoyerera ichikwira kumusoro, nepo caustic solution (2-10% NaOH) inopfapfaidzwa ichidzika kubva kumusoro. Mumubhedha wakazara (uzere nekurongeka kana kusarongeka), gasi nemvura zvinosangana, uye H₂S inopindirana neNaOH: H₂S + 2NaOH → Na₂S + 2H₂O (kana H₂S + NaOH → NaHS + H₂O, zvichienderana neal).
Solution kutenderera:Iyo caustic mhinduro, mushure mekutora H₂S, inounganidza pazasi peshongwe uye inopombwa ichidzokera kumusoro kuti idzokororwe zvakare. Chikamu chemushonga wakashandiswa chinoramba chichiburitswa kuchengetedza alkali concentration mumvura inotenderera (inowanzodzorwa pamusoro pe2%).
Yakashandiswa mhinduro kurapwa:Iyo yakabviswa yakashandiswa mhinduro (ine Na₂S/NaHS) inotumirwa kune neutralization kana regeneration system. Inogona kurapwa neoxidants (yakadai sehydrogen peroxide) kugadzira mishonga yesarufa isingakuvadzi, kana kuvandudzwa uchishandisa lime kudzorera alkali kuti ishandiswezve.
Yakanatswa gasi kubuda:Iyo H₂S-yakabviswa gasi inobuda kubva pamusoro peshongwe, inopfuura nepainobvisa mhute kuti ibvise madonhwe emvura akaiswa mukati, uye yozotakurwa kuenda kuzasi kana kuburitswa mushure mekusangana kwemaitiro.
Caustic Scrubber yeH₂S Removal Core Features
Kubudirira kwepamusoro kubvisa
Inogona kudzikisira zvakadzikama H₂S kusungwa kubva kuzviuru zveppm kusvika pazasi 10 ppm, nekubudirira kwekubvisa Kukura kupfuura kana kuenzana ne99%, kusangana neyakaomesesa emission standards (seIsingasviki kana kuenzana ne20 ppm yehutsi hwemaindasitiri).
01
Wide capacity range
Single-unit processing capacity inotangira pa100 Nm³/h kusvika 50,000 Nm³/h, inokodzera-zviyero diki (biogas plants) kusvika-zvikero zvakakura (magirodhi ekugadzira gasi) anoyerera.
02
Kukurumidza kupindura
Iko kunyura kunoitwa nekukasira, zvichiita kuti sisitimu ikurumidze kuchinjika kune inlet H₂S concentration (mukati me10-30 maminetsi kuti agadzikane).
03
Kushanda kuri nyore
Maitiro acho ari nyore kudzora, aine maparameta akakosha (alkali concentration, fluid-gasi reshiyo) inogadzirika kuburikidza nemasisitimu anongozviitira kuti kushanda kwakadzikama.
04
Corrosion resistance
Muviri weshongwe nemukati memukati wakagadzirwa nezvinhu zvisingadziviriri-zvakadai seFRP, 316L simbi isina simbi) kuti zvimirire nharaunda ine alkaline uye sulfide corrosion.
05
Zvakanakira zvigadzirwa zvekambani yedu
Muchirevo chemitemo yakasimba yezvakatipoteredza, dhizaini yakanatswa yakakosha pakuita kuti kunyura kushande uye kugadzikana kwekushanda. Kambani yedu ine timu yevanyanzvi mainjiniya vane makore anopfuura makumi maviri eruzivo mukucheneswa gasi, vanozivana nemaitiro epamba neekunze akadai seGB, API, ASME, uye EPA. Tinopa dhizaini yakasarudzika zvichienderana neyakagadzirwa gasi (H₂S concentration, CO₂ content), kushandiswa kwesimba, uye kurapwa zvinodiwa, optimizing packing type, liquid-gasi reshiyo, uye shongwe dhayamita kuti kuwedzere kubviswa kweH₂S uku tichideredza kushandiswa kwealkali (kazhinji 0.5-1.2 kg NaOH pakg H₂S yabviswa). Isu tinodzivirira akamisikidzwa matemplate uye tinoitisa yakadzama hydraulic uye mashoma ekutamisa maverengero epurojekiti yega yega kuti ienderane nemamiriro ekushanda.
Kambani yedu inonyatso shandisa iyo ISO9001 mhando manejimendi system mukati mehupenyu hweprojekiti, inovhara dhizaini, kutenga, kugadzira, uye kutumira. Munguva yechikamu chekugadzira, maitiro simulation (uchishandisa Aspen Plus) inosimbisa kunyudza kunyatsoshanda uye kudonha kwekumanikidza; zvakakosha zvikamu (kurongedza, pombi, mavharuvhu) anotariswa zvakanyanya kupinda kuti ave nechokwadi chekuteedzera zvinhu uye maitiro ekuita; kugadzirwa kweshongwe yemutumbi kunotevera kumanikidzwa kwemidziyo (GB 150 kana ASME BPVC), isina-yedzo yekuparadza (UT, RT) yemawelds; kutumwa kunosanganisira 72-awa inoramba ichiedzwa kuti ione kuti H₂S inonyatso kubviswa, kudonha, uye zviratidzo zvekushandisa alkali. Iyi yakarongeka manejimendi inovimbisa kuenderana kwechigadzirwa mhando uye pane-nguva kuendesa.
Isu tinoona kunaka kwechigadzirwa senzira inoraramisa bhizinesi, yakazvipira kuunza-makororo akavimbika epamusoro. Chidzitiro chega chega chinodzorwa nemhando yepamusoro: shongwe muviri inoshandisa ngura{2}}zvinhu zvisingachinjiki zvine hupenyu hwekugadzira Hunopfuura kana kuenzana nemakore gumi nemashanu; kurongedza kunosarudzirwa yakakwira chaiyo nzvimbo uye yakaderera kudonhedza kudonha (senge PP yakarongeka kurongedza nehupenyu hwesevhisi Yakakura kupfuura kana yakaenzana nemakore mashanu); otomatiki kudzora masisitimu (kusanganisira pH metres, kuyerera mita, uye alkali dosing pombi) inovimbisa kushanda kwakagadzikana. Isu tinovimbisa kuti gasi rakacheneswa rinosangana nemiyero yekuburitsa, ine chiyero chefekitori chegumi.
Kushanda zvakanaka mushure me-sevhisi yekutengesa kwakakosha kuti uve nechokwadi chekushanda nguva dzose. Kana tichigamuchira chikumbiro chesevhisi, timu yedu yehunyanzvi inopa mhinduro yekutanga mukati memaawa masere (24/7) kuburikidza nefoni, email, kana vhidhiyo. Pazvinhu zviri kure-zvinogadzirisika (semuenzaniso, kugadzirisa parameter, control system troubleshooting), tinotungamira kugadzirisa mukati memaawa makumi maviri nemana; zve-zvinoda kugadziriswa kwesaiti (semuenzaniso, kutsiva kurongedza, kugadzirisa pombi), mainjiniya anotumirwa mukati memaawa 48 (mumba) kana maawa makumi manomwe nemaviri (yepasirese). Isu tinopawo anogara achigadzirisa masevhisi (semuenzaniso, corrosion yekuongorora, kunyatsoita bvunzo) kuwedzera hupenyu hwemidziyo.
Yedu Caustic Scrubber yeH₂S Removal inozivikanwa zvakanyanya nemabhizinesi anotungamira musimba uye zvikamu zvezvakatipoteredza, seShell, ExxonMobil, Sinopec, uye Veolia, nekuda kwekushanda kwavo kwakanyanya uye kuvimbika mumaindasitiri ekushandisa.
Kambani yedu inogona kupa yakagadziridzwa scrubber masisitimu muchimiro cheturnkey mapurojekiti (kusanganisira dhizaini, kugadzira, kuisirwa, uye kutumira), pamwe nekupa masevhisi ehunyanzvi senge process optimization uye kudzidzira opareta. Kune vatengi vane zvavanoda kwenguva pfupi, tinopawo masevhisi ekurenda kune skid-mamounted scrubbers, tichiita sarudzo dzinochinjika zvichienderana nezvinodiwa zveprojekiti.
