Ennyonnyola y'ebintu
Ekisiimuula ekiwunya (caustic scrubber) eky’okuggyawo H2S (era ekimanyiddwa nga alkaline H2S scrubber) kye kyuma ekirongoosa ggaasi nga kyesigamiziddwa ku nkola z’okunyiga eddagala.
Omusingi gwayo omukulu kwe kuleeta ggaasi erimu H2S-okukwatagana mu bujjuvu n’ekisengejjero ekiwunya (sodium hydroxide oba potassium hydroxide) mu munaala ogupakiddwa oba ogwa tray, nga H2S ekwatagana ne alkali okukola sodium sulfide (Na2S) oba sodium hydrosulfide (NaHS) atabulwa, bwe kityo n’eggyawo H2S mu ggaasi.
Kisobola okukendeeza mu ngeri ennywevu obungi bwa H2S okutuuka wansi wa 10 ppm, okukakasa obukuumi bw’ebyuma ebiri wansi w’omugga n’okugoberera obutonde bw’ensi.
Omusingi gw’okukola
Enkola y’okukola ey’okuggyawo Scavenger H2s esobola okufunzibwa ng’emitendera etaano emikulu: okulongoosa ggaasi nga tennabaawo → okuddamu okunyiga → okutambula kw’ekisengejjero → okulongoosa ekisengejjero ekimaze → okufulumya ggaasi erongooseddwa
Okusooka okulongoosa ggaasi:Gaasi erimu H2S- (nga ggaasi ow’obutonde omubisi oba ekyuma ekirongoosa off-ggaasi) asooka kuyingira mu ngoma ekoona okuggyawo amatondo g’amazzi n’obutundutundu obukalu (okwewala okuziyiza okupakinga kw’ekisiimuula n’okukosa obulungi bw’okunyiga).
Enkola y’okunyiga:Omukka ogulongooseddwa nga tegunnabaawo guyingira wansi w’omunaala gw’okusiimuula n’akulukuta waggulu, ate ekisengejjero ekiwunya (2-10% NaOH) ne kifuuyirwa wansi okuva waggulu. Mu kitanda ekipakiddwa (ekijjudde okupakiddwa okutegekeddwa oba okutali kwa bulijjo), ggaasi n’amazzi bijja mu kukwatagana okw’okumpi, era H2S bikwatagana ne NaOH: H2S + 2NaOH → Na2S + 2H2O (oba H2S + NaOH → NaHS + H2O, okusinziira ku bungi bwa alkali).
Entambula y’ekigonjoola:Ekizimbulukusa ekiyitibwa caustic solution, oluvannyuma lw’okunyiga H2S, kikung’aanya wansi w’omunaala ne kiyisibwa ne kidda waggulu okuddamu okukozesebwa. Ekitundu ky’ekisengejjero ekikozesebwa kifulumizibwa buli kiseera okukuuma ekisengejjo kya alkali mu mazzi agatambula (ekitera okufugibwa waggulu wa 2%).
Obujjanjabi bwa solution ezisaasaanyiziddwa:Ekisengejjero ekimaze okukozesebwa (ekirimu Na2S/NaHS) kisindikibwa mu nkola ya neutralization oba regeneration. Kiyinza okulongoosebwa n’ebirungo ebiziyiza okuzimba (nga haidrojeni perokisayidi) okukola ebirungo bya salufa ebitali bya bulabe, oba okuddamu okutondebwa nga tukozesa lime okuzzaawo alkali okuddamu okukozesebwa.
Omukka ogufuluma mu ggaasi erongooseddwa:H2S-eggyawo ggaasi efuluma waggulu ku munaala, eyita mu kifo ekiggya enfuufu okuggyawo amatondo g’amazzi agayingiziddwa, n’oluvannyuma n’etwalibwa mu nkola eziri wansi oba n’efulumizibwa oluvannyuma lw’okutuukiriza omutindo.
Caustic Scrubber for H2S Okuggyawo Ebintu Ebikulu
Obulung’amu bwa waggulu mu kuggyawo
Asobola okukendeeza mu ngeri ennywevu obungi bwa H2S okuva ku nkumi n’enkumi za ppm okutuuka wansi wa 10 ppm, ng’obulungi bw’okuggyawo Businga oba obwenkana 99%, nga butuukana n’omutindo omukakali ogw’okufulumya omukka oguva mu butonde (nga Less than oba equal to 20 ppm for industrial emissions).
01
Obusobozi obugazi
Obusobozi bw’okulongoosa yuniti emu buva ku 100 Nm3/h okutuuka ku 50,000 Nm3/h, nga busaanira emigga gya ggaasi emitono-(ebifo ebikola ggaasi ow’obutonde) okutuuka ku binene-(ebifo ebirongoosa ggaasi ow’obutonde).
02
Okuddamu amangu
Enkola y’okunyiga eba ya mangu, esobozesa enkola eno okukwatagana amangu n’enkyukakyuka mu bungi bwa H2S eziyingira (mu ddakiika 10-30 okutebenkera).
03
Okukola okwangu
Enkola eno nnyangu okufuga, nga erina ebipimo ebikulu (obungi bwa alkali, omugerageranyo gw’amazzi-ggaasi) ebitereezebwa okuyita mu nkola za otomatiki okukuuma omulimu ogutebenkedde.
04
Okuziyiza okukulukuta
Omubiri gw’omunaala n’ebitundu eby’omunda bikolebwa mu bintu ebigumira okukulukuta-(nga FRP, ekyuma ekitali kizimbulukuse ekya 316L) okusobola okugumira embeera ya alkaline n’okukulukuta kwa sulfide.

Ebirungi ebiri mu bintu bya kkampuni yaffe
Mu mbeera y’amateeka amakakali agakwata ku butonde bw’ensi, dizayini erongooseddwa kikulu nnyo okulaba ng’okunyiga kukwata bulungi n’okutebenkera kw’emirimu. Kkampuni yaffe erina ttiimu ya bayinginiya abakugu abalina obumanyirivu obw’emyaka egisukka mu 20 mu kulongoosa ggaasi, nga bamanyi omutindo gw’omunda n’ebweru nga GB, API, ASME, ne EPA. Tuwa dizayini erongooseddwa okusinziira ku butonde bwa ggaasi (H2S concentration, CO2 content), puleesa y’okukola, n’ebyetaago by’okulongoosa, okulongoosa ekika ky’okupakinga, amazzi-omugerageranyo gwa ggaasi, ne diameter y’omunaala okusobola okutumbula H2S okuggyawo ate nga tukendeeza ku nkozesa ya alkali (mu ngeri entuufu 0.5-1.2 kg NaOH buli kg H2S eggiddwawo). Twewala ebikozesebwa ebituufu era tukola okubalirira okukwata ku mazzi n’okutambuza amasasi mu bujjuvu ku buli pulojekiti okukwatagana n’embeera z’emirimu ezenjawulo.
Kkampuni yaffe essa mu nkola nnyo enkola y’okuddukanya omutindo eya ISO9001 mu bulamu bwa pulojekiti yonna, ng’ekwata ku dizayini, okugula, okukola, n’okutandika okukola. Mu kiseera ky’omutendera gw’okukola dizayini, okusiiga enkola (nga tukozesa Aspen Plus) kukakasa obulungi bw’okunyiga n’okukka kwa puleesa; ebitundu ebikulu (okupakinga, ppampu, vvaalu) biyita mu kwekebejjebwa okukakali okuyingira okukakasa nti bigoberera omutindo gw’ebintu n’omutindo gw’emirimu; okukola omubiri gw’omunaala kugoberera omutindo gw’ekibya kya puleesa (GB 150 oba ASME BPVC), nga waliwo okugezesa okutali-okusaanyaawo (UT, RT) ku welds; okutandika okukola mulimu okugezesa okukola obutasalako okumala essaawa 72-okukakasa obulungi bw’okuggyawo H2S, okukka kwa puleesa, n’ebiraga enkozesa ya alkali. Enzirukanya eno entegeke ekakasa omutindo gw’ebintu ogutakyukakyuka n’okubituusa mu budde.
Tutwala omutindo gw’ebintu ng’obulamu bw’ekitongole, nga twewaddeyo okutuusa ebisenya eby’okwesigamizibwa ebya waggulu-. Buli kyuma kiyita mu kulondoola omutindo mu ngeri enkakali: omubiri gw’omunaala gukozesa ebintu ebigumira okukulukuta-nga obulamu bwa dizayini busukka oba obwenkana emyaka 15; okupakinga kulondebwa olw’obuwanvu obw’enjawulo obw’okungulu n’okugwa kwa puleesa entono (nga okupakinga okutegekeddwa mu PP nga kulina obulamu bw’obuweereza obusinga oba obwenkana emyaka 5); enkola ezifuga mu ngeri ey’obwengula (omuli mita za pH, mita z’okukulukuta, ne ppampu ezigaba eddagala lya alkali) zikakasa nti zikola bulungi. Tukakasa nti ggaasi erongooseddwa etuukana n’omutindo gw’okufulumya omukka, ng’omuwendo gw’ebisaanyizo by’ekkolero guli 100%.
Empeereza ennungi oluvannyuma lw'okutunda -kikulu nnyo okukakasa nti ekola obutasalako. Bwe tufuna okusaba kw’empeereza, ttiimu yaffe ey’ekikugu etuwa endowooza ezisooka mu ssaawa 8 (24/7) ng’eyita ku ssimu, email, oba vidiyo. Ku nsonga ezigonjoolwa okuva ewala- (okugeza, okutereeza parameter, okugonjoola ebizibu by'enkola y'okufuga), tulungamya okugonjoola mu ssaawa 24; ku -obwetaavu bw’okuddaabiriza mu kifo (okugeza, okukyusa okupakinga, okuddaabiriza ppampu), bayinginiya basindikibwa mu ssaawa 48 (ez’omunda) oba essaawa 72 (ez’ensi yonna). Tuwa n’empeereza y’okuddaabiriza buli kiseera (okugeza, okwekenneenya okukulukuta, okugezesa obulungi) okwongera ku bulamu bw’ebyuma.
Caustic Scrubber yaffe ey’okuggyawo H2S emanyiddwa nnyo ebitongole ebikulembedde mu by’amasannyalaze n’obutonde bw’ensi, nga Shell, ExxonMobil, Sinopec, ne Veolia, olw’obulungi bwayo obw’amaanyi n’okwesigamizibwa mu mirimu gy’amakolero.
Kkampuni yaffe esobola okuwa enkola za scrubber ezikoleddwa ku mutindo mu ngeri ya pulojekiti ez’ekisumuluzo (omuli okukola dizayini, okukola, okuteeka, n’okutandika okukola), wamu n’okuwa obuweereza obw’ekikugu nga okulongoosa enkola n’okutendeka abaddukanya emirimu. Ku bakasitoma abalina obwetaavu obw’ekiseera, era tuwa obuweereza bw’okupangisa ku skid-mounted scrubbers, okwanguyiza okulonda okukyukakyuka okusinziira ku byetaago bya pulojekiti.
