Warshada fuuq-baxa Molecular Sieve ee Tayada Sare leh - Skid macaanaynta gaasta dabiiciga ah - Rongteng

Hordhac

Desulfurization gaaska dabiiciga ah ee MDEA (desulfurization) skid, oo sidoo kale loo yaqaan MDEA macaanaynta skid iyo unugga gaasta dabiiciga ah, waa aalad muhiim u ah nadiifinta gaaska dabiiciga ah ama qaboojinta gaaska dabiiciga ah.

Unugga ka saarista gaaska dabiiciga ah ee MDEA had iyo jeer waa la qaataa marka baaruudka kaarboon ee gaaska quudinta uu aad u sarreeyo, iyo marka xulashada H₂S ayaa loo baahan yahay si loo helo gaaska aashitada ee ku habboon habaynta warshadda Claus, iyo xaalado kale oo la dooran karo si meesha looga saaro H₂S; Marka meesha laga saarayo H₂S iyo ka saarida xaddi badan oo CO₂, MDEA waxaa loo isticmaali karaa sida habka aminka isku dhafan;

Waqtigan xaadirka ah, teknoolojiyadda desulfurization ugu weyn ee loo isticmaalo wax soo saarka warshadaha ee guriga iyo dibadda waa: qalalan (jirka) desulfurization, desulfurization noolaha iyo desulfurization qoyan.

Sulfuraynta qoyan waxaa ka mid ah habka nuugista iyo habka oksaydhka qoyan. Habka nuugista kiimikaad, oo uu matalo nuugista amine alkohol, ayaa si weyn loogu isticmaalay warshadaha. Hydrogen sulfide ku jirta gaaska waxaa loo wareejiyaa wejiga dareeraha ah si loo nadiifiyo gaaska.

Farsamada nadiifinta

Tiknoolajiyada desulfurization bayooloji, oo ku jirta xaalada micro oxygen, waxay u rogi kartaa hydrogen sulfide galay baaruud elemental, laakiin tignoolajiyada desulfurization noolaha ma aha qaan hadda.

Tiknoolajiyada qallalan ee qallalan waxaa ka mid ah habka oksaydhka birta, habka kaarboonka firfircoon, habka shaandhada molecular, habka beddelka ion, habka kala soocida xuubka, habka biochemical, iwm hadda, tignoolajiyada PSA qalalan ayaa ah tan ugu ballaaran ee loo isticmaalo daawaynta gaasta dabiiciga ah ee yar-yar ee warshadaha, taas oo si buuxda u kombuyutarka gacanta ku haysa, hawlgalka tooska ah, iyo ka saarida si toos ah munaaradda qaladka, si ay u shaqeyso muddo dheer.

hababka desulfurization

Amorphous iron hydroxide (habka qalalan). Astaamaha: waxay leedahay sifooyinka saxda ah ee desulfurization sare, awoodda baaruudda sare, xoog wanaagsan iyo feejignaan la'aan. Waxaa si weyn loo isticmaalaa in laga saaro hydrogen sulfide ee gaaska dabiiciga ah, gaaska synthetic, biogas, gaaska dhuxusha, methane dhuxusha iyo walxo kala duwan oo kiimiko ah oo baaruud ku jira; Desulfurization The amorphous hydroxyl oxidation waa desulfurization falcelinta, kaas oo aan xakamayn karin qoto dheer desulfurization ah. Waa geeddi-socod nadiifin ah oo wanaagsan. Iyada oo saturation of desulfurizer iyo lays of munaaradda desulfurization, saamaynta desulfurization si weyn hoos u dhigi doonaa, iyo content ee hydrogen sulfide ee gaaska dabiiciga ah sifaysan si degdeg ah u kici doonaa, sidaas darteed waxaa lagama maarmaan ah in la beddelo desulfurizer ah waqtiga.
