Nkev Kom Qhuav

Ua kom siv molecular sieve adsorption muaj peev xwm rau cov roj cua kom qhuav thiab ua kom huv huv, yog siv dav hauv cov roj tawm, kev thauj mus los, txhaws thiab lwm yam kev sib txuas.Qhov tiav cov cuab yeej muaj ob txoj haujlwm ua haujlwm ntawm lub chaw tsim hluav taws xob kom qhuav thiab ntau lub rhaub, ua kom lub kiv cua, txias, lim muaj pes tsawg leeg. Ntxiv rau kev ziab kom qhuav ntauwd, kev hloov kho ntauwd yuav tsum muaj kev ua haujlwm hauv tes, tag nrho txhua yam kev ua los ntawm lub cuab yeej ua haujlwm tau, kuj tuaj yeem tsim los kom txhua yam tsis siv neeg.

Wellhead outflow ntawm cov roj ntuj yuav luag txhua qhov roj theem theem dej, thiab txawm nqa qee qhov nqi ntawm cov dej ua kua. Muaj cov dej noo hauv cov roj ntuj feem ntau ua rau muaj kev rau txim loj: cov roj ntuj muaj CO2 thiab H2S ua cov kua qaub nyob rau hauv cov dej thiab corrodes cov raj xa dej thiab khoom siv; tsim cov roj hydrates nyob rau hauv qee yam kev cuam tshuam los thaiv cov li qub, kav dej thiab khoom siv; Txo cov raj xa khoom thauj tau, uas ua rau kev siv lub zog tsis tsim nyog. Qhov muaj cov dej noo nyob ntawm qhov muaj cov roj ntuj yog qhov tsis zoo heev, yog li qhov xav tau lub cev qhuav dej yog qhov nruj dua.

Hauv kev ua cov pa nkev, lub cev qhuav dej, cov txheej txheem desulfurization tuaj yeem siv cov qauv adsorption. Tshwj xeeb tshaj yog adsorption lub cev qhuav dej, vim nws qhov tob tob hauv dej siab, cov khoom siv tau yooj yim, hneev me me thiab lwm yam.

Kev ua haujlwm ntawm cov adsorbent yog qhov tseem ceeb heev rau kev ua haujlwm adsorption. Cov khoom lag luam adsorbents yuav tsum ua kom tau raws li qhov yuav tsum tau ua dhau los: Cov xaiv siab, qhov loj ntawm sab hauv thaj chaw, siab adsorption kev ua si, qee yam khoom siv lub zog thiab lub cev muaj zog, tshuaj zoo tsis ua hauj lwm, thermal stability Raws li pheej yig thiab yooj yim heev.

Cov nkev nkev feem ntau siv hauv cov adsorbent: silica gel, qhib alumina, qhib bauxite thiab molecular sab cib.
