Cov khoom noj khoom haus: roj synthesis, roj av, roj av ntuj, roj thee. Nws tuaj yeem kho cov pa roj nrog cov inorganic sulfur siab
ua 23g/m3 nrog qib kev ntxuav kom zoo. Nws kuj tseem tuaj yeem ntxuav cov pa roj nrog txog li 20mg/m3 ntawm cov yooj yim dua no
Cov organic sulfur ua COS kom tsawg dua 0.1 ppm.
5. Thauj khoom
Qhov tob ntawm kev thauj khoom: Pom zoo kom muaj L/D siab dua (min3). Kev teeb tsa ob lub reactors hauv series tuaj yeem txhim kho kev siv
kev ua haujlwm ntawm cov adsorbent.
Cov txheej txheem thauj khoom:
(1) Ntxuav lub reactor ua ntej loading;
(2) Muab ob daim hlau stainless grids nrog mesh me dua li cov adsorbent;
(3) Muab ib txheej 100 hli ntawm Φ10—20 hli refractory spheres rau ntawm cov stainless grids;
(4) Siv cov tshuaj nqus kom tshem tawm cov hmoov av;
(5) Siv cov cuab yeej tshwj xeeb los xyuas kom meej tias cov adsorbent faib sib npaug zos hauv txaj;
(6) Tshawb xyuas qhov sib npaug ntawm lub txaj thaum lub sijhawm thauj khoom. Thaum xav tau kev ua haujlwm sab hauv-reactor, Ib daim ntoo yuav tsum muab tso rau ntawm lub adsorbent rau tus neeg teb xov tooj sawv ntsug.
(7) Nruab ib lub stainless grid nrog mesh me dua li cov adsorbent thiab ib txheej 100mm ntawm Φ20—30mm refractory spheres rau sab saum toj ntawm lub txaj adsorbent kom tiv thaiv kev nkag mus ntawm cov adsorbent thiab xyuas kom meej
txawm tias faib cov roj ntws.
6. Pib ua lag luam
(1) Hloov lub kaw lus los ntawm nitrogen lossis lwm yam roj inert kom txog thaum cov pa oxygen hauv cov roj tsawg dua 0.5%;
(2) Ua kom cov dej ntws los ntawm nitrogen lossis cov roj pub ua ntej kom sov hauv qab qhov siab lossis siab;
