4. IMeko yokuSebenza eqhelekileyo
I-Feedstock: irhasi ye-synthesis, irhasi yentsimi yeoli, igesi yendalo, irhasi yamalahle.Inokuphatha umjelo werhasi ngesulfure engaphiliyo iphezulu
njenge-23g/m3 eneqondo lokucoca eyonelisayo.Isenokucoca umjelo werhasi ukuya kuthi ga kwi-20mg/m3 yelula ngolo hlobo
sulphur ephilayo njenge-COS ukuya ngaphantsi kwe-0.1ppm.
5.Ilayisha
Ukulayisha ubunzulu: I-L/D ephezulu (min3) iyacetyiswa.Ulungelelwaniso lweereactor ezimbini kuthotho kunokuphucula ukusetyenziswa
ukusebenza kakuhle kwe-adsorbent.
Ilayisha inkqubo:
(1)Coca i-reactor phambi kokulayisha;
(2)Beka iigridi ezimbini ezingenakutyiwa ezinobukhulu obuncinci bemesh kune-adsorbent;
(3)Layisha umaleko oyi-100mm we-Φ10—20mm iisphere ezizii-refractory kwiigridi ezingenasici;
(4)Jonga i-adsorbent ukususa uthuli;
(5)Sebenzisa isixhobo esikhethekileyo ukuqinisekisa ukuhanjiswa ngokulinganayo kwe-adsorbent ebhedini;
(6)Hlola ukufana kwebhedi ngexesha lokulayisha.Xa kufuneka umsebenzi wangaphakathi wereactor, ipleyiti yomthi kufuneka ibekwe kwi-adsorbent ukuze umqhubi ame phezu kwayo.
