Isihluzo se-molecular desulphurization skid

Umgaqo

I-molecular sieve desulphurization (desulfurization) skid, ekwabizwa ngokuba yi-molecular sieve sweeting skid, sisixhobo esibalulekileyo ekuhlanjululeni igesi yendalo okanye ekulungiseni igesi yendalo. I-molecular sieve yikristale ye-alkali metal aluminosilicate enesakhiwo sesakhelo kunye nesakhiwo esifanayo se-microporous. Xa igesi yokutya equlethe amanzi amdaka idlula kwi-molecular sieve bed kubushushu begumbi, amanzi amdaka kunye ne-mercaptan ziyafunxwa, ngaloo ndlela kunciphisa amanzi kunye nomxholo we-mercaptan kwi-feed gas, kufezekiswa injongo yokuphelelwa ngamanzi emzimbeni kunye nokususwa kwe-sulfurization. Inkqubo yokufakwa kwe-molecular sieve ibandakanya ukuxinana kwe-capillary kunye nokuxutywa ngokomzimba okubangelwa ngamandla e-van der Waals. Kwi-equation kaKelvin, kunokubonwa ukuba ukuxinana kwe-capillary kuyabuthathaka ngokunyuka kobushushu, ngelixa ukuxutywa ngokomzimba kuyinkqubo ye-exothermic, kwaye ukuxutywa kwayo kuyabuthathaka ngokunyuka kobushushu kwaye kwanda ngokunyuka koxinzelelo; ke ngoko, inkqubo yokufakwa kwe-molecular sieve idla ngokuqhutywa kubushushu obuphantsi kunye noxinzelelo oluphezulu, ngelixa ukuvuselelwa kwe-desorption kwenziwa kubushushu obuphezulu kunye noxinzelelo oluphantsi. Phantsi kwesenzo segesi yokuvuselela ubushushu obuphezulu, ecocekileyo nephantsi koxinzelelo, i-molecular see adsorbent ikhupha i-adsorbate kwi-micropore iye kwi-regeneration gas flow de inani le-adsorbate kwi-adsorbent lifikelele kwinqanaba eliphantsi kakhulu, kwaye linamandla okufunxa amanzi kunye ne-mercaptan kwi-feed gas, lifezekisa inkqubo yokuvuselela kunye nokurisayikilisha ye-molecular see.

Inkqubo yetekhnoloji

Inkqubo yokuhamba kwegesi yendalo ye-molecular sieve desulphurization (desulfurization) skid iboniswe kumzobo. Le yunithi isebenzisa iinkqubo ezintathu ze-tower, i-tower adsorption enye, i-tower regeneration enye kunye ne-tower cooling enye. Emva kokususa ulwelo lwe-hydrocarbon olufakwe ngaphakathi ngesihluzi se-feed gas separator, i-feed gas ingena kwi-molecular sieve desulfurization tower. Amanzi kunye ne-mercaptan kwi-feed gas zifunxwa yi-molecular sieve ukuze kufezekiswe inkqubo yokuphelelwa ngamanzi emzimbeni kunye ne-mercaptan adsorption. Igesi ecocekileyo evela ekuphelelweni ngamanzi emzimbeni kunye nokususwa kwe-mercaptan ingena kwi-product gas dust filter ukuze kususwe uthuli lwe-molecular sieve, kwaye emva koko ithunyelwa ngaphandle njengegesi yemveliso.

Ii-molecular seeves kufuneka zivuselelwe emva kokufunxa amanzi athile kunye ne-mercaptan. Emva kokucoca uthuli lwegesi yemveliso, inxalenye yegesi yemveliso ikhutshwa njengegesi yokuvuselela. Emva kokuba igesi ifudunyezwe ukuya kuma-300 ℃ yi-furnace yokufudumeza, inqaba ifudunyezwa kancinci ukuya kuma-272 ℃ nge-molecular seeve desulfurization tower egqibe inkqubo yokufunxa ukusuka ezantsi ukuya phezulu, ukuze amanzi kunye ne-mercaptan efakwe kwi-molecular seeve zikwazi ukwahlulwa kwaye zibe yigesi yokuvuselela etyebileyo ukuze kugqitywe inkqubo yokuvuselela.
