Umgangatho oPhakamileyo waseTshayina weFactory yeGesi yokuLungiselela iGesi yeSkid-PSA decarbonization skid – Rongteng

Inkcazo

I-decarburization yegesi yendalo (i-decarbonization) skid, sisixhobo esiphambili ekuhlanjululweni kwegesi yendalo okanye unyango.

Umxholo wekhabhon diokside kumgangatho womgangatho wegesi yendalo akufanele ube ngaphezu kwe-3%. Kwaye ikharbon diokside emanzini emva kokuba intsimbi inomhlwa owomeleleyo. Ukuba ixabiso le-PH liyafana, i-acidity ratio ye-carbon dioxide nayo iphezulu, ngoko iqondo lokutya kwe-carbon dioxide kwintsimbi nalo liphezulu.

I-Pressure swing adsorption (PSA) yitekhnoloji entsha esetyenziselwa ukwahlula umxube wegesi kwitekhnoloji yokwahlula i-adsorption. Xa kuthelekiswa nendlela yokufunxa imichiza yemveli, iteknoloji ye-PSA inomtsalane ngokwezoqoqosho ukususwa nokubuyiswa kwe-H2S kunye ne-CO2 kwigesi yendalo, kwaye iphuhliswa ngamandla.

Itekhnoloji yokwahlula igesi yePSA ineenzuzo zokusebenza okulula, ukulahleka koxinzelelo oluphantsi, ukuphelelwa ngamanzi emzimbeni ngelixa ususa i-CO2, indawo ephantsi yombethe yegesi ecocekileyo kunye namanzi, kwaye iimveliso zinokuhlangabezana neemfuno zokuthumela ngaphandle kwegesi. I-PSA ingasetyenziselwa ukugxininiswa kwe-CO2 kunye ne-desulfurization ekhethiweyo kwigesi yendalo.

Itshathi equkuqelayo

I-Adsorption yenziwa phantsi koxinzelelo kwaye i-desorption yenziwa phantsi koxinzelelo oluncitshisiweyo. Ngenxa yokuba umjikelo we-adsorption umfutshane kwaye ubushushu be-adsorption abukwazi ukuchithwa ngexesha, bunokusetyenziselwa i-desorption. Ngoko ke, iqondo lokushisa kwibhedi ye-adsorption ebangelwa ukushisa kwe-adsorption kunye nokushisa kwe-desorption kunotshintsho oluncinci, olunokuthi luthathwe njengenkqubo ye-isothermal. Ukusebenza kwebhedi ye-adsorption esisigxina, nokuba yi-adsorption ye-speed swing okanye i-adsorption swing yoxinzelelo, kuba i-adsorbent idinga ukuhlaziywa, i-adsorption iyaphazamiseka. Kwishishini, iibhedi ezimbini okanye ngaphezulu ze-adsorption zisetyenziswa, ukwenzela ukuba i-adsorption kunye nokuvuselelwa kwebhedi ye-adsorption iqhutywe ngokuhlukileyo (okanye ngokujikelezayo), ukuqinisekisa ukuqhubeka kwayo yonke inkqubo ye-adsorption.

Iimpawu ezisebenzayo

Ukusebenza kwe-pressure swing adsorption decarbonization skid yi-90%.I-CO2 inokwahlulwa ngokutshintsha koxinzelelo kunye ne-adsorption yomzimba, ngaphandle kokusabela kweekhemikhali. Ukongeza kokususa i-CO2, iteknoloji ye-PSA isetyenziswa ngokubanzi ekubuyiseni nasekuhlambululeni i-H2, i-CH4, i-CO, i-CO2 kunye nezinye iigesi.
