Tsananguro
Kubvisa kabhoni mugasi rechisikigo (decarbonization) skid, chishandiso chakakosha mukuchenesa kana kurapa gasi rechisikigo. PSA itekinoroji yekubvisa kabhoni ine simba shoma inoita kuti CO2 ikwanise kunyudzwa uye kunyudzwa nekuchinja kumanikidzwa kwekushanda. Iyi tekinoroji inowanzo nyudzwa uye kupatsanura CO2 kubva kugasi rechisikigo pa pressure yekushanda ye 0.5 ~ 1MPa, uye yozobva yanyudzwa ne vacuum desorption kuti ipedzise kugadzwazve kwe adsorbent. Nzira yePSA ndeye physical adsorption, kunyangwe ichienzaniswa ne chemical adsorption, kugona kwayo kunyudzwa kwakaderera uye kusarudza kwayo kwakaderera; Zvisinei, kufamba kwePSA kuri nyore, adsorbent ine hupenyu hwakareba hwebasa, iri nyore kugadzwazve, uye inoshandisa simba shoma. Panguva imwe chete, inewo zvakanakira zvakaita se automation yakawanda, mabhenefiti akanaka ezvakatipoteredza, uye kushanda kwakawanda. Kunyanya kana uchibata ne high-pressure feed gas, kazhinji hapana chikonzero chekuidzvanya zvakare. Nzira yePSA inogona kushandiswa patembiricha yemumba pasina chikonzero chekudziisa nekutonhodza, zvichichengetedza simba rinoshandiswa ka1-2 kana tichienzanisa nenzira yeTSA; Uyezve, kana tichienzanisa nenzira yakaenzana yeTSA, nzira yePSA inoda dose shoma ye adsorption.
Hunhu hwekabhoni dhayokisaidhi mugasi rechisikigo hahufanirwe kupfuura 3%. Uye kabhoni dhayokisaidhi mumvura mushure mesimbi ine ngura yakasimba. Kana PH yakaenzana, chiyero cheacidity chekabhoni dhayokisaidhi chakakwirawo, saka mwero wekuora kwekabhoni dhayokisaidhi pasimbi wakakwirawo.
Kudzvinyirirwa kwemhepo nemhepo (Pressure swing adsorption - PSA) itekinoroji itsva inoshandiswa kupatsanura musanganiswa wegesi mutekinoroji yekuparadzanisa mhepo nemhepo. Kana tichienzanisa nenzira yechinyakare yekunyudza makemikari, tekinoroji yePSA inokwezva hupfumi pakubvisa nekudzoreredza H2S neCO2 kubva mugasi rechisikigo, uye iri kugadzirwa nesimba.
Tekinoroji yekuparadzanisa gasi rePSA ine zvakanakira zvekushanda zviri nyore, kurasikirwa nedzvinyiriro shoma, kupera mvura mumuviri uku uchibvisa CO2, poindi shoma yedova regasi rakacheneswa nemvura, uye zvigadzirwa zvinogona kusangana nezvinodiwa zvekutengeswa kwegasi kunze kwenyika. PSA inogona kushandiswa pakuwanda kweCO2 uye kubvisa sulfurization yakasarudzwa mugasi rechisikigo.
Chati yekuyerera
Kunyudza kwakaitwa pasi pekumanikidzwa uye kunyudza kwakaitwa pasi pekumanikidzwa kwakaderera. Nekuti kutenderera kwekunyudza kupfupi uye kupisa kwekunyudza hakugone kupera nenguva, kunogona kushandiswa pakunyudza. Naizvozvo, tembiricha yemubhedha wekunyudza inokonzerwa nekupisa kwekunyudza uye kupisa kwekunyudza haina shanduko yakawanda, iyo inogona kuonekwa senzira ye isothermal. Kushanda kwemubhedha wekunyudza kwakagadzika kamwe chete, kungave kunyudza kwekushisa kana kunyudza kwe pressure swing, nekuti adsorbent inoda kudzokororwa, kunyudza kunoitika nguva nenguva. Muindasitiri, mibhedha miviri kana kupfuura yekunyudza inoshandiswa, kuitira kuti kunyudza nekudzokororwa kwemubhedha wekunyudza kuitwe nenzira dzakasiyana (kana kuti kutenderera), kuti ive nechokwadi chekuti maitiro ese ekunyudza anoramba aripo.
Zvinhu zvinoshanda
Kushanda zvakanaka kwe pressure swing adsorption decarbonization skid ndeye 90%. CO2 inogona kupatsanurwa nekuchinja kwe pressure uye physical adsorption, pasina chemical reaction. Pamusoro pekubvisa CO2, tekinoroji yePSA inoshandiswa zvakanyanya mukudzoreredza nekuchenesa H2, CH4, CO, CO2 nedzimwe magasi.
