Yakakwira Hunhu China H2S Kubviswa Kubva kuMafekitori eGasi Rakasikwa - PSA decarbonization skid yekuchenesa gasi rechisikiro - Rongteng

Tsanangudzo

Natural gasi decarburization (decarbonization) skid, chinhu chakakosha mukuchenesa gasi kana kurapwa.

Izvo zvirimo zvekabhoni dhaidhi mugasi rechisikigo mhando chiyero hachifanirwe kupfuura 3%. Uye carbon dioxide mumvura mushure mokunge simbi yave nekuora kwakasimba zvikuru. Kana iyo PH kukosha kwakafanana, acidity reshiyo yekabhoni dhaikisaidhi yakakwirawo, saka dhigirii rekuora kwekabhoni dhaokisaidhi pasimbi zvakare yakakwirira.

Pressure swing adsorption (PSA) tekinoroji nyowani inoshandiswa kupatsanura gasi musanganiswa mune adsorption yekuparadzanisa tekinoroji. Kana ichienzaniswa neyechinyakare makemikari absorption nzira, PSA tekinoroji inokwezva mune zvehupfumi pakubvisa uye kudzoreredza kweH2S neCO2 kubva mugasi rechisikigo, uye iri kuvandudzwa zvine simba.

PSA gasi kupatsanura tekinoroji ine zvakanakira kushanda kuri nyore, kuderera kwekumanikidza kurasikirwa, kupera simba kwemvura paunenge uchibvisa CO2, yakaderera dova gasi rakacheneswa nemvura, uye zvigadzirwa zvinogona kusangana nezvinodiwa zvegasi kunze kwenyika. PSA inogona kushandiswa ku CO2 kusungwa uye kusarudza desulfurization mugasi rechisikigo.

Kuyerera chati

Adsorption yakaitwa pasi pekumanikidzwa uye desorption yakaitwa pasi pekumanikidzwa kwakaderedzwa. Nekuti iyo adsorption cycle ipfupi uye adsorption kupisa haigone kubviswa nekufamba kwenguva, inogona kushandiswa kuita desorption. Nokudaro, kutonhora kwemubhedha wekushambadza kunokonzerwa nekupisa kwekupisa uye kupisa kwekupisa kune shanduko shoma, iyo inogona kuonekwa seyo isothermal process. Single fixed adsorption bed operation, ingave tembiricha swing adsorption kana pressure swing adsorption, nekuti iyo adsorbent inoda kuvandudzwa, iyo adsorption inopindirana. Muindasitiri, mabhedha maviri kana anopfuura adsorption anoshandiswa, kuitira kuti adsorption uye kuvandudzwa kwemubhedha weadsorption zviitwe neimwe nzira (kana kutenderera kutenderera), kuve nechokwadi kuenderera kweiyo adsorption process yese.

Zvishandiso zvinoshanda

Kushanda kwepressure swing adsorption decarbonization skid ndeye 90%.CO2 inogona kupatsanurwa nekuchinja kwekumanikidza uye kushambadza kwemuviri, pasina kuita kwemakemikari. Pamusoro pekubvisa CO2, tekinoroji yePSA inoshandiswa zvakanyanya mukudzoreredza nekucheneswa kweH2, CH4, CO, CO2 nemamwe magasi.
