Umgangatho oPhakamileyo waseTshayina weSkid eFactory yeZityalo ze-LNG-140 TPD isityalo esikhulu sokunyibilikisa se-LNG-eRongteng

Inkcazo yenkqubo nganye

Ukwahlula ukuhluzwa kwegesi yokutya kunye neyunithi yokulawula uxinzelelo

1）Inkcazo yenkqubo

Irhasi yendalo yomxhesho osuka kumntla uqukuqela ngombhobho ngoxinzelelo lwe-5.0 ~ 6.0MpaG ingena kwi-fid gas inlet filter separator emva kokulawula uxinzelelo, kwaye ingena kwinkqubo esezantsi emva kokwahlulwa kunye nokulinganisa.

Isixhobo esiphambili senkqubo sisihluli segesi yokutya, i-flowmeter, isilawuli soxinzelelo, njl.

2) Iiparamitha zoyilo

Ukucutshungulwa kwamandla: 20×10⁴Nm³/usuku

Uluhlu lohlengahlengiso: 50% ~ 110%

Inkqubo yonyango lwangaphambili

Iyunithi yokuphelisa igesi yokutya

1）Inkcazo yenkqubo

Igesi yokutya evela phezulu ingena kwiyunithi yegesi ye-deacidification, esebenzisa isisombululo se-MDEA ukususa iigesi ze-asidi ezifana ne-CO.₂kunye noH₂S kwigesi yokutya.

Irhasi yendalo ingena ukusuka kwindawo esezantsi ye-absorbeer (inqaba yokufunxa) kwaye idlula kwi-absorber ukusuka ezantsi ukuya phezulu; Isisombululo se-MDEA esihlaziywe ngokupheleleyo (isisombululo esincinci) singena ukusuka kwindawo ephezulu ye-absorber kwaye sidlula kwi-absorber ukusuka phezulu ukuya phezulu. Isisombululo se-MDEA se-reverse flow kunye negesi yendalo idibene ngokupheleleyo kwi-absorber, i-CO₂kwigesi ifunnwe kwaye ingena kwisigaba solwelo, kwaye amacandelo angaxutywanga aholwa aphume phezulu kwi-absorber kwaye angene kwi-cooler yegesi ye-decarbonization kunye ne-separator. Igesi evela kwisahluli segesi ye-decarbonization ingena kwiyunithi yokususa i-mercury yegesi yokutya, kwaye i-condensate iya kwi-flash tank.

Umxholo weCO₂kwigesi yendalo enyangweyo ingaphantsi kwe-50ppmv.

Isisombululo se-MDEA esifunxa i-CO₂ibizwa ngokuba yisisombululo esityebileyo, esithunyelwa kwinqaba ye-flash, kwaye igesi yendalo edanyazwe yi-depressurization ithunyelwa kwinkqubo yamafutha. Emva kokutshintshiselana kobushushu phakathi kwe-flash ecebileyo yolwelo kunye nesisombululo (ulwelo oluthambileyo) oluphuma ezantsi kwinqaba yokuhlaziya, phakamisa ubushushu ukuya kwi- ~ 98 ℃ ukuya kwindawo ephezulu yenqaba yokuhlaziya, kwaye uqhubele phambili ukuhluba ngokutsha kwinqaba yokuhlaziya de idigri ebhityileyo yolwelo olubhityileyo lufikelele kwisalathiso.

Ulwelo olubhityileyo oluphuma kwinqaba yohlaziyo ludlula kwisitshintshi sobushushu solwelo olutyebileyo noluhlwempuzekileyo kunye nesipholileyo solwelo olubhityileyo. Ulwelo olubhityileyo lupholisiwe ukuya ku- ~ 40 ℃, lucinezelwe yimpompo yolwelo ebhityileyo kwaye lungena lusuka kwindawo ephezulu yenqaba yokufunxa.

I-gas ephumayo phezulu kwinqaba yokuvuselela ingena kwi-asidi ye-gas separator ngokusebenzisa i-acid gas cooler, i-gas esuka kwi-asidi ye-gas separator ithunyelwa kwinkqubo yokukhutshwa kwegesi ye-asidi, kwaye i-condensate ithunyelwa kwi-flash separator emva koxinzelelo lwempompo yokubuyisela.

Umthombo wobushushu we-reboiler ye-regeneration tower ufudumeza ngeoli yokudlulisa ubushushu. Izixhobo eziphambili zenkqubo yale yunithi yinqaba yokufunxa kunye nenqaba yokuvuselela.
