Tuam Tshoj Natural Gas Conditioning Equipment Hoobkas - Tail Gas kho Skid - Rongteng

Kev piav qhia

Cov pa roj carbon monoxide kho skid feem ntau yog siv los cuam tshuam nrog cov pa roj av ntawm cov khoom siv hluav taws xob rov qab, nrog rau cov pa khib nyiab ntawm cov kua sulfur pas dej thiab TEG pov tseg roj ntawm lub cev qhuav dej ntawm cov khoom siv tshuaj sulfur.
Kev tsim thiab kev ua tau zoo ntawm txoj hlua khi yog sib npaug nrog cov khoom siv hluav taws xob rov qab thiab lub cev qhuav dej.
Natural gas tail gas kho skid tuaj yeem muab faib ua plaub pawg

1. Txo thiab nqus cov txheej txheem
Lub hauv paus ntsiab lus ntawm kev txo qis thiab nqus cov txheej txheem yog tias tus Tsov tus tw roj yog hydrogenated, cov sulfur-muaj cov khoom nyob rau hauv tus Tsov tus tw roj yog txo mus rau H2S, cov generated H2S yog xaiv absorbed los ntawm amine txoj kev, thiab thaum kawg lub regeneration los yog roj yog muab rho tawm mus rau hauv Claus unit rau circulating cov tshuaj tiv thaiv. Cov txheej txheem Hydrogenation muaj kev nqis peev ntau thiab cov nqi ua haujlwm siab, tab sis nws tau siv dav hauv cov tebchaws thiab cheeb tsam uas muaj kev tiv thaiv ib puag ncig siab vim tias nws tuaj yeem ua tiav cov txiaj ntsig zoo, xws li ntau dua 99.8%.

2 txheej txheem oxidation absorption
Oxidation absorption method yog ib txoj hauv kev uas ua ntej oxidizes sulfide hauv tail gas rau SO2, ces absorbs SO2 nrog tov (los yog hnyav), thiab thaum kawg rov qab nws nyob rau hauv daim ntawv ntawm sulfate, sulfide thiab SO2.
Muaj ntau txoj hauv kev uas yog hom no, feem ntau yog siv rau flue gas desulfurization los yog kev kho tus Tsov tus tw roj los ntawm smelters thiab sulfuric acid nroj tsuag, thiab Wellman Tswv txoj kev yog siv rau Claus Tail kev kho mob.

3. Tsawg kub Claus txheej txheem
Tsis tshua muaj kub Claus thev naus laus zis yog tus cwj pwm los ntawm Claus cov tshuaj tiv thaiv hauv qab cov dej lwg cov ntsiab lus, yog li nws tseem hu ua sub dew point sulfur txheej txheem rov qab. Claus cov tshuaj tiv thaiv yog cov txheej txheem exothermic muaj zog. Yog li ntawd, qhov kub tsis tshua muaj qhov tsim nyog rau kev hloov pauv ntawm qhov sib npaug mus rau cov kev taw qhia ntawm kev tsim cov sulfur, uas tuaj yeem txhim kho cov tshuaj sulfur. Raws li kev sib raug zoo ntawm Claus cov tshuaj tiv thaiv thiab chav tsev, qhov kub tsis tshua muaj Claus txheej txheem tuaj yeem muab faib ua kev ywj pheej uas tsis muaj qhov kub thiab txias Claus txheej txheem thiab ua ke nrog qhov kub thiab txias Claus txheej txheem.

4. Ua kua theem ncaj qha oxidation txheej txheem
Ua kua theem ncaj qha oxidation txheej txheem yog ib hom txheej txheem thev naus laus zis uas ncaj qha oxidizes H2S rau cov tshuaj sulfur. Lub hauv paus ntsiab lus ntawm cov txheej txheem no yog nqus cov H2S hauv cov roj av nrog cov tshuaj desulfurization, thiab tom qab ntawd oxidize nws los tsim cov tshuaj sulfur.
