100MMSCFD na cire sulfur na iskar gas ta halitta tare da tsarin maganin MDEA

An haifi Sichuan Hengzhong Clean Energy Equipment Co., Ltd., a shekarar 2012 kuma za mu iya samar da mafita da kayan aiki don kayan aikin maganin wellhead, kayan aikin sanyaya iskar gas na halitta, kunshin dawo da sulfur, Na'urar cire LPG da kuma dawo da NGL, Kamfanin samar da ruwa na LNG, sashin samar da hydrogen, kunshin cire helium, saitin janareta na iskar gas.

Cikakken tsarin cire sulfur ya haɗa da tsarin guda uku: tsarin aiki, tsarin sarrafa kayan aiki da tsarin amfani. Dangane da hanyoyin iska daban-daban, ana iya canza shi.

Dangane da ainihin yanayin tushen iskar gas, muna ɗaukar mafi kyawun tsari da tsarin da ya fi araha don biyan buƙatun abokan ciniki daban-daban. Kayan aikin da aka ɗora a kan skid suna sa sufuri da shigarwa su fi dacewa.

1. Babban hanyar amfani da maganin MDEA cire CO2 da H2S:

Na halitta daga sama yana shiga sashin cire acid, wanda ke amfani da maganin MDEA don cire iskar gas kamar CO2\H2S daga iskar gas ɗin da ba ta da amfani.

Iskar gas ta halitta tana shiga mai shanyewar daga ƙasa kuma tana kwarara sama. Maganin MDEA mai cikakken sake farfaɗowa (maganin lean) yana shiga mai shanyewar daga sama kuma yana kwarara ƙasa. Ruwan da ke gaba da maganin MDEA da iskar gas ta halitta suna haɗuwa da mai shanyewar gaba ɗaya, suna shanye CO2 da H2S a cikin iskar gas sannan su mayar da su zuwa matakin ruwa. Ana zana abubuwan da ba a sha ba daga saman mai shanyewar kuma suna shiga mai sanyaya da mai raba gas ta deacidification. Iskar gas da ke fita daga mai raba gas ta deacidification tana shiga sashin sanyaya iskar gas, kuma ana aika da condensate zuwa tankin walƙiya.

TYawan CO2 a cikin iskar gas da aka yi wa magani bai wuce 50 PPM ba, kuma yawan H2S bai wuce 4 PPM ba.

Maganin MDEA wanda ya sha CO2 da H2S, wanda ake kira ruwa mai arziki, ana aika shi zuwa hasumiyar walƙiya, inda ake rage matsin lamba kuma ana aika iskar gas mai walƙiya da ta fito zuwa tsarin iskar iska. Sai ruwan mai cike da walƙiya ya canza zafi da ruwan (ruwa mai laushi) wanda ke fitowa daga ƙasan hasumiyar sabuntawa. Daga nan sai a ɗaga zafin zuwa ~203°F sannan a aika shi zuwa ɓangaren sama na hasumiyar sabuntawa, inda za a cire shi da sake farfaɗowa har sai ruwan mai cike da iskar ya kai ga yawan da ake buƙata.

Ruwan da ke fitowa daga hasumiyar sake farfaɗowa yana ratsawa ta cikin na'urar musayar zafi mai laushi da kuma na'urar sanyaya ruwa mai laushi, ana sanyaya ta zuwa 113°F, kuma famfon ruwa mai laushi yana matsa shi kafin ya shiga saman hasumiyar sha.

Iskar gas da ke fitowa daga saman hasumiyar sake farfaɗowa ta ratsa ta cikin na'urar sanyaya iskar acid kuma ta shiga na'urar raba iskar acid. Ana aika iskar gas da ke fitowa daga na'urar raba iskar acid zuwa tsarin fitar da iskar acid, kuma na'urar ta koma cikin tankin ajiyar iskar MDEA.

Ana dumama tushen zafi na tukunyar dumama hasumiyar mai da mai mai zafi.

Babban kayan aikin wannan na'urar shine hasumiyar sha da hasumiyar farfadowa.

2. Tsarin sarrafa kayan aiki

Domin a sa ido sosai kan yadda ake samar da cikakken kayan aiki, da kuma tabbatar da ingantaccen aiki da kuma sauƙin aiki da kulawa, tsarin kula da kayan aiki ya haɗa da:

Tsarin sarrafawa mai rarrabawa (DCS)

Tsarin Kayan Aiki na Tsaro (SIS)

Tsarin Gargaɗin Gobara da Gas (FGS)

Talabijin mai rufewa (CCTV)

Tsarin nazari

3. Tsarin amfani

Wannan tsarin ya ƙunshi galibi: na'urar iska ta kayan aiki, na'urar nitrogen, na'urar mai ta hanyar zafi, na'urar ruwa mai narkewa da kuma na'urar sanyaya ruwa mai zagayawa.
