Chiyambi cha ndondomeko yokonza mpweya wachilengedwe ya 5MMSCMD

Cholinga chaukadaulo ichi chikuchokera ku fakitale yopangira gasi lachilengedwe ya kasitomala. Popeza mpweya wonse womwe umayenda ndi 5MMSCMD, chifukwa cha mayendedwe ndi zifukwa zina, wagawidwa m'magulu 6 a malo opangira gasi lachilengedwe 5MMSCMD, malo ogwiritsira ntchito ndi zina zothandizira, mapaipi akutali (mwiniwake amamanga mapaipi a gasi) ndipo adzatumizidwa ku Iran;

Fakitale yokonza gasi wachilengedwe iyi imaphatikizapo makamaka:

1) Seti ya makina oziziritsira mpweya: kupopa ndi kuchepetsa mpweya wachilengedwe wothamanga kwambiri womwe umatuluka m'chitsime cha mpweya, ndi kuziziritsa mpweya wachilengedwe wopopa madzi mpaka kutentha kwabwinobwino;

2) Seti ya njira yolekanitsira magawo atatu: kulekanitsa zipangizo za magawo atatu monga gasi, madzi ndi mafuta opepuka ogwirizana nawo mu mpweya wachilengedwe pambuyo popopera, kupondereza ndi kuziziritsa. Mafutawo adzatulutsidwa pambuyo pokonzedwa bwino ndi njira yoyeretsera zinyalala. Mafuta opepuka ogwirizana nawo adzakhazikika ndikulekanitsa madzi asanagulitsidwe kumsika. Mpweyawo umagawidwa m'magawo 6 motsatana kuti ulowe mu njira yochotsera sulfurization ya sitima 6 ya MDEA;

3) Dongosolo la MDEA desulfurization: kukonzekeretsa sitima 6 za zida za MMSCMD zokwana 5MMSC kuti zichotse mpweya wachilengedwe mpaka pansi pa N₂ppm ndikutumiza ku dongosolo la kuchepa kwa madzi m'thupi la molekyulu;

4) Dongosolo la kuchepa kwa madzi m'thupi pogwiritsa ntchito sieve ya molekyulu: kukonzekeretsa sitima 6 za zida za 5MMSCMD kuti zichotse chinyezi kuchokera ku mpweya wachilengedwe kuti zisaundane komanso kutsekeka kwa mapaipi panthawi yonyamula mpweya wachilengedwe mtunda wautali. Pambuyo podutsa madzi m'thupi, zidzatumizidwa ku dongosolo lokhazikika la hydrocarbon dew point;

5) Dongosolo lokhazikika la madontho a hydrocarbon dew: Kukonza magalimoto 6 a zida za sikelo ya 5MMSCMD, kugwiritsa ntchito mafiriji a propane kuti azizire, ndikuchotsa madzi m'mpweya wachilengedwe. Chotsani ma hydrocarbon olemera mumpweya wachilengedwe kuti mapaipi asazizire ndi kutsekeka panthawi yonyamula mpweya wachilengedwe kutali;

6) Dongosolo la mapaipi akutali (mapaipi a gasi amapangidwa ndi eni ake a gasi): Gasi woyenerera wokonzedwa ndi mafakitale opangira gasi wachilengedwe umatumizidwa ku Iran kudzera m'mapaipi akutali.

Malo onse opangira gasi lachilengedwe adzaphatikizapo magetsi/magetsi kuphatikizapo magetsi opangira gasi, komanso zinthu zina monga makina oyendera madzi, makina opumira mpweya a zida za nayitrogeni, makina opumira madzi opanda mchere, makina otenthetsera mafuta otentha, makina odzaza zosungunulira, makina oyeretsera ndi kutulutsa zinyalala, ndi zina zotero; nthawi yomweyo, siteshoni yonseyi ikuphatikizaponso makina otetezera monga kutulutsa mpweya.

Kufotokozera kwa dongosolo la njira

(1) Kuchepetsa mpweya wa Wellhead, kuchepetsa kuthamanga kwa magazi, kuziziritsa ndi dongosolo lolekanitsa magawo atatu

Mpweya wachilengedwe wochokera pachitsime cha mpweya umapindidwa ndi kuchepetsedwa mphamvu, ndikuziziritsidwa ndi choziziritsira mpweya musanalowe mu cholekanitsa cha magawo atatu. Pogwiritsa ntchito mphamvu yokoka, chifukwa cha kusiyana kwa kuchuluka kwa mafuta ndi madzi, madzi omasuka amamira pansi pa chidebecho, ndipo mafuta amayandama pamwamba ndikukwera pamwamba pa chotchinga cha madzi a mafuta. Mbale imalowa m'chipinda cha mafuta, ndipo chowongolera madzi choyandama chimayang'anira kutulutsa mafuta osakonzedwa pogwiritsa ntchito valavu yotulutsira mafuta kuti mafuta azikhala olimba. Madzi omasuka olekanitsidwa amatuluka kudzera mu valavu yotulutsira madzi yomwe imayendetsedwa ndi chowongolera cholumikizira madzi a mafuta kuti asunge bata la mawonekedwe a mafuta ndi madzi. Mafuta olekanitsidwa amalowa mu chokhazikika kuti apitirize kulekanitsa madzi, kenako amalowa mu thanki yosungira mafuta, komwe amasonkhana mpaka kuchuluka kwina ndipo amagulitsidwa kwa ogulitsa mafuta. Chinyezi cholekanitsidwa chimalowa m'dongosolo loyeretsera zinyalala kudzera m'dongosolo lotsekedwa lotulutsira madzi ndipo chimatulutsidwa pambuyo podutsa njira yoyeretsera.
