Zinthu zaukadaulo za dongosolo lokonzekera mpweya wa chakudya ndi makina oziziritsira madzi ndi firiji mu ntchito ya fakitale ya LNG

Dongosolo lokonzekera mpweya wodyetsa chakudya
Njira yogwiritsira ntchito njira yosankhidwa kuti igwiritsidwe ntchito Dongosolo lokonzekera mpweya wothira chakudya lili ndi makhalidwe awa:
(1) Poyerekeza ndi njira ya MEA, njira ya MDEA ili ndi makhalidwe a thovu lochepa, dzimbiri lochepa komanso kutaya kwa amine kochepa.
(2) Chipangizochi chimagwiritsa ntchito MDEA wet decarburization, ndipo palibe kugwiritsa ntchito mpweya wokonzanso.
(3) Pampu yozungulira ya MDEA imagwiritsa ntchito pampu ya centrifugal yothamanga kwambiri, yomwe ili ndi kudalirika kwakukulu, kugwiritsa ntchito mphamvu zochepa komanso kukonza kochepa.
(4) Kulowetsedwa kwa sefa ya mamolekyulu kungagwiritsidwe ntchito pochotsa madzi m'thupi, ndipo kumakhalabe ndi makhalidwe ambiri olowetsedwa ngakhale pamene nthunzi ya madzi ili yochepa.
(5) Kugwiritsa ntchito mpweya wopangidwa kuti muchotse ma hydrocarbon olemera kungachotse ma hydrocarbon onunkhira ndi ma hydrocarbon olemera a C6 +, kuthetsa vuto la kuzizira ndi kutsekeka kwa kutentha kochepa, ndikuwonetsetsa kuti ntchito ikugwira ntchito kwa nthawi yayitali.
(6) Mercury imakumana ndi sulfure pa sulfure yomwe yalowetsedwa mu activated carbon kuti ipange mercury sulfide, yomwe imayamwa pa activated carbon kuti ikwaniritse cholinga chochotsa mercury. Kugwiritsa ntchito sulfure yomwe yalowetsedwa mu activated carbon kuti ichotse mercury kuli ndi mtengo wotsika.
(7) Chosefera cholondola chimatha kusefa sieve ya molekyulu ndi fumbi la kaboni lomwe layambitsidwa kufika pa 5 μm pansi pake.

Makina oyeretsera madzi ndi firiji
Njira yosankhidwa yochitira makina oziziritsira madzi ndi ozizira ndi MRC (mixed refrigerant) cycle refrigerant, yomwe imadziwika ndi:
(1) Kugwiritsa ntchito mphamvu zochepa. Njira iyi imagwiritsa ntchito mphamvu zochepa kwambiri pakati pa njira zoziziritsira zomwe zimagwiritsidwa ntchito kwambiri, zomwe zimapangitsa kuti mtengo wa zinthuzo ukhale wopikisana pamsika.
(2) Dongosolo logawanitsa zinthu mufiriji silidalira dongosolo logawanitsa zinthu. Pa nthawi yogwira ntchito, dongosolo logawanitsa zinthu limadzazanso firiji ku dongosolo logawanitsa zinthu kuti lizigwira ntchito bwino; Pambuyo poti chipangizocho chatsekedwa, dongosolo logawanitsa zinthu limatha kusunga firiji kuchokera ku gawo lamphamvu la dongosolo logawanitsa zinthu popanda kutulutsa firiji. Cholinga chochita izi: choyamba, kusunga firiji, ndipo chachiwiri, kufupikitsa nthawi yoyambira ina. Nthawi yoyambira chipangizo chogawanitsa zinthu ndi yochepera maola 5.
(3) Kuchuluka ndi kuthamanga kwa makina oziziritsira ziyenera kupangidwa moyenera. Pambuyo poti chipangizocho chatsekedwa, poganizira kuti mafiriji onse atenthedwa kutentha kwabwinobwino ndipo kuthamanga kuli koyenera, makinawo akhoza kukhalabe ndi mafiriji onse, kuonetsetsa kuti ziwalo zonse za makinawo sizikupanikizika kwambiri komanso kutulutsa mpweya woipa, ndikulola kuti firijiyo ikhalebe mu makinawo kwa nthawi yayitali.
(4) Ma valve onse a chipangizo choyeretsera madzi chotentha kwambiri amaikidwa kunja kwa bokosi lozizira ndipo amawotcherera kuti achepetse malo otayikira madzi ndikuthandizira kukonza ma valve. Palibe kulumikizana kwa flange mu bokosi lozizira kuti achepetse malo otayikira madzi mu bokosi lozizira. Thermometer ya ma point ambiri ndi probe ya gasi zimakonzedwa kuti ziwunikire kutuluka kwa madzi mu bokosi lozizira nthawi yeniyeni.
(5) Ukadaulo wapamwamba umagwiritsidwa ntchito kwambiri popanga bokosi lozizira. Kusanthula kwathunthu kwa chimango, mapaipi ndi kupsinjika kwapafupi kudzachitika kuti zitsimikizire kudalirika kwa bokosi lozizira kuchokera ku mtundu wa kapangidwe. Choyamba, Mapulogalamu Opanga 3D aukadaulo a Solidworks amagwiritsidwa ntchito kukhazikitsa chitsanzo cha 3D cha chimango cha bokosi lozizira ndi zida zapaipi; Kenako, cosmos imagwiritsidwa ntchito kusanthula kupsinjika kwa chimango; Kuti akwaniritse kapangidwe kosinthasintha ka mapaipi otsika kutentha, pulogalamu yaukadaulo yowunikira kupsinjika kwa mapaipi ya CAESAR II imagwiritsidwa ntchito kusanthula kupsinjika kwa mapaipi; Mukakumana ndi vuto la kutseguka papaipi kapena ngakhale kutsegula kwakukulu, kuti zitsimikizire kuti kupsinjika komwe kuli potseguka kuli mkati mwa mulingo wololedwa womwe watchulidwa mu muyezo wadziko lonse, pulogalamu ya ANSYS idzagwiritsidwa ntchito kusanthula kupsinjika kwapafupi. Onani Mutu 14 kuti mudziwe zambiri.
