Bayanin tsari na kowane naúrar don BOG reliquefying shuka

BOG na tankin ajiya na LNG yana shiga cikin akwatin sanyi na liquefaction bayan an matsa lamba da aunawa, ana sanyaya shi, an shayar da shi, kuma a sanyaya shi sosai a cikin ma'aunin zafi na farantin-fin, sannan ya dawo cikin tankin ajiya na LNG azaman samfurin LNG bayan buguwa.

Babbar hanyar fasaha ta wannan na'ura ita ce:

MRC (gauraye refrigerant) tsarin sake sake zagayowar refrigerant ana amfani dashi don shayar da duk iskar BOG mai tsabta;

Wannan tsarin tsari ya ƙunshi:

Feed gas tacewa rabuwa da matsa lamba;

LNG tsarin liquefaction;

Naúrar firiji mai gauraya;

1) Feed gas rabuwa da matsi naúrar

1) Bayanin tsari

BOG gas yana shiga cikin iskar gas mai zafi da ciyar da iskar gas mai zafi, kuma bayan matsawa, rabuwa, da ƙididdigewa, ya shiga cikin tsarin sarrafa ruwa.

Babban kayan aiki shine iskar gas mai zafi, mai ciyar da iskar gas mai zafi, mita mai gudana, naúrar kwampreso, da dai sauransu.

2)Naúrar ruwan sha

1) Bayanin tsari

BOG mai tsarki iskar gas ya fara shiga cikin na'urar musayar zafi a cikin akwatin sanyi, a hankali ana sanyaya shi ta hanyar dawo da ƙarancin zafin jiki gauraye refrigerant, sannan a sanyaya zuwa -162.°C, sannan ya shiga mai raba LNG don samun samfuran LNG.

Babban kayan aiki shine akwatin sanyi, wanda galibi ya haɗa da masu musayar zafi na faranti, masu rarraba daban-daban, da sauransu.

3) Mixed refrigerant matsawa da rabon rabo

1) Bayanin tsari

4) Naúrar dumama akwatin sanyi

1) Aikin tsarin

Kafin farawa a karon farko, wajibi ne a bushe duk BOG Hanyar kwararar iskar gas da hanyar kwararar firiji na na'urar.

Bayan aiki na dogon lokaci na akwatin sanyi na liquefaction, ragowar carbon dioxide da danshi a cikin iskar BOG mai tsabta za su taru a cikin ƙaramin zafin jiki na akwatin sanyi mai sanyi, yana haifar da haɓaka juriya da amfani da kuzari, kuma yana iya haifar da sanyi mai sanyi. akwatin don kasa yin aiki akai-akai. Sabili da haka, a cikin Bayan sake zagayowar aiki, akwatin sanyi na ruwa za a dumi kuma a narke tare da dumama nitrogen ko BOG gas.

2) Bayanin tsari

BOG iskar gas daga hanyar sadarwa ta bututun nitrogen yana mai zafi da lantarki zuwa 60 ~ 70℃ , sa'an nan kuma ya shiga tashoshi na gaba da baya na iskar gas da kuma tashoshi na gaba da baya na refrigerant a cikin akwati mai sanyi don dumama, sa'an nan kuma yana mai tsanani daga zubar da akwatin sanyi.
