Ndị na-ebubata ngwaahịa LNG dị elu nke China - 10 ~ 20 × 104m3 / D omenala LNG Liquefaction Plant - Rongteng

Ọdịdị nke LNG

a) Ihe mejupụtara

LNG / LCBM bụ ngwakọta hydrocarbon na methane dị ka ihe bụ isi, nke nwere obere ethane, propane, nitrogen na ihe ndị ọzọ na-adịkarị na gas.

N'ikwu okwu n'ozuzu, ọdịnaya methane nke LNG/LCBM dị elu karịa 80% na ọdịnaya nitrogen dị ala karịa 3%.

Ọ bụ ezie na akụkụ bụ isi nke LNG bụ methane, a pụghị ịchọta ihe anụ ahụ na kemịkal nke LNG site na methane dị ọcha.

Enwere ike ịhụ njirimara anụ ahụ na temomenaịka nke methane na ihe ndị ọzọ sitere na gas n'ime akwụkwọ ntụaka dị mkpa na akwụkwọ ntuziaka thermodynamic.

b) Njupụta

Njupụta nke LNG / LCBM dabere na ihe mejupụtara ya, na-adịkarị n'etiti 430kg / m3 na 470kg / m3, mana n'ọnọdụ ụfọdụ ọ nwere ike ịdị elu dị ka 520kg / m3. Njupụta bụkwa ọrụ nke okpomọkụ mmiri mmiri, na gradient mgbanwe ya dị ihe dịka 1.35kg/m3. ℃

Akụrụngwa nke osisi LNG

1) Isi usoro usoro isi ihe mejupụtara nke osisi LNG / LCBM:

Nri gas filtration na mkpakọ usoro

Sistemụ deacidification nri gas

Nri gas ihicha usoro

Na-enye nri gas arọ hydrocarbon mwepụ usoro

Mwepụ Mercury na usoro nzacha nke nri gas

Ọcha gas dị ala okpomọkụ usoro liquefaction

LNG nchekwa na njem na usoro mkpakọ bog

Sistemụ refrigeration isi yana / ma ọ bụ sistem nju oyi inyeaka

Usoro enyemaka nchekwa

Ngwá ọrụ na usoro nchịkwa eletrik
