1  Nchịkọta Sistemụ

Gas nri na-abanye na sistemụ tupu a gwọọ gas eke mgbe a sachara ya, kewapụ ya, chịkwaa nrụgide ma tụọ ya. Mgbe ewepụchara CO2, gas a na-enye nri na-abanye na sistemụ tupu a gwọọ gas eke mgbe a sachara ya, kewapụ ya, ma chịkwaa nrụgide ya.₂, H₂O, nnukwu hydrocarbons na Hg, ọ na-abanye n'ime igbe oyi nke liquefaction, a na-ajụkwa ya oyi, na-agbaze ya mmiri ...

Ụzọ teknụzụ kachasị mkpa nke ngwaọrụ a bụ:

• Jiri MDEA wepụ carbon dioxide;

• A na-eji ihe mkpuchi molekụla ewepụ mmirir
• Jiri carbon eme ihe iji wepụ nnukwu hydrocarbons;

• Jiri carbon e tinyere n'ime sọlfọ iji wepụ mercury;

• Jiri ihe nzacha ziri ezi mee nzacha sieve molekul na uzuzu carbon arụ ọrụ;

• A na-eji usoro MRC (mgwakọta refrigerant) na-eme ka gas eke niile dị ọcha dị mmiri mmiri;

  Usoro usoro a gụnyere:

• Nzacha na nkewa nke gas na-eri nri, usoro nhazi nrụgide na usoro nha;

• Usoro ọgwụgwọ tupu oge eruo (gụnyere decarbonization, ịkpọ nkụ, iwepụ nnukwu hydrocarbon, iwepụ mercury, na iwepụ uzuzu);

• Sistemụ nhazi MR na sistemụ okirikiri mkpakọ MR;

• sistemụ mmiri mmiri LNG;

• Sistemụ imegharị ihe BOG

2   Nkọwa nke sistemụ ọ bụla

2.1      Nkewa nzacha gas na nhazi nrụgide na-enye nri

1) Nkọwa usoro

A na-achịkwa gas nri sitere na elu mmiri site na nrụgide wee banye na ihe nkesa nzacha gas nri, wee banye na sistemụ ala mgbe emechara ya, kewapụ ya ma tụọ ya.

Ngwa ọrụ ya bụ isi bụ ihe nkesa ihe nzacha gas, mita mmiri, compressor na ihe ndị ọzọ.

2) Paramita nhazi

Ike njikwa: 10 × 10 ⁴ Nm ³ /ụbọchị

Oke nhazi: 50%~110%

Nrụgide mpụta nke kompresọọ: 5. 2Mpa.g

2.2      Ngalaba deacidification nke gas na-eri nri

1) Nkọwa usoro

Mmanụ nri sitere na mmiri dị n'elu na-abanye na ngalaba deacidification, otu a na-ejikwa usoro nke ngwọta MDEA iji wepụ gas acid dị ka CO₂ na H₂S na gas nri.

Gas sitere n'okike na-esi n'akụkụ ala nke ụlọ elu nnabata abanye ma gafere site n'ala ruo n'elu; mmiri MDEA emegharịrị nke ọma (mmiri dị nro) na-esi n'akụkụ elu nke ụlọ elu nnabata abanye, na-agafe site n'elu ruo na ala, mmiri MDEA na gas sitere n'okike na-asọ n'akụkụ nke ọzọ na-adị n'ụlọ elu nnabata. Mgbe emetụrụ ya aka nke ọma, CO₂ na gas _bụ A na-etinye ihe ndị a na-amịkọrọ n'ime mmiri mmiri, a na-ewepụtakwa ihe ndị a na-amịkọrọghị site n'elu ụlọ elu nnabata ahụ wee banye na ihe na-ekpo ọkụ na ihe nkewa gas nke a na-amịkọrọghị. Gas nke na-esi na ihe nkewa gas nke a na-amịkọrọghị emepụta abanye na ngalaba mwepụ mercury gas nke a na-ewepụta, ihe nkewa ahụ na-agakwa na tankị ọkụ.

Kọlọ₂ ọdịnaya nke ihe ndị e ji mee ihe n'ime ihe ndị e ji mee ihe erughị 50ppmv.

MEDA weghaara CO₂ a na-akpọ ya mmiri mmiri bara ụba, ma ziga ya na ụlọ elu ọkụ, a na-ezigakwa gas sitere n'okike nke a na-agbapụta n'okpuru mbelata nrụgide na sistemụ mmanụ ọkụ. Mgbe ọ gbasasịrị, mmiri mmiri bara ụba na-agbanwe okpomọkụ na mmiri mmiri (mmiri dị nro) nke na-esi n'ala ụlọ elu mmeghari ahụ apụta, wee bulie okpomọkụ ahụ ruo ~98 °C iji gaa n'elu ụlọ elu mmeghari ahụ.

Mmiri mmiri dị nro nke si n'ụlọ elu mmeghari ahụ na-agafe n'ime ihe na-agbanwe okpomọkụ mmiri dị nro na ihe na-ajụ oyi mmiri dị nro, mmiri mmiri dị nro ahụ na-ajụ oyi ruo ~40 ℃, mgbe mgbapụta mmiri dị nro ahụ rụsịrị ya, ọ na-esi n'akụkụ elu nke ụlọ elu nnabata abanye.

Gas dị n'elu ebe a na-esi enweta ihe na-ekpo ọkụ gas acid wee banye na ihe na-ekewa gas acid gas. A na-eziga gas sitere na ihe na-ekewa gas acid na sistemụ mwepụ gas acid, a na-etinyekwa condensate site na mgbapụta mgbake wee ziga ya na ihe na-ekewa flash.

A na-eji mmanụ nnyefe okpomọkụ ekpo ọkụ isi iyi okpomọkụ nke reboiler ụlọ elu mmeghari.

Isi ihe eji arụ ọrụ nke ngalaba a bụ ụlọ elu nnabata na ụlọ elu mmeghari ohuru.

2) Paramita nhazi

Ike njikwa: 10 × 10 ⁴ Nm ³ /ụbọchị

Mmanụ gas CO₂ isi ihe nhazi: 3%

Nrụgide ọrụ nke ụlọ elu nnabata: 5Mpa.G

Okpomọkụ ọrụ nke ụlọ elu nnabata: 40 ℃ ~ 60 ℃

Ụlọ elu mmeghari ohuru: 0.03 Mpa.G~0.05 Mpa.G

Okpomọkụ ọrụ ụlọ elu mmeghari ohuru: 95 ℃ ~ 120 ℃

Isi iyi okpomọkụ na-agbanwe agbanwe: mmanụ nnyefe okpomọkụ
