Mmanụ na Gas

Ngwa nchọpụta gas na-arụ ọrụ dị ka ihe nchekwa dị mkpa maka nchekwa n'ụlọ ọrụ mmanụ na gas. A na-etinye ya n'ofe usoro uru niile - mmepụta, nchekwa, njem, na ojiji njedebe - iji nyochaa gas ndị na-ere ọkụ (dịka ọmụmaatụ, hydrocarbons, hydrogen), gas ndị na-egbu egbu (dịka ọmụmaatụ, hydrogen sulfide, carbon monoxide), na oke oxygen, yana ihe ndị na-agbanwe agbanwe (VOCs).

A na-etinye ihe nchọpụta gas edoziri n'ebe dị mkpa, na-enye nlekota oge ma na-akpali mkpu mgbe oke gas gafere ọkwa nchekwa. A na-eji ngwaọrụ ndị a na-ebugharị ebugharị na ndị a na-eji aka eme ihe n'oge ọrụ mmezi, nnwale olulu mmiri, na ntinye oghere dị nso, na-ahụ na nchekwa onwe onye n'ọnọdụ dị iche iche na nke a na-apụghị ịkọ amụma.

Site n'inye ịdọ aka ná ntị ozugbo maka ihe egwu dịka mmiri ozuzo, mgbawa, na nsi, ngwa nchọpụta gas na-ahụ na nchekwa nke ndị ọrụ, nkwụsi ike nke ngwa, na nrubeisi na iwu gburugburu ebe obibi.

Ụlọ Ọrụ Mmanụ

Mwepụta mmanụ:

Ngwa nchọpụta gas dị oke mkpa n'oge niile a na-ewepụta mmanụ, ebe ndị ọrụ na-eche ihe egwu na-aga n'ihu site na gas ndị na-ere ọkụ na ndị na-egbu egbu. N'oge a na-egwu olulu mmiri, na-arụ ọrụ na mmepụta, ndị na-achọpụta gas na-enyocha gas dịka methane, H2S, na hydrocarbons ndị na-agbanwe agbanwe nke nwere ike ịgbapụta site na olulu mmiri, sistemu apịtị, ma ọ bụ ngwaọrụ mmepụta.

Ngalaba Usoro Nrụpụta Ihe:

Ọrụ imezi ihe (dịka ọmụmaatụ, distillation, catalytic cracking, hydrocracking) gụnyere nkewa na mmeghachi omume okpomọkụ dị elu, nrụgide dị elu, nke nwere ike ibute ntapu nke uzuoku mmanụ ụgbọala, igwe dizel, na hydrogen sulfide (site na mmanụ dị ọcha nwere sọlfọ).

Ụlọ Ọrụ Mmepụta Kemịkalụ:

Usoro dịka mmepụta ammonia, mmepụta ethylene, na polymerization styrene gụnyere hydrogen (H₂), carbon monoxide (CO), na benzene (C₆H₆) - ihe ndị a niile dị oke ize ndụ.

Tankị Nchekwa na Ebe Ibu/Ịkwatu Ihe:

Tankị ndị na-echekwa mmanụ a gwakọtara agwakọta, ngwaahịa a nụchara anụcha (mmanụ ụgbọala, dizel), na gas mmanụ a gwakọtara agwakọta (LPG) bụ isi ihe na-akpata ihe egwu. Nwụfu nwere ike ịmepụta ngwakọta ihe mgbawa.

Sistemụ Ọgwụgwọ na Sistemụ Mkpofu Mmiri:

Ọdọ mmiri mkpofu (dịka ọmụmaatụ, ihe ndị na-ekewapụ mmanụ na mmiri, tankị mmiri na-efe efe) na-ewepụta hydrogen sulfide na methane n'ihi mmebi anaerobic nke ihe ndị dị ndụ, ebe ụlọ elu ọgwụgwọ gas nwere ike ịfụpụta sulfur dioxide (SO₂) na nitrogen oxides (NOₓ).

Ọrụ mgbasawanye nke Ụlọ Ọrụ Na-emepụta Mmanụ Ala Yan'an - Shaanxi Yanchang Petroleum (Group) Co. Ltd. Ahọpụtara sistemụ nchọpụta gas ụlọ ọrụ Xinhaosi

E tinyere akwụkwọ maka mmanụ CNPC Dagang, nke e nwetara sistemụ nchọpụta gas ụlọ ọrụ Xinhaosi maka ọrụ nchekwa.

Ụlọ Ọrụ Gas Eke

Mwepụta Gas Eke:

Olulu gas sitere n'okike nwere sọlfọ dị elu (nke nwere ọdịnaya H₂S ≥5% site na olu) na-etinye ihe egwu n'ebe olulu mmiri dị,
ikpo okwu igwu ala, na sistemụ mgbasa apịtị.

Ọrụ akụrụngwa gas nke ENN Group na China na-arụkọ ọrụ kemgbe na Xinhaosi maka ngwaahịa ụlọ ọrụ mmepụta ihe na nke ezinụlọ.

Netwọk Paịpụ Gas Eke:

Paịpụ ndị dị anya na-adịghị ike site na mmiri mmiri na ọdụ valvụ,
ngalaba osimiri/ngafe, na ebe nchekwa katodic
n'ihi mmebi ma ọ bụ mmebi nke ndị ọzọ.

Ebe Nchekwa Gas Eke:

Ebe nchekwa gas dị n'okpuru ala (ọgba nnu/ebe nchekwa mmiri ndị mebiri emebi) na ọdụ LNG (gas sitere n'okike) chọrọ nlekota maka ntapu methane na oke oxygen (iji gbochie iku ume).

Ọdụ Ọgwụgwụ:

Ọdụ CNG/LNG: Tankị nchekwa gas eke (CNG) na ihe ndị na-ekesa ihe nwere ike ịfụ methane; tankị nchekwa LNG na vaporizers chọrọ nlekota maka uzu methane na ihe egwu dị egwu.

Ọdụ Mmanụ: Tankị nchekwa n'okpuru ala (mmanụ/dizel) na ọkpọkọ ihe na-ekesa ihe na-enwekarị mmiri mmanụ ụgbọala na-agbapụta.
