Akpaghị aka gas nkesa ojii

GRS - nkesa ebe nyere na akụrụngwa na-enye ohere iji belata nrụgide nke gas ọnọ si idé netwọk ahụ chọrọ larịị. Ke adianade do, ọrụ ojii na-agụnye nzacha na odorization, nkesa na idebe iwesa gas.

Gas nkesa ebe a bụ nke ikpeazụ ihe na yinye nke gas nnyefe usoro na n'otu oge isi Ọdịdị maka mepere emepe gas ọkọnọ na usoro. Ebe ọ bụ na ndị nchupu nke gas tụkwasị obodo na nnukwu ulo oru na ụlọ ọrụ ndị na-adịghị anakwere GDS na-nyere nchedo. Ọzọkwa, na-echebe ngwá e mere na ụkpụrụ nke redundancy. The ndabere akara na-arụ ọrụ mgbe n'usoro isi akara Mbelata.

GDS e mere na-:

• anata gas site na isi gas pipelines;
• ọcha ya si dị iche iche n'ibu adịghị;
• Decompression nye ụkpụrụ omume chọrọ n'obodo ukwu na usoro;
• ịnọgide na-enwe nsogbu na a mgbe nile na-larịị;
• odorizing gas na kpo oku;
• mkpebi siri ike nke ya efu.

ụdị ụgbọ

GDS na akpaghị aka gas nkesa ebe na-ekewa site na nzube ha:

• Automatic na alaka nke isi gas pipelines - iji hụ na gas nke obere niile. Ọzọkwa kewara gas akara ihe (1000-30000 nm ³ / h) na a gas akara unit (1500 m ³ / h).
• Control na nkesa emmepe - oriri ụlọ ọrụ na ime obodo akụrụngwa, pipelines mgbanaka gburugburu nnukwu ógbè na obodo nta 2000-12000 m ³ / h).
• Egbute GRS - arụnyere na gas ubi, site ọcha nke amịpụtara akụrụngwa si mmiri ma adịghị.
• End ụgbọ - na-wuru kpọmkwem site na-eji ọkụ (ụlọ ọrụ, obodo).

akpaaka

Na-adịbeghị anya, ọtụtụ-eji akpaghị aka gas nkesa ojii. AGDS ike 200,000 m ³ / h mee unattended. Na nke a, na ebe a nwere ọtụtụ ihe na ngwá na instrumentation, ikwe na-ebu ya ime ihe na akpaka mode.

Mmezi nke GDS rụrụ remotely. The ọrụ nke gas nkesa ụgbọ, na-emekarị odude ke ogige nke ọrụ nzukọ, nlekota oru nwere ike mere ọbụna n'ụlọ. Ọ bụrụ na ihe mberede ụda na ìhè n'ókè na-ebute site ná ogige na n'ebe obibi rụọ, nke na-emi odude nsannsan karịa 0,5 km si achịkwa ojii. GDS ọrụ arụmọrụ n'elu 200,000 m ³ / h bụ na e mere ụgbọ ọrụ.

akụrụngwa

Gas nkesa ebe na-agụnye a coherent set nke nkà na ụzụ akụrụngwa:

• disconnecting ngwaọrụ uzo mmiri;
• nzacha;
• okpomọkụ;
• a akara ibelata na inye iwu gas mgbali;
• Metering ngwaọrụ abata gas eruba;
• disconnecting ngwaọrụ na mmepụta.

Ọ na-enweta na-abata gas nkesa ojii. Scheme ya ije tinyere nhazi yinye dị ka ndị a:

1. Site gas isi pipeline na-akpa iche ngwaọrụ na-ewe ebe na mmalite na-abatakwa iyo.
2. Mgbe nke ahụ gasịrị ọ na-agbara ndi mmadu n'ime akpa ogbo Mbelata, na-enwe abụọ ma ọ bụ atọ e, otu onye nke bụ a ndabere. Mgbe e nwere ihe abụọ ịkpụ-edoghi, nọrọ na njikere eri na gbakọọ na otu narị percent ikike, mgbe na ihe banyere atọ edoghi - 50%. Njikere akara mgbe kwuru circuit nwere ike ji mee ka uzo akpa ogbo.
3. Ọ bụrụ na uzo mmiri nrụgide bụ 4 MPa GDS, akpa ogbo gas mgbali mbelata na 1-1.2 MPa, na nke abụọ ogbo ka 0.2-0.3 MPa. Mgbe nke abụọ ogbo gas mgbali ga nwere a uru nke 0.6-0.7 MPa.

Echichi nke nzacha na mgbali akara

Nhọrọ echichi ohere nyo na-adabere na input mgbali na gas mejupụtara. Ọ bụrụ na nkesa ebe na-enweta mmiri gas, na nzacha ga-arụnyere tupu 1st ogbo Mbelata. The nzacha na nke a ga-adị ka a ghọọ mmanụ ọnyà, na n'ibu adịghị. Mgbe nke ahụ gasịrị, na ngwakọta nke ájá na ghọọ mmanụ abatakwa sedimentation tankị.

Ọ bụrụ na ndenye GDS arụ ọrụ mgbali erughị 2 MPa, na nzacha na-setịpụrụ mgbe 1st ogbo Mbelata. N'ọnọdụ dị otú a atụmatụ ọnọdụ nzacha na-emepụta gafere (gbakọta uzo akara) nke mbụ ogbo. The nzacha na nke a na-atọrọ ka a mgbali nke 2.5 MPa. Site na-amụba gas uzo mmiri mgbali nke n'elu 2.5 MPa, na disconnecting ngwaọrụ na uzo akara a na-emechi na gas nri n'ime akara nke 1st ogbo Mbelata. Mgbe ya Itie gas nri nke abụọ ogbo, na mgbe 2 nkeji - a-agbapụta n'ahụ pipeline.

Ọ bụrụ na nkesa ebe na-achọ nnọchi ngwá maka mbenata isi akara, nakwa dị ka na-eke mberede mepụtara apụ a akara na-emeghe uzo akara nyere na a adaghị na ngwaọrụ na a mbenata valvụ. Ukpụhọde gas eruba ọnụego na nsogbu a rụrụ na nke a aka.

The ngwaọrụ nke akpaghị aka gas nkesa ojii

Akpaghị aka gas nkesa ụgbọ nwere ọtụtụ nhọrọ maka akụrụngwa layout. Otú ọ dị, ha ga-niile a ga-sonye na akaụntụ dị ka a ize ndụ nke hydrate guzobere na oyi n'èzí mpụga ụsụụ ndị agha Mbelata.
