Usoro mgbake nke ọkụ hydrocarbons sitere na gas jikọtara ya na mpaghara mmanụ (1)

Nkemgbake nke ìhè hydrocarbons site na gas metụtara na mpaghara mmanụ bụ usoro dị oke mkpa na ụlọ ọrụ mmanụ na gas. gas Associated, nke a na-ahụkarị n'akụkụ mmanụ crude, nwere ihe ndị bara uru dị ka mmiri gas gas (NGL) na gas na mmanụ ọkụ (LPG). Ịweghachite hydrocarbons ọkụ ndị a ọ bụghị nanị na-ebuli uru nke iyi gas bawanye kamakwa ọ na-enye aka n'ibelata ikuku gas na-ekpo ọkụ. N'isiokwu a, anyị ga-enyocha mkpa NGL na LPG mgbake sitere na gas metụtara na teknụzụ ndị metụtara usoro a.

NGL mgbake site na gas metụtara na-agụnye nkewa na mmịpụta nke mmiri gas dị ka ethane, propane, na butane. Ihe ndị a nwere uru azụmaahịa dị mkpa ma na-eji ya dị ka nri nri maka osisi petrochemical, yana imepụta plastik, roba sịntetik, na ngwaahịa ụlọ ọrụ ndị ọzọ. The mgbake nkeNGL sitere na gas metụtaradị mkpa maka ịbawanye ike akụ na ụba nke iyi gas na ibelata mkpofu nke akụrụngwa bara uru.

Nkọwa nkenke nke usoro a bụ:

1) Natural gas agwakọta na boosting usoro

1) Nkọwa usoro

A na-agbanye gas na-eri nri na 0.3 MPaG wee gwakọta ya na obere nrụgide mmiri wee tinye ya na 3.9 MPaG. A na-agwakọta iyi a gwakọtara na High Pressure wee banye na ngwaọrụ ala.

2) Mepụta parameters

Ike nhazi gas:

Nrụgide dị elu: 12500 Nm³/h;

Nrụgide dị ala: 16166.7 Nm³/h;

2) Sistemụ mmiri na-ekpo ọkụ nke ikuku

1) Nkọwa usoro

Ọnụnọ nke mmiri dị na gas sitere n'okike na-ebutekarị nsonaazụ dị njọ: mmiri na gas nwere ike ịmepụta hydrates ma ọ bụ ice iji gbochie pipeline n'okpuru ọnọdụ ụfọdụ.

akpịrị ịkpọ nkụ gas na-anabata usoro mgbasa ozi sieve molekụla. Ebe ọ bụ na molecular sieve nwere ike adsorption selectivity na elu adsorption àgwà n'okpuru obere mmiri vepo akụkụ mgbali, ngwaọrụ a na-eji 4A molecular sieve dị ka akpịrị ịkpọ nkụ adsorbent.

Nkeji a na-eji usoro ụlọ elu abụọ na-amịkọrọ mmiri, na-eji usoro TSA nyochaa mmiri a na-etinye na sieve molecular, ma na-eji usoro condensation na-ekpokọta na ikewapụ mmiri na-esi na adsorbent.

2) Mepụta parameters
