Ụlọ ọrụ skid na-atọ ụtọ nke ọma nke China Natural Gas - Molecular sieve desulphurization skid - Rongteng

Ụkpụrụ

Molecular sieve desulphurization (desulfurization) skid, nke a na-akpọkwa molecular sieve sweeting skid, bụ ihe dị mkpa na-eme ka ikuku dị ọcha ma ọ bụ ntụ oyi ikuku. Molecular sieve bụ alkali metal aluminosilicate crystal na kpuchie Ọdịdị na edo microporous Ọdịdị. Mgbe nri gas nke nwere trace mmiri na-agafe na akwa akwa molecular na okpomọkụ, a na-etinye ya na mmiri mmiri na mercaptan, si otú a na-ebelata mmiri na mercaptan n'ime nri gas, na-aghọta nzube nke akpịrị ịkpọ nkụ na desulfurization. Usoro mgbasa ozi nke sieve molecular na-agụnye condensation capillary na mgbasa ozi anụ ahụ nke van der Waals na-akpata. Site na nhazi nke Kelvin, a na-ahụta na nkwụsị nke capillary na-ebelata na mmụba nke okpomọkụ, ebe mgbasa ozi anụ ahụ bụ usoro exothermic, na mgbasa ozi ya na-ebelata na mmụba nke okpomọkụ ma na-abawanye na mmụba nke nrụgide; ya mere, a na-emekarị usoro mgbasa ozi nke sieve molecular na obere okpomọkụ na nrụgide dị elu, ebe a na-emeghachi nrụpụta nke desorption na okpomọkụ dị elu na obere nrụgide. N'okpuru omume nke elu okpomọkụ, dị ọcha na ala mgbali regeneration gas, molekụla sieve adsorbent tọhapụrụ adsorbate na micropore n'ime regeneration gas eruba ruo mgbe ego nke adsorbate na adsorbent ruru a nnọọ ala larịị, na nwere ike na-amịkọrọ mmiri na mercaptan si nri gas, na-aghọta na regeneration na recycling usoro nke molekul.

Usoro teknụzụ

Usoro eruba nke eke gas molecular sieve desulphurization (desulfurization) skid ka egosiri na eserese. Ngalaba ahụ na-anabata usoro ụlọ elu atọ, otu mgbasa ozi ụlọ elu, otu nrụpụta ụlọ elu na otu ụlọ elu jụrụ oyi. Mgbe ewepụsịrị mmiri mmiri hydrocarbon agbakwunyere site na nkesa gas nzacha nri, gas nri na-abanye n'ụlọ elu sieve desulfurization molekụla. Mmiri na mercaptan dị n'ime gas nri na-esi na sieve molekụla na-eme ka ọ ghọta na akpịrị ịkpọ nkụ na usoro mgbasa ozi mercaptan. Gas dị ọcha site na akpịrị ịkpọ nkụ na mwepụ mercaptan na-abanye n'ime ngwaahịa gas uzuzu uzuzu iji wepu uzuzu siri ike nke molikula, wee bupu ya dị ka gas ngwaahịa.

Ọ dị mkpa imegharị sieves molekụla mgbe ha gbasasịrị ụfọdụ mmiri na mercaptan. Mgbe nzacha ngwaahịa gas uzuzu, a na-amịpụta akụkụ nke ngwaahịa gas dị ka ume ọhụrụ gas. Mgbe gas na-ewe iwe ruo 300 ℃ site na ikpo ọkụ ọkụ, ụlọ elu na-nwayọọ nwayọọ kpụ ọkụ n'ọnụ ruo 272 ℃ site molekụla sieve desulfurization tower nke dechara adsorption usoro si ala ruo n'elu, nke mere na mmiri na mercaptan adsorbed na molekul sieve nwere ike kewapụrụ wee ghọọ ọgaranya regenerative gas usoro mezue.
