Nkọwa

Igwe mmiri na-ekpo ọkụ molecular sieve bụ isi ngwaọrụ na-asachapụ gas sitere n'okike 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. 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 siri ike nke molecular bụ ụdị usoro mmiri mmiri miri emi, nke a na-ejikarị eme ihe na usoro nkewa nke ikuku dị ala, dịka mgbake gas condensate (NGL) na usoro mmiri mmiri na mmepụta nke gas gas (LNG). Tụkwasị na nke a, a na-ejikwa mmiri mmiri na-ekpo ọkụ molecular sieve na-emepụta gas sitere n'okike maka mmanụ ụgbọala.

akpịrị ịkpọ nkụ molecular sieve na-emetụtakarị oge ndị a:
a. Ebe a chọrọ ka igirigi nke ikuku gas dị ala karịa - 40 ℃.
b. Ọ dị mma maka njikwa igirigi hydrocarbon nke ikuku ikuku dị elu.
c. A na-ekpochapụ gas na-emepụta mmiri ma na-asachapụ n'otu oge ahụ.
d. Mgbe ikuku sitere n'okike nwere H2S akpọnwụwo wee gbazee na glycol, ọ ga-eme ka ikuku nke mmeghari ohuru pụta.
e. Mgbe akpịrị ịkpọ nkụ LPG na NGL kwesịrị iwepu trace sulfide (H2S, CO
COS, CS2, mercaptan) n'otu oge.

A na-eji adsorbers ihe ndina eme ihe maka akpịrị ịkpọ nkụ molecular sieve, yabụ otu ahụ kwesịrị ịnwe opekata mpe abụọ adsorbers, otu na ọkwa nkụda mmụọ adsorption, nke ọzọ na nrụgharị na ọkwa jụrụ oyi. Mgbe ikike nke unit ahụ buru ibu, a pụkwara ịhazi usoro ụlọ elu ọtụtụ.
