Site na mmepe nke ọha mmadụ anyị, anyị na-akwado ike dị ọcha, yabụ ọchịchọ maka gas eke dị ka ike dị ọcha na-amụbakwa. Agbanyeghị, n'usoro nke iji gas eke eme ihe, ọtụtụ olulu gas na-enwekarị hydrogen sulfide, nke ga-eme ka ngwa na paịpụ ghara ịdị irè, mebie gburugburu ebe obibi ma tinye ahụike mmadụ n'ihe ize ndụ. Site na mmepe nke sayensị na teknụzụ, ojiji sara mbara nke teknụzụ desulfurization gas eke edozila nsogbu ndị a, mana n'otu oge ahụ, ọnụ ahịa nke nhicha na ọgwụgwọ gas eke amụbaala nke ọma.

Ụkpụrụ

Mkpuchi mkpụkọ molekụla (nke a na-akpọkwa desulfurization) skid, nke a na-akpọkwa molekụla sieve sweeting skid, bụ ngwaọrụ dị mkpa na nhicha gas eke ma ọ bụ ọrụ nhazi gas eke.

Mkpọchi molekul bụ kristal aluminosilicate metal alkali nke nwere nhazi ọkpụkpụ na nhazi microporous dị iche iche. Ọ bụ ihe na-amị amị nke nwere arụmọrụ dị mma, ikike nnabata dị elu na nhọrọ nnabata. Nke mbụ, enwere ọtụtụ ọwa nwere nha oghere otu na oghere edobere nke ọma na nhazi sieve molekul, nke na-enye naanị nnukwu mpaghara elu, kamakwa na-egbochi ntinye nke molekul buru ibu karịa oghere; Nke abụọ, elu sieve molekul nwere polarity dị elu n'ihi njirimara nke ionic lattice, yabụ ọ nwere ikike nnabata dị elu maka molekul ndị na-enweghị afọ ojuju, molekul polar na molekul ndị nwere ike ịgbasa. Mmiri na hydrogen sulfide bụ molekul polar, dayameta molekul dịkwa obere karịa dayameta pore nke sieve molekul. Mgbe gas raw nwere mmiri trace gafere na akwa sieve molekul na okpomọkụ ụlọ, a na-amịkọrọ mmiri trace na hydrogen sulfide, Ya mere, ọdịnaya nke mmiri na hydrogen sulfide na gas nri na-ebelata, a na-emezukwa ebumnuche nke ịkpọ nkụ na desulfurization. Usoro ntinye nke sieve molekul gụnyere njikọ capillary na ntinye anụ ahụ nke van der Waals force kpatara. Dịka usoro Kelvin si dị, njikọ capillary na-ebelata ka okpomọkụ na-abawanye, ebe njikọ anụ ahụ bụ usoro exothermic, ntinye ya na-ebelata ka okpomọkụ na-abawanye ma na-abawanye ka nrụgide na-abawanye; Ya mere, a na-emekarị usoro ntinye nke sieve molekul na obere okpomọkụ na nrụgide dị elu, ebe a na-eme mgbanwe nyocha na okpomọkụ dị elu na nrụgide dị ala. N'okpuru ọrụ nke gas regeneration dị elu, dị ọcha na obere nrụgide, ntinye sieve molekul na-ahapụ adsorbate na micropore n'ime mmiri gas regeneration ruo mgbe ọnụọgụ adsorbate dị na ntinye ahụ ruru ọkwa dị ala. O nwekwara ike itinye mmiri na hydrogen sulfide site na gas nri, na-ahụ usoro mweghachi na imegharị ihe nke sieve.

Usoro teknụzụ

E gosiri usoro usoro a na eserese ahụ. Ngalaba ahụ na-agbaso usoro ụlọ elu atọ, otu ụlọ elu maka ịmịnye ihe, otu ụlọ elu maka imeghari ihe na otu ụlọ elu maka ịjụ oyi. Mgbe gas nri batara na nkeji ahụ, a na-ebelata okpomọkụ nke gas nri site na nkeji tupu oyi, mgbe ahụ, a na-ewepụ mmiri efu site na ihe nkesa coalescence, wee banye na ụlọ elu desulfurization molecular sieve a-801, a-802 na a-803. A na-etinye mmiri na hydrogen sulfide dị na gas nri site na sieve molecular iji mezuo usoro mmịpụta mmiri na hydrogen sulfide. Gas a sachapụrụ maka mmịpụta mmiri na mwepụ hydrogen sulfide na-abanye na nzacha uzuzu gas ngwaahịa ahụ iji wepụ uzuzu sieve molecular ma na-ebupụ ya dị ka gas ngwaahịa.

Mkpọchi molekul chọrọ mmeghari ohuru mgbe ọ mịkọrọ mmiri na hydrogen sulfide ụfọdụ. A na-ebuga akụkụ nke gas ngwaahịa ahụ site na gas ngwaahịa ahụ mgbe emechara nzacha uzuzu dị ka gas mmeghari ohuru. Mgbe emechara kpoo gas ahụ ruo 270 ℃ n'ime ọkụ ọkụ, a na-ekpo ọkụ ụlọ elu ahụ nwayọ nwayọ ruo 270 ℃ site n'elu ruo ala site na ụlọ elu desulfurization sieve nke mechachara usoro adsorption, ka mmiri na hydrogen sulfide a na-etinye na molekul wee nwee ike idozi ka ha ghọọ gas mmeghari ohuru bara ụba ma mezue usoro mmeghari ohuru.

Mgbe ọ hapụsịrị ụlọ elu mmeghari ahụ, gas mmeghari ahụ na-abanye na condenser gas mmeghari ahụ ka ọ jụọ oyi ruo ihe dị ka 50 ℃, a na-ajụkwa gas ahụ ma nye ya na isi ọkụ ahụ.

A chọrọ ka ụlọ elu sieve molekul jụọ oyi mgbe emechara ya. Iji nweta ike okpomọkụ zuru oke ma jiri ya mee ihe, a na-ebu ụzọ jiri gas renovation mee ihe dị ka gas na-efe oyi, a na-ajụkwa ụlọ elu ahụ ruo ihe dị ka 50 ℃ site n'elu ruo ala site na ụlọ elu sieve desulfurization nke mechachara usoro renovation. N'otu oge ahụ, a na-ekpo ọkụ ya n'onwe ya. Mgbe gas na-efe oyi si n'ụlọ elu oyi pụta, ọ na-abanye n'ime ọkụ gas renovation maka ikpo ọkụ, wee megharịa ụlọ elu sieve desulfurization molekul dị ka gas renovation dị nro. Ngwaọrụ ahụ na-agbanwe kwa awa asatọ.
