Urwego rwohejuru Ubushinwa Ibicanwa bya peteroli Amazi Yinganda - Molecular sieve dehydration skid - Rongteng

Ibisobanuro

Molecular sieve dehydration skid nigikoresho cyingenzi mugusukura gaze karemano cyangwa gutunganya gaze gasanzwe. Amashanyarazi ya molekulari ni alkali icyuma cya aluminosilicate kristal ifite imiterere nuburyo bwa microporome imwe. Iyo gazi y'ibiryo irimo amazi ya trasike inyuze mu buriri bwa molekile ya sikeri ku bushyuhe bw'icyumba, amazi ya trake na mercaptan byinjira, bityo bikagabanya amazi hamwe na mercaptan biri muri gaze y'ibiryo, bikamenya intego yo kubura umwuma no gusohora. inzira ya adsorption ya sikile ya molekuline ikorwa mubushyuhe buke n'umuvuduko mwinshi, mugihe kuvugurura desorption bikorwa mubushyuhe bwinshi n'umuvuduko muke. Mugihe cyubushyuhe bwo hejuru, gazi isukuye kandi yumuvuduko muke, adsorbent ya molekile irekura adsorbate muri micropore mumyuka ya gaze ivugurura kugeza igihe ingano ya adsorbate muri adsorbent igeze kurwego rwo hasi cyane, kandi ifite ubushobozi bwo gukuramo amazi na mercaptan biva mumyuka ya federasiyo, bikamenya uburyo bushya bwo gutunganya no gutunganya ibishishwa bya molekile.
Uburyo bwa molekile ya elegitoronike ni ubwoko bwuburyo bwo kubura umwuma, bukoreshwa kenshi muburyo bwo gutandukanya ubushyuhe buke, nka gaze ya gaze ya gaze (NGL) hamwe no kubura umwuma mukubyara gaze gasanzwe (LNG). Byongeye kandi, molekile ya sivile dehidrasiyo nayo ikoreshwa mugukora gaze gasanzwe ifunitse ya lisansi yimodoka.

Molecular sie dehydrasiyo ikoreshwa mubisanzwe bikurikira:
a. Aho ikime cya gaze gasanzwe gisabwa kuba munsi ya - 40 ℃.
b. Irakwiriye kugenzura ikime cya hydrocarubone kugenzura gaze gasanzwe.
c. Gazi isanzwe idafite umwuma kandi isukurwa icyarimwe.
d. Iyo gaze karemano irimo H2S idafite umwuma kandi igashonga muri glycol, bizatera imyuka ya gaze.
e. Iyo LPG na NGL umwuma ukeneye gukuraho sulfide (H2S, CO
COS, CS2, mercaptan) icyarimwe.

Imbonerahamwe

Amatangazo yamamaza yuburiri akoreshwa mugukoresha umwuma wa molekile, bityo igice kigomba kugira byibuze ibyapa bibiri, kimwe murwego rwo kubura umwuma wa adsorption, ikindi muburyo bushya no gukonjesha. Iyo ubushobozi bwigice ari bunini cyane, inzira yiminara myinshi nayo irashobora gutegurwa.
