Mea kūʻai aku ʻo China MDEA Decarburization Skid kiʻekiʻe - Molecular sieve dehydration skid - Rongteng

wehewehe

ʻO ka molecular sieve dehydration skid he mea nui i ka hoʻomaʻemaʻe kinoea maoli a i ʻole ka hoʻomaʻemaʻe kinoea maoli. ʻO ka sieve molecular kahi aniani metala aluminosilicate alkali me ka hoʻolālā hana a me ke ʻano microporous like ʻole. Ke hele nei ke kinoea hānai e loaʻa ana ka wai trace i loko o ka molecular sieve moena i ka lumi wela, e hoʻopili ʻia ka wai trace a me ka mercaptan, pēlā e hōʻemi ai i ka wai a me ka mercaptan ma loko o ke kinoea hānai, e ʻike ana i ke kumu o ka dehydration a me ka desulfurization. ke kaʻina hana adsorption o ka molecular sieve e hana maʻamau i ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe kiʻekiʻe, aʻo ka desorption regeneration e hana ʻia ma ke kiʻekiʻe wela a me ke kaomi haʻahaʻa. Ma lalo o ka hana o kiʻekiʻe wela, maʻemaʻe a me ka haʻahaʻa puʻe regeneration kinoea, ka molecular sieve adsorbent hoʻokuʻu i ka adsorbate i ka micropore i loko o ka regeneration kinoea kahe a hiki i ka nui o ka adsorbate i loko o ka adsorbent hiki i kahi haʻahaʻa haʻahaʻa, a loaʻa iā ia ka hiki ke komo i ka wai a me ka mercaptan mai ke kinoea hānai, ʻike i ka hana hou a me ka recycling sieve kaʻina o ka mole.
ʻO ke ʻano kānana molecular kahi ʻano o ka dehydration hohonu, i hoʻohana pinepine ʻia i ke kaʻina hoʻokaʻawale condensation haʻahaʻa, e like me ka hoʻihoʻi ʻana o ke kinoea condensate (NGL) a me ke kaʻina dehydration i ka hana ʻana i ke kinoea maoli liquefied (LNG). Eia kekahi, hoʻohana ʻia ka molecular sieve dehydration i ka hana ʻana i ke kinoea kūlohelohe i hoʻopili ʻia no ka wahie kaʻa.

Hoʻohana maʻamau ka molecular sieve dehydration i nā manawa aʻe:
a. Kahi e pono ai ka hau o ke kinoea maoli ma lalo o – 40 ℃.
b. He kūpono ia no ka hoʻomalu ʻana i ka wahi hau hydrocarbon o ke kinoea kūlohelohe kiʻekiʻe.
c. Hoʻomaʻemaʻe ʻia ke kinoea kūlohelohe i ka manawa like.
d. Ke hoʻoheheʻe ʻia ke kinoea maoli i loko o ka H2S a hoʻoheheʻe ʻia i ka glycol, e hoʻokuʻu ʻia ke kinoea hoʻōla hou.
e. I ka wā e pono ai ka LPG a me NGL dehydration e wehe i ka trace sulfide (H2S, CO
COS, CS2, mercaptan) i ka manawa like.

Kiʻi kahe

Hoʻohana ʻia nā adsorbers moe paʻa no ka molecular sieve dehydration, no laila e loaʻa i ka ʻāpana ʻelua mau adsorbers, hoʻokahi i ka adsorption dehydration stage, ʻo kekahi i ka hana hou a me ka hoʻoilo. Ke nui loa ka mana o ka ʻāpana, hiki ke hoʻonohonoho ʻia ke kaʻina hana hale kiaʻi lehulehu.
