Mea kūʻai kiʻekiʻe kiʻekiʻe ʻo China Natural Gas Dehydration Unit - Molecular sieve desulphurization skid - Rongteng

Kumukānāwai

ʻO ka molecular sieve desulphurization (desulfurization) skid, i kapa ʻia hoʻi ka molecular sieve sweeting 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. ʻO ke kaʻina hana adsorption o ka sieve molecular e pili ana i ka condensation capillary a me ka adsorption kino i hoʻokumu ʻia e ka ikaika van der Waals. Mai ka hoʻohālikelike Kelvin, hiki ke ʻike i ka nāwaliwali o ka condensation capillary me ka piʻi ʻana o ka mahana, ʻoiai ʻo ka adsorption kino he hana exothermic, a nāwaliwali kona adsorption me ka piʻi ʻana o ka mahana a piʻi me ka piʻi ʻana o ke kaomi; No laila, ke kaʻina hana adsorption o ka molecular sieve e hana maʻamau i ka haʻahaʻa haʻahaʻa a me ke kiʻekiʻe kiʻekiʻe, ʻoiai ka desorption regeneration i lawe 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.

Kaʻina hana ʻenehana

Hōʻike ʻia ke kaʻina hana o ka molecular sieve sieve desulphurization (desulfurization) skid ma ke kiʻikuhi. Hoʻohana ka ʻāpana i ʻekolu kaʻina hale kiaʻi, hoʻokahi adsorption hale kiaʻi, hoʻokahi hale kiaʻi hou a hoʻokahi hale hoʻomaha. Ma hope o ka wehe ʻana i ka wai hydrocarbon i hoʻokomo ʻia ma o ka mea hoʻokaʻawale kānana hānai, komo ke kinoea hānai i ka molecular sieve desulfurization hale kiaʻi. Hoʻopili ʻia ka wai a me ka mercaptan i loko o ke kinoea hānai e ka molecular sieve e ʻike i ka dehydration a me ka mercaptan adsorption kaʻina. ʻO ke kinoea i hoʻomaʻemaʻe ʻia mai ka dehydration a me ka wehe ʻana o mercaptan e komo i ka kānana lepo lepo huahana no ka wehe ʻana i ka lepo sieve molecular, a laila lawe ʻia e like me ke kinoea huahana.

Pono e hana hou ʻia nā kānana molekula ma hope o ka hoʻopili ʻana i kahi nui o ka wai a me ka mercaptan. Ma hope o ka kānana ʻana i ka lepo kinoea huahana, lawe ʻia kahi ʻāpana o ke kinoea huahana e like me ke kinoea hoʻohou. Ma hope o ka hoʻomehana ʻia ʻana o ke kinoea i 300 ℃ e ka umu wela, ua hoʻomehana ʻia ka hale kiaʻi i 272 ℃ ma o ka molecular sieve desulfurization hale kiaʻi i hoʻopau i ke kaʻina hana adsorption mai lalo a luna, i hiki ke hoʻokaʻawale ʻia ka wai a me ka mercaptan ma ka molecular sieve e hoʻopau i ke kaʻina hana hou.
