ʻO ka hoʻoheheʻe ʻana i ka Ammonia i ka hydrogen

ʻO ka wehewehe pōkole:

ʻAmonia Decomposition

ʻO ka hana hydrogen o ka hoʻoheheʻe amonia e lawe i ka ammonia wai ma ke ʻano he mea maka.Ma hope o ka vaporization, loaʻa ke kinoea hui pū me 75% hydrogen a me 25% nitrogen ma ka hoʻomehana a me ka decomposition me ka catalyst.Ma o ke kaomi swing adsorption, hiki ke hana hou ʻia ka hydrogen me 99.999% maʻemaʻe.

ʻAmonia Decomposition

ʻO ka hana hydrogen o ka hoʻoheheʻe amonia e lawe i ka ammonia wai ma ke ʻano he mea maka.Ma hope o ka vaporization, loaʻa ke kinoea hui pū me 75% hydrogen a me 25% nitrogen ma ka hoʻomehana a me ka decomposition me ka catalyst.Ma o ke kaomi swing adsorption, hiki ke hana hou ʻia ka hydrogen me 99.999% maʻemaʻe.

Ke Kumu o ka hoʻoheheʻe ʻana i ka Ammonia

ʻAmoni ʻAmona wai
ʻO ka wai amonia e kahe ana mai loko mai o ka ʻōmole amonia e komo mua i ka vaporizer amonia.Ke hoʻohana nei i ka hoʻomehana wai ʻauʻau i ka vaporization, a ʻo ka vaporizer he mea hoʻololi wela o ka pepa-pepa.Hāʻawi ʻia ʻo Ammonia i ka ʻaoʻao o ka paipu, a ʻo ka ʻaoʻao pūpū he wai wela i hoʻomehana ʻia e ka mea hoʻomehana uila.ʻO ka wai wela a me ka wai amonia e hoʻololi i ka wela e hoʻoheheʻe i ka ammonia wai i ka ammonia kinoea me 1.5MPa a me 45 ℃.Hoʻemi ʻia ka ammonia kino mai ka 1.5MPa a i ka 0.05Mpa e ke kaomi hoʻohaʻahaʻa i ka valve e hoʻololi i ka wela me ke kinoea wela kiʻekiʻe mai ka umu decomposition, a laila komo ka ammonia preheated i ka umu wela decomposition kiʻekiʻe.

ʻAmonia Decomposition
Hoʻokumu ʻia ka umu hoʻoheheʻe me ka umu uila a me ka liner kapuahi decomposing.Aia ka umu uila i nā mea hoʻomehana uila, nā mea refractory, nā mea insulation thermal, thermistors a me nā mea hoʻokele wela uila.Ma ke ala, ʻo nā mea hoʻomehana uila nickel chromium alloy Cr20Ni80, ʻo ia ka mea hoʻomehana uila maikaʻi loa.Hana ʻia ka mea insulation thermal me ka alumini silicate fiber brick kaulana.
ʻO ka liner kapuahi decomposition ka mea nui o ka decomposition amonia.Māhā ʻia ʻo Ammonia i loko o ka hui ʻana o ka hydrogen nitrogen i ka wela kiʻekiʻe me ka catalyst i loko o ka liner decomposition furnace.Hiki i ka liner furnace ke hoʻomanawanui i ka mahana wela lōʻihi o 900 ℃ a me ka corrosion mai ka amonia.No laila, e hoʻohana ana i ke kiʻekiʻe wela wela e like me ka mea hoʻoheheʻe kapuahi, a ʻo ka liner kapuahi e hana i ka U-like me ka nickel catalyst kiʻekiʻe.Hoʻoheheʻe ʻia ʻo Ammonia i loko o ke kinoea hui ʻia me 75% hydrogen a me 25% nitrogen me ka catalyst ma lalo o ka wela kiʻekiʻe.
ʻO ka hoohalike kemika ʻo 2NH3 → 3H2 + N2 - Q

PSA Hoʻomaʻemaʻe / PSA Hydrogen Production
Hele ke kinoea hui ʻia i loko o ka mea hoʻololi wela a me ka wai anuanu, a laila komo i ka hoʻomaʻemaʻe hydrogen no ka hoʻomaʻemaʻe.ʻO ka hoʻomaʻemaʻe i haku ʻia me ka deaerator, cooler, molecular sieve adsorption dryer, hui valve a me ka mana uila.
E like me ke kumu o ke kaomi swing adsorption (PSA), aia ʻelua molecular sieve adsorption dryers, a ua hana hou ʻia nā molecular sieve adsorption dryers.Hoʻokahi ka adsorbing i nā haumia a ʻo kekahi e hoʻopau a hoʻokuʻu i nā haumia.

Kaʻina Kaʻina o ka ʻAmonia Decomposition

ʻO Amonia i koe 0.1%
Ke kahe o ka hydrogen 1~1000Nm3/h

Nā hiʻohiʻona o ka hoʻoheheʻe ʻana i ka Ammonia

☆ ʻO ke kumukūʻai haʻahaʻa, ka hoʻohana ʻana i ka ikehu a me ka hoʻopukapuka kālā, ka liʻiliʻi liʻiliʻi a me ka hana kiʻekiʻe.
☆ Hoʻomaluʻia ka mahana e ka mea hoʻolālā wela a hoʻoponoponoʻia ke kahe e ka valve.No laila, hilinaʻi ka hana.
☆ E hoʻohana i ka mea hoʻoheheʻe kiʻekiʻe, ke kila kuhili ʻole wela, nā mea hoʻomehana uila nickel chromium a me nā kiwi kila kuhili.
☆ Maʻalahi e hoʻohana a hoʻokomo me ka ʻole o ke kūkulu ʻana i ke kapikala, ka hoʻolālā paʻa a me ka wahi papahele liʻiliʻi ma ke ʻano he ʻano hoʻohui skid mounted.
☆ Hiki ke hoʻohana manuahi ʻia ke kinoea i loko o ka pae hana kinoea i helu ʻia me ka palekana kiʻekiʻe.ʻO ka maʻamau, ʻaʻohe pono e mālama i ka hydrogen i loko o ka pahu mālama.
