Biogas i ka mea kanu CNG/LNG

Biogas i CNG/LNG wehewehe

Ma o ke kaʻina hana hoʻomaʻemaʻe e like me ka desulfurization, decarbonization a me ka dehydration o ka biogas, hiki ke hana ʻia ke kinoea kūlohelohe maʻemaʻe a me ka pollution-free, kahi e hoʻonui nui ai i kona waiwai calorific combustion. Hiki i ke kinoea huelo decarbonized ke hana i ka carbon dioxide, i hiki ke hoʻohana pono ʻia ka biogas, a ʻaʻole e hoʻohua i ka pollution lua.

E like me nā koi o ka huahana hope loa, hiki ke hana ʻia ke kinoea kūlohelohe mai ka biogas, hiki ke lawe pololei ʻia i ka pūnaewele paipu kūlohelohe e like me ke kinoea kīwila; A i ʻole CNG (compressed natural gas no nā kaʻa) hiki ke hana ʻia i wahie kaʻa ma ke kaomi ʻana i ke kinoea kūlohelohe i 20 ~ 25MPa; Hiki ke hoʻoheheʻe ʻia ke kinoea huahana a hoʻohua i ka LNG (liquefied natural gas).

ʻO ke kaʻina hana o ka biogas i CNG he ʻano hana hoʻomaʻemaʻe a me ke kaʻina hana kaomi hope.
1. ʻO ka nui o ka sulfur maʻiʻo e hōʻino i nā lako a me nā paipu a hoʻemi i ko lākou ola lawelawe;
2. ʻO ka nui o ka CO₂, ka emi o ka calorific waiwai o ke kinoea;
3. No ka mea, hana ʻia ka biogas ma kahi ʻano anaerobic, ʻo ka O₂ʻAʻole e ʻoi aku ka ʻike ma mua o ka maʻamau, akā pono e hoʻomaopopo ʻia ʻo ka O₂ʻAʻole e kiʻekiʻe ka ʻike ma mua o 0.5% ma hope o ka hoʻomaʻemaʻe ʻana.
4. I ke kaʻina hana o ke kinoea pipeline halihali, ka wai condenses i ka wai ma haʻahaʻa wela, e hoemi i ke kea-sectional wahi o ka pipeline, hoonui i ke ku e a me ka ikehu hoʻohana i loko o ka lawe kaʻina hana, a hiki i ka hoʻokuʻu a ālai i ka pipeline; Eia kekahi, ʻo ka hele ʻana o ka wai e hoʻolalelale i ka corrosion o ka sulfide ma nā mea hana.

Wahi a nā palena kūpono o ka biogas maka a me ka nānā ʻana i nā koi huahana, hiki i ka biogas raw ke desulfurization, ka maloʻo pressurization, decarbonization, CNG pressurization a me nā kaʻina hana ʻē aʻe, a hiki ke loaʻa ka huahana: CNG compressed no ke kaʻa.
