1.Petroleum, petrochemical lako, e like me reactors i ka petrochemical lako, etc.
2.Storage a me nā mea halihali no ka sulfuric acid, e like me nā mea hoʻololi wela, etc.
3.The flue kinoea desulfurization mea i loko o ka mana mea kanu ua nui hoʻohana 'ia i loko o: ka hale kiaʻi kino o ka absorption hale kiaʻi, ka flue, ka pani, nā mea i loko, ka'ōhū'ōnaehana, etc.
4.Scrubbers a me nā mea pā i loko o nā ʻōnaehana hoʻomaʻamaʻa waikawa organik.
5. Nā mea hoʻomaʻamaʻa wai kai, nā mea hoʻololi wela o ke kai, nā lako ʻoihana pepa, sulfuric acid, nā mea hana waikawa nitric, ka hana ʻana i ka waikawa, ka lāʻau lapaʻau a me nā mea kemika ʻē aʻe, nā ipu kaomi, nā meaʻai.
6.Pharmaceutical mea kanu: centrifuges, reactors, etc.
7. Mea kanu meaʻai: nā kīʻaha soy, ka waina kuke, nā ipu paʻakai, nā mea hana a me nā lole.
ʻO 8.904L ka papa kila kūpono no ka mea hoʻoheheʻe ikaika o ka dilute sulfuric acid.
