Ụlọ ọrụ ngwa ikpe
1. Ụlọ ọrụ kemịkalụ
Nchacha mmanụ: Ngwugwu ọkpọkọ mgbanwe okpomọkụ eji eme ihe na reactor hydrogenation, nke na-eguzogide nchara hydrogen sulfide (njupụta H₂S ≤50ppm).
Mmepụta asịd sulfuric: Iji mee ka gas SO₂ dị elu (≤450℃) jụọ oyi, a chọrọ mkpuchi mgbochi ire ere mgbe a na-eji ígwè carbon.
2. Ike eletriki
