Sodium Hydrosulfide a Wɔtew Ho: Akyigyina ne Nhumu

Wɔ petroleum ne nnuruyɛ mu no, akwan a wɔfa so yɛ nneɛma a wɔde yɛ nneɛma te sɛ vacuum distillation ne catalytic cracking taa ma mframa a ɛyɛ acid ba. Saa acidic mframa yi taa yɛ 85%–95% hydrogen sulfide (H2S), 3%–10% carbon dioxide (CO2), 2%–5% organic gas, ne 0.5%–3% nneɛma afoforo.

Nnwumakuw nketewa ne akɛse a wɔyɛ nneɛma a wɔde yɛ nneɛma foforo taa yɛ saa mframa a ɛyɛ acid yi ho adwuma denam sodium hydroxide (NaOH) aduru a ɛyɛ 30% a wɔde twetwe so. NaOH no ne H2S yɛ adwuma ma ɛyɛ sodium hydrosulfide a wɔde yɛ aduru (NaHS) (NaHS) no. Sɛ NaHS dodow a ɛwɔ aduru no mu no du 30% a, aduru no fa dodow nhyehyɛe bi mu. Sɛ wɔma nsuo fi mu na wɔde hyɛ mu wie a, NaHS a ɛwɔ mu no kɔ soro kodu 70%, na afei wɔtwitwa NaHS a wɔabɔ no mu ma ɛyɛ no flakes.

Nanso esiane sɛ CO2 wɔ mframa a ɛyɛ acid no mu nti, efĩ te sɛ sodium carbonate (Na2CO3) ba bere a wɔreyɛ aduru no, na ɛma NaHS ade no ho tew.

Bio nso, sɛ wɔde open-drum flakers di dwuma de twitwa NaHS a ayɛ hyew no mu a, NaHS no taa ne oxygen a ɛwɔ mframa mu no yɛ adwuma, na ɛyɛ sodium thiosulfate (Na2S2O3), a ɛtaa sɛe na ɛyɛ den sɛ wɔbɛkora so. Open slicing nso ma mframa a ɛhyɛ abufuw fi mu ba, na ɛde efĩ ba baabi a wɔyɛ nneɛma no.
