Panlinis na Sodium Hydrosulfide: Background tan Insights

Diad industriya na petrolyo tan kemikal, saray proseso na refinery a singa say vacuum distillation tan catalytic cracking et kaslakan ya mamapawala na acidic gases. Sarayan acidic gases et kaslakan ya tugyopen na 85%-95% hydrogen sulfide (H2S), 3%-10% carbon dioxide (CO2), 2%-5% organic gases, tan 0.5%-3% ya arum nin kabiangan.

Saray melag tan kalatnaan iran refinery et kaslakan ya mantratrato ed sarayan acidic gases diad panamegley na 30% sodium hydroxide (NaOH) ya solusyon. Say NaOH et onreak ed H2S pian manporma sodium hydrosulfide (NaHS). No say konsentrasyon na NaHS ed solusyon et onsabi ed 30%, say solusyon et ondalan ed proseso na konsentrasyon. Kayari na dehydration tan konsentrasyon, say NaHS content et ondarakel ya anggad 70%, insan say tinunaw ya NaHS et i-slice ed saray flakes.

Balet, lapud saray asidon gas et walaan na CO2, saray dutak a singa say sodium carbonate (Na2CO3) so napapawala legan na panagtambal, ya mamapaabeba ed inkapuro na produkto na NaHS.

Niarum ni, no usaren so open-drum flakers pian na-slice so tinunaw ya NaHS, say NaHS et onkikiwas ed oxygen ed dagem, ya manporma na sodium thiosulfate (Na2S2O3), ya mainomay ya naderal tan mairap ya isimpen. Say open slicing et mangibubuga met na makapaermen iran gas, ya mandutak ed kaliberliber na produksyon.

Pindoten dia pian makala na diskwento parad sodium hydrosulfide, wala ray sorpresa.
