A scavenger comprising a formaldehyde sulfoxylate may be used to scavenge hydrogen sulfide (HS) from systems that are brine or mixed production. Suitable formaldehyde sulfoxylates include, but are not necessarily limited to, sodium formaldehyde sulfoxylate, zinc formaldehyde sulfoxylate, and calcium formaldehyde sulfoxylate, potassium formaldehyde sulfoxylate, magnesium formaldehyde sulfoxylate, iron formaldehyde sulfoxylate, copper formaldehyde sulfoxylate, alkene aldehyde sulfoxylates, and combinations thereof.

Application of formaldehyde sulfoxylates for scavenging HS

Treatment of hydrocarbon streams, e.g. gasoline, with basic ionic liquids (ILs), results in reduction of the sulfur compounds such as HS thiophenes, disulfides, thioethers, and/or mercaptans that are present to remove these compounds. The IL is a quaternary ammonium compound having the formula RNXor XRNR'NRX, where R is independently an alkyl group, an alkylbenzyl group, a hydroxyalkyl group, or a hydroxyalkylbenzyl group, and R is straight or branched and has 1-22 carbon atoms, R&#x2032; is a straight or branched alkylene or oxyalkylene having 1 to 10 carbon atoms, and where Xcan be hydroxide, carbonate, alkylcarbonate, bicarbonate or alkoxide, where the alkyl group of the alkylcarbonate or alkoxide, if present, is straight or branched and has 1 to 8 carbon atoms. The ILs can be used in applications where liquid or gaseous hydrocarbon fluids are treated by direct injection or by extraction.
