Removal of Sulfur Compounds from Gas - A simplified explanation of the abstract
This abstract first appeared for US patent application 17958938 titled 'Removal of Sulfur Compounds from Gas
Simplified Explanation
The system and method described in the patent application involve removing sulfur compounds from gas using a non-thermal plasma catalytic unit. The process includes discharging tail gas from a sulfur recovery unit to the NTP catalytic unit, where oxidant is provided to the NTP reactor to create oxidative reactive species. These species then convert the sulfur compounds with the help of a catalyst into sulfur oxides, which are then absorbed into water in a quench tower. The treated tail gas is discharged with only small amounts of sulfur compounds remaining.
- Discharging tail gas with sulfur compounds from a sulfur recovery unit to a non-thermal plasma catalytic unit
- Providing oxidant to the NTP reactor to create oxidative reactive species
- Converting sulfur compounds into sulfur oxides using the oxidative reactive species and catalyst
- Absorbing sulfur oxides into water in a quench tower to treat the tail gas

Original Abstract Submitted
A system and method for removing sulfur compounds from gas, including discharging tail gas having sulfur compounds from a sulfur recovery unit (SRU) to a non-thermal plasma (NTP) catalytic unit including an NTP reactor, providing oxidant to the NTP reactor and placing the oxidant in an NTP state in the NTP reactor to give an oxidative reactive species formed from the oxidant, converting (oxidizing) the sulfur compounds with the oxidative reactive species and catalyst in the NTP catalytic unit into sulfur oxides (SO) to discharge the tail gas as treated having the formed SOwithout the sulfur compounds that were converted. The SOis absorbed into water in a quench tower to give the tail gas beneficially having only small amounts (e.g., less than 200 ppmv) of sulfur compounds. SOmay be degassed from water discharged from the quench tower and sent to the SRU furnace.
