A method for treating sulfur contaminants is provided. The method comprises introducing a methylmorpholine-N-oxide solution to a vessel, wherein the vessel comprises a water layer and a gas layer, wherein the water layer and the gas layer comprise the hydrogen sulfide; introducing methylmorpholine-N-oxide into the water layer; and treating the water layer by allowing the methylmorpholine-N-oxide to react with the hydrogen sulfide.

An exhaust gas processing system having excellent durability and good desulfurization and denitration efficiency is provided to efficiently recover carbon dioxide with high purity and reduced processing costs. The exhaust gas processing system has: a desulfurization unit removing sulfur oxides from the exhaust gas by the limestone-gypsum method; a denitration unit arranged downstream of the desulfurization unit to remove nitrogen oxides from the exhaust gas; a carbon dioxide recovery arranged downstream of the denitration unit to recover carbon dioxide from the exhaust gas; and an oxygen supply unit supplying to the desulfurization unit with a faction of the recovered gas from the carbon dioxide recovery unit as oxygen source. An analyzer is used to monitor the purity and recovery ratio of the carbon dioxide recovered, and the supplied ratio of recovered gas is adjusted, based on the monitored purity and recovery ratio.

A carbon dioxide capture facility is disclosed comprising packing formed as a slab, and at least one liquid source. The slab has opposed dominant faces, the opposed dominant faces being at least partially wind penetrable to allow wind to flow through the packing. The at least one liquid source is oriented to direct carbon dioxide absorbent liquid into the packing to flow through the slab. The slab is disposed in a wind flow that has a non-zero incident angle with one of the opposed dominant faces. A method of carbon dioxide capture is also disclosed. Carbon dioxide absorbing liquid is applied into packing in a series of pulses. A gas containing carbon dioxide is flowed through the packing to at least partially absorb the carbon dioxide from the gas into the carbon dioxide absorbing liquid.
