Desulfurization and denitrification agent and application thereof

Abstract

A desulfurization and denitrification agent and application thereof are provided, belonging to the fields of flue gas purification and purified product recycling. In the present disclosure, an imidazoline amine oxide is used as a desulfurization and denitrification agent, which can oxidize NOx and SOx into HNO3 and H2SO4. Meanwhile, after the agent is reduced, double bonded tertiary nitrogen atoms in the agent can be used as a base for neutralizing H2SO4 and HNO3. In addition, in the present disclosure, the imidazoline amine oxide is used as the desulfurization and denitrification agent for two-stage desulfurization and denitrification of flue gas. Waste liquid produced after the reaction is injected as foaming acid liquid into carbonate and tight sandstone reservoirs, and slowly hydrolyzed into H2SO4, HNO3, and HF at the reservoir temperature, and the produced acid reacts with the reservoirs to augment production and injection of the reservoirs.
