A kind of biogas slurry decarbonization and ammonia removal method and system |
| abstract |
The present application provides a method and system for decarbonization and deamination of biogas slurry. The method includes: preheating the biogas slurry to be treated and then sending it to the upper part of a stripping tower; sending the stripping steam to the lower part of the stripping tower, and the stripping tower The steam and the preheated biogas slurry to be treated conduct countercurrent heat and mass transfer, and the carbon dioxide and ammonia gas in the preheated biogas slurry to be treated are stripped into the gas phase to obtain ammonia-carbon mixed steam; /or the spraying agent is sent to the upper part of the stripper, and the biogas slurry to be treated and/or the spraying agent and the ammonia-carbon mixed steam carry out counter-flow heat and mass transfer to remove the ammonia gas in the ammonia-carbon mixed steam , so that carbon dioxide is enriched at the top of the stripper, ammonia is enriched in the middle of the stripper, and the spray agent includes fresh water. The biogas slurry decarbonization and ammonia removal method and system of the present application can realize the efficient removal of ammonia carbon in the biogas slurry and the recovery of carbon dioxide and ammonia gas. |
