To address the issues of complex equipment
high energy consumption and poor durability in the treatment process of biogas and biogas slurry during anaerobic fermentation of biomass
a new type of integrated ammonia recovery and carbon capture device was designed based on superamphiphobic membrane contactor
which integrated the advantages of direct contact membrane distillation
membrane absorption and other technologies. This device effectively enhances the energy utilization efficiency of the overall process while reducing the complexity of the equipment. The ammonia recovery and carbon capture performances of the integrated device was systematically studied through experiments. Results show that when using ammonia of
low surface tension as feed side
the droplet contact angle of membrane contactor is greater than 150°
and maintains stable operation within 48 h. When operating with a gas circulation process flow and the temperature on the feed liquid side reaches 70 ℃
the ammonia recovery rate of the integrated device is increased from 45% to 97%
and the CO

removal rate exceeds 95%
the CO

thus realizing the high-efficiency resource utilization of wastes in the biogas slurry and biogas treatment processes.
