Discussion on the Recycling Process of Biomass Gasification Washing Effluent
A large amount of ammonia-containing effluent is generated in the process of biomass gasification,however,it is difficult for the conventional ammonia stripping process to adapt to the working conditions of high-concentration NH3-N effluent,hence the conventional process must be optimized.Taking the distilled ammonia stripping process of syngas washing effluent of a methanol plant as an example,the ammonia stripping process is simulated by the software ASPEN PLUS,and the design parameters are optimized.The simulation findings show that the effluent quality and by-product purity are sig-nificantly improved by adopting the optimized process flow,and w(NH3)in the concentrated ammonia reaches 22%.
