In the production process of energy chemical industry and semiconductor industry, some gas sources, such as waste gas, gallium nitride epitaxial process tail gas, contain more or less ammonia, which needs to be recovered. Based on the technical requirements, our company has developed with efficient water absorption for making strong aqua ammonia exhaust technology, multiple projects successfully applied at home, effectively solve the traditional sulfuric acid washing sulfuric acid consumption of large, high operating cost and the difficulty of by-product ammonium sulfate sales, series of problems.

Technical features and advantages

µ It is advanced and mature technology, stable and reliable operation

µ The water washing ammonia absorption process can be flexibly configured according to the working conditions, with the optimal investment and energy consumption

µ It has independently developed GXR high efficiency absorption reactor with fast absorption mass transfer rate and high purification degree

µ The utilization of ammonia tail gas to produce concentrated ammonia water products has good economic benefits

Application field

T Recovery and utilization of ammonia gas in gas containing ammonia, such as waste gas, gallium nitride epitaxy process tail gas
