Model TWIN-NOx -SNCR Technology

With the TWIN-NOx process, the different reaction behaviors of urea solution and ammonia water are specifically applied. Both reducing agents are used alternately or as a mixture, depending on the operating conditions. The respective advantages can thus be used alternatively or in combination, depending on requirements, in order to expand or shift the effective temperature range for the NOx separation and thus to significantly improve the performance of the SNCR process.
