Characteristics of Steel Flue Gas Treatment

1、The pollution treatment and control level of the steel industry is similar to other small and medium-sized boilers/kilns, mainly manifested in large changes in operating conditions, frequent start-up and shutdown (limited production), relatively incomplete treatment facilities, and average control level. However, 2+26 cities now attach great importance to it;

2、The flue gas has problems such as high moisture/humidity, low NOx/SO2 concentration, high ammonia escape, high HC (coking leakage, etc.), and high NxOy (oxidation process);

3、The oxygen content in flue gas is high, and the amount of gaseous pollutants in flue gas is relatively large and fluctuates greatly；

4、There are interference gases such as methane and NH3 in the flue gas, which interfere with the monitoring of SO2 by the infrared/DOAS analyzer.

The Problems Faced by Steel Enterprises

1、Enterprise performance level rating urgently requires professional guidance and assistance in organized, unorganized emissions, and clean transportation；

2、Iron and steel enterprises need to strengthen their own management of online monitoring, urgently requiring professional personnel to provide guidance and suggestions on the standardization and operation of online monitoring equipment, as well as supervision and management of third-party operation and testing units, in order to improve their own management level；

3、After completing ultra-low emissions, enterprises need to ensure the authenticity, accuracy, and completeness of online monitoring data to self verify their innocence；

Solution Recommendation

1、Overall consulting services：

      a、Conduct inspections on the installation standardization of online equipment for pollution source discharge outlets in steel enterprises；

      b、Production/governance/online/manual comparative monitoring, four simultaneous data analysis；

      c、Supervised assessment and evaluation of third-party operation and maintenance/testing units；

      d、Customized professional technical training services；

2、Deep detection service： 

      a、Conventional gaseous pollutant comparison testing；

      b、Ammonia escape, CPM deep testing； 

3、Data normalization and full compliance plan

      a、Chunxi Co., Ltd. provides specialized and customized solutions (ammonia removal and dehumidification pre-treatment system) based on the on-site investigation of problems and the issue of non-compliance throughout the entire process；

      b、Complete on-site installation and debugging to ensure the correct implementation of solutions and achieve corresponding results；

      c、Continuously track the operational status of the system to ensure that issues have been resolved；

      d、Ensure that online monitoring data is "true, accurate, and complete", and verify the ultra-low emission effect。

       Recommend using Chunxi PreGASS ®- 2500 ammonia removal pre-treatment system and PreGASS ®- 9500 sample gas pre-treatment system solves the problems of ammonium salt crystallization and liquid water precipitation respectively, retaining the components to be analyzed, providing guarantee for accurate monitoring, enabling the CEMS system to operate for a long time, stably, and reliably, and truly reflecting the operation of the process.。
