The technology development plan for automatic detection and investigation of the total vapor phase mercury emissions from stacks

Absrtact	The implementation period of this plan is from January 2023 to December 2023. The goal of the project is to refer to the relevant technical procedures of Method 30A of the US Environmental Protection Agency to develop and establish an automatic monitoring technology for mercury from domestic stationary sources. Discuss the applicable concentration range, Possible interference and prevention methods, etc.. Develop standard operating procedures for detection methods, and propose an amendment draft that conforms to the National Environmental Research Academy's detection method format. Collect and compile relevant information based on the project objectives, including the current monitoring and control status of domestic and foreign mercury emissions, and understand the current domestic industry characteristics to establish the concentration range that should be explored. Collect and compare relevant specifications for automatic mercury monitoring, explain the existing US Environmental Protection Agency regulations and their interrelationships, and collect discharge pipeline mercury measurement technologies to assist in planning and completing the investigation process for establishing mercury monitoring. We also compare the relevant performance parameters of instruments and equipment on the market related to the verification of this method. This project is completed with reference to the US Environmental Protection Agency Method 30A, including system calibration, interference testing using HgCl2, dynamic spiking, system integrity and drift check. and other standardized tests. It also evaluates the established investigation technology in accordance with the "Precautions for Validation of Environmental Testing Standard Methods" established by the National Environmental Research Academy, and proposes a draft technical standard operating procedure for automatic monitoring and investigation of total gaseous mercury in stacks that complies with the National Environmental Research Academy's method format specifications.
