Discussion on Fugitive Emission Monitoring of Air Pollutants

Construction project completion and acceptance of environmental protection, fugitive emissions of air pollutants monitoring sites based on the Integrated emission Standard of air pollutants (GB16297-1996) and Technical guidelines for fugitive emission monitoring of air pollutants and the relevant technical documents. The main source of fugitive emissions was production equipment obsolete, unreasonable design, operational errors, improper command and poor management. Existing problems: too theoretical, poor operability, from monitoring sites to point measured project location far, representative is not strong. Recommendations that distribution specification,always pay attention to fugitive emissions sampling,scientific and rational way to find the maximum concentration, Monitoring points arrangement as far as possible with less points to achieve better representative monitoring data .

Transmission And Distribution

Natural gas has been forecast to continue grow up to 30% for the next 40 years and will remain as a key energy source. Alongside this projected growth, both the government and the industry have committed to reduce emission reductions. A critical focus is fugitive emissions, which are related to leaks or unintended losses of methane from sources such as hydrocarbon production, processing, transport, storage, transmission and distribution. The need for measuring and monitoring these emissions has been recognised in significant environmental inquiries related to the gas industry, such as the Northern Territory Fracking Inquiry (Pepper et al. 2018) and required in section D of the NT Code of Practice. This study describes an autonomous emission monitoring station developed to address the challenge of characterising temporally varying fugitive methane emissions. It has been designed specifically to tolerate the Australian outback’s extreme climateswhile providing laboratory-grade measurements in real-time at locations where there will be no access to grid power and standard telecommunications. Preliminary results demonstrating the continuous real-time measurements of methane and ethane concentrations of temporally varying phenomena will be presented. Specifically, the detection of methane and ethane concentrations and temporal changes related to bushfire progress will be shown.

Abstract In the wake of Eni's strategy to curb fugitive emissions - in particular methane – an innovative control valve (Clarke Shutter Valve) has been deployed and tested in an Italian Eni facility. This shutter type valve is capable of reducing the fugitive emissions by more than 90%, as well as greatly curbing purchase costs, thanks to an innovative design in bonnet and regulating mechanism. In order to assess the real potentiality of the innovation, four Fisher globe valves and one Fisher V-ball were substituted with the Shutter Valves on different hydrocarbon streams of the Trecate facility (Piedmont), in particular on streams containing oil, gas and corrosive fluids. The valves were monitored for more than a year and fugitive emissions tests have been performed to detect and estimate methane leak rates. Since this represented a first deployment of this technology in Europe, a thorough analysis and technology validation of the valves has been performed. A successful installation and start-up were performed in 3 days by Eni's staff at in February of 2020. The valves were fully operational after the installation and to date no issues have been reported. In order to monitor the valves performances of flow control, continuous data collection on each valve has been implemented, and the analysis performed showed that all valves behave correctly as to Eni's standards. A fugitive emission test that has been performed at the end of 2020 with a certified portable FID/PID analyzer displayed that no methane emissions were detected from the valves. Lastly the one year and half long technology validation concluded that the Shutter Valves are a valid technology for curbing methane emissions from the Oil and Gas plants, and that suggested to qualify the company as Eni partner for control valves. This deployment and field tests, as well as the technological assessment performed by Eni's professionals showed the potentiality of this new type of valves in reducing the methane emissions from the petroleum industry. Understanding the potentiality of intrinsically carbon neutral technology is a crucial step for the mitigation of greenhouse gases emissions and towards the creation of a more environmentally friendly industry.

Dust Collection Efficiency

As the main equipment of flue gas dedusting in coal fired boiler, electrostatic precipitator (ESP) can meet the requirements of emission standard for air pollutants from coal-fired power plants through improving the efficiency of ESP and combining with desulfurization system while not installing wet ESP (WESP). This paper introduces the modifications of ESP cathode structure to improve the efficiency of dust collection by reducing the secondary dust loss at cathode. The application of cathode dust collection provides a reference for the improvement of ESP dust collection efficiency.
