Flow Measurement for Emissions Monitoring

Emissions monitoring is a major concern at chemical process industries (CPI) facilities. A number of factors are elevating the importance of proper monitoring, and amplifying the consequences of failing to do so reliably and accurately. These factors include global climate-change mitigation efforts, company-based environmental, social and governance (ESG) objectives and a new pollution-enforcement regime at the U.S. Environmental Protection Agency. Among the implications for the emphasis on emissions monitoring is a heightened importance to accurately measure gas flow for high boiler and process-heater efficiency. In emissions control and combustion applications, flowmeters measure the flow of fuel gas and air to combustion burners within various types of process equipment. Sierra Instrument’s whitepaper, “Understanding Flow Measurement for Emissions Monitoring,” discusses regulatory requirements and various flowmeter technologies, as well as the strengths and weaknesses of each.
