n “Pre-SCR Injection of Sodium Sorbents,” presented at EUEC 2018, trona and sodium bicarbonate treatment of flue gas emissions are reviewed in two case studies. The first focuses on a power plant with a medium sized boiler.
The engineers at a municipal wastewater treatment utility were expanding their biogas digester system and were seeking an improvement over their existing, maintenance-intensive flow metering technology. They needed to measure the amount of gas contained within a gas bag as well as the flow rate of the gases traveling from the gas bag system into a co-generation power system.
One of the most common processes in wastewater treatment is the activated sludge method, which biologically treats the wastewater through the use of large aeration basins. This process requires the pumping of compressed air into the aeration basins where a diffuser system ensures the air is distributed evenly for optimum treatment. The energy needed to provide compressed air is a significant cost in the operation of a wastewater treatment plant.
ST100 is an all-new thermal dispersion technology gas flow meter that combines feature- and function-rich electronics with the industry’s most advanced flow sensors to achieve a truly state-of-the-science flow metering solution for industrial processes and plant applications.
FCI’s MT Series Multipoint Mass Flowmeters are ideal for today's most challenging industrial air or gas handling applications and continuous emissions monitoring systems (CEMS)
To meet China’s growing need for electric power generation, the Guohua Ninghai Power Plant has a total planned operating capacity of 4 x 600 MW [Phase 1]. The plant is located south of Shanghai in Ninghai township, Ningbo city, Zhejiang province and serves the electric power needs in the region.
The new FiltraFast™ extreme-rate compressible media filter recently developed by SUEZ achieves up to 10 times the hydraulic loading rate compared to conventional filters, within a compact footprint. FiltraFast™ is customizable to meet specific requirements of different applications, including process water and wastewater treatment.
FiltraFast™ is a high-rate downflow gravity or pressure filter that uses a unique compressible media. The filter only uses hydraulic loading to create the required media porosity without any mechanical compressing devices. A proprietary backwash sequence enables maximum recovery, extends media life, and limits energy consumption. This process 1) significantly reduces the footprint compared to sand filters, and 2) reduces maintenance and replacement costs required by disc filters, and other compressible media filters.
Power plants generating steam balance cost, efficiency and reliability with environmental considerations while supplying energy to the world. Degasified water plays a critical role in generating the energy used to heat and cool homes and businesses while protecting vital capital equipment.
This white paper describes the three steps for deploying condition-based monitoring on critical electrical power assets which will lead to a proactive – and eventually, predictive – maintenance strategy
