Feature Energy Management Automation for waste to energy facility
Emerson’s digital automation technology is being used to provide flexible and accurate control to a new waste and biomass fed power station at Morcenx in southwestern France
E
merson Process Management’s dig- ital automation technology is being used by CHO-Power, part of the Europlasma Group, to control a new waste and biomass fed power sta- tion at Morcenx in southwestern France. By providing flexible and accu- rate control of the gasification process, Emerson’s Ovation expert control system is enabling the plant to operate at maximum efficiency.
The new Morcenx gasification facility will generate 12MW of power from 150 metric tonnes per day of industrial and wood waste. The effi- cient use of waste and biomass fuel helps the plant support European energy guidelines, promoting the use of continuous source renewable energy with low CO2
emissions. Start-
up was in autumn 2012, and the plant was commissioned to the grid at the beginning of 2013.
The Morcenx power station is the first of its type to use a highly effi- cient gasification principle based on patented ‘Turboplasma’ equipment to transform waste into syngas. The 1,200°C temperatures generated from the plasma torch produce a very pure syngas that is used to drive the tur- bine and generate electricity. In addi- tion, 18MWth of hot water from the cooling system is used to heat a veg- etable greenhouse and a wood drier. “We selected Emerson’s Ovation system because it provides the levels of flexibility and control needed to cope with the varying

characteristics of biomass fuels,” said Yannick Ferriere, project man- ager, CHO Power. “Also critical was Emerson’s extensive project man- agement experience with biomass power generating plants, as well as its technical support including engineering, configuration of the Ovation system, training, start-up assistance and maintenance.”
Everything’s under control The Ovation system, together with AMS Suite predictive maintenance software and smart instrumentation, is part of Emerson’s PlantWeb digital plant archi- tecture that provides both advanced control and asset management capabil- ity for the Morcenx facility.
The Ovation system will perform data acquisition and monitor and control all major plant components to provide improved unit stability, responsiveness and thermal efficien- cies, tighter overall control of plant operations, and a more concise view of key plant and turbine parameters. The system provides embedded advanced algorithms and proven control routines that continually adjust the combustion process to compensate for the varying charac- teristics of biomass fuels. This max- imises both boiler and plant efficiency. The Ovation system inter- faces with the GE steam turbine, gas treatment system and gas engine using Profibus-DP communications. An Ovation SIS (safety instru-

mented system) provides SIL-3 pro- tection for the boiler systems. Complying with the stringent inter- national standard IEC 61511, Ovation SIS employs digital intelligence and diagnostics to provide an integrated complete safety loop approach that helps increase process availability, reduce lifecycle costs and ease regu- latory compliance.
Emerson also provided a broad range of instrumentation for the power station, including Rosemount temperature, pressure and flow trans- mitters, Fishe control valves, and Rosemount Smart Wireless tempera- ture transmitters. AMS Suite soft- ware will enable maintenance and operations personnel to predict equipment issues to better maintain and protect the machinery.
Proud to be involved “We are delighted that Europlasma has chosen our automation technologies for this innovative power facility,” said Bob Yeager, president of the Power & Water Solutions business unit of Emerson Process Management. “Our technologies, services and sup- port have made a significant contribu- tion to this project, which will develop into a key part of Europe’s renewable generating capacity.”
A detailed market study by CHO- Power shows that 650 new advanced gasification power plants will have to be built in Europe by 2030 to meet EU renewable energy targets. Of these, 107 would be required in the UK and a fur- ther 126 in France.
