Emerson extends PlantWeb to previously unreachable data for improved availability and operational performance.
The project forms part of the Scottish Water overall strategy to invest in new technologies and advanced methods of beneficially recycling sewage sludge, in line with the EU Directive prohibiting the disposal of sludge at sea.
The sludge dryers are operated to ensure that the oxygen levels are kept below the point at which the gases and the dust in the dryer atmosphere would allow combustion.
This essential measurement using Rosemount Analytical World Class 3000 oxygen analysers enables the sludge dryers to operate safely.
The Daldowie sludge drying plant will process the entire sewage output from the Greater Glasgow area, a population of 1 million people, creating up to 65000 tonnes per annum of waste derived fuel (WDF).
The WDF sludge granules have a similar energy content to brown coal, and can be burned at power stations for power generation.
The World Class 3000 oxygen analysers were chosen based on their proven performance on this application in other UK plants.
The analysers demonstrated their tolerance to the dirty, dusty, humid and sometimes wet conditions experienced in the drying ovens.
More usually applied to flue gas monitoring systems for combustion control, the standard analogue output calibration range covers 0-21% Oxygen, and the analyser has three relay alarm outputs at adjustable concentration levels.
PlantWeb technology will be used to assist with remote calibration checking and performance tracking.
The Rosemount Analytical analysers provide HART digital communications, accessible from the control room current output loop.
Current diagnostic data from the microprocessor intelligence in the analyser will be collected by the AMS Suite: Intelligent Device Manager to enable predictive maintenance and calibration when needed. Request a free brochure from Emerson Process Management ...
