Product-to-product heat recovery
Wastewater, sewage, effluents and sludge are useful sources of energy with the potential to heat (or in some circumstances cool) other products or materials in industrial processes. The DTR Series of double tube heat exchangers from HRS Heat Exchangers is designed to maximise direct (product-to-product) energy recovery from such low viscosity materials, allowing valuable heat to be recaptured before the effluent enters final treatment or is discharged to the environment.

ICK’s innovative new FTMg thermal flow meter simultaneously measures gas flow, pressure and temperature then computes
the combined values to detect leaks in pneumatic systems and monitor compressed air energy consumption in real time. The SICK FTMg Thermal Flow Meter’s on-board algorithm uses
the flow, pressure and temperature values to calculate the energy of gas passing through the flow channel in kWh. By comparing to the electrical power demand of the compressor, the SICK FTMg can accurately detect changes in the efficiency of a pneumatic system. As a result, the compact and easy-to-use device promises major benefits for improved process efficiency of machines, as well as to achieve plant-wide savings as part of ISO EN 50001-compliant energy management systems. “Compressed air loss is a major source of wasted energy in most
production plants, quite easily amounting for more air lost through leakages than is used for the process itself,” says Darren Pratt, SICK’s UK product manager for Industrial Instrumentation. “Undetected leaks in pneumatic systems can lead to unexpected machine failures, or to gradual degradation in product quality. “SICK’s first gas flow meter for factory automation has entered
the market with an exciting innovation that breaks new ground, especially for minimising the operating costs associated with producing, supplying and distributing compressed air.

“This neat little sensor has a real-time graphic display for
trending of measured values on the device itself. At the same time, it opens up transparency for production and maintenance teams to monitor, trend and record the operating efficiency and energy consumption of their pneumatic systems through industrial control, IT or cloud-based systems. Using the FTMg, targeted interventions can be planned to identify and eliminate leaks in machine cell compressed air systems, for example.”
