8 Industrial Energy What is it? Wikipedia: The goal of efforts to reduce the amount of energy required to provide products and services. Industrial concerns: No influence on product quality No influence on production capacity No influence on existing organizational structures In conformity with legislation In conformity with health, safety and environmental regulations With payback < 3 years

9 Industrial Energy How do we handle it? Energy Monitoring Process Batch vs. continuous processes E.g. drying chambers vs drying tunnels Different products on 1 production line E.g. white chocolate vs. dark chocolate High number of operational hours per year E.g. 24/24, 5/7 As close as possible to the consumers E.g. on product side of heat exchangers

10 Industrial Energy How do we handle it? Energy Monitoring HVAC Less critical Less operational hours per year (weather influences) As close as possible to the consumers Result Heat consumption profile per user for different products kw, Temperatures Refrigeration consumption profile for different products kw, Temperatures

11 Industrial Energy How do we handle it? Basic Engineering Reduction of energy consumption Re-use of waste heat/refrigeration Within the system Towards other systems Efficient distribution/transport of the required energy Efficient local production of the net required energy

12 Industrial Energy How do we handle it? Basic Engineering Reduction of energy consumption of users Typical examples: insulation, shut down, compartments, Process tuning Product-specific setpoints Uniform quality Low temperature heating High temperature cooling Maximization saturation process streams

13 Industrial Energy How do we handle it? Basic Engineering Re-use of waste heat/refrigeration Direct systems Recirculation of process streams Indirect systems Heat exchangers (plate, tube, shell, glass, ) Condensors Rotating wheel.

14 Industrial Energy How do we handle it? Basic Engineering Re-use of waste heat/refrigeration Indirect systems Active systems Vapor compression cycles (heat pump) Conversion systems RC / ORC in CHP-modus Ab(d)sorption chillers

15 Industrial Energy How do we handle it? Basic Engineering Efficient distribution/transport of energy Variable speed drives Fans Pumps Integrated automation systems Positive effect on efficiency of energy-production/recovery

16 Industrial Energy How do we handle it? Basic Engineering Efficient local production/recovery of energy free energy recovery Solar / Wind / Biomass Free cooling Buffering Cogeneration (engines, turbines, )
