- The Environmental Managers -
Some Crucial Points
Comprehensive analysis
Starting with an overview
Identifying large energy flows and consumers
Focusing on relevant areas
Main production processes very often well optimised
Concentrating on auxiliary processes

Optimisation – Control Systems
Highly sophisticated control systems installed
Settings do not fit actual demand
(due to adaptations / extensions of plants)
Adjustment of control system to actual demand
Continuous control of correct settings
Retrofit of simple overhead control units
No general rules possible due to many different
types of control systems
Trial and error procedures

Optimisation of Compressed Air
Adaptation of control units
pressure levels
load to idle run ratio
idle run time
Upgrade or change of control units
Compressors with frequency converters
Exploitation of the inevitable waste heat
Refurbishment of the distribution system
Optimisation of pipe diameters

Example: “Free Cooling” of Tanks
Energy Efficiency in IPPC Installations
Andreas Kollegger
14
- The Environmental Managers -
Advantages of “Free Cooling”
Requires only a small share of the electricity
needed for common chillers
Provision of additional annual cooling load
Common chillers can fully be switched off under
certain conditions
Additional safety due to redundancy
