Utilities such as Steam, Compressed Air and Refrigeration & Air Conditioning are very crucial for the process. These utilities are often very expensive to operate and form a substantial part of the total energy cost. They also have a major influence on the processes that use them, often affecting the throughput rates, quality and the cost of manufacture.
A common, but mistaken belief among many operating people in the industries that compressed air is free. This leads to misuse of this expensive, perhaps the most expensive utility in the plant. In many compressed air systems only 10% of the actual energy input to the compressor reaches the points of use because of a number of inefficiencies in the compressed air system.
The following measures describe some of the opportunities for energy cost reduction in compressed air systems:
- Sequential Controls
- Leakage Control
- Optimising generation pressures
- Efficient Generation
- Segregation of High Pressure & Low Pressure Lines
- Storage & Distribution
