The target of this project work is to identify the main energy dissipative units and to find a possible solution to tackle the recognized troubles of energy efficiency.
A thorough chemical, thermal and electrical performance assessment of corresponding units has made to discover inadequately functioning units. A systematic approach is followed to examine electrical energy consumption of electrical units and compared it with standard and their original design.
Furthermore, causes of dissipation are analyzed. Subsequently, based on the evaluation results, economically and environmentally viable measures have been suggested to enhance the competency of the every unit that forms the whole when combined. In addition to unit wise approach, system based approaches has been adopted on units functioning in integrated manner.

Excerpt from the Book
ENERGY-EFFICIENCY IMPROVEMENT OPPORTUNITIES IN COMPRESSED AIR SYSTEMS
Instrumentation consumes large amounts of compressed air at many individual locations in a textile plant, but these uses are susceptible to leakage. Most such leaks are at threaded connection points, rubber hose connections, valves, regulators, seals, and in old pneumatic equipment. Air leaks from knitting operations are very common and can be quite large; these exact a large invisible cost, and the reduced pressure may impair the operation of the dyeing and finishing machines. Integrated mills that contain knitting operations should check the compressed air systems in knitting as well as in the dyeing and finishing areas.
More than 85% of the electrical energy input to an air compressor is lost as waste heat, leaving less than 15% of the electrical energy consumed to be converted to pneumatic compressed air energy. This makes compressed air an expensive energy carrier compared to other energy carriers. Many opportunities exist to reduce energy use of compressed air systems. For optimal savings and performance, it is recommended that a systems approach is used. In the following, energy saving opportunities for compressed air systems are presented
1. Reduction of demand
Because of the relatively expensive operating costs of compressed air systems, the minimum quantity of compressed air should be used for the shortest possible time, constantly monitored and reweighed against alternatives.
2. Maintenance
Inadequate maintenance can lower compression efficiency, increase air leakage or pressure variability and lead to increased operating temperatures, poor moisture control and excessive contamination. Better maintenance will reduce these problems and save energy.
3. Monitoring
Maintenance can be supported by monitoring using proper instrumentation, including
