The case study discusses the results of energy audits conducted in 13 textile plants from 5 major sub-sectors - spinning, weaving, wet processing, worsted fabric manufacturing and carpet manufacturing in Iran.
Various potential energy efficiency opportunities which could be implemented in these sub-sectors and their cost and energy savings have also been provided.
The study involved visiting the above 13 textile plants (3 from spinning, 2 from weaving, 3 from dyeing, printing and finishing, 3 from worsted fabric manufacturing and 2 carpet manufacturing plants) and conducting walk through audits.The walk through energy audits involved collection of existing data for process and energy utilities. Results showed that in the case of spinning process, energy efficient measures could be adopted for motor driven systems and in the case of other sub-sectors, sustainable measures as an alternative to thermal energy could be considered.
Energy efficient motors
Variable frequency drives
Cooling water recovery in textile dyeing
Energy efficient control for humidification
Bleach bath recovery in textile wet processing
Heat recovery in textile drying and finishing
