BP34 - Optimize compressed air system

Address: Go Dau District, Tay Ninh Province
Project Summary: In response to the energy efficiency program of Adidas brand, a textile and dyeing enterprise in Tay Ninh Province has implemented the project of pneumatic system improvement. The goal of the project is to reduce energy costs and greenhouse gas emissions.
Year of implementation: 2018

Status before implementation

Compressed air system accounts for about 11% of the factory's total power consumption.

The factories used manual condensate drain valves, causing stagnant water to corrode pipes and joints and damage to the equipment using compressed air; If the drain time is too long, compressed air will be wasted, thereby increasing the power consumption of the air compressor.

 

Manual drain valve in the storage tanks

The air compressor at the dyeing workshop had a pressure set at 7.0 - 8.1 bar, which was high compared to demand. The high pressure setting resulted in reduced compressor efficiency and increased compressed air loss through leak points.

Result

The factory has invested and installed automatic condensate drain valve and timed condensate drain valve.

New condensate drain valve

In addition, the factory has reduced the installed pressure of the dyeing mill air compressor to 5.5 - 6 bar. Savings rate reached about 8.4%.
