Compressed Air System Performance Assessment
Client plant — compressed air system study
- 223 kW
- Potential for energy savings identified
Challenge
The brief
Compressed air is among the most expensive utilities in a plant, and generation efficiency, distribution pressure and leakage needed to be established by measurement rather than assumption.
Assessment
What we did
A compressed air system performance assessment was carried out as per BEE guideline practice, covering free air delivery, specific power consumption, pressure profile, intercooler and aftercooler performance and leakage quantification.
Findings
What the data showed
- Deviation between measured and rated specific power consumption
- Elevated inter-stage air temperatures indicating cooling performance loss
- Quantified leakage load identified and tagged for correction
Recommendations
What we recommended
- Correction of tagged leaks with re-measurement
- Cooling circuit performance restoration
- Compressor loading and pressure setting optimisation
