Afton Chemical Asia awarded honourable mention for Best Practices in the Energy Efficiency National Partnership Awards 2021
The air compressor energy reduction project has been initiated as part of the company’s energy reduction projects aimed at improving energy efficiency and minimizing waste in the facility. Senior Production Engineer, Koh Kar Boon and Maintenance Supervisor, Kumar Varadharajan identified that the batch production nature of the facility with varying start / stop timing for three production units resulted in un-even utilization of compressed air during power handling.
The team studied the pattern of header pressure changes and air compressor performance to get a better understanding of the facility’s air consumption. Surge line modelling was used to calculate a varying throttle limit for the compressor and build in last stage pressure against surges. The compressor sequence was also adjusted to adapt the header pressure changes and coasting time. A key challenge is to maintain the stable air supply to the three different production units. Compressor capacity control tuning was done with the help of the OEM team. After the adjustments, only one compressor out of the three is required to keep the facility running. A second compressor starts only occasionally to maintain the header pressure when one compressor is unable to meet the demand.
“Our energy efficiency efforts have not only reaped cost savings, but it also means improved equipment reliability and increased equipment availability. Actual annual energy savings on a system level is 34.2% and 3.2% on a facility level with no CAPEX outlay,” says Kew Jin Woon, Plant Manager, Afton Chemical Asia.
Afton Chemical is a global specialty chemical additives company that is committed to delivering innovative fuels and lubricant additives that support a cleaner, sustainable future.

Energy efficiency is one of the key metrics that we are always striving to improve on for our equipment and systems. Besides the air compressor energy reduction project, we are concurrently working on hot oil heater operation optimization, process chiller running optimization, tank recirculation pump optimization etc,” added Jin Woon.
The EENP Awards is organized annually by the National Environment Agency, Energy Market Authority and the Singapore Economic Development Board since in 2011 to recognize EENP Partners for their efforts and achievements in improving energy efficiency. The EENP Awards aims to foster a culture of sustained energy efficiency improvement in the industry and encourage companies to adopt a proactive approach towards energy management.
