Petrochem giant achieves sustainability goals through new water technology

news item image
The largest integrated petrochemical company in Indonesia has boosted sustainability through technology that enables effective remote and digital monitoring of its water operations.
Chandri Asri has incorporated Nalco Water’s 3D TRASAR Cooling Water Technology and has gradually moved more of its water monitoring to the programme.
Last year, the company reported its largest ever savings in water, energy, greenhouse gas emissions and waste.
Chandra Asri’s Cilegon plant achieved annual savings of 348 million litres of water; 6 million kWh of energy; 470,000 m3 of wastewater and 2,100 metric tonnes of CO2.
Allan Yong, Ecolab senior vice president and market head, Southeast Asia, hopes the progress made by Chandra Asri will inspire other companies to look at how they can use water more efficiently.
“The population growth and speed of development in Asia requires businesses to carefully manage resources with a focus on resilience and responsible operations,” said Yong. “Ecolab is committed to helping companies like Chandra Asri achieve their operational efficiency and sustainability goals. Harnessing 3D TRASAR for water management will help reduce costs and improve efficiency and sustainability.”
At Chandra Asri’s Cilegon plant, five 3D TRASAR systems are fitted to the facility’s cooling towers and dilution steam generation system to manage water quality to desired standards.
In cooling towers, the technology continuously ensures proper cycle concentration, achieving the best use of water.
When used in boilers and heat exchangers, 3D TRASAR technologies can reduce the potential of corrosion and deposit buildup and help maintain high energy efficiency and asset integrity.
Erwin Ciputra, president director and CEO at Chandra Asri, added: “We are pleased to continue growing our partnership with Ecolab, to implement state-of-the-art and market leading technological advancements to improve the sustainability and performance of our operations. Prior to installing 3D TRASAR our engineers were conducting regular tests manually by taking water samples and having them analysed.
“Now we can do all that measurement remotely, and our engineers can get automatic alerts if changes in the water system exceed or fall below predetermined limits.”
