Promoting industrial energy efficiency in Singapore

Narendra Agarwal writes on the Business Times website from Singapore about an important award won by Shell Chemicals Seraya for its activities to promote energy efficiency in its facilities. It is important to see the progress made in other countries.


Committed to a low-carbon future

FOR adopting energy-efficiency practices, Shell Chemicals Seraya (Pte) Ltd has won the EENP award for Best Practices for a project titled “Energy savings from two stage flashing”, which resulted in a 15 per cent reduction in steam consumption.

The Best Practices Award recognises corporate teams that have implemented energy-efficiency projects which have led to improvements in the energy performance of their facilities.

“We have implemented several projects that contributed to a lower energy footprint. These include the deployment of a two-stage flasher in which the reduction is achieved by heat integration and an expansion project in which we make more molecules with the same amount of energy.

Furthermore, we have an energy management system which enables us to operate in the most efficient possible way,” says Ong Lih Ren, process integrator, Second Stage Flash Project, Shell Chemicals Seraya (Pte) Ltd.

These initiatives have delivered business value through improvement in unit competitiveness, reduction of the site’s energy usage and CO2 footprint. “Ultimately, this results in a lower energy bill, but more importantly, these steps are contributing to the company’s commitment towards a low-carbon future,” he adds.

Improving energy efficiency will enable a sustainable way of producing chemicals which the world needs. Being efficient will also allow for the best use of limited resources.

“Being energy efficient will contribute to lower greenhouse gas emissions and energy cost, allowing us to operate more sustainably and responsibly. We realise that everyone in the organisation has a role to play to reduce energy consumption, from the leaders to those in the front line,” says Mr Ong.

“Hence, it is of utmost importance to advocate and embed the energy efficiency mindset at all levels in the organisation. Making use of IT tools to ensure efficient and optimal operation in combination with developing projects for the longer term to achieve structural energy savings in the process are also key,” he adds.

For promoting energy efficiency, Mr Ong says that having a steady operation is an essential first step.

“We are continuously striving to strengthen our energy journey and to keep improving our daily operations. In the long term, we need to ensure there is a healthy pipeline of economically viable projects which will further reduce the energy usage.”

On winning the Best Practices award, he says: “I am happy that our company is able to contribute to a sustainable future and I hope that others can draw inspiration to improve energy efficiency.”

Shell Eastern Petroleum (Pte) Ltd’s site at Jurong Island (SJI) manufactures petrochemicals for the region. SJI is integrated with Shell’s oil and petrochemicals site on Pulau Bukom. Together, the two sites form Shell’s largest oil and petrochemical manufacturing centre in the region.

Shell’s chemical manufacturing assets on Jurong Island manufacture ethylene oxide (which is converted into ethylene glycols and high purity ethylene oxide), ethoxylates, styrene monomer, propylene oxide and polyols. SJI’s mission is to ensure safe, reliable and responsive supply of these products to its customers.
