Leveraging Energy Efficiency Opportunities Lead To Big Savings For Businesses

05 Oct 2017

Highest number of Energy Efficiency National Partnership Awards given out for delivering tangible energy savings

Singapore, 5 October 2017 – For their efforts in being environmentally sustainable, 12 companies, two energy services providers, one certified energy manager, two public sector agencies, and two schools received the Energy Efficiency National Partnership (EENP) Awards 2017, making it the largest number bagged since the Awards started in 2011 (refer to Annex A for details on the EENP Awards).

2          The winners received the EENP Awards from Guest-of-Honour Mr Masagos Zulkifli, Minister for the Environment and Water Resources, at the Awards ceremony held during the National Energy Efficiency Conference (NEEC) on 5 October 2017. Now in its seventh year, the EENP Awards is jointly organised by the National Environment Agency (NEA), the Economic Development Board (EDB) and the Energy Market Authority (EMA).

3          This year, a new award category, “Outstanding Energy Services Providers of the Year” (OESP) was added to the annual EENP Awards to recognise energy services providers as an important part of the energy efficiency ecosystem. This move is aligned with the efforts to build a diverse ecosystem of energy services providers in Singapore. The existing three categories of the EENP Awards are: (i) “Excellence in Energy Management” (EEM), (ii) “Best Practices” (BP) and (iii) “Outstanding Energy Manager of the Year” (OEM). Deserving public agencies were also recognised at the ceremony and commended with the “Best Energy Efficiency Practices in the Public Sector”.

4          One of the recipients under the “Outstanding Energy Services Providers of the Year” (OESP) category was Actsys Process Consultants Pte Ltd. Actsys was incorporated in 2001 and primarily serves the power and process sectors. Key to Actsys’ winning the award was their consistent track record with clients and their commitment in supporting them to achieve excellence in energy management and efficiency gains. For instance, Actsys spent two years assisting one of their clients to make sure their data measurement instrumentation was accurate, so that simulation models that were built ran on accurate measured data. In addition, Actsys made significant contributions to energy efficiency capability building efforts in Singapore, through training local engineers and sharing its experience in improving the energy efficiency of industrial processes and energy-consuming systems at conferences and workshops.           

5          The five recipients of the EENP Awards under the Excellence in Energy Management (EEM) category are companies from diverse industry sectors such as refining, petrochemicals, precision engineering, electronics and power generation.

6          One of the award recipients, Ardentec Singapore Pte Ltd, a small and medium sized enterprise (SME), provides testing services to semiconductor companies in Singapore. Ardentec has a dedicated Task Force Team to drive energy efficiency projects. With the support and commitment of top management, Ardentec has set a target of 3 per cent year-on-year improvement in energy efficiency. Between 2012 and 2016, Ardentec realised annual savings of about 349 megawatt hours (MWh) of energy or approximately $70,000.

7          Another winner in the EEM category, Shimano (Singapore) Pte Ltd, demonstrated how the continual improvement framework provided by an energy management system such as ISO 50001 is a powerful enabler for sustained energy efficiency as it incorporates energy management into everyday organisational practices. Shimano (Singapore) has a top management-led Energy Management System (EnMS) committee, which includes representation from every department. The EnMS committee makes sure that energy considerations are taken into account in organisational decisions, and plan energy-related training for staff at all levels. Between 2013 and 2016, Shimano Singapore reduced its annual energy consumption by 38 terajoules (TJ), and is now targeting to improve energy efficiency by 5 per cent yearly from 2016 to 2020.  Shimano Singapore’s success benefits the entire Shimano family as it also assists Shimano’s regional factories to improve their energy management systems. 

8          The Best Practices (BP) award recipients motivate others with their innovative energy efficiency improvement projects. Collectively, the projects associated with the two award recipients and six others with Honourable Mentions account for annual energy savings of about 1290 TJ, equivalent to removing 74 kilotonnes of carbon dioxide[1] from the atmosphere or removing about 22,630 cars from the road[2]. This year’s award recipients are Shell Chemicals Seraya Pte Ltd (Jurong Island) and ExxonMobil Asia Pacific Pte Ltd (Singapore Refinery). What the two companies have in common are dedicated energy management teams to monitor and track energy usage. They also engage employees across the company to find ways to improve energy efficiency.

9          Shell Chemicals Seraya’s award-winning project showed how existing processes could be redesigned to be more energy efficient – a new flash vessel was added upstream of an existing one to create an additional flash stage for the hot reactor effluent stream and to provide the heat required to further vaporise the hot reactor effluent stream to achieve the desired concentration. This replaces the need for low pressure steam in the existing flash vessel and reduces energy consumption. Along with other energy reduction initiatives, Shell has reduced its overall steam consumption by about 15 per cent.

10        ExxonMobil Asia Pacific Pte Ltd (Singapore Refinery)’s investments in energy saving technology paid off in a major way, winning them three awards this year. ExxonMobil manages its energy use through the application of Real Time Optimisation (RTO) at its Singapore Refinery. An RTO application was developed in-house with rigorous models of the process units and equipment within the continuous catalytic reformer (CCR) complex to optimize real time process operating conditions. As a result, ExxonMobil was able to challenge conventional operating principles and reduce energy use by the reboilers in the CCR complex in a cost-effective manner, while maintaining safety and reliability. The project led to an annual energy savings of 33 GWh and clinched the company an EENP Award (BP category). ExxonMobil also won an EENP Award (EEM category) for applying its Global Energy Management System (GEMS) to manage energy use. GEMS employs a layered, progressive approach to ensure that critical aspects of plant operations and equipment are covered, while engaging key players and stakeholders throughout the organisation. From 2002 to 2016, the energy intensity at ExxonMobil improved by 25 per cent, or about 1.7 per cent a year over 15 years.

11        While energy efficiency hinges on a sound energy management system and a good grasp of best practices, individuals play an indispensable role in driving energy efficiency initiatives. This year, the “Outstanding Energy Manager of the Year” award was awarded to Mr Avtar Singh, Energy Manager at MSD International GmbH (Singapore Branch). Going beyond his routine duties, he strives for continual improvement, improving the organization’s documentation of energy savings, as well as the suite of energy efficiency outreach and advocacy programmes within MSD. Mr Singh also actively shares best practices with other pharmaceutical manufacturing companies through the Biopharmaceutical Manufacturers’ Advisory Council (BMAC).

12        The Ministry of Finance (MOF) received a commendation for its commitment to reducing the carbon footprint at the Treasury Building. MOF is the first ministry to adopt the Guaranteed Energy Savings Performance (GESP) contracting model for its chilled water plant retrofit back in 2010. Under this contracting model, the contractor designed, implemented and guarantees the energy performance of the system retrofit. If the performance falls short of the guarantee, the contractor pays MOF the shortfall in savings. To date, MOF has implemented two GESP projects and many other energy saving measures, which have led to a 35 per cent reduction in the Treasury Building’s electricity consumption, compared to their 2002 baseline.

13        Key to this year’s winners’ success was the commitment of top management to continually identify opportunities for energy efficiency improvement through a series of self-assessments. These include actively engaging process owners, conducting energy audits and tracking their energy improvement initiatives on a regular basis. These are in fact the key elements of an energy management system.

14        “The companies and individuals recognised at the Energy Efficiency National Partnership (EENP) Awards 2017 are leading the charge in the fight against climate change. Their exemplary efforts show that improving energy efficiency is not just beneficial to the environment, but also to their company’s competitiveness through lower operating costs.  NEA encourages businesses to adopt more efficient practices to help transform Singapore into a leading green economy as envisioned in the Sustainable Singapore Blueprint,” said Mr Ronnie Tay, Chief Executive Officer of NEA.

15        The EENP Awards ceremony was the culmination of the National Energy Efficiency Conference (NEEC) themed “Building an Energy Efficiency Ecosystem”, a two-day event for industry experts to share energy management strategies. The NEEC is organised biennially by NEA, EDB and EMA, and provides a platform for high-level dialogue and thought leadership around Singapore’s use of energy for greater energy competitiveness and energy resilience. This year’s conference focuses on the importance of mutually beneficial relationships among stakeholders in the energy efficiency ecosystem, an idea reinforced by the sharing of practices at presentations by award winners and industry energy professionals during the conference. There are also exhibitions featuring the latest technical innovations and other solutions to improve energy efficiency.

2.    Award Category: Best Practices

This recognises corporate teams that have implemented energy efficiency projects which have led to improvements in the energy performance of their facilities.

ExxonMobil Asia Pacific Pte Ltd – Singapore Refinery

Project title: Managing energy use through the application of Real Time Optimisation (RTO) at ExxonMobil Singapore Refinery

The project involved the development and use of Exxon’s Real Time Optimisation (RTO) technology to continuously enhance the trade-offs between energy utilisation and the degree of fractionation within the ExxonMobil Singapore Refinery’s continuous catalytic reformer (CCR) complex, while factoring in plant constraints and economic information. An RTO application was developed in-house with rigorous models of the process units and equipment within the CCR complex to optimise process operating conditions in real time; the models themselves were created using RTO modelling software that is available in the market.  As a result, ExxonMobil was able to challenge conventional operating principles and reduce energy use by the reboilers in the CCR complex in a cost-effective manner, while maintaining safety and reliability. The project led to an annual energy savings of 33 GWh.

Shell Chemicals Seraya Pte Ltd – Shell Jurong Island

Project title: Energy savings from two-stage flashing

Flash vessel V-204, which operates under vacuum conditions, is used to concentrate the hot reactor effluent stream. Prior to the project, additional heat had to be supplied, through a low pressure (LP) steam reboiler, to further vaporise the hot reactor effluent stream in V-204 to achieve the desired concentration.

In this project, Shell added a new flash vessel V-201 upstream of V-204 to create an additional flash stage for the hot reactor effluent stream. The additional heat input required to further vaporise the hot reactor effluent stream in V-204 is provided by the hot vapour from V-201 overhead through a heat exchanger, thus eliminating the need for LP steam.

Often, petrochemical plants are long on LP steam which makes initiatives to save LP steam unattractive as the steam saved will be vented anyway. Instead of venting the LP steam, Shell installed a small stripper column at the bottom of an existing distillation column to allow its medium pressure steam reboiler to use LP steam. The project, together with other minor energy reduction initiatives, saved more than 20 t/h of LP steam, reducing the overall steam consumption by about 15 per cent.

DCP (Sentosa) Pte Ltd., with Barghest Building Performance Pte Ltd (Honourable Mention)

Project title: Energy efficiency improvement through installation of plant optimizer at DCP

DCP, together with Barghest Building Performance (BBP), customized and installed the chiller optimizer solution, keeping in mind the critical operation of a district cooling plant. The system optimized the energy use for chillers, pumps and cooling tower fans using an algorithm-based dynamic control to achieve and maintain better plant efficiency across varying load profiles without affecting the comfort of occupants. The system also allowed for continuous improvements through remote monitoring, daily performance reports and data analytics that would lead to immediate corrective actions whenever necessary.

The successful implementation of the project resulted in a 10 per cent improvement in plant efficiency, or 5.5 GWh of annual energy savings without disruption to operation.

Eastman Chemical Singapore Pte Ltd, with Koch-Glitsch Asia Pacific (Honourable Mention)

Project title: Distribution system upgrade for hydrogenation reactor

Hydrogenation reactor internals such as inlet diffuser and liquid distribution tray are used to provide uniform distribution of liquid and vapour across the reactor bed. To improve the reactor performance, Eastman Chemical Singapore replaced the existing trough distributor and parting box with a new high-efficiency distribution system which comprised Eastman’s proprietary-design bucket-type pre-distributor as inlet diffuser and Koch-Glitsch deck-type distributor as top distribution tray. This new unique design provided a more uniform distribution across the reactor bed, thereby resulting in higher product conversion and less by-product formation. Therefore, less steam was required at the downstream product purification system to treat the by-product. This successful project led to an annual energy savings of 29 TJ and a system level energy efficiency improvement of 11 per cent.

Fuji Oil Singapore Pte. Ltd (Honourable Mention)

Project Title: Replacement of existing vacuum system with ice condensation vacuum system at Fuji Oil refinery plant 

Deodorization is a process to remove unwanted Free Fatty Acids (FFA) from edible oils. Steam is introduced in the deodorizer columns to strip the FFA from the edible oils. The FFA and stripping steam are then removed from the columns using a vacuum system. The conventional vacuum system which comprised several large and small steam ejectors, consumed a large amount of steam. To reduce steam consumption, Fuji Oil Singapore replaced the conventional system with an ice condensation vacuum system. This new system comprises an ammonia compressor and small steam ejectors. The increase in electricity consumption of the new system was more than offset by the large decrease in steam consumption, leading to an overall reduction in energy consumption. This project resulted in an annual energy savings of 16 GWh and a system level improvement of 74 per cent.

Nestlé Singapore Pte Ltd (Honourable Mention)

Project title: Waste heat recovery from boiler flue gas by installing condensing economiser for Loos boiler

15t/h of steam was produced from Nestlé’s natural gas fired boiler which had a design feed water proportion of 20 per cent condensate return and 80 per cent make-up water from softener. Prior to project implementation, make-up soft water was supplied to the deaerator at 31°C and further heated in the deaerator using steam while boiler flue gas was discharged to the atmosphere at about 120°C.

To improve energy efficiency, Nestlé installed a condensing economizer to recover both sensible and latent heat from the flue gas to preheat the make-up soft water before it entered the deaerator. The soft water supply temperature increased from 31°C to 60°C, thereby reducing the amount of steam required to heat the soft water in the deaerator. Flue gas temperature was discharged to the atmosphere at about 75°C. The annual deaerator steam consumption decreased from 9,571 to 5,716 tons. This translated to energy savings of 40 per cent at system level and 4 per cent at facility level.

Petrochemical Corporation of Singapore (Private) Ltd (Honourable Mention)

Project title: Improve thermal efficiency of fired process cracking furnaces

PCS adopted a holistic approach by implementing the following measures to improve the performance of its cracking furnace in PCS I plant.

1)    Installed additional pre-heating coils to increase the heat transfer area to recover heat from flue gas within physical and structural limits.

2)    Switched from existing air lance cleaning to dry ice blasting to improve cleaning of closely packed heating coils in the furnace convection section and provided more openings for effective cleaning.

3)    Installed matched certified thermocouples (MCTC) to minimise deviation between the outlet temperatures of the heating coils in the furnace radiant section, thereby improving yield of desired product. MCTC are manufactured and calibrated in the same batch to minimise temperature measurement discrepancies.

The modifications reduced heat loss and improved furnace efficiency, thereby resulting in an annual energy savings of 84 TJ.
