Energy Management
Tank Insulation Dumai, Insulation to reduce energy required to keep the 108 tanks
Indonesia tanks at the optimal temperature insulated
Increase • Balikpapan, Increase in use of palm kernel shell, wood bark, 6.65% of energy
renewable Indonesia straw, rice chaff and biodiesel source is from
energy sources • Dumai, palm kernel
Indonesia shell, wood
• Marunda, bark, rice chaff
Indonesia and biodiesel
• Tanjung Balai,
Indonesia
Replace Heat Nanjing, China A new heat exchanger in the refining workshop cut Expected
3
Exchanger steam use by 7 kg/t and is estimated to save 0.2 m to save
of natural gas per tonne of oil processed, boosting approximately
3
overall efficiency 116, 200 m of
natural gas
Water Management
Water Huelva, Spain Installed a system to recover a steam condensate line Reduction
Management from 293E1 (reboiler of Methanol Distillation Column) in steam
to feed 291E1 (Reaction Heat Exchanger) consumption by
250 kg/h steam
consumption
i.e.involves
a reduction
of 6-8% of
the initial
consumption
Marunda, Conducting feasibility study of minimising steam lost Feasibility
Indonesia and recovery steam condensate, leading to reduction study has been
of water consumption and energy conservation completed
and work is in
progress
Padang, Reduce water consumption with Rain water Approximately
3
Indonesia harvesting system at Refinery 698 m of
rainwater have
been harvested
in Q4 2023
Marunda, WWTP recycling and RO water as boiler feed water In progress.
Indonesia To be completed
in 2024
