Energy Optimisation

Energy is a core resource for MSM’s operations. MSM Johor,
MSM Prai (and where applicable in SBW) rely on diesel, natural
gas, purchased electricity and steam as energy sources.
In addition, MSM Johor and MSM Prai also generate their
own electricity via the steam turbine generator as part of
MSM’s commitment under its Group Sustainability and
Environmental Policies to reduce impact of fossil-fuel based
energy and improve energy efficiency.

The back-pressure turbines installed in our refineries generate
approximately half of our energy requirements, in particular
in MSM Johor, by channeling exhaust steam back to the
heating process. We also recycle our process condensate
for boiler steam generation and employ an innovative system
