located in Kuala Lumpur Malaysia
Waste has always posed an issue to the local governments and authorities, as waste increase so do costs
to deal with it. From landfill management to illegal dumpsites, and if waste is not treated properly it could
pose an even greater risk to the environment.
Waste-to-Energy installations can help reduce this risk, by reducing CO2 emissions and possibly replacing
fossil fuels.

INDUSTRY’S CHOICE IN WtE APPLICATIONS

INITIAL SYSTEM DESIGN
Based on our client’s requirement and approvals from the relevant local authorities for a Feed-In-Tariff
generation of 2 Megawatts we set out to determine the best possible solution for the overall plant design.
The Landfill gas is extracted from the landfill through pipes laid and the installation of blowers to provide
the pressure required for the gas to be fed into the Gas Generator.
Flow charts are produced to show the
specific requirement and information
that will be present at the site, these
includes all the pressure drops and
flows as our engineers would have to
size the pipes and lengths accordingly.
All drawings are customer approved and
produced internally by experienced draftsman via
AutoCad.

PLANT EQUIPMENT
For a Waste to Energy plant to operate efficiently the main requirement is that the fuel is of the best
quality, since the gas that is being extracted from the landfill contains impurities that may harm the gas
engine a pre-treatment system has to be designed and installed before the gas engine. For this job, we
went with a chiller and an activated carbon scrubber to remove the H2S as well as Siloxane contents in
the landfill gas.
Installation of Chiller, Scrubber & Engine Radiator
Remote Radiator Installation – Both the HT & LT lines of the engine
have been combined into a single radiator whereby 10 fans start on
demand to achieve efficient cooling and maintaining a suitable
temperature for optimum engine operation
The Chiller & Activated Carbon Scrubber is installed to remove any
impurities in the Landfill Gas, this is our pre-treatment system for the
landfill gas before it enters the engine, this system has been
carefully designed and calculated so that the flow and temperature
should not have a variation of more than 10 -15 degrees when it
reaches the engine
Installation of Gas Pipes, Radiator HT & LT Lines as well as Cables
Trays

Pressure drop calculations as well as simple simulations were performed by our designers, with these
figures in hand the confirmation that the gas would reach the engine’s gas train with enough flow and
pressure is performed. The gas engine’s gas train includes all the necessary methane analyzers, flow
meters as well as all required pressure regulators and flame arrestors for a safe and proper operation.
Gas Generator gas train (In Yellow) with all the other auxiliary equipment including ventilation & exhaust fans as
well as the cooling pump skid
Cables from all the equipment as well as the generator set are marshalled back into the control room
where by we have installed the engine management unit and the auxiliary power panel

The output of this alternator is at 11kV and syncs to the main grid at 33kV through a series of protection
breakers as well as a step-up transformer, all these were designed and installed check and tested to the
relevant local authority standard.
With this completed, we are now awaiting Sustainable Energy and Development Authorities (SEDA)
reliability run which requires a continuous 14 days running period so as to prove that the installation can
deliver the power reliability to the national grid.
Auxiliary Panel installation – Panel is
used to power all equipment
Proper Cable trenches and cable
trays are neatly positions and cable
laid
Cable trays are laid too all
equipment, together with cable
neatly terminated
