Improve your landfill and biogas operations with the right lubrication 

The global energy market is experiencing a period of sustained growth; a demand that is increasingly being met by the use of alternative energy sources such as biogas, which is gaining traction due, in part, to its renewable nature.

However, landfill and biogases often include high levels of hydrogen sulphide, which can significantly limit the oil drain intervals of gas engine lubricants, and siloxanes, which can considerably increase wear and reduce engine life.

In addition, the arable sources of biogas can create specific challenges. The chemical agents used to protect crops can result in the presence of nitrous oxide, which can require an increased feed rate to maintain output.  This, in turn, places greater stresses on engine components and could lead to cracked pistons.

Optimising performance through lubrication

Fortunately, the use of high performance lubricants can help protect gas engine components against gas-related corrosion, helping to improve efficiency and protect productivity.

Mobil Pegasus™ 610 Ultra is specifically developed to withstand the effects of these aggressive gases by neutralising acids and offsetting their adverse effects on engine components (cylinder liner and piston rings).  Combined with excellent oxidation stability, the oil helps extend oil drain intervals, reduce unscheduled maintenance costs and increase overall engine operations.

The ability to manage varying gas qualities and increased engine outputs – while maintaining reliability – will remain a challenge.  Operators will therefore need to ensure that the lubricants they choose can neutralise the potential threats these gases can pose to engine operation.  Fortunately, advances in lubricant formulation can help ensure reliable operations.
