The new contract follows 18 years of successful technical partnership, collaborating to help optimise UK landfill gas operations
• Mobil branded lubricants have helped Infinis increase oil drain intervals in specific landfill gas applications
• ExxonMobil and Infinis join forces to improve landfill gas operations
• Mobil branded industrial lubricants have a potential to help renewable power operators improve operational efficiency
ExxonMobil, a provider of advanced lubrication solutions for landfill gas (LFG) operations, signed a five-year contract with Infinis, an independent UK-based renewable power generator. The new contract follows 18 years of association with Infinis.
ExxonMobil will continue to supply three gas engine oils which have been specifically developed for use in LFG-generating operations, namely: Mobil Pegasus 605, Mobil Pegasus 610 and Mobil Pegasus SR. Mobil Pegasus SR was originally developed to address lubrication issues in gas engines operating at one of Infinis’ sites in the UK. ExxonMobil’s lubrication products are precision-formulated in accordance with the latest original equipment manufacturer (OEM) design trends, and have the potential to help LFG plant managers operate gas engines efficiently at full load capacity to boost productivity.
ExxonMobil and Infinis recently hosted a joint gas engine operations technical workshop at Infinis’ centre of excellence in Lancaster. Attended by ExxonMobil’s lead product developers and engineers as well as Infinis’ own technical experts, the workshop focused on collaborative new product development, mutual engineer training and best practice sharing. ExxonMobil continues to develop bespoke lubrication solutions designed to address the unique requirements of Infinis’ LFG operations – recently bringing to market a new engine oil for LFG applications designed in tandem with Infinis, Mobil Pegasus 605 Ultra.
Carsten Heck, Europe energy sector manager energy at ExxonMobil, commented: “The cornerstone of this long-standing technology partnership is the close link between our ExxonMobil Research and Engineering (EMRE) headquarters in Paulsboro and Infinis’ technology specialists. The EMRE experts in our laboratories for fuels and lubricants work closely with global gas engine original equipment manufacturers to ensure our advance performance products are formulated to meet industry requirements.”
Carsten added: “Our service team closely monitors the operational needs of Infinis to help maximise the production output of its landfill gas engines by extending oil drain intervals, extending the equipment life span and, therefore, helping to minimise costly repair and unscheduled downtime”.
Commenting on the new contract, Duane Longthorn, head of procurement at Infinis added: “We are pleased to continue our working relationship with ExxonMobil. Over the previous contracts we have achieved considerable production benefits and cost savings due to the extended oil drain intervals and equipment anti-wear protection, even under the most challenging operational conditions”.
Mobil Pegasus SR offers LFG operators control over piston wear and engine cleanliness, as well as reduced corrosion formation inside the engine liners1. The high performance series has undergone extensive bench and in-field testing, involving key OEMs, to help improve deposit control, achieve greater oil viscosity and to minimise wear. As a result, Infinis has been able to reduce the cost of equipment ownership .
1 A field evaluation of Mobil Pegasus SR was conducted in a Jenbacher J620 landfill gas engine at the Infinis Calvert site, during which it was compared to the engine manufacturers’ standard recommended lube oil product. During the field tests, Mobil Pegasus SR demonstrated a safe increase in oil drain intervals from around 400 hours to 1,500 hours, coincident with the increased servicing interval of other maintenance items on the engine. The endurance test also highlighted the oil’s ability to mitigate the detrimental effects of the fuel gas forming abrasive siloxane-related deposits and particles in the used oil and engine. This can be attributed to the detergent, dispersant and anti-wear additive system in this product. The tests also showed exceptional piston cleanliness, both in the piston grooves and the underside (especially noteworthy given the severity of this application).
