ExxonMobil oil offering set to benefit CHP engines

ExxonMobil unveiled the latest addition to its gas engine oil portfolio at POWER-GEN Europe at the end of June. Matti Alemayehu and Emre Noyan from Exxon spoke to Decentralized Energy about what the product can do for combined heat and power engines.

The company chose the Cologne event to launch its next generation series of gas engine oils to keep up with the latest gas engine developments. The Mobil Pegasusà¢â€ž¢ 1100 Series has been inspired by major OEMs to cope with severe engine conditions and significantly extend oil drain intervals.

Matti Alemayehu, Senior Researcher on the project said the company is excited about the gains associated with the producMatti: “Our team formulates the lubricants for natural clean gas engines as well as landfill and biogas so this week we are here to launch this product and it was developed to facilitate ffiancing of customers that use natural as engines that are high BMP engines, naturally aspirated or turbo charges.”

That durational advantage is of particular interest to CHP operators who must comply with an ever increasing regulatory pressure to reduce emissions. Perfecting the substance and bringing it to market has taken time.

“This oil has demonstrated a long oil life, up to 1.5 times longer than the leading competitors that are out there that are being used in these engines.”

“It does take some time to get out there, because once we develop the product from bench testing, it goes to engine testing and we also have to test it in OEM engines. It then takes 2-3 years to get all the approvals for us to be able to utilise the oil in these engine platforms.”

At the launch ExxonMobil had a joint presentation with Jenbacher, one of the key OEMs, demonstrating the collaboration on next generation oils and how they fit together.

Matti believes the Pegasus 1100 will appeal to the combined heat and power market for various reasons.

” CHP is expected to grow globally, so this product will facilitate efficiency for customers, it will coincide with maintenance interval, and help them comply with regulatory emissions issues they may be having because you have less lube oil consumption. It’s one of the main reasons this was developed because it gives them productivity and efficiency.”

“It’s runs for longer so in terms of oil drain interval, there is less oil handling, less emission and you can meet your regulatory compliance.”

Emre Noyan, Exxon’s EAME Industrial Marketing Manager chimes in to tell us that the Pegasus line is celebrating its 50th anniversary in 2017, before reinforcing the message on what the latest incarnation of the product can do.

“It extends the oil life and the customer has less down time and it improves your overall business practice. Typically, we are testing this ion a Jenbacher engine and typically the oil drain interval (ODI) for this is 1.5 time longer than the average industry-standard oil drain interval.”

“Typically the ODI in this engine is 1,300à‚  hours and has beenà‚  extended to 2.000 hours so that’s a big gain for the customer and also coincides with their maintenance interval which means a big saving.”

The testing undergone shows the lubricants exhibited excellent oxidation and thermal stability, which helps to extend oil life. The series’ anti-wear characteristics also help reduce wear of engine components and scuffing of liners in highly loaded gas engines.

à‚ In addition, the oil controls varnish formation and carbon deposits helping to maintain engine cleanliness.

“Gas engine development is pushing the boundaries of engine design to try and increase gas engine power and reduce costs.” said Inken Reuser, Industrial Marketing Advisor at ExxonMobil. “In turn, this has put higher demands on lubrication.

“This series is designed to keep up with recent gas engine improvements.”
