ExxonMobil Corp, headquartered in the US, wasformed in 1999, by the merger of Exxon and Mobil.It is the largest of the six oil supermajors. It is alsothe worlds largest company by revenue, and thelargest refiner in the world.

Mobil Industrial Lubricants (MIL), a division of ExxonMobilprovides lubricants for many industries, including the miningindustry; supplying the end users, such as mining companiesas well as OEMs. Its products include greases as well ashydraulic, gear and engine oils. Mr Umut Urkun, ExxonMobilIndustrial Marketing Advisor, Europe, Africa and MiddleEast, says the company is looking to supply solutions for thewhole lifetime of its lubricants, offering engineering services,increased productivity and safety.Industrial lubricants

ExxonMobils engineers work closely with leadingequipment manufacturers for insights into equipment

trends and lubrication requirements. These insights thenhelp guide product development, giving the researchchemists and lubricant formulators the ability to buildlubricants for some of the most demanding applicationsfrom the ground up. As part of ExxonMobil Fuels &Lubricants, the Mobil-branded industrial lubricants fieldengineering services (FES) team offers advice on soundlubrication practices.

Mobil SHC next-generation lubricantsWhile the primary function of a lubricant is to protect

equipment, reduce unscheduled downtime and extendoil drain intervals, advancements in synthetic lubricanttechnology now mean mining companies can selectoils and greases which provide outstanding levels ofprotection as well as other potential benefits such asimproved fuel economy.Three next- generation productshave recently been added to ExxonMobils Mobil SHCsynthetic lubricants family. Mobil SHC products helpdeliver overall balanced performance while offering newlevels of energy efficiency, sustainability and safety-related benefits. Key products include:

Mobil SHC 600 - the enhanced formulation has beenupgraded to improve viscosity and low-temperatureproperties while delivering outstanding performanceacross a wide range of circulating and gear applications,all with up to 3.6% energy efficiency. Energy efficiencyrelates solely to the fluid performance when comparedwith conventional reference oils of the same viscositygrade in gear applications. The technology used allowsup to 3.6% efficiency compared with the reference

when tested in circulating and gear applications undercontrolled conditions. Efficiency improvements varybased on operating conditions and applications.

Mobil SHC Gear - this gear oil was reengineeredto help deliver optimum equipment protection and oillife in gearboxes, even under extreme conditions, withenhanced resistance to micropitting and significantreduction in energy consumption.

Mobil SHC Gear OH this customised formulation formining off-highway vehicle (OHV) electric wheel motordrives helps deliver wear protection and performance insevere duty cycles and extreme climates.

Signum oil analysisToday, more companies are seeking to intensify

predictive maintenance practices increasingly dependingon oil analysis to ensure equipment reliability and reducecosts. ExxonMobils on line Signum oil analysis programis specifically tailored to monitor critical indicators inused oil based on leading equipment manufacturersspecifications and international standards, resulting in a

Mobil branded industrial greasesMobil-branded industrial greases, whether mineral or

synthetic, help to protect equipment, extend re-lubricationintervals and help enable problem-free operation. Basedon carefully selected mineral and scientifically engineeredsynthetic base fluids, in combination with patentedthickener technology and synergistic additive systems,Mobil-branded synthetic greases are specially designedto meet a wide variety of operating conditions in bothindustrial and mobile equipment. These conditions includevery high and low temperatures, water contamination,heavy or shock loads, and variable speeds. Mobil-brandedsynthetic greases such as the Mobilgrease XHP MineSeries are available in a range of viscosity grades.

An operator in Egypt recently benefited fromintroducing the Mobilgrease XHP 322 MINE product intoits earthmoving equipment. The operator had previouslyused a lithium complex grease, however, this was leadingto high grease consumption, alongside frequent equipmentdowntime which was resulting in high labour costs tomaintain the machines. Following recommendationsfrom an ExxonMobil Field Engineer, Mobilgrease XHP322 MINE replaced a lithium complex grease in all 27 of

its earthmoving machines, due to the greases proventrack record to operate effectively in high vibration, hightemperature conditions.

The introduction of Mobilgrease XHP 322 MINE intothe earth moving equipment saw an impressive extensionin the re-greasing intervals of machinery, extending theseon average from 18 hours to 50 hours. The customerreports this reduction in grease consumption resulted ina saving of US$35,700 per year. Furthermore, due to thereduced equipment downtime, the company reports it wasable to increase productivity by 1.7% and save a furtherUS$46,900 per annum in labour costs.Commercial Vehicle Lubricants

In addition to greases, for mobile equipment ExxonMobiloffer a range of lubricants that deliver the combination ofexcellent performance as well as fuel economy and energyefficiency potential that operators strive for.

For over 80 years the Mobil Delvac brand has beenused in heavy-duty specialized lubricants for commercialand utility vehicles. Its formula, designed in the companys

global research facility in Paulsboro, New Jersey, US.ExxonMobils engineers are aiming to extend engine life,while meeting the next level of stringent pollution controlrequirements all around the world.

Synthetic lubricants are taking a larger share ofthe market; the range of Mobil Delvac helps make newequipment more efficient. The Mobil Delvac family ofengine oils consists of four commercial lubricants: MobilDelvac 1, Mobil Delvac XHP, Mobil Delvac MX and MobilDelvac Super 1400. While the ability of Mobil Delvac tohelp extend engine life has been proven, the companyalso seeks to extend the life of other components in heavy-duty equipment, by expanding the Delvac brand to includedrivetrain lubricants, greases, and coolants.

The heavy-duty diesel engine oil, Mobil Delvac 1 ESP5W-40 is another product engineered to deliver productivityand fuel economy benefits to mining customers. At theLa Herradura mine, located in Sonora Desert of Mexico,Construplan operates more than 40 pieces of heavy-dutyequipment, including large trucks, heavy-duty pickups andexcavators that rely on Mobil Delvac 1 synthetic heavy-dutydiesel engine oil. Along with heavy loads, the equipment atthe mine is often subjected to extreme conditions - rangingfrom 50 degrees Celsius (125 F) in the summer to -10 Cin the winter (-14F).

Since implementing Mobil Delvac 1 in its operations,Construplan has reported significant benefits, including

enhanced equipment performance, increased uptime,improved fuel economy and extended oil drain intervals.

As a result, Construplan leaders say they have been ableto reduce oil consumption, minimise used oil waste, andmaximise the overall productivity of their equipment andpeople.

The benets of high performance synthetic oilsin mining applications

ExxonMobil believe that by combining the use of highquality synthetic lubricants and an effective oil and equipmentanalysis programme, mining operators can look to achieve acompetitive advantage in their operations, helping to maximiseproductivity and reduce the fuel consumption potential of theirmining machinery and equipment. In addition, health andsafety benefits may also be realised. By reducing scheduledand unscheduled maintenance, operators can eliminatethe associated safety risks that engineers face whenundertaking work.
