ExxonMobil oil saves mine operator fuel, CO2 emissions, and $1.1m
ExxonMobil’s premium hydraulic oil, Mobil DTE 10 Excel 46, has helped a mining company save over $1.1 million dollars.
The lubricant enabled the performance of two 250t capacity Terex excavators to become more efficient, safer, and use far less fuel. The operator previously used a more conventional hydraulic oil on two O&K RH 340 excavators, but experienced frequent failures due to cavitation damage and effects caused by seasonal temperature changes. This meant the business replacing 52 hydraulic pumps over 40 months, costing $54,000 each.
ExxonMobil was able to identify the issue and implement a solution in the form of its DTE 10 Excel 46 premium hydraulic oil. It boasts high viscosity and strong shear stability, enabling it to handle a wide range of temperatures and optimise machinery operations.
The mine operator reported that this solution helped eliminate oil-related hydraulic pump failure, improving productivity and enhancing safety due to a reduction in human-machine interaction of 160 hours. Fuel consumption was also reduced by 21,450 gallons, lowering CO2 emissions by 216 metric tons. All of this led to an estimated annual saving of $1.1 million.
“This is a great example of how a relatively small investment in a high performance lubricant can deliver significant productivity and financial gains,” said Mohamed Mourad, Industrial Marketing Advisor at ExxonMobil. “It’s also important to recognise the safety benefits – a top priority for all mine site operators. We’re delighted that our field engineers could help our customer optimise the performance of their machinery and improve their bottom line.”
Trafigura and Yara International explore clean ammonia usage
Reducing shipping emissions is a vital component of the fight against global climate change, yet Greenhouse Gas emissions from the global maritime sector are increasing - and at odds with the IMO's strategy to cut absolute emissions by at least 50% by 2050.
How more than 70,000 ships can decrease their reliance on carbon-based sources is one of transport's most pressing decarbonisation challenges.
Yara and Trafigura intend to collaborate on initiatives that will establish themselves in the clean ammonia value chain. Under the MoU announced today, Trafigura and Yara intend to work together in the following areas:
- The supply of clean ammonia by Yara to Trafigura Group companies
- Exploration of joint R&D initiatives for clean ammonia application as a marine fuel
- Development of new clean ammonia assets including marine fuel infrastructure and market opportunities
Magnus Krogh Ankarstrand, President of Yara Clean Ammonia, said the agreement is a good example of cross-industry collaboration to develop and promote zero-emission fuel in the form of clean ammonia for the shipping industry. "Building clean ammonia value chains is critical to facilitate the transition to zero emission fuels by enabling the hydrogen economy – not least within trade and distribution where both Yara and Trafigura have leading capabilities. Demand and supply of clean ammonia need to be developed in tandem," he said.
There is a growing consensus that hydrogen-based fuels will ultimately be the shipping fuels of the future, but clear and comprehensive regulation is essential, according to Jose Maria Larocca, Executive Director and Co-Head of Oil Trading for Trafigura.
Ammonia has a number of properties that require "further investigation," according to Wartsila. "It ignites and burns poorly compared to other fuels and is toxic and corrosive, making safe handling and storage important. Burning ammonia could also lead to higher NOx emissions unless controlled either by aftertreatment or by optimising the combustion process," it notes.
Trafigura has co-sponsored the R&D of MAN Energy Solutions’ ammonia-fuelled engine for maritime vessels, has performed in-depth studies of transport fuels with reduced greenhouse gas emissions, and has published a white paper on the need for a global carbon levy for shipping fuels to be introduced by International Maritime Organization.
Oslo-based Yara produces roughly 8.5 million tonnes of ammonia annually and employs a fleet of 11 ammonia carriers, including 5 fully owned ships, and owns 18 marine ammonia terminals with 580 kt of storage capacity – enabling it to produce and deliver ammonia across the globe.
It recently established a new clean ammonia unit to capture growth opportunities in emission-free fuel for shipping and power, carbon-free fertilizer and ammonia for industrial applications.
