Diesel B5 S-50, also known as Diesel Ultra, has gained widespread acceptance within the mining industry because of its lowered sulfur content, high cetane content, and optimum lubricity, underscored Rafael Chihuan Pariona, supervisor of technical services at Petroperú.
At Rumbo a PERUMIN – Central Peru Edition, he explained that this fuel, which is 95% diesel and 5% biodiesel, contains high doses of additives that maintain engine power and take better advantage of the amount of energy in the fuel.
“With one of the latest generation additive packages, our Diesel Ultra improves performance and extends the useful life of mining engines, protects them against corrosion, lowers emissions, and reduces maintenance expenses,” remarked the specialist.
According to the representative, diesel B5 S-50 meets the technical specifications regulated by Supreme Decree 092-2009-EM, as amended, to be produced and distributed in gas stations affiliated to Petroperú.
Still, to introduce it into the mining sector, we need to consider particulate testing, whose maximum specification is 18/16/13 and whose reporting standard is ISO 4406, as required by manufacturers of engines found in the equipment most often used in mining.
“To meet this requirement, the product goes through a high-efficiency filtration process in our Mollendo and Eten terminals, and at Conchán sales plant. Once its production process is complete, the product is transported in fuel tankers with internal lining,” he detailed.
Diesel B5 S-50 processed by Petroperú is delivered at the Antapaccay and Cerro Verde mining operations, using a fuel pump or in fuel tankers. Finally, tests are conducted on samples on a weekly basis to ensure that the maximum specification of 18/16/13 is met.
To preserve the quality of Diesel Ultra, Rafael Chihuan recommended that clients implement a regular program to check the product’s appearance and conduct tests for water presence in the storage tanks at fuel storage facilities.
He also highlighted the need to implement a regular storage tank draining/cleansing program, a process which must be carried out after the product has rested. If you have three tanks or more, make a schedule, assign one reception tank, one rest tank, and one dispatch tank, and determine the optimal resting time for the product.
Finally, he suggested installing pressure/vacuum relief valves or desiccant respirator filters in the storage tanks, establishing a fuel discharge and manipulation protocol, and doing fuel quality control when fuel has been in storage for extended periods of time.
