• Manganese least contaminant in PH standards

    0

    “Least of contaminants but a contaminant nonetheless.”

    This was how a product specialist on one of the biggest oil companies in the Philippines has described manganese on local fuels

    During a luncheon meeting, Jude Porras, specialist, Product Engineering of Chevron Philippines Inc. said that after saying that manganese is one of the allowed contaminants in the country.

    “But as part of the technical working committee of the DOE-PNS ( Department of Energy-Philippine National Standards), we are discussing it now,” Porras told the Times after the event.

    During the event, Porras said that has adverse effects on the life of the engine.

    According to him, using fuel with manganese additive cuts the life of spark plugs by 90 percent and could cause premature failing.

    He noted that as per DOE, they have been cleared of the said additive. “As far as chevron we dont use manganese and ferrocine as additives,” Porras said.

    Last October, an international company clarified that the presence of manganese on local fuels have no adverse effect on vehicles nor the environment.

    During a news forum, Afton Chemical Corporation marketing director John Walsh said that the MMT (methylcycloentadienyl manganese tricabonyl), a lead replacement additive, has already been in the country for more than a decade to help produce clean, environmentally beneficial, high octane gasoline that is compliant to the standards id Clean Air Act.

    Walsh cited that in December 2012, the US Agency for Toxic Substances and Disease Registry concluded that new manganese health science, including that developed by Afton, merited increasing the standard for the amount of manganese at can be safely inhaled.
    He said that the amount of MMT put in fuel is much lower compare to other additives such as lead based additives. He said that fuels are only blending 18 parts per million–equivalent to two drops every five liters of gasoline.

    He also cited that manganese–the 12th most abundant element and can also be found on soil and food–posed “no health hazard”based on US EPA standards.

    Further, Walsh backed the claimed with a study made by US EPA in 1994 that was reaffirmed in April 2013 resulted good news for the manganese-based additive. Based on its conclusion, mmt “will not cause or contribute to the failure of any emission control device or system.

    On the said forum, Independent Philippine Petroleum Companies Association (IPPCA) president Fer Martinez backed Walsh’s claims, saying that it is within the country’s health standards.

    “Members of the IPPCA which uses manganese additives to achieve a better octane rating assures that there is no health-related concerns that are being breached,” he told The Manila Times after the forum.

    “If its true (that manganese poses a threat), how come the Philippine standards allows it,” he added. RUBEN D. MANAHAN
