NYK and Nippon Yuka Kogyo Co., Ltd., an NYK Group company, have jointly developed a new fuel-oil additive effective in dispersing sludge* and reducing fuel consumption in VLSFO (very low sulfur fuel oil; sulfur content below 0.5%).
Background
NYK and Nippon Yuka Kogyo have been investigating the properties of VLSFO as one of the measures to comply with SOx emission requirements,** and in 2019 developed the sludge-dispersing fuel oil additive Yunic 800VLS.***
We observed Yunic 800VLS is effective against most of deteriorated compliant fuel oil, and with taking account into present fuel problem situations, we feel our main target need to be changed to reduction of fuel for contribution of environmental protection, from sludge trouble prevention.
Since we were aware of it, the both companies had been developing theYunic 800VLS “grade-up” version, which is having not only more powerful sludge dispersion characteristics to cover the rest of stubborn deterioration fuel, but fuel consumption reductions.
