NYK Group develops lubricity-improvement additive

Tokyo-based NYK and its subsidiary Nippon Yuka Kogyo have jointly developed an additive (Yunic 700LS) for low-sulfur marine gas oil. Blending Yunic 700LS into low-sulfur, low-lubricity marine gas oils could improve lubricity by about 30%, using the High Frequency Reciprocating Rig (HFRR) test, as well as actual machine tests conducted by fuel-pump makers. By blending this additive into low-sulfur marine gas oils, mechanical troubles in fuel-oil systems, which can result from the use of low-sulfur marine gas oils, can be prevented, the company said.
