Assessment of the Lubricity of Liquefied Gas with a DME-Fuel Additive Using a Multi-pressure/Temperature High-Frequency Reciprocating Rig (MPT-HFRR)
Transactions of the Japan Society of Mechanical Engineers. B, 2020Co-Authors: Kouseki Sugiyama, Masataka Kajiwara, Masahiro Fukumoto, Makihiko Mori, Shinichi Goto, Tomoko WatanabeAbstract:In this study, a MPT-HFRR (Multi-Pressure/Temperature High-Frequency Reciprocating Rig) was manufactured based on a diesel fuel Lubricity test apparatus. The MPT-HFRR was designed to be used for conventional test methods as well as for liquefied gas fuel tests. Lubricity tests performed on a calibration standard sample under both atmospheric pressure and high pressure produced essentially constant values, so it was determined that this apparatus could be used for assessing the Lubricity of fuel. Using this apparatus, the improvement of Lubricity due to the addition of a DME (Dimethyl Ether) fuel additive was investigated. It was found that when 50 ppm or more of a fatty acid Lubricity Improver was added, the wear scar diameter converged to 400 μm or less, and a value close to the measured result for Diesel fuel was obtained. The Lubricity obtained was considered to be generally satisfactory.

characterization of Lubricity Improver additive in diesel by gas chromatography mass spectrometry
Journal of Chromatography A, 2005Co-Authors: Michelle J C Rezende, Carlos Renato Perruso, Debora A Azevedo, Angelo C PintoAbstract:Abstract The characterization of Lubricity Improver additives by GC–MS–SIM is an important tool for the development and monitoring of new formulations as well as for quality control of additives in diesel. A simple method for the quantification of a linoleic oil additive derivative in diesel has been developed. Calibration is performed by analysis of standard solutions containing 2-hydroxy-ethyl linoleate with pentadecanoyl propanoate as the internal standard. The proposed method permitted the quantification of the linoleate ester at a concentration of 300 μg/mL in the additived diesel. The recovery of additive and the repeatability of the quantitative results are evaluated.
