Development of an algorithm for correction of specific gravity of biodiesel

This communication reports the development of an algorithm for correction of specific gravity of biodiesels. The specific gravity of cottonseed oil biodiesels (for example) was measured at different temperatures and the algorithm was proposed for correction of this parameter depending on temperature, which highly influences loading and discharging of biodiesel. The obtained algorithm differs from that reported in EN 14214 and suggests that individual algorithms should be obtained for biodiesels produced from different oil sources.
