PREPARATION METHOD OF ADDITIVE MIXTURES FOR MINERAL OIL AND MINERAL OIL DISTILLATES CAPABLE OF ENHANCING A HOMOGENEITY AND PRECIPITATION STABILITY OF THE MIXTURES

摘要

PURPOSE: A preparation method of additive mixtures for a mineral oil and mineral oil distillates is provided to enhance a homogeneity and precipitation stability of the mixtures and to produce additive mixtures of different components in a short time and a low cost. CONSTITUTION: The preparation method of the additive mixtures for a mineral oil and mineral oil distillates comprising a cold flowability enhancer(A) for middle distillates and at least one additional component selected from another cold flowability enhancer(B) and an organic solvent(C), comprises the step of mixing the enhancer and optionally the solvent using a static mixer. The temperature of the additive mixtures at an outlet of the static mixer is 0 to 100 deg.C.
