METHOD FOR ADJUSTING THE OPERATING POINT OF A PRESSURE WAVE GENERATOR FOR TREATING A LIQUID

摘要

A method is disclosed for adjusting the operating point of a pressure wave generator for treating a liquid, in particular a mineral oil with pressure waves of a first frequency for increasing the portion of low-boiling fractions in the liquid characterized in that the pressure wave generator is communicated with a liquid, in particular water, via flowed-through pipings and the frequency of application is varied and the operating point is determined as a maximum in temperature rise of the liquid after passing the pressure wave generator as a function of the frequency of application.
