METHOD FOR ADJUSTING THE OPERATING POINT OF A PRESSURE WAVE GENERATOR FOR TREATING A LIQUID
A method for adjusting the operating point of a pressure wave generator for treating a first liquid, in particular a mineral oil, with pressure waves of a first frequency for increasing the portion of low-boiling fractions in the liquid. The pressure wave generator is communicated with a second liquid, in particular water, via flowed-through pipe(s) (piping(s) and the frequency of application via the pressure wave generator is varied. An operating point is determined as a maximum in temperature rise of the second liquid, after passing the pressure wave generator, as a function of the frequency of application.
