Abstract
The present invention is related to an advanced control method—including a fast response method—to stabilize, optimize and or maximize the output flow of an evaporation unit via ultrasonic controlled sound or vibration applied to the said evaporation unit. The invention further provides equipment wherein said method is being implemented, such as an evaporation or separation unit.
Claims14
A method of controlling physical properties of a liquid fraction and/or a vapour fraction of an output stream of an evaporation unit, the method comprising:
- providing setpoint values for the physical properties of the liquid fraction of the output stream and/or of the vapor fraction of the output stream of the evaporation unit;
- measuring one or more of the physical properties of the liquid fraction of the output stream and/or one or more of the physical properties of the vapor fraction of the output stream of the evaporation unit;
- comparing the provided setpoint values with the measured values of the physical properties of the liquid fraction of the output stream and/or of the physical properties of the vapor fraction of the output stream of the evaporation unit;
- and
- adjusting the physical properties of the liquid fraction of the output stream and/or the physical properties of the vapor fraction of the output stream of the evaporation unit to match the setpoint values by adjusting an energy input of the vaporization input, wherein the energy input is a combination of a heat input stream and an ultrasound input, and wherein adjusting the energy input comprises keeping the heat input stream level and adjusting the ultrasound input, and wherein a control algorithm for adjusting the physical properties accounts for a fast response time of the adjusting of the ultrasound input and for dead time of pressure measurement devices within the evaporation unit.
