Abstract
In a fractionation system in which pressure fluctuations within the fractionation vessel can result in alteration of the fractionator product composition, fractionation column pressure is monitored and converted to a temperature requirement signal representative of the temperature required within a preselected portion of the fractionation column in order to provide the desired product constituent distribution. The temperature requirement signal is utilized to provide a required heat signal which is representative of the direction and magnitude of any change necessary in the heat input to the fractionation column to maintain the required temperature. The required heat signal is utilized to provide fast changes in the heat input to the fractionation column in response to pressure fluctuations in the fractionation column. The required heat signal is biased or trimmed by a comparison of the temperature requirement signal, corrected as necessary by actual analysis of the product, with the actual temperature in the fractionation column.
