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 heat input to the fractionation column is controlled in response to the temperature requirement signal, corrected as necessary by actual analysis of the product. In a preferred embodiment, control of a demethanizer column in a cryogenic natural gas liquids separation process can be practiced advantageously.
