Abstract
A method for automated control of a petroleum distillation column in which signals representing temperatures, pressures and fluid flow rates for selected product streams withdrawn from the column are transmitted to a digital computer where, by means of a programmed algorithm, they are used to derive a true boiling point curve for the petroleum products of such product streams. The true boil point curve is then used to infer selected properties for the petroleum products which are compared with desired properties for the products of the monitored product streams and the differences between the inferred and desired properties are utilized to adjust automatically one or more of the operating parameters for the column so as to move the column's performance incrementally towards optimization.
