Abstract:
The invention concerns a method for determining the concentrations of chemical components of a product, in particular air, in a distillation column, said method involving implementing a model for estimating the concentration of the components from measurements carried out by one or a plurality of sensors, said model using an adjustment parameter making it possible to take into consideration operating variations of the column, the method also includes a step which involves detecting the values of said adjustment parameter that are outside a nominal variation range of said parameter in order to diagnose a fault D in one or a plurality of said sensors.
Abstract:
One of these distilling apparatus (10) comprises two columns, an evaporation column (14) and a condensation column (16), separated by a partition (18) equipped with rows of slits dividing them into 4 distillation stages. The evaporation column (14) comprises plates with hydrophilic or wettable faces, and the condensation column comprises rectangular hollow-plate (21) heat exchangers (221-6). Cold water ascends in these exchangers and saturated humid hot air descends in the condensation column (16). A perforated sheet (251-4) increases the uniformity of the partial airflows descending between the plates. The water is heated in a boiler (34); the hot water is scattered at the top of the evaporation column and the air cooled in the condensation column is sucked downwards by a fan (34). The air flows in a closed circuit. Performance is maximised, after the top temperature TE2 (45 to 90° C.) and the mass flow rate QE0 of the scattered water have been set, by adjusting the mass flow rate QA1 of the sucked dry air in order to give the temperature TA of this air a preset value at the top of the lowest evaporation chamber. Next, the effective cross sections of the partition apertures are adjusted in order to bring the air exiting from the evaporation chambers of higher rank to other preset temperatures TA2 to TAN, the enthalpy curves of the air deviating from flat by 6, with a satisfactory flow rate of distilled water. Applications: production of fresh or very high purity water; production of concentrated industrial wastewater; production of high-concentration ethanol, acids or bases.

Abstract:
A flood point for a packed column is determined by providing a data set of gas pressure drop values as a function of gas flow rate values at several liquid flow rates through a packed column, known flood point value for one liquid flow rate, setting flood point values for higher liquid flow rates at values lower than the known flood point value, and setting flood point values for lower liquid flow rates at values higher than the known flood point value, followed by expressing gas flow rates for liquid flow rates as fractions of the flood point value for each respective liquid flow rate. At a constant gas pressure drop, the method then includes calculating an average fractional flood point value for the liquid flow rates and minimizing the standard deviation between the fractional flood point value at different liquid flow rates and the calculated average fractional flood point value by iteratively resetting fractional flood point values and recalculating the average fractional flood point value for the liquid flow rates, thus resulting in determining a flood point for the packed column at any liquid flow rate, and thereby producing a plot of pressure drop as a function of fraction of flood point at any liquid flow rate, or a mathematical expression thereof that can be used in a computer-implemented column design and process modeling.
