Novel Soft Sensor for Measuring and Controlling Product Recovery in a High-Purity, Multicomponent, Side-Draw Distillation Column

High Purity Distillation Column: Simulation and Optimization

Distillation columns with a high-purity product (down to 7 ppm) have been studied. A steady state model is developed using a commercial process simulator. The model is validated against industrial data. Based on the model, three major optimal operational changes are identified. These are, lowering the location of the feed & side draw streams, increasing the pressure at the top of the distillati...

ANN based soft sensor model for reactive distillation column

To cope up with the strict emission and product quality standards the process industries are stern for the maintenance of the product quality and waste emission. For process industries, online hardware analyzers are costly alternate for analyzing the product quality, they are switching to online soft sensors which are cheap and efficient in use. In this work, soft sensor based on artificial neu...

Minimum Energy Consumption in Multicomponent Distillation. 1. Vmin Diagram for a Two-Product Column

The Vmin diagram is introduced to effectively visualize how the minimum energy consumption is related to the feed-component distribution for all possible operating points in a two-product distillation column with a multicomponent feed. The classical Underwood equations are used to derive analytical expressions for the ideal case with constant relative volatility and constant molar flows. Howeve...
