Podobielniak Mini-cal High Temperature Distillation Apparatus Series 3400 Using Analytical-distillation

High-Temperature Simulated Distillation System Based on the 6890N GC

An Agilent Simulated Distillation (SimDis) system is described for characterizing petroleum fractions for quality control and monitoring of refinery feedstocks and products. The system uses a 6890N gas chromatograph (GC) equipped with a high temperature programmable temperature vaporizer (HT PTV) inlet designed specifically for simulated distillation analysis. A SimDis software program that cou...

Distillation Column Control Using the Whole Temperature Profile

Industrial distillation column control typically relies on one (or maybe two) carefully located tray temperature sensors. Here our aim is enhanced control by responding to movements in both the position and shape of the whole measured temperature profile. The control objective is to maintain end product specifications against feed composition disturbances using the measured temperatures and wit...

Optimal distillation using thermodynamic geometry

The thermal efficiency of a distillation column may be improved by permitting heat exchange on every tray rather than only in the reboiler and the condenser. Thermodynamic length optimizations on discrete systems specify the optimal temperature of each tray and consequently the amount of heat to be added or withdrawn in order to maintain that temperature.

Distillation Column Identification Using Artificial Neural Network

  Abstract: In this paper, Artificial Neural Network (ANN) was used for modeling the nonlinear structure of a debutanizer column in a refinery gas process plant. The actual input-output data of the system were measured in order to be used for system identification based on root mean square error (RMSE) minimization approach. It was shown that the designed recurrent neural network is able to pr...
