Article Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. These metrics are regularly updated to ...

Write a self-contained IEC 61131-3 Structured Text program to implement PID feedback control for the level in a distillation column. The output signal goes to an inlet valve feeding the column. Here ...

Taking advantage of the knowledge of top and bottom compositions of a distillation column, a dynamic neural network (DNN) is designed to identify the input-output relationship of the column. The ...

Abstract: The ultimate objective of this project is to design a Supervisory Control and Data Acquisition (SCADA) system that both monitors and controls one of the most important equipments in the oil ...

Refinery vacuum distillation units (VDUs) use ejector systems to establish and maintain distillation-column pressure for capturing valuable crude fractions and reducing vacuum residuum. Reliable ...

This project simulates a distillation column's behavior in real-time, using mass balance equations and theoretical stage analysis to compute distillate and bottom flow rates and compositions. Users ...

Izak Nieuwoudt reviews the hybrid schemes that can help process engineers reduce the energy use of their distillation processes DISTILLATION is the most prevalent technique for separating organic ...

Hybrid reactive-extractive distillation (RED) has been popular for separating azeotropic mixtures, as it combines the chemical reaction and physical azeotropic separation in a single unit operation.
