Optimizing for Viability – Revamping Vacuum Distillation Unit in a Brownfield Project

Vacuum Booster for Distillation Process

Preliminary Evaluation for Vacuum Membrane Distillation (VMD) Energy Requirement

The energy requirement of vacuum membrane distillation (VMD) with or without recirculation was modelled using both experimental results and theoretical data. The trends are generally consistent between the theoretical and experimental data. Thermal energy contributes the most to the total energy required for the VMD process. To lower the thermal energy cost, waste heat resource and heat recover...

Evaluating the Products Quality of the Vacuum Distillation Unit by Using MFCA Method

The distillation unit is one of the main units in refning companies, and it serves as the mother unit in any refnery with any degree of complexity. The optimization of this unit can increase productivity. In this study, the vacuum distillation unit of a refnery was selected as the case study. The shares of different expenses of this unit were clarifed using a novel material flow cost accoun...

Vacuum membrane distillation on a microfluidic chip.

A multilayered microfluidic chip used for vacuum membrane distillation is designed, fabricated and tested by rectification of a water-methanol mixture.

Self-optimizing Control: a Distillation Case Study

The following important question is frequently overlooked: Which variables should we control? The answer is related to finding a simple and robust way of implementing the optimal operating strategy. It is argued that the controlled variables should be those that that give “self-optimizing control”, which is when acceptable operation is achieved with constant setpoints for the controlled variabl...
