Problem statement: We have recently introduced several important improvements in the measurement of distillation curves for complex fluids. The modifications include a compositionexplicit data channel for each distillate fraction and temperature measurements that are true thermodynamic state points that can be modeled with an equation of state. The composition-explicit information is achieved w...

Distillation separates compounds by the variation in how effortlessly they vaporize. The two main types of standard distillation comprise unremitting distillation and batch distillation. Unremitting distillation, as the name says, unremittingly takes a feed and separates it into two or more products. Batch distillation takes on lot (or batch) at a time of feed and splits it into products by sel...

An important amount of work exists on the topic of optimal operation and control of batch distillation though it is still based on the assumption of an accurate process model being available. While this assumption is valid from a theoretical point of view, there will always remain the challenge of practical applications. Reinforcement Learning (RL) has been recognised already as a particularly ...

Conventional deep learning classifiers are static in the sense that they are trained on a predefined set of classes and learning to classify a novel class typically requires re-training. In this work, we address the problem of Low-Shot network-expansion learning. We introduce a learning framework which enables expanding a pre-trained (base) deep network to classify novel classes when the number...

Consider binary and ternary mixtures of aromatic compounds composed of benzene/toluene and benzene/toluene/p-xylene, respectively. The present study shows how one can apply both mass and energy balance equations in order to understand the separation of such ideal mixtures by distillation. An adiabatic flash distillation problem is solved graphically for a mixture composed of benzene/toluene. Ri...

The simulation of batch distillation columns during start-up operations is a very challenging modelling problem because of the complex dynamic behaviour. Only few rigorous models for distillation columns start-up are available in literature and generally required a lot of parameters related to tray or pack geometry. On an industrial viewpoint, such a complexity penalizes the achievement of a fa...

Motivated by the problem of designing quantum repeaters, we study entanglement distillation between two parties, Alice and Bob, starting from a mixed state and with the help of “repeater” stations. To treat the case of a single repeater, we extend the notion of entanglement of assistance to arbitrary mixed tripartite states and exhibit a protocol, based on a random coding strategy, for extracti...

The discrepancy between central Greenland borehole temperatures and the isotopic composition of Last Glacial Maximum ice can be explained by a shift in the •5180-T relationship for the hydrological cycle linked to cooler tropical temperatures. This concept is illustrated using a simple Rayleigh distillation model. An estimate for o•=A•5180/AT (LGM-Holocene) of-0.37 %o/øC is determined with a si...
