Batch distillation is an important separation process for small-scale production especially in pharmaceutical, specialty chemical and biochemical industries. Although batch distillation units require lower capital cost than continuous units, the unsteady state nature of the process, results in higher operating costs. Optimal control in batch distillation is a mode of operation which allows us t...

The understanding of the dynamic behavior of distillation columns has received considerable attention due to the fact that distillation is one of the ost widely used unit operations in chemical process industries. Thermally coupled distillation sequences (TCDS) can provide significant energy avings with respect to the operation of sequences based on conventional distillation columns. TCDS exhib...

Knowledge distillation is a potential solution for model compression. The idea is to make a small student network imitate the target of a large teacher network, then the student network can be competitive to the teacher one. Most previous studies focus on model distillation in the classification task, where they propose different architects and initializations for the student network. However, ...

Techniques such as ensembling and distillation promise model quality improvements when paired with almost any base model. However, due to increased testtime cost (for ensembles) and increased complexity of the training pipeline (for distillation), these techniques are challenging to use in industrial settings. In this paper we explore a variant of distillation which is relatively straightforwar...

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...

The improvement of an innovative dual membrane contactor process for treatment of combined hygiene and metabolic wastewater was investigated. Flux and solute rejection in the combined direct osmosis/osmotic distillation (DO/OD) process were enhanced by incorporating membrane distillation (MD) concepts into the process. Two new configurations were investigated: DO/MD, in which the driving force was

Eryngium caucasicum Trautv. (Apiaceae) is a perennial herbaceous plant with about one meter height, an endemic species that has been distributed in the northern parts of Iran. The plant leaves are normally used in medicine and food industries in Iran.The plant has several medicinal properties including enforcing generative power, diuretic, lenitive and appetizer. In this research differents par...

The determination of the alcoholic strength in spirits and liqueurs is required to control the labelling of alcoholic beverages. The reference methodology prescribes a distillation step followed by densimetric measurement. The classic distillation using a Vigreux rectifying column and a West condenser is time consuming and error-prone, especially for liqueurs that may have problems with entrain...

One approach to active learning involves taking students through a guided exploration process; one which ensures students will observe phenomena and then be asked questions intended to draw conclusions regarding the observations. In recent years, this has been called inductive teaching, but more recently the expression “inquiry-based instruction” or related terms have become more common. Concur...
