The Antarctic plateau provides the best terrestrial sites for infrared and sub millimetre astronomy In this paper we examine the relative importance of temperature aerosol content and precipitable water vapour to determine which parameters have the greatest in uence on atmospheric transmission and sky brightness We use the atmospheric modelling program MODTRAN to model the observed sky spectrum...

Modeling distillation is one of those activities that distinguish chemical engineers from their peers. Modeling distillation is something that chemical engineers have been doing continuously (or in batches) for 113 years. Despite predictions of an earlier demise, distillation modeling is not dead. And, while such forecasts have played a role in the lessening of financial support available for d...

Catalytic distillation is a technology that combines heterogeneous catalytic reaction and the separation of reactants products via in single reactor/distillation system. This process catalysis, kinetics, mass transfer to obtain more selective products. The catalyst provides sites for reactions porous surface liquid/vapor separation. advantages are energy savings, low waste streams, longevity, h...

We construct new entanglement distillation protocols by interpolating between the recurrence and hashing protocols. This leads to asymptotic two-way distillation protocols, resulting in an improvement of the distillation rate for all mixed Bell diagonal entangled states, even for the ones with very high fidelity. We also present a method how entanglement-assisted distillation protocols can be c...

Distillation is an essential separation process in the chemical and petrochemical industry. The distillation process is a highly nonlinear, complex, interactive and non -stationary, therefore its control is difficult. In the present work an adaptive neuro-fuzzy controller is designed to control a binary distillation process. A conventional PID controller is also designed for comparison purpose....

Distillation is a widely used separation method in the process industries and it is the largest energy consumer among individual process units. Improvement of energy efficiency in distillation systems is still an active research field. Among the issues concerned with the improvement of energy efficiency of distillation systems, the optimal design and synthesis A SHORT Note ABOUT ENERGY-EFFICIEN...

Chemistry in Titan’s N2–CH4 atmosphere produces complex organic aerosols. The chemical processes and the resulting compounds are still far from understood, although extensive observations, laboratory, theoretical simulations have greatly improved physical constraints on atmosphere. Here, we conduct a series of Titan simulation experiments with gas mixtures investigate effect initial CH4 ratio, ...
