Isotopic Separation

Within the research conducted at our Institute of Cryogenic and Isotopic Technologies (ICSI), is developed a project entitled "Innovative CECE process solution to promote a new technology for decontamination of liquid waste, tritium low concentrated and deuterium recovery”. The main objective of the project carried out within our team is to promote an innovative solution of CECE isotopic separation process (Combined Electrolysis and Catalytic Exchange), part of a new technology for decontamination of liquid waste, poorly concentrated in tritium, generated by nuclear reactors, ensuring increased recovery of the isotope deuterium and tritium. This paper presents the current stage of an innovative CECE isotopic separation process solution, and also the mathematical model developed for the simulation of hydrogen isotope separation processes through the CECE process and a theoretical analysis based on numerical data resulting from the simulation of two CECE plant operating mode.

Efficiency Comparison

In the paper, the comparison between the efficiency of using artificial intelligence methods and the efficiency of using classical methods in modelling the industrial processes is made, considering as a case study the separation process of the 18O isotope. Firstly, the behavior of the considered isotopic separation process is learned using neural networks. The comparison between the efficiency of these methods is highlighted by the simulations of the process model, using the mentioned modelling techniques. In this context, the final part of the paper presents the proposed model being simulated in different scenarios that can occur in practice, thus resulting in some interesting interpretations and conclusions. The paper proves the feasibility of using artificial intelligence methods for industrial processes modeling; the obtained models being intended for use in designing automatic control systems.

Innovative Solution

With the continual convergence of analogue technologies with those either simulated or implemented in digital based equivalents, future benefits usually involve better reliability and lower costs. As current technical limitations are removed, the literature does not show any large scale assessment of the legal and security implications of the removal of cables in this digital world or the effect of a move toward wireless transmission in this context. Neither Voice Over Internet Protocol (VoIP) nor IEEE 802.11b is new technology, but the combination of these services to provide a primary telephone network for small regional centres is an innovative solution to rural telecommunication problems.

A new technology has been currently developed for the removal of heavy metal waste in water, called biosorption. Biosorption technology has been widely used to remove heavy metals from liquid waste. The potential biomass which can be used as bio sorbent was activated coconut husk waste. By using the continuous flow method and activated coconut husk as bio sorbent, the obtained optimum flow rate and bed height of bio sorbent were 2 mL/min and 0.1 g with adsorption capacity of 188.322 mg/g.

Abstract Separation process is very crucial in bioethanol production as it consumes the highest energy in the process. Unlike other works, this research systematically designed a suitable separation process for bioethanol production from corn stover by using thermodynamic insight. Two separation processes, i.e., extractive distillation (case 2) and pervaporation (case 3), were developed and compared with conventional molecular sieve (case 1). Process design and simulation were done by using Aspen Plus program. The process evaluation was done not only in terms of energy consumption and process economics but also in terms of environmental impacts. It was revealed that pervaporation is the best process in all aspects. Its energy consumption and carbon footprint are 60.8 and 68.34% lower than case 1, respectively. Its capital and production costs are also the lowest, 37.0 and 9.88% lower than case 1.

The present work proposes and analyses the solution for seismic behaviour of GFRP (Glass Fiber Reinforced Polymers) applications to evaluate the performances respect to dynamic actions considering the global effect on historical structures. The good strength-self-weight relationship defines the GFRP pultruded profile as an efficacious and innovative solution for structural rehabilitation of historical buildings. The composite material with polymeric matrix, FRP (Fiber Reinforced Polymers), is widely used in civil engineering as sheets, bars and strips. Recently a new technology was adopted to improve the structural response with limited increment of dead load with reversible and independent solution.
