Amine is one of candidate solvents that can be used for CO 2 recovery from the flue gas by conventional chemical absorption/desorption process. In this work, we analyzed the impact of different amine absorbents and their concentrations, the absorber and stripper column heights and the operating conditions on the cost of CO 2 recovery plant for(More)
A new network representation to study the impact of capital and research & development (R&D) investment decisions on the evolution of biomass to commodity chemicals technologies is presented. The corresponding mathematical programming formulation is developed. The model is solved for a simplified ethylene production scenario to demonstrate its ability to(More)
This work focuses on designing the optimum raceway pond by considering the effects of sunlight availability, temperature fluctuations, and harvest time on algae growth, and introduces a dynamic programing model to do so. Culture properties such as biomass productivity, growth rate, and concentration, and physical properties, such as average velocity, pond(More)
Utilization of biomass as a feedstock in chemical process industry (CPI) will require investments in research & development (R&D) as well as for capacity expansions. To study the effects of these investments on the evolution of biomass to commodity chemicals (BTCC) system, a new Stage-gate Representation is introduced to complement the network(More)
For to pursue and to stimulate adequate shapes of prevention of the risk of falls from the high, the ASL of the province of Bergamo has approved of the moderniization of the R.L.I. that it introduces the obligation of the predisposition of structural elements that they favor the successive one rests in work and 1 use of DPI. It has been activated,(More)
Fouteen "flush"-ended segments originate from the action of the restriction endonuclease Hae III of Haemophilus aegiptius on the DNA of the colicinogenic factor ColE 1 (A. Oka and M. Takanami, Nature, 264, 191, 1976). They are joined by the T4 polynucleotide ligase. The reaction can be monitored by gel electrophoresis, electron microscopy and resistance to(More)
