This study proposes an innovative biodiesel technology based on heat-integrated reactive absorption. Rigorous simulations embedding experimental results were performed in AspenTech AspenONE engineering suite to design this novel process and evaluate the technical and economical feasibility. The main results are given for a plant producing 10 ktpy biodiesel from waste vegetable oil with high fre...

The intrapulmonary distribution of inhaled ozone (O(3)) and induction of site-specific cell injury are related to complex interactions among airflow patterns, local gas-phase concentrations, and the rates of O(3) flux into, and reaction and diffusion within, the epithelial lining fluid (ELF). Recent studies demonstrated that interfacial phospholipid films appreciably inhibited NO(2) absorption....

In this paper a comprehensive approach is presented to improve power swings damping based on direct Lyapunov method. The approach combines superconducting magnetic energy storage (SMES) system with static synchronous compensator (STATCOM). Considering the energy absorption/injection ability of SMES, in transient states the combination exchanges both active and reactive powers with power system....

Distillation, absorption and extraction belong to the oldest and most mature separation technologies. They require often big columns and are energy intensive. In the chemical processing industry these separations are applied usually for the purification of the products, recycling of solvents or catalysts, etc. and are placed as a last step of a production process, after the chemical reactor(s)....

the use of low level laser to reduce pain, inflammation and edema, to promote wound, deeper tissues and nerves healing, and to prevent tissue damage has been known for almost forty years since the invention of lasers. this review will cover some of the proposed cellular mechanisms responsible for the effect of visible light on mammalian cells, including cytochrome c oxidase (with absorption pea...

as regards if curing stops for some time and then resumes again, then strength gain will also stop and reactive, in this study with choose suitable curing conditions after improper first curing (recurring) for normal and silica-fume concrete, effect of this curing conditions on strength and permeability was investigated. the results from tests such as compressive strength, capillary water absor...

The reactive oxidizing species in the selective oxidation of methane to methanol in oxygen activated Cu-ZSM-5 was recently defined to be a bent mono(μ-oxo)dicopper(II) species, [Cu(2)O](2+). In this communication we report the formation of an O(2)-precursor of this reactive site with an associated absorption band at 29,000 cm(-1). Laser excitation into this absorption feature yields a resonance...

Jui-Teng Lin New Vision Inc. Taipei, Taiwan AbstractThis paper presents analytic equations for the photoinitiator concentration and the dynamic absorption of the photosensitizer, methylene blue (MB), in an aquaculture system. The modelling is consistent with the measured data showing the dynamic absorption is a decreasing function of the light illumination time due to the depletion of MB concen...
