exergy analysis and response surface methodology (rsm) is applied to reduce the exergy loss and improve energy and exergy efficiency of acetic acid production plant. exergy analysis is run as a thermodynamic tool to assess exergy loss in reactor and towers of acetic acid production process. the process is simulated in aspen plus(v.8.4) simulator and the necessary thermodynamics data for calcula...

In this paper a design and implementation of a remote control system of a manipulator for weld inspection of nuclear reactor vessels are described. Based on the client-server TCP/IP software architecture, the presented control system enables an operator to perform the entire inspection procedure remotely over a network, avoiding exposure to dangerous radiation normally present in nuclear reacto...

We report a versatile capillary-based droplet reactor for the controlled synthesis of nanoparticles over a wide range of flow conditions and temperatures. The reactor tolerates large flow-rate differentials between individual reagent streams, and allows droplet composition to be varied independently of residence time and volume. The reactor was successfully applied to the synthesis of metal (Ag...

The simulation of plane impinging jets using the Lagrangian technique of smooth particle hydrodynamics is presented. In Section 1 the impingement of a plane jet onto a stationary surface is considered for Reynolds numbers 800, 4000, 8000 and Froude number 4. For each case, the height of the associated streams is measured and compared with both experimental and theoretical results. The agreement...

anaerobic treatment methods are more suitable for the treatment of concentrated wastewater streams, offer lower operating costs, the production of usable biogas product. the aim of this study was to investigate the performance of an anaerobic fluidized bed reactor (afbr)-aerobic moving bed bio reactor (mbbr) in series arrangement to treat currant wastewater.the bed materials of afbr were cylind...

Particles and condensing vapors contribute to the contamination of optical components solar thermochemical reactors including windows secondary concentrators result in severe reactor performance deterioration. We propose an impinging-jet a distinctive topology enhance aerodynamic-aided window protection. The vector fields on two-dimensional inner surfaces four conventional are analyzed for firs...

We show in this study that the combination of a swirl flow reactor and an antimicrobial agent (in this case copper alginate beads) is a promising technique for the remediation of contaminated water in waste streams recalcitrant to UV-C treatment. This is demonstrated by comparing the viability of both common and UV-C resistant organisms in operating conditions where UV-C proves ineffective - no...

Various types of metallic nanoparticles are being used, with coating or bare surfaces, for various biological and medical applications including the stent ones. Our recent experimental studies reveal that atoms of nanoparticles deform or elongate, more or less, depending on the either impinging electron streams from the external source or under the process of synergy. Present study reports meta...
