Abstract:

We investigated the insertion of eddy promoters into a parallel-plate gas–liquid polytetrafluoroethylene (PTFE) membrane contactor to effectively enhance carbon dioxide absorption through aqueous amine solutions (monoethanolamide—MEA). In this study, a theoretical model was established and experimental work was performed to predict and to compare carbon dioxide absorption efficiency under concurrent- and countercurrent-flow operations for various MEA feed flow rates, inlet CO2 concentrations, and channel design conditions. A Sherwood number’s correlated expression was formulated, incorporating

The Ethiopian Jewish population of Israel numbers about 45,000.

These immigrants are currently undergoing a prolonged and difficult period of transition. Many fundamental aspects of their lives are changing, including religious practices (a mainstay of the community's traditional culture and identity), gender relationships, family dynamics, communal leadership patterns, health practices, educational and

Abstract:

In the frame of the EU funded project COMTES a closed sorption heat storage demonstrator based on sodium hydroxide as sorbent and water as sorbate, has been developed. The system operates on a hybrid basis. Heat is stored in sensible hot water tanks for diurnal storage and in the sorption system for seasonal storage. The benefits of both systems can be utilised, namely low charging and discharging losses in diurnal storage and low heat losses during storage time in seasonal storage. In the absorption heat storage system the heat and mass exchangers were developed on a tube bundle falling film

Abstract:

For the majority of applications involving detection of weak signals or thermal imaging, the quantum well infrared photodetector (QWIP) is designed to have the highest possible detectivity and operating temperature. The device parameters, such as the doping density, are chosen accordingly. In a different direction, the intrinsic short carrier lifetime (~ 5 ps) makes QWIPs well suited for high speed and high frequency applications. In such cases, since lasers are normally used, a high dark current can be tolerated. The most important parameter is then the absorption efficiency. For system simpl

Abstract:

Owing to the fact that the flow motion in piston pumps is irregular, it is not easy to achieve stable fluid flow in the pipelines (while adsorption and injection of fluid). Moreover, the beats occurring at times in the pipelines may lead to the failures in the pump operation and as a result to the breakdown of its operation regime. To solve these issues, provide continuous flow of injected liquid, as well as to eliminate the pressure fluctuations in fluid flow motion, it is recommended to use air devices in these pumps.

Abstract:

Gas absorption is a unit operation and separation process wherein soluble components of a gas mixture are dissolved in liquid solvent. This unit operation utilizes packing materials which play a vital role in providing surface area for gas and liquid contact. In this study, perlite from Lamba, Albay, Bicol was used in the production of packing material. The objectives of the study are to develop and characterize a packing material using a geopolymer derived from perlite and to design a packed column for the absorption of ammonia gas. The study determines the ideal perlite-Na2SiO3 concentration

Abstract:

The design and operation of an advanced absorption refrigeration unit (Thermochiller) as part of an industrial combined heat and power (CHP) system is presented. The unit is installed at a vegetable processing plant in Santa Maria, California. The overall integrated system includes the engine package with waste heat recovery, Thermochiller, cooling tower, and chilling load interface. The unique feature of the system is that both the exhaust and jacket heat are used to supply subfreezing refrigeration. To achieve the low refrigeration temperatures of interest to industrial applications, all com

Abstract:

For absorption cooling cycles using water as a refrigerant, H2O/LiCl mixtures are suitable for replacing conventional H2O/LiBr mixtures. In addition, membrane devices can be used to develop compact and lighter absorption systems, and they can operate with H2O/LiCl mixtures. The present paper describes an experimental evaluation of a membrane desorber/condenser operating at atmospheric pressure. Two operation modes were analyzed: continuous cycle operation and intermittent operation. For the first operation mode, the maximum desorption rate was 3.49 kg/h·m2, with a solution temperature of 90.3

Abstract:

A transparent Er3+,Yb3+:GdMgB5O10 single crystal with dimensions up to 24 × 15 × 12 mm was grown successfully by the high-temperature solution growth on dipped seeds technique from K2Mo3O10-based solvent. The grown crystal was characterized using PXRD, DSC and ATR techniques. Differential scanning calorimetry measurements and SEM analysis of the heat-treated solids revealed Er,Yb:GdMgB5O10 to be an incongruent melting compound with an onset point of 1087 °C. The absorption edge of the Er,Yb:GMBO sample is located in the region of 245 nm, which approximates a value of 4.8 eV. Absorption and emi

Abstract:

Simulation of the absorption column was studied. A new mathematic model was developed and tested against the actual operation data. From this, the accuracy of the model was proved. The pressure, temperature and gas composition on absorption effect was discussed. And from the point of the practical production, more optimized operating conditions of the nitric acid absorption tower were showed. It makes the dilute acid concentration increase by 3 percent and the exhaust emission of NOx decrease by 45ppm.

Abstract:

Substantial improvement of microvolume UV absorption spectrometry in sensitivity, robustness and ease of operation was achieved for routine biological applications. A unique microtubing-based absorption cell (208 μm internal diameter) featuring enhanced light transmission with a liquid core waveguide technique provided dramatically enhanced absorption sensitivity, proportional to the extended path length (50 mm, from the typical 1 mm), while robust measurement performance was attained by implementation of preventive measures against bubble trapping along the light path.

Abstract:

It was carried out the analysis of the heat utilization efficiency of the cogeneration module of the gas reciprocating engine with the cold produced by an absorption Li-Br chiller in an autonomous electric, heat and cold supply unit. It was revealed the presence of 30% heat losses of the total heat removed from the cogeneration gas reciprocating module and is due to the inconsistency of the joint operation modes of the absorption Li-Br chiller and the gas reciprocating engine. This inconsistency is caused by the contradictory conditions of their effective operation according to the temperature

Abstract:

Sea anchors are crucial for stabilizing fishing vessels and improving operations, specifically for jigging vessels. Their effective performance depends on design and material choice, with the canopy material playing a key role. We compared the drainage and drying rates of sea anchor canopies made from polyamide (PA) fabric, polyester (PES) fabric, and canopies designed with alternating strips of PA and PES (PA-PES) fabric to improve sea anchor performance, work efficiency, safety, and the stability of fishing operations. PA fabric had a fast initial draining rate due to high seawater absorptio
