    Abstract

    An experimental investigation of the volumetric heat transfer coefficient in a three-phase direct contact condenser was carried out. A 75-cm long cylindrical Perspex column with a 4 cm diameter was used. Only 48 cm of the column was utilised as the active direct contact condensation height. Pentane vapour at three different initial temperatures (40°C, 43.5°C and 47.5°C), with differing mass flow rates, and tap water at a constant initial temperature (19°C) with five different mass flow rates were employed as the dispersed phase and the continuous phases, respectively. The results showed that the volumetric heat transfer coefficient increased with increasing mass flow rate ratio (variable dispersed phase mass flow rate per constant continuous phase mass flow rate), the continuous phase mass flow rate and holdup ratio. An optimal value of the continuous phase mass flow rate is shown for an individual dispersed phase mass flow rates. This value increases with increasing vapour (dispersed) phase mass flow rate. Furthermore, it was observed that the initial driving temperature difference had no effect on the volumetric heat transfer coefficient. While, the temperature gained by the continuous phase has a considerable effect.

    Abstract

    An experimental and analytical investigation for the temperature distribution prediction of a three-phase bubble-type direct-contact condenser conducted, using a short Perspex column with 4cm internal diameter and 70cm height as a direct contact condenser. Vapour pentane and water were exploited as dispersed phase and continuous phase respectively. The effect of mass flow rate ratio (43.69%, 22.97%, 12.23%, 8.61% and 6.46%) and initial dispersed phase temperature (37.6°C, 38.4°C and 41.7°C) on the direct contact condenser output were studied. Linear temperature distributions along direct contact condensers were found experimentally, except at mass flow rate ratio 43.69% and with less magnitude at 22.97%, for different initial vapour temperatures, while theoretically this behaviour is purely linear. The results showed that the mass flow rate ratio and the hold up have a dominant effect on the direct contact condenser output. On the other hand, the initial vapour temperature had a slight effect on the direct contact condenser output temperature which indicates that the latent heat is controlled in the exchange process. The analytical model is based on the one-dimensional mass and energy equations. New expressions for average heat transfer coefficient and two-phase bubbles relative velocity are derived implicitly. Furthermore, the model correlated very well against experimental data obtained. © 2013 Elsevier Ltd.

    Abstract

    Membrane distillation (MD) is a recent and unique separation technology, in use in the process industry. The process of separation in MD involves the simultaneous heat and mass transfer through a hydrophobic semi permeable membrane, using thermal energy. Consequently a separation of the feed solution into two components - the permeate or product and the retentate or the return stream occurs. MD utilises low grade or alternative energy, e.g., solar energy, geothermal energy, etc., as a source and is the most cost effective separation technology. Hence the process has come to acquire the attention and interest of researchers, experimentalists and theoreticians all over the world. This article is a comprehensive review of the prominent research in the field of MD technology, including its basic principle, MD configurations, area of applications, membrane characteristics and modules, experimental studies involving the effect of main operating parameters, MD energy and economic, fouling and long-term performance.

    Abstract

    When primary oil production decreases in a field because of reduction in original pressure, water is usually injected to increase oil production. Injected water in special wells (injection wells) forces the oil remaining in certain layers to emerge from other wells (production wells) surrounding the injector. This technique, commonly called secondary recovery, contributes in extracting up to 50% of the original oil in place. Although this technique was first used in old reservoirs where oil production had decreased, it is today a common practice to begin the exploitation of new wells with fluid injection as a way to optimize oil recovery. For this reason, the name secondary recovery is being replaced by the more general term water flooding. Efficiency of the water flooding process is highly dependent on the rock and fluid characteristics. In general, it will be less efficient if heterogeneity is present in the reservoir, such as permeability barriers or high permeability channels that impede a good oil displacement by the injected water [1]. On the other hand Most of the scales found in oil fields forms either by direct precipitation from the water that occurs naturally in reservoir rocks, or as a result of produced water becoming oversaturated with scale components when two incompatible waters meet downhole. The present study attempts to establish the tracer technology as a reliable source of information in scaling experiments and reservoir evaluation such as reservoir heterogeneity. In a series of calcite scaling experiments in sand, Ca2+ was used as a tracer to monitor the CaCO3 precipitation. The results show that the introduction of tracer technology, for the first time in scaling experiments in porous media, has been successful [3]. Copyright 2006, Society of Petroleum Engineers.

    Abstract

    An experimental investigation of heat exchange in a three-phase direct contact condenser was carried out using a 70-cm-high Perspex tube with a 4-cm inner diameter. The active direct contact condenser comprised 48 cm. Pentane vapour at three initial temperatures (40℃,43.5℃, and 47.5℃) and water at a constant temperature (19℃) were used as the dispersed and continuous phases, respectively, with different mass flow rate ratios. The results showed that the continuous phase outlet temperature increased with increasing mass flow rate ratio. On the contrary, the continuous phase temperature decreased with increases in the continuous mass flow rate. The initial temperature of the dispersed phase slightly affected the direct contact condenser output, which confirms a latent phase effect in this type of heat exchanger.
