... dehumidification (HDH) process was designed and constructed to meet requirements of energy efficiency and high tolerance to inlet water chemistry. Through the process, water is evaporated at an elevated temperature (175°F/80°C) in a flowing air stream, followed by cooling and capillary condensation resulting...

... tested included modeling downhole condensation or vaporization of water, a correction for water density, use of a regression technique to minimize error in a program that was written to allow input constants to help adjust predications to measurements, and adding multiphase flow regimes in the two phase...

... Abstract The modified black-oil model (MBO) was tested against the fully compositional model and performances of both models were compared using various production and injection scenarios for a rich gas condensate reservoir. We evaluated the performance of MBO model by investigating...

... Robinson EOS characterisation that represents the thermodynamics of a well documented condensing/vapourising EOR process 1 . Also, a five stage flash sequence that mimics typical field process facilities was used to stabilise the reservoir fluids to surface conditions. Despite the effectiveness...

... extended to describe this override behaviour, by using a semi-steady state approximation for the heat transfer at the steam condensation front (SCF). In the absence of heat losses the ensuing equations are completely analogous to the equations for oil-water flow. We have also incorporated heat losses...

... on steam displacement were also included in the model. Semi-analytical calculations of saturation and pressure distributions are presented to illustrate the mechanisms. It was shown that under most conditions, the Buckley-Leverett displacement velocity is significantly faster than the steam condensation...

... using a gas chromatograph. Three natural crude oils with gravities ranging from 17° to 45° API (sp. gr. 0.80 to 0.90) were chosen for the study. The results indicate that the CO 2 -crude oil interactions can be divided into three stages: (a) CO 2 condensation, (b) extraction-condensation and (c...

... do not differ significantly from the steam table values. Significant liquid pressure lowering does result. Also the transition from capillary condensation to thin film adsorption may be identified from the liquid pressure lowering curves. Applications to other systems in thermodynamic equilibrium...
