“…The separation of gas-borne liquid droplets is today mainly based on mechanical separation. According to the recent review on droplet removal [ 3 ], separation is accomplished through four mechanisms, i.e., direct interception, inertial impaction, diffusional deposition and gravitation settling. Whether a certain mechanism takes place depends on the droplet substance and size, which defines the magnitude of the droplet momentum opposing the drag forces exerted by the gas flow.…”

In many energy and process engineering systems where fluids are processed, droplet-laden gas flows may occur. As droplets are often detrimental to the system’s operation, they need to be removed. Compact engineering solutions for the removal of entrained droplets are difficult to achieve with conventional flow control and heat transfer approaches and thus droplet removal devices are hence often costly and bulky. In this study, we analyzed the potential of a compact technology based on droplet capture and in situ evaporation by microwave heating. For that, we designed a microwave applicator containing a porous droplet separator for capturing and evaporating droplets. The application of open-cell ceramic foams as filter medium reduced 99.9% of the volumetric flow of droplets, while additional microwave exposure increases reduction to 99.99%. In addition, microwave-heated foams prevent droplet re-entrainment and structure-borne liquid accumulation within foams, thus avoiding water clogging and flooding.

Gas condensate reservoir exhibit complex phase behaviour once the pressure falls below the dew point pressure, fluids condense out of the gas, forming a condensate ring in the near wellbore region, which reduces gas well deliverability, and causes a reduction in the recovery factor from the reservoir. The complex phase behaviour of a gas condensate reservoir and compositional variations however, makes long term or future prediction of the reservoir performance extremely intricate. This paper thus, aims to conduct an optimization process that improves productivity from a gas condensate reservoir, and improves future predictability of reservoir performance. Firstly, a sensitivity analysis was conducted on the gas condensate reservoir., by applying the response surface methodology technique. The sensitivity analysis enabled a broader understanding of the simulation model, and identified parameters that were likely to have an effect on the consistency of the model. The next step involved conducting a history match of the reservoir production data recorded in the field against reservoir simulated production data. This involved calibrating the simulation model with actual production data from the reservoir, to ensure a perfect or near perfect representation of the reservoir performance, which was achieved by applying the Designed Exploration and Controlled Evolution (DECE). Once an accurate representation of the reservoir performance was achieved, the model was then used to perform production optimisation. Particle swarm optimisation technique was used in the optimisation of the reservoir, to provide information on the best production methodology for the reservoir that would improve profitability of the production process. A numerical study was conducted using the CMG 2021 compositional simulator, the CMOST AI simulator module, for various experimental studies, to determine proxy solutions that match the actual field history production data from the reservoir, and to predict the future performance of the reservoir. Obtained results showed an improvement in the recovery factor from the reservoir.
