Later, comparative analysis in terms of capital cost, cost of manufacturing (COM), cost of biodiesel, and carbon emission is presented. This study shows that the biodiesel cost is linearly dependent on the cost of feedstock and process economics can be improved by converting glycerol to triacetin. The process with DWC and MVR resulted in a significant saving in COM (13.84%), biodiesel cost (18.24%), utility cost (45.44%) and carbon emissions (45.84%) than those in its counterpart.

Istratescu, T. Babadagli, A. Zadeh, M. Anderson, Chris Patterson","doi":"10.2118/199966-ms","DOIUrl":"https://doi.org/10.2118/199966-ms","url":null,"abstract":"\u0000 Heavy oil in reservoirs exists in the form of either water in heavy oil (w/ho) emulsions after primary production under water drive, or during secondary recovery methods such as water or steam injection. In many cases, the decision to apply any secondary or tertiary methods such as CO2 or CH4 injection depends on the understanding of the behavior of these gases in w/ho emulsions at reservoir conditions. Such an understanding can reduce the uncertainties in reservoir modeling by providing an adequate fluid model for reservoir simulation and history matching studies. In this paper, we focus on the interfacial properties, relative volume change, and PVT behavior of CO2 and CH4 in (w/ho) emulsions.\u0000 We first generated the (w/ho) emulsion using steam at 150oC. Next, the stability of our emulsion was tested using different criteria such as phase separation, viscosity of the produced emulsion compared with that of the starting oil, and the size and number of water droplets in the continuous medium. The experiments were run using two types of heavy oils that are collected from two representative fields in eastern Alberta, type A oil (27,000 cP) and type B oil (4,351 cP). A sensitivity analysis was performed to determine the impact of different operational variables such as water content in the emulsion, water pH, and flow rate; additionally, the role of asphaltene and resin in emulsion stability was investigated. The influence of water content in the emulsion was found to be critical and thus subsequent IFT and relative volume measurements as well as PVT analyses were conducted using emulsions of different water contents with a vol.% range from 10-70. The results were compared with a dead oil (no water) case. Two types of gases typically used to improve recovery in Alberta were tested: CO2 and CH4.\u0000 IFT and volume measurements indicate the existence of critical water content which dramatically changes the behavior of the system; generally, emulsions with water content below this critical value exhibit lower IFT than the original oil, and the IFT falls steadily as the water content increases. The trend is reversed when the water content exceeds the critical value and IFT starts increasing before it stabilizes. This process happens when the water content reaches a vol.% higher than 50; however, it remains below that of the original oil. Regarding volume ratio, there seems to be a clear relationship between pressure and volume ratio of the emulsion and CO2 system. Overall, volume ratio increases as pressure increases regardless of water content. In general, for experiments run with CO2, data suggests that water content affects the rate of expansion, but ultimately the final volume ratio remains the same.\u0000 The results of this work are significant in that they indicate the phase behavior of w/ho emulsions, and that CO2 and CH4 can vary considerably depending on the composition of oil and water content in the system.
