Solids-preventing agents are often hydrocarbons that are heavier than the natural gas, with a preference for butane.…”

AbstractFossil fuels are still a necessary and important part of modern living, keeping cars running and houses heated for example. As demands have risen and reservoirs of oil and natural gas have depleted, it has become increasingly more important to tap in to fields that were once classified as undesirable. Sour fields, fields high in acidic gases such as hydrogen sulfide and carbon dioxide, are one such option. There are many difficulties and dangers associated with working sour fields, such as toxicity of the sour gases, hydrate formation and corrosion of equipment that have prevented these resources being used in the past. Many varied methods of overcoming these problems have been developed, from removing the sour components to inhibiting their effects. This review highlights the major issues raised by sour fields as well as a wide range of solutions in use today.

“…Figure 6 shows the theoretical limit of CO 2 separation without solid formation. Maqsood et al (2014) predicted the solid formation in the distillation column inside the convergence loop. It is evident from Figure 6 that, with the increase in the distillation column pressure, solid formation can be avoided, but the CH 4 losses will be higher along with the decrease Brought to you by | University of Pittsburgh Authenticated Download Date | 1/5/15 7:22 AM Table 3 PVTX experimental data of CO 2 mixtures.…”

Fossil fuels are the major contributors to the emission of anthropogenic carbon dioxide (CO 2 ) to the atmosphere, rendering global warming a challenging issue to the researchers and industries. Although natural gas has been recommended as a clean fuel compared to other fossil fuels, geological sources of natural gas are not free of impurities. Economical commercialization of natural gas with high sour gas contents as well as facilitating the geosequestration of sour gases for enhanced oil recovery (EOR) need several environmentally sound and cost-effective gas separation methods. Moreover, stringent restrictions should be drawn to mitigate the unfettered greenhouse gas emissions to the atmosphere. In the present study, existing low-temperature conventional CO 2 capture methods, namely, cryogenic distillation process along with emerging nonconventional and hybrid methods, have been demonstrated. Also, the limitations and operational conditions during the application of these processes have been mentioned. The future prospects of the emerging technologies have been compared with conventional methods. Hybrid cryogenic distillation networks for multiproduct industrial production of different hydrocarbons and CO 2 products at higher pressures of 40 bar and above showed promising potentials. A concise classification and summary of innovative emerging technologies along with conventional methods has been presented in this paper for possible future commercial exploitation.

“…Other techniques of energy-efficient distillation include the internally heat-integrated distillation [7][8][9][10], hybrid cryogenic distillation [11], solar energy utilized distillation [12], and better controlled distillation [13]. In conventional distillation, the condenser recovers the heat supplied through a reboiler, but the temperature of the recovered heat is lower than the reboiler temperature.…”

Energy saving distillation using a horizontal distillation column was experimentally examined, and the improvement of the technique has been investigated by utilizing a rectangular column. The rectangular column provides larger cross-sectional area for increased throughput and larger heat transfer area for diabatic operation. The proposed technique saves about 13.6% of energy demand compared with the vertical distillation column calculated from the HYSYS simulation. The result indicates that improved capacity of feed processing is possible with the rectangular column.
