Strong foam can be generated in porous media containing oil, resulting in incremental oil recovery; however, oil recovery factor is restricted. A large fraction of oil recovered by foam flooding forms an oil-in-water emulsion, so that costly methods may need to be used to separate the oil. Moreover, strong foam could create a large pressure gradient, which may cause fractures in the reservoir. ...

Use of amine solutions for the removal of acid gases such as carbon dioxide (CO2) and hydrogen sulfide (H2S) from natural gas is the most common method, and, in this process, operational problems because of foaming are reported. Foaming can lead to the entrainment of liquid into downstream process equipment and might result in a situation in which the process specification...

Aluminum foam is usually used as the core of composite materials by combining it with dense materials, such as in Al foam core sandwich panels and Al-foam-filled tubes, owing to its low tensile and bending strengths. In this study, all-Al foam-filled tubes consisting of ADC12 Al-Si-Cu die-cast aluminum alloy foam and a dense A1050 commercially pure Al tube with metal bonding were fabricated by ...

Aluminum foam that is lightweight with high specific strength, energy absorption and other characteristics can be used in aerospace, transportation, machinery manufacturing fields. The PCM method usually to prepare closed-cell aluminum foams. microsized foams made by this process solve the non-uniform pore structures caused liquid drainage during foaming of large surface morphology internal str...

There is an experimental study of samples monolithic foam concrete “SOVBI” with a density 205 kg /m 3 (grade D200) for combustibility. The evaluation criteria are the following values combustion characteristics: temperature increment in furnace, duration stable flame burning, sample mass loss. results show concrete: furnace 2 °C, burning 0 s, and 24.4%. Thus, kg/m noncombustible material. It pr...

The use of high-quality thermal insulation materials to improve the energy efficiency buildings is strongly increasing. Foam glass, a durable and porous material that resistant almost all substance effects, one best materials. Glass foaming complicated process affected by types agents used in initial composition mixture mode foaming. influence components - glass matrix agent discussed this pape...
