Studies on Mechanical, Thermal, Physical Properties and Characterisation of PLA-EVA Blend with Microclay and Product Development
Abstract: PLA-EVA (70:30 wt. %) with microclay (1, 3, 5 wt. %) was also melt blended using Glycerol (1%) was used as compatibilizer in a twin screw compounding extruder. Then test specimens were prepared by an injection molding machine. Mechanical, thermal and physical properties were evaluated. As microclay content was increased, the tensile strength, elongation at break and tensile modulus were slightly decreased but higher than that of PLA-EVA (30 wt. …

Evidence of PDMS-based foam control agent mechanism on crude oil foams
Abstract: Crude oil foam is a frequent problem faced in oil production operations that can cause the reduction of the separator efficiency, separator overflow, carry out of liquid by the gas stream, and other serious problems. Among the techniques used to attenuate foams in crude production, the injection of chemical additives is still considered one of the most efficient. However, the effectiveness of a foam control agent (FCA) is limited to …

Mechanism of Intensive Gas and Fluid Mixture in the Process of Vibroturbulization and Its Technological Applications
Abstract: Previously conducted experimental studies have established that in a certain narrow frequency range and upon reaching a certain value of the amplitude of water oscillations in a sealed vessel with above-water air shell, subjected to vertical vibration, a resonant phenomenon occurs, called “vibroturbulization”, leading to intensive mixing of media of different density. The studies carried out were purely experimental in nature and could not reveal the physicochemical mechanism of occurrence, …
