This work summarizes methods for prevention of gas pipeline clogging by natural gas hydrate formation – with emphasis on development of environmentally friendly hydrate inhibitors. The work highlights advantages and disadvantages of current solutions and encourages future studies on new type of inhibitors based on ice-structuring proteins.

More than one year has passed since refrigerant for refrigerator was changed from CFC12 to HFC134a. Long term reliability of refrigerator in HFC134a refrigerant system is mainly dependent on lubrication of moving parts of compressor and clogging of capillary tube. To maintain better practical reliability in components in compressor such as refrigeration lubricant,metallic materials and motor in...

The issue of emitter clogging is a common phenomenon in drip fertigation systems, which causes uneven irrigation and fertilization. However, efficient environmentally friendly methods are scarcely available for alleviating clogging. In the present study, we investigated anti-fouling efficacy three magnetic field strength levels (0, 0.4 T 0.6 T) on systems. Our results show that magnetized water...

We present a new experimental approach to further understand the injectivity impairment due reinjection of produced water in an oilfield, containing residual oil and solids. A unique microfluidic setup with imposed flowrate is characterized by excellent reproducibility allows one determine kinetics external cake formation propagation damage inside porous medium, similar what happens at injectio...

We report on a performance study of a French-Canadian fiddler. The fiddling tradition forms an interesting contrast to classical violin performance in several ways. Distinguishing features include special elements in the bowing technique and the presence of an accompanying foot clogging pattern. These two characteristics are described, visualized and analyzed using video and motion capture reco...

In land reclamation projects, the vacuum preloading method has been widely used to strengthen dredged fills by removing water. However, during improvement process, clogging inevitably occurs in drains and soils, hindering water drainage causing inhomogeneous consolidation results. Therefore, it is essential evaluate effect of on behavior slurry at different radii. this study, analytical solutio...
