Operator erode

To use turboexpanders for condensing streams, the rotor blades must be shaped so that their walls are parallel at every point to the vector resultant of the forces acting on suspended fog droplets (or dust particles). The suspended fog particles are thus unable to drift toward the walls. Walls would otherwise present a point of collection, interfering with performance and eroding the blades. Hundreds of turboexpanders are in successful operation involving condensing liquids. 

The life and necessary maintenance of a gas turbine are heavily dependent upon both the operating regime and the fuel quality. Continuous firing on natural gas provides the optimum availability, which will be progressively eroded if the plant is subject to frequent inter-mptions (i.e. stops and starts) from both cold and hot conditions. With a maximum interval between inspections of some 8000 hours, it may be anticipated that the combustion section will require most attention. Every 16,000 hours (or less) the turbine section will need inspection. While a major inspection of the entire unit will be necessary every 31,500 hours. Under optimal conditions, the... 

Advection is important in fragmentation processes, and an initially homogeneous system may evolve spatial variations due to spatially dependent fragmentation rates. For example, Fig. 36 shows the spatial distribution of eroded clusters in the journal bearing flow operating under good mixing... 

Erode applied to a mask peels off a layer from every white island in the mask. Dilate does (almost) the inverse if erode has not managed to delete a white island completely, it is almost restored. The median operator reduces noise in the image without broadening the peaks. The operator is frequently addressed median filter . 

The ISO protocol for the biochemical response EROD (ISO 23893-2/AWI) as a recent example of a bioanalytical (biomarker) [49,50] method standardised under ISO for fish needs harmonisation with the other test systems and between the laboratories (users) before implementation. Use of biomarkers (biochemical responses) in multi-arrays for environmental monitoring according to Hansen et al. [50] is complementary to chemical analysis since they can alert for the presence of ecotoxic compounds. Bringing into the WFD, the effect-related approaches concerning bioassays and biomarkers are only relevant in the context of the QN of environmental relevant substances and the good chemical status. But it is rather difficult to transfer the monitored biochemical responses or biomarkers into an operational effect-related standard. They serve as the basis for environmental protection against hazardous substances. In relation to... 

Hybinette A process for extracting nickel from sulfide ores. The nickel ore that occurs in Canada is a mixture of the sulfides of nickel, copper, and iron. Several methods have been used to separate these metals. In the Hybinette process, the ore is first smelted in a blast furnace, yielding a nickel-copper matte i.e., a mixture of their lower sulfides). This is roasted to remove sulfur and leached with dilute sulfuric acid to remove copper. The resulting erode nickel oxide is used as the anode of an electrochemical cell. The nickel deposits on the cathode, which is contained in a cloth bag. Precious metals collect in the anode slime. The process was invented by N. V Hybinette in 1904 and operated at the Kristiansand refinery, Norway, from 1910. 

Moebius An electrolytic process for removing gold and platinum from silver. The erode metal, known as Dore, is used as the anode. The cathodes are of silver or stainless steel. The electrolyte is a diluted solution of silver nitrate and nitric acid. Gold and other metals collect as anode slimes. Invented in Mexico by B. Moebius, first operated there in 1884, and subsequently widely operated in Germany and the United States. See also Balbach, Thum, Wohlwill. 

A variety of human activities increase erosion and sedimentation rates. For example, soil typically erodes from cultivated land five to 10 times as fast as from noncultivated land. Construction sites lose soil 100 times as fast and mined land more than 500 times as fast as land that is undisturbed. Besides greatly increasing water pollution, this erosion accelerates the loss of valuable farmland. By some estimates, as much as 3.3 billion tons (3 billion metric tons) of topsoil is lost to such processes in the United States each year. Overall, the major anthropogenic sources of erosion (and, as a consequence, sedimentation) are certain types of agriculture (such as row cropping), livestock operations, logging, flooding from developed land, and construction projects. 

But wet steam is bad for a jet, even when it does not cause the jet to freeze. Mainly, wet steam causes erosion of the steam inlet nozzle. Erosion of this nozzle is the main reason why jets undergo mechanical deterioration. As the nozzle erodes, it allows more steam to pass through into the diffuser. The diameter of the diffuser is designed to operate with a certain steam flow. If that design steam flow is exceeded, the diffuser operation suffers. Also, the downstream condenser pressure will also increase.
