during natural gas processing, water in natural gas may cause to hydrates formation in pipelines which may lead to serious damages to process equipments. given the problems raised by present of water in natural gas, glycol solvent uses to remove water.in contact of glycol with gas always an amount of btex and voc absorb along with water, which on glycol recovery process, these substances separa...
determination of uranium in natural water and complex solutions using ion exchange chromatography: a combined procedure using ion exchange chromatography and uv-vis spectrophotometry techniques has been developed to measure uranum in natural water and complex solutions. after conditicing , one hundred milli liters of sample solutions have been passed through an ion exchange column,pachked with ...
atmospheric circulation patterns are responsible for drought and flood occurrences around the globe specifically in moderate mid latitude climates. while some circulation patterns are responsible for wet spells and floods as well, the drought events can be attributed to some other circulation patterns. therefore, identification and distinction of dry/wet producing patterns and the geographical ...
S torage and distribution systems for water and water-based fluids are both critical and ubiquitous in every industry, geography, and culture. Large scale industrial water handling systems require water storage and distribution for a range of applications from simple thermal control (cooling and heating systems) to Purified Water (PW) production and delivery. For more than 40 years, manufacture...
[1] The waters of sub-glacial Lake Vostok are thought to represent a unique biological habitat that has been out of contact with the atmosphere for millions of years. Although the water circulation within the lake will determine how nutrients are redistributed and hence where life may exist, the handful of existing studies conflict regarding whether the lake is stratified or well mixed, whether...

[1] High resolution (7 km) numerical simulations of the Gulf of Alaska circulation show an indirect effect induced by tidal forcing. Tides stir the water column more vigorously in the coastal ocean than in the Gulf’s interior, leading to denser waters there than offshore. This horizontal gradient induces a geostrophic current that, in general and in most regions, flows against the mean general ...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
A two-dimensional numerical model is used to study the response to upwellingand downwelling-favorable winds on a shelf with a strong pycnocline. During upwelling or downwelling, the pycnocline intersects the surface or bottom, forming a front that moves offshore. The characteristics of the front and of the inner shelf inshore of the front are quite different for upwelling and downwelling. For a...
Comparatively little work appears to have been done on the circulation in the intact living fish, particularly in the bony fish. This paper describes the circulation in the common eel using angiographic methods. This species is convenient as it can be fairly easily obtained in the autumn and winter, is tolerant of laboratory conditions and can survive for some time out of water. As no general d...
