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 ...
PURPOSE To develop a liquid crystal polymer (LCP)-based, long-term implantable, retinal stimulation microelectrode array using a novel fabrication method. METHODS The fabrication process used laser micromachining and customized thermal-press bonding to produce LCP-based microelectrode arrays. To evaluate the fabrication process and the resultant electrode arrays, in vitro reliability tests an...
In this current era, increasing computing power, effort to reduce prototypes’ cost and time, and shorten design-toproduct time urges the need of numerical computation. Higher cooling’s load or requirement is attributed by higher power of engine. Also, higher quantity of heat exchangers and vehicles’ styling resulted limited space at vehicles’ hood. These factors have caused the design job of ve...
Cryogenics is the continuation of heat treatment and is the last step that completes the thermal treatment processing of metals. After ferrous steel part/s are heat-treated and tempered, the part’s grain structure can be improved by subjecting the part to a deep cryogenic temperature (–320 °F) soak. The process involves taking the parts down from room temperature to –70 °F to –100 °F using dry ...
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 ...
