“…Superhydrophobic surfaces can allow water droplets to roll off easily from a surface, thereby preventing the accumulation of water . This special non‐wettability of engineering plastics including PI can protect against mechanical damages of their surfaces and, at the same time, it also can offer corrosion‐resistant property as well as anti‐fouling properties, which are urgently needed in practical engineering field especially in harsh working environment . The construction of superhydrophobic surfaces (water contact angle > 150°) of PI could not only solve these water uptake problems, but also prevent chemical reactions and electrical conduction of electric packaging materials .…”

Porous interior structured polyimide (PI) films with a hierarchical surface are fabricated from 4,4′‐(hexafluoroisopropylidene)diphthalic anhydride and 4,4′‐oxydianiline by a water vapor induced phase separation process under a humid environment. Superhydrophobic properties with a water contact angle of 161° are obtained using the hierarchical surface morphology, which can be adjusted from flower‐like to wrinkle‐shape particles facilely by changing the relative humidity. The dielectric constant (k) of the PI film decreases sharply from 2.8 (film prepared under dry conditions) to ≈1.9 (film prepared under humid conditions) because of the interior porous structure and fluorine‐containing framework. Both a low‐k and superhydrophobicity are very important parameters for PI films in microelectronic and insulating applications.

Process Design of Ammonia Separation for Nitrification Control in Aeration Basins at an IKORC’s Oily Wastewater Treatment Unit

In the current decades, water shortage is well understood as one of the main limiting factors for oil industry development all over the world. One of the available and reasonable solutions is reusing wastewater. The oily wastewater treatment unit of the IKORC oil refinery provides a portion of the makeup water for cooling towers, applying physical, biological, and chemical treatments. Ammonia shocks are the only crisis that disrupts the nitrification process. This condition eventuates in destroying the microorganisms of aeration basins and leads to a high ammonia containing effluent. In order to protect the aeration process, it is mandatory to apply a suitable system for removing excess ammonia. In this study, at first, ammonia removal history is reviewed. Then quantity and quality of the oily sewer are investigated. Because of high volatility of ammonia contamination and high TDS, a stripping tower with air is selected among diverse solutions. Taking into account the principles of project econometrics, operating parameters such as stripping factor, pressure drop, tower volumetric flow rate, and number of towers are determined. Then, the process is designed and its environmental survey is conducted. Finally, calculating indices proved that this project is economically profitable in addition to its environmental benefits.

“…17 Other emerging applications for electrospun meshes include air ltration [18][19][20][21][22] and oil-water emulsion separation. 23,24 In electrospinning, a syringe is loaded with a polymer that has been dissolved in a volatile solvent. A high voltage is then applied between the needle connected to the syringe, and the collector plate (Fig.…”
