Proper air filtration is critical to the overall performance and reliability of gas turbines. The latest evolution in the filtration industry is the use of nanotechnology in this field. With this technique, the surface of large cellulosic or synthetic textiles (usually 10 to 30 micrometers in diameter) is covered with a layer of ultra-fine textiles (typically 50 to 400 nanometers in diameter). There are two different methods for separating particles in the filter paper structure.
In-depth filtration, in which particles are separated in different layers of paper according to their size; and surface filtration, in which all particles are separated on the surface of paper. In Behran Co. before pleating process, the filter paper is covered with a layer of Polyamide textiles with diameter of less than 100 nanometer by using electrospinning process.
More efficient heat transfer systems are increasingly preferred because of the accelerating miniaturization, on the one hand, and the ever-increasing heat flux, on the other hand. The poor heat transfer properties of the common fluids like water compared to most solids is a primary obstacle to the high compactness and effectiveness of heat exchangers. Passive enhancement methods such as enhanced surfaces are often employed in thermo-fluid systems. Therefore, the development of advanced heat transfer fluids with higher thermal conductivity and improved heat transfer is in strong demand. Nanofluids are heat transfer liquids with dispersed nanoparticles. The effectiveness of heat transfer enhancement has been found to be dependent on the amount of dispersed particle, material type, particle shape, etc.
Catalytic reforming is a major conversion process in petroleum refinery which converts low octane naphthas into higher octane reformate products for gasoline blending and aromatic rich reformate for aromatic production. To perform the process correctly and efficiently, as well as to prevent coke making, the process structure and catalyst must be selected optimally. The efficient structure of the reforming reactors is continues catalytic reforming (CCR). In this process the catalyst is key component. The γ–alumina based catalyst is amongst the catalysts that has a long history in catalytic reforming. In naphtha reforming, γ–alumina is responsible for acidic interactions; moreover, the dehydrogenation reactions are performed by some metals which are impregnated to the catalyst. Therefore, alumina-based catalyst is a very suitable candidate for catalytic reforming.
Contrary to the compact structure, the presence of surface cavities with nanometer and micrometer dimensions makes the tile sensitive to the stain and penetration of the contamination. Colloidal nano silica acts as a binder, polishing agent and coating to fill these pores and prevent the stains and dirt from penetrating into the surface.
Concrete is unique in construction and it is only an exclusive product for trading; so it involves a significant share of research and development, and income in the industry to itself. Concrete, a multi-phase, complex and nanostructured material, is a composite structure mainly composed of cement and water. Nanoscience and nanoengineering of concrete are phrases which describe two essential approaches regarding the application of nanotechnology in concrete. Up to now, concrete has been primarily known as a structural material. Nanotechnology is capable of making a multi-functional material from concrete. Concrete can be nanoengineered by incorporating nanoscale building blocks, nanoparticles, nanotubes, etc.
