Oxides of sulfur and nitrogen are the main air pollutants that are also responsible for acid rain. Excessive sulfur content in petroleum fractions such as naphtha, in addition to causing air pollutants, can corrode tanks, reactors, pipes and fittings. Currently desulfurization is carried out using desulphurization catalysts adjacent to hydrogen; thus at a certain temperature and pressure, as well as a specific proportion of hydrogen, sulfur atoms convert to hydrogen sulfide. Catalysts based on γ–alumina are commonly used for desulphurization. Alumina has various applications including ceramic membranes, paints, refinery and chemical catalysts, pollution control and base catalyst. The mesoporous γ–alumina with pore diameter in the range of 2 to 50 nm due to its high specific surface area, high porosity, good thermal stability and suitable pore distribution is used as the most common base catalyst in desulphurization.
Air filters are used to prevent damage to power plant equipment through dust particles, contaminants and other harmful particles in the air. The main goal is the maximum absorption of dust particles from the air. Nanofibers with lower thickness and higher specific surface area than that of conventional fibers have many applications in filtration and electrospinning is the most efficient process for production of continuous fibers from synthetic or natural polymers. Electrospinning is used to improve the performance and efficiency of the filter. This technology while increases the efficiency of dust absorption, avoid high pressure drop. Fibers produced by electrospinning have a diameter of less than 100 nm and cover the surface of the filter paper uniformly.
Rainwater pipes are used to transfer the rain and snow water from roof of the buildings. Polyvinyl chloride (PVC) is kind of useful plastics in construction and buildings. By adding lubricants, this material will become softer and more flexible than plastics. If no lubricant and plasticizer is added, UPVC is obtained. Chemical resistance of this polymer makes it interesting for a variety of industries especially pipe industry. Usage of UPVC includes sewer pipelines, water mains and potable water services, power and telecommunication cables. These pipes are supposed to have chemical and corrosion resistance, high elasticity module and toughness, long term tensile strength and abrasion resistance, but they may become brittle exposed to cold atmosphere. In addition, they tend to deform and lose their strength in high temperature conditions. These pipes have been given better properties by addition of nanoparticles.
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.
When using public restrooms, people are often worried about sanitary issues and their related illnesses. People are often sensitive to this issue, so they take special care when using and touching the equipment. Genital infections, fungal infections, skin sensitization and infectious, and microbial diseases are one of the most common causes of these bacteria. This product is an antibacterial squat toilet containing zinc oxide nanoparticles. The antibacterial toilet has surfaces which are resistant to bacterial growth. Sanitary products like wash basin are coated with materials which remove hazardous microorganisms, such as bacteria, viruses, fungi and other germs. In comparison with other metal oxides, the application of zinc oxide in biomedical and antiviral fields is due to its compatibility, solubility in alkaline environments, and terminated polar surfaces.
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.
