Iranian Experts Develop System to Monitor Pollution of Flue-Gas Stacks Rapidly
“Researchers of our company have mass-produced knowledge-based products in the field of monitoring and measuring environmental pollutants, specially in the air pollution sector, and at present, they make 11 commercial knowledge-based products,” said Omid Hosseinpour, a technical expert at the knowledge-based company.
He described the ambient air pollutant station monitoring systems, ambient air particulate sampling device, real-time ambient noise pollution measurement device, portable chimney gas meter (PSGA), online industrial chimney gas meter (PSGA-ONLINE), and portable chimney flow meter (PSFM) as among the achievements of the company.
Hosseinpour described portable industrial flue-gas stack dust monitoring device (PSDM) as another product of the company, and stated, “This device is used to measure the concentration of particles emitted from the chimney of all industrial processes by sampling under aerokinetic conditions, and measuring the parameters of speed, pressure, temperature, humidity, and gas flow rate in the flue-gas stack.”
In a relevant development earlier in December, another Iranian knowledge-based company had also been able to fight against air pollution by producing the most state-of-the-art air filters.
“These filters have been able to remove over 99.9 percent of suspended particles like allergens, viruses and even bacteria, thus providing an efficient solution to ensure health and improve the quality of life,” said Gholamreza Nejad Doost, the managing director of Behineh Sazan Teb Abzar company.
Noting that the air filters are designed with interwoven layers of fiberglass fibers and special polymers to not allow any particles, even as small as 0.3 microns, to pass through, he said, “The accordion structure of these fibers gives them a greater capacity to absorb and retain particles.”
He described the three main working mechanisms of these filters as blockage of the particle path, trapping due to tissue density, and diffusion and dispersion, and said, “The smallest particles are trapped on the sides of the fibers as they pass through, particles larger than 1 micron are trapped in the dense tissue of the fibers, and particles are trapped irregularly in the filter due to collisions with gas molecules.”
