In great interest, experts from the most important energy companies held a seminar on reducing Hg emissions by dosing activated carbon. It was divided into two days and they performed in addition to Dr. Pilar from CTU as well as Cabot, Vulcascot, Rataj, FLSmidth Pfister and Aeras. Various methods of mercury oxidation and retention, principles for intensification of EO or TF for increased retention, types, composition and modalities of activated carbon dosing have been discussed. The issue of halogenization of activated carbon, without which the process is ineffective, but high concentration can cause unwanted corrosion of the device. Gravimetric dosing technology was interesting to minimize operating costs through accurate and reliable dosing.
The specifics of individual plants are always important. As Ing pointed out. Václavík: ... The idea that you connect a mobile device, you start dosing activated charcoal and everything will be resolved is completely odd. Each process must be approached individually and respected by its specifics". Dr. Pilař added that based on measurements, the same conditions are not even in different boilers on one site.
Participants of the seminar left satisfied and armed with new knowledge.
Aeras, in cooperation with CABOT, Vulcascot, FLSmidth Pfister and CVUT and VŠB universities, organises on the February 20th a technical seminar on the mentioned topic. If you are interested in the issue, please contact us via the contact form. Participation is free of charge.
Aeras wishes for a beautiful and peaceful Christmas and a successful year 2020 to all its customers, suppliers, business partners, competitors, banking, forwarding, measuring and certification companies, accounting and tax firms and professional periodicals, as well as all other professional and lay public who have been involved in the successful activities of Czech energy and industry in just the past year.
In September, it was possible to commission and pass a cloth filter for Veolia Energie ČR, a.s. into use. The contractual value of TZL emissions was set at 7 mg/m3, with a single verification measurement of about 2 mg/m3. We thank all partners for their assistance in finishing this work, which will reduce the emissions of flying dust in Olomouc.
24. 12. 2018, the Sicilian volcano Etna woke up. By comparing it to other eruptions, we estimate the emissaries of very fine dust (PM 2.5, PM 10) to 2.3 million. tonnes/day. By comparison, the average brown coal-fired power plant meeting the current emission limits with a power of 700-800 MW will release a similar amount of dust in about 100 years of full power operation. Note. We consider the amount of output gas 4.4488 mil m3/h, output concentration 15 mg/m3, 365 days/year of operation.
According to the British newspaper, more than 95% of the world's population breathes polluted air, especially the ever-growing population in cities. Scissors between air quality in developed and developing countries are further open. Since 1990, the gap between the least and most polluted areas has increased from six times to eleven times.
The World Health Organization considers air pollution to be the biggest global environmental problem (more here) with more than six million deaths a year caused by polluted air.
Interesting data is available on the ČHMÚ website. It follows that more than half of the household is most involved in the emissions of flying dust PM2.5 and PM10, followed by a large range of energy and heating, agriculture, road transport and mining.
