Scrubber for cleaning of exhaust gases, absorption technology with NaOH solution

wet scrubber

Rus На русском Eng In English

Application requirements. Scrubber is designed to “wash out” unwanted pollutants, like dust or sulphur dioxides from industrial exhaust Scrubber for cleaning of exhaust gases: general view and operating schemestream, created in the process of dispersed carbon-contained material burning out in the waste-heat boiler of the furnace for 1 tone/h.

Scrubber frame is designed for gas flows and water droplets organizing.

Irrigation system is designed for water supply and spraying inside the scrubber.
Sludge removal device is designed for sludge automatic removal from the scrubber.

Emergency water supply system is designed to cut off water supply if sludge removal from the scrubber is impossible. The inner surface of the scrubber should be resistant to corrosion under the influence of lean solution of sulfuric acid.  The scrubber frame shall have openings for maintenance work.  The frame must have a split body design to allow for repair work if necessary.The scrubber frame should have one or several technological openings (man-holes) providing for the unit maintenance (control of the surfaces general state, spay nozzles replacement, frame renewal etc). Spray nozzles should be replaceable.

Operating requirements. Gas with pollutants is fed along the inclined gas flue to the bottom of the scrubber and then goes up.

On the top of the scrubber there are centered spray nozzles spaced in 3 tiers.

NaOH solution supplied under pressure is irrigated. Formed water droplets fall under the gravity force towards dustiness gas stream. They fall onto the perforated plates where bubbles and interaction of gas with solution takes place. Washing out of gas stream from sulfur oxides is based on absorption technology. The following reaction takes place when NaOH solution contacts with gas:
2NaOH+SO2→Na2SO3+H2O
NaOH+SO2→NaHSO3
2Na2CO3+SO2+H2O → 2NaHSO3
2Na2CO3+SO2 → Na2SO3+CO2
Processed solution and captured dust are gathered in the scrubber bottom part. Clean gas is discharged through the inclined gas flews, placed in the scrubber upper part.

Manufacturing of the scrubber: metal cutting, welding, argon welding, milling processing and assembling

Spray-On Antennas Could Be the Tech Connector of the Future

Invisibly thin MXene antennas can be applied to a variety of substrates and perform better than antenna materials currently used in mobile devices.

Now, researchers at Drexel University have developed a method for creating nearly invisible antennas on almost any surface by literally spraying them on like paint. The antennas are made from a special two-dimensional metallic material called MXene. MXene powder can be dissolved in water to create a paint that is then airbrushed on. In tests, even a layer as thin as just 62 nanometers – thousands of times thinner than a sheet of paper – could communicate effectively. Performance maxed out at just 8 microns, a point at which the spray-on antennas worked just as well as those currently used in mobile devices and wireless routers.

 
Congratulations to professor Yury Gogotsi, professor Rodney S. Ruoff and professor Patrice Simon with being named by Clarivate Analythics among of the 17 most cited and influenced world-class scientists in 2018!

Professor Yury GogotsiThis designation celebrates researchers whose influence is comparable to that of Nobel Prize recipients, as attested by exceptionally high citation records within the Web of Science.

MXene is one of the most sensitive gas sensors ever reported

MXene gas sensorsMXene is one of the most sensitive gas sensors ever reported that sniff out chemicals in the air to warn us about everything from fires to carbon monoxide to drunk drivers to explosive devices hidden in luggage have improved so much that they can even detect diseases on a person’s breath. Researchers from Drexel University and the Korea Advanced Institute of Science and Technology have made a discovery that could make our best “chemical noses” even more sensitive.
