The solution reacts with the acid gases to form salts, which are then collected as a sludge, dewatered, and landfilled. I would be grateful if you can take a look at the excel spreadsheet in which Iam doing these calculations. Wet Scrubbers are air pollution control devices for removing particles and gases from industrial exhaust stream. 1) Corrosion Problems: Generally water and dissolved pollutants can form highly corrosive acid solution. Example: Select the wet scrubber model and give an accurate quotation. There. ruzicastoprase.

If flooding is to be reduced, (i) Select larger packing size and repeat the above steps. Many of you involved in engineering and design of wet scrubbing systems are already familiar with "Venturi Scrubbers". 2) High power requirements: The high collection efficiencies for particulate matter are attainable only at high pressure drops which results in high operating costs. Agriculture XPRT So proper construction materials are very important and wet-dry interface areas can also result in corrosion. 2. A wet scrubber system can be an advantage in controlling both of these emissions. endstream endobj 11191 0 obj <>/Metadata 266 0 R/Outlines 371 0 R/Pages 11188 0 R/StructTreeRoot 3184 0 R/Type/Catalog/ViewerPreferences<>>> endobj 11192 0 obj <>/ExtGState<>/Font<>/ProcSet[/PDF/Text]>>/Rotate 0/StructParents 0/Tabs/S/Type/Page>> endobj 11193 0 obj <>stream But since you have responded to the OPs request, Ill go ahead and comment on your query.

Here we reduce the pressure drop of vapor/air and also the temperature before venting with normal water at atmospheric temp. Since wet scrubbers vary in complexity and its method of operation so we divide it in following categories. Affect the quotation-structure configuration. Take the 10,000 air volume tower diameter of 1.4 meters to calculate, with vertical anticorrosive circulating pumps and inlet and outlet pipes. packing type = intallox saddles packing size = 25 mm packing moc = pp gas pr. Thank You sir, The information you have provide in the blog is correct. Low-energy scrubbers have pressure drops of less than 12.7cm of water. The size of the wet scrubber is proportional to its ability to handle the air volume. Scrubber Wet Stack Design Guide. These equations are a good approach for particulates, but they do not describe absorption of volatiles or high solubility gases. The calculation method is to disassemble the plates. [4] A venturi scrubber employs a gradually For dimensioning purposes, and to evaluate the workings of a scrubber, it is important to know how much liquid is required per m to realise the required residual emission. Existing wet scrubber systems may meet the new standards with significant increase in power consumption. Required fields are marked *. endstream endobj startxref Medium-energy scrubbers have pressure drops between 12.7 and 38.1 cm of water. The design of the wet scrubber is based on the diameter and height of the scrubber, and the diameter and height are calculated according to the total air volume and treatment concentration of the exhaust gas. The scrubbing media used is water with 6% NaOH and the fluid to be scrubbed is a HC with a MW of 36.6 at 111 C and 1,000 ppm of HCl. Design data: The liquid-gas ratio (L/G) in a scrubber is the relationship between the scrubbing liquid flow rate and the gas stream flow rate. If the customers workshop has a designed exhaust volume of 10,000 cubic meters per hour, and the designed flow rate through the empty tower is 2 meters per second, the diameter of the scrubber will be 1.33 after calculation. 3) Water-disposal problems: The settling ponds or sludge clarifier is needed to meet waste-water regulation meter.

This technology is otherwise known as the water scrubbing technology. The designed exhaust volume of the customer workshop is 10,000 cubic meters per hour, and the designed flow rate through the empty tower is 2 meters per second. Terms Collection efficiency depends on the following factors: 1. The higher the configuration, the higher the price of the scrubber. By using water eliminates the probability of explosions. The wet scrubber will handle dirty gas streams by mixing water or water solutions with the air or gas and transferring the solids or soluble gases to water. A schematic drawing of a typical spray nozzle scrubber configuration is shown below. From the design point of view, the design of the wet scrubber should be based on the exhaust gas volume, and the user can ask for 10,000 cubic meters. The typical wet scrubber system consists of a scrubbing vessel, a duct-work and fan system, a mist eliminator, a pumping, a spent scrubbing liquid treatment and an exhaust stack. Dust and pollution products from the process are removed periodically through the drain. Secondly, another factor that affects the price is the size specifications. Engineering and Application data is presented. Wet scrubber design calculation method The scrubber is selected and the price of the scrubber is given.

Based on the equation given in the blog article, you need the inputs to calculate the throat velocity. After calculation, the diameter of the scrubber is 1.33 meters. China Xicheng EP Ltd. After receiving the quotation for thewet scrubber, the customer often puts forward the quotation is too high, so many customers do not know the scrubber, but habitually give the conclusion that the price is too high, it seems that something is wrong, the technical team will pass the data Provide detailed basis and configuration of wet scrubber quotation. ) _-* #,##0_-;\-* #,##0_-;_-* "-"? Venturi scrubber calculator solving for estimated pressure drop given gas velocity and water to gas volume ratio. This method is similar to that used by Hollands and Goel (1975) to obtain pressure drop in venturi scrubber. Normally I would advise you to post your query on your scrubber design in a new, independent thread within this Forum in order to address it separately from the topic in this thread. Thanks sir for the valuableinformation, however please guide me a bit further as I am designing a venturi scrubber for removal of particulate matter (218 mg/m3)from air at 1.6 m3/s. The operating pressure varies between 0.3 - 0.9 barg. High-energy scrubber have pressure drops greater than 38.1 cm of water. 8.3 Use performance evaluation equations to determine efficiency of wet scrubber mechanisms. The SSM was optimized as a hexagonal scrubber column with a diameter of 45.7 cm (18 in.) Scrubbers can also be designed to collect particulate matter and gaseous pollutants. If the gas pressure in the container has, During a performance in an airshow, a 593 kg stunt plane makes a circular horizontal turn of radius 81 meters. This issue is important due to the use of the Venturi scrubbers in the syngas cleaning process. Classification of Packed-Bed Wet Scrubbers.

The most common mist eliminators are chevrons, mesh pads, and cyclones. It removes all air pollutants by inertia of diffusional impaction and reactions with absorbent or reagent slurry or absorption into a liquid solvent. Users can ask about 10,000 cubic meters per hour. The WH High Energy Scrubber is a high pressure drop, very high efficiency wet dust collector with an adjustable throat venturi. The thickness of the scrubber bottom plate is 12mm, the thickness of the tower body is 8mm, and the wall thickness of the water tank is 10mm. CO 2) By product . The company's first project in the early 1970's was a pilot venturi scrubbing system designed to remove oil and particulate from a contaminated air stream at an automotive manufacturing plant. Calculation method of wet scrubber quotation Example: Select the wet scrubber model and give an accurate quotation. Increase in Liquid-to-gas Ratios increases the collection efficiency. Wet scrubbers are usually the most appropriate air pollution-control device for collecting both, particulate and gas in a single system alone.
