There. I am doing my BE project in Ventury scrubber design.As i am from Mechanical background,i have very less info.about this.So if you have previously done excel sheet/pdf of ventury scrubber design then that is very helpfull for me and that gives exact direction to my project work. In fact, the larger the size specification, it means that the scrubber larger the amount of treated exhaust gas is, which is proportional to the price of the wet scrubber. Secondly, another factor that affects the design of the scrubber is the size specification. The paper concerns the analytical research studies on . Scrubbers can also be designed to collect particulate matter and gaseous pollutants. The diameter and height are calculated based on the total air volume and treatment concentration of the exhaust gas. [4] A venturi scrubber employs a gradually . _ b )dv7!RI c n[ )dv7!RIPNG It really makes me wondering why it's very difficult to find detail design information (esp. packing type = intallox saddles packing size = 25 mm packing moc = pp gas pr.

Here basic parameter like temperatue, Pressure, and PH of the coolent takes place. Be aware that low temperature scrubbers can be a potential source for the Legionella disease. Collection efficiency depends on the following factors: 1. and study "Hydrogen Chloride Absorption" in the Chapter "Water as an Absorbent". The larger the scrubber, the more air volume it can handle, and vice versa. By knowing the moisture content of a gas stream . The most appropriate indicators to monitor depend upon a number of factors, including type of pollutant (whether PM is also present), scrubber design, and exhaust gas characteristics. Most of the energy used to operate the system appears as pressure drop across the bags and associated hardware and ducting. With detailed air volume and scrubber diameter data quotations, it can be accurately calculated. Your email address will not be published. Single-layer spray design, the exhaust gas inlet diameter is 500mm, and the total height of the tower can be designed to be 4600mm. ), Since larger flow quantities are at the bottom for an absorber, the diameter will be chosen to. Affect the quotation-structure configuration. The system was a resounding success. Jun 27 Industrial Equipments 17228 Views 24 Comments on Wet Scrubbers. Wet scrubbers control acid gases. Water droplets are separated from the exhaust and re-circulated back to the water reservoir. The gas is then washed with suitable liquid using spray nozzles. Design of Shell Tube Heat Exchanger by Kern Method 2 57 Excel Template. The article is good enough to generate your own excel spreadsheet. The efficiency of a packed bed wet scrubber system can be defined as the effectiveness of the scrubbing process for . 218 mmHg B. Environmental XPRT is a global environmental industry marketplace and information resource. Environmental XPRT is part of XPRT Media All Rights Reserved. Medium-energy scrubbers have pressure drops between 12.7 and 38.1 cm of water. Take the 10,000 air volume tower diameter of 1.4 meters to calculate, with vertical anticorrosive circulating pumps and inlet and outlet pipes. 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 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. Privacy, Our sites: In dust debuggers, dust particles are eliminated from a gas flow by a dispersed liquid. 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. We offer five main customizable designs to satisfy your .51,9,2,1OSOESAG .51,9,2 . We don't collect information from our users. The absorption of gases takes place in the scrubber random packing section and scrubbing liquid is introduced into a liquid through or spray distribution . Fig.2Design methodology for current investigation 3. What is, You have a mixture of 3 gasses with a total pressure of 750 mmHg. Before releasing waste gases that contain PM to the atmosphere, these gases are treated using venturi scrubbers to remove PM.

Please read AddThis Privacy for more information. The higher the configuration, the higher the price of the scrubber. Terms Dust and pollution products from the process are removed periodically through the drain. hQk0W=E Also I haven't yet included the factor of vaporization losses of injected water due to high air temperature. Cyclone droplet eliminator (See KO pot folder for cyclone method). These are common in various industrial applications which includes pollutant reduction at petroleum refineries, the large scale chemical processes, acid manufacturing plants and steel making steel. I am not sure if you can make theoretical calculations for throat velocity of an installed venturi scrubber. After the above, you can be familiar with terminology and use the example of the attachment for a preliminary design, assuming you select a similar packed tower. m/h, how big is the scrubber, and what is the price of the wet scrubber? 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. Based on the equation given in the blog article, you need the inputs to calculate the throat velocity. 8.2.4.4 Wet scrubbers. The larger the size (diameter and height), the more materials and labor costs, and the higher the quotation. Here we reduce the pressure drop of vapor/air and also the temperature before venting with normal water at atmospheric temp.

With the above data, the price of the scrubber is available. Anonymous xrBCp9Ej. Some of our calculators and applications let you save application data to your local computer. This process of saturation results in a change in volume, temperature and density. , , . The inlet gas stream enters to the bottom of the tower and moves upward while liquid is sprayed downward from one or more level. The larger the size (diameter and height), the more material and labor costs, and the higher the price of the wet scrubber. The scrubber is a packed tower with Intalox saddles and is made of Carbon Steel. 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. 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. Studies show that that optimal gas velocity in the throat are from 70-90 m/s. i noticed that the design was based on dry gas,the process i am working on produce a humid air(12%) how can i do the calculation taking account on that . Searching the Web, you can find more information, useful or not (e.g. throat length is calculated to be 2.5 meters, isn't it on higher side a bit?
