The process of contacting the gas and liquid streams results in entrained droplets, which contain the contaminants or particulate matter. They are used . Selection of packing material. [How to] Prepare Operational qualification ? Packing MOC                                 : PP, Gas pressure drop per m of bed : 15 mmWC /  m of bed, [Considered Value], Packing factor, Fp                          : 21 / m, [Considered value]. Through a nozzle or orifice a scrubbing liquid is atomized and dispersed into the gas stream. engineering standard for process design of vacuum. HiSir how to calculate the hcl scrubber capacity. Contraction losses = 1.5 x v^2/2gc = 1.5 x (6^2/(2 x 1)) = 27 N/m2. So, now we have determined total of three flowrates for the gas. Each of these has their own considerations, such as throat diameters, bed-packing materials and high-pressure liquid choices, respectively. It is also hypothesized that the packing provides large interface area for the contact of liquid and gas phase inside the packed bed. fzhou. As the saddles would be cheap, for ensuring cost effectiveness, i'm considering intallox saddles. : 29 g/mole. Now we have to estimate all four, to get the overall pressure drop. Considering 60% efficiency, 0.1533/0.6 = 0.255 KW = 0.34 HP. The scrubbing efficiency is the key performance of the packed bed scrubber system. Using the above curve and plotting the flow-factor of ~0.01 at 15 mmWC curve(based on initial assumption). This is to be expected as there are so many variables to consider when going through various options, including venturi, packed-bed, or eductor venturi wet scrubbers. : HCL Scrubber Checked by : Job No. There are majorly 4 major components according to me. Nazia Shahid. So, an itemized breakdown of the cost can help you understand what you are budgeting for. Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! and specified worldwide. Required blower capacity = Hydraulic power x 1714 / (0.1771 x blower efficiency). In normal condition, wet scrubbing is used to remove HCl, which is one of the acetic gas. wet scrubber, 8300 Dow Circle, Suite 600 Strongsville, OH 44136, How to Determine Wet Scrubber Costs for Your Next System Design, Monitoring equipment including pressure gauges, airspeed sensors, humidity detectors, and temperature monitors, Water flow, pressure, and quality sensors, Storage tanks, recirculating tanks, and recirculating pumps, Water supply piping, and recirculating piping, solutions were used to solve similar problems. wet scrubber technology. Most manufacturers will have customer case histories they can share with you or references you can call yourself with questions you would like to ask. Although they can also collect solid particulate matter, Packed-Bed scrubbers are generally used more for the treatment of gas. Figure 41.1 shows estimated size for some common pollutants. between 0.5 and 5.0 micrometers in diameter. Ask your vendor questions such as: Where can I find an installation of a similar size, with similar particulates, in a similar or same industry as my application? [How To] Design a Scrubber [ Packed column ] (UPDATED) as on 07.02.2020. For scrubbing HCl fumes, i've selected Caustic solution 20%, but i should be able to calculate the theoretical amount of caustic required in this case. Wet scrubbers are usually the most appropriate air pollution-control device for collecting both, particulate and gas in a single system alone. The safety valves discharge to the scrubber and the scrubber overhead vapor discharges to the flare system. Total Pressure drop = 441.3 + 157.07 + 245.17 + 27 = 870.54 N/m2. [(G' ^ 2) x Cf x (μl^0.1) x J ] / [ρg(ρl - ρg)gc] = 0.04 [from graph], Now, Outlet flowrate of gas through the column (. So, i would like to perform the material balance: Liquid flow rate       : 77 Kg/hr = 0.0214 Kg/sec. 1. in atm) x (22.414/1). In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid, by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove the pollutants. It just means there’s more to consider when building your budget than the scrubber unit itself as the only cost. Dear Sir, 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. "#˝& A 24 ton/day Flue gas flow rate : 5 Nm.3/sec. Both gas and liquid streams are mixed and HCl is transfer from gas phase to scrubbing liquid phase. Flue gas temp. ρl)^0.5 = (0.0420/0.2778) x (1.1846/1100)^0.5 = 0.00497. saddles. Types of scrubber units 31 30/12/2014 Wärtsilä Environmental Solutions Scrubber with venturi • SOx reduction from 3,5% to 0,1% • PM reduction up to 80% • By-pass needed • Existing silencer recommended to be kept Inline scrubber • Smaller footprint • No by-pass – can run hot • Pressure drop at design: 150 mm WG • SOx reduction If any concern, pl do feel free to comment / contact. Caustic Scrubber Designs for H 2S Removal from Refinery Gas Streams . Ideal column cross sectional area = Inlet gas flow / mass flowrate = 0.2778 / 3.01 = 0.0922 m2, Actual flooding = Ideal flooding x (Actual cross sectional area / Ideal cross sectional area), As per Norton correlation, Ln HETP = n - 0.187 x Lnσ - 0.213 x Ln μ, = 1.1308 - 0.187 x Ln 80 - 0.213 x Ln 1 [. The wet scrubbers discussed in this chapter use water to remove particulates, gases, or both from industrial gas streams or stacks. Solving for estimated pressure drop. = 870.54 x (0.2778 - 0.0207) / 1.46 = 153.29 N.m/sec = 0.1533 KW. of theoretical stages required = Total height of packing bed / HETP = 3/0.416 = 7.21 ~8 stages. wet scrubber application guide sly inc. instruct uwo ca. When building a budget for the project, not only do facilities engineers and operations staff have to consider the many equipment options available, but they also have to keep in mind their in-house engineering, installation and ongoing maintenance capabilities. This process of saturation results in a change in volume, temperature and density. Tri-Mer packed scrubbers are highly recommended for the . = [0.6 x 1.1846 x (1100 - 1.1846) / (13.1 x 21 x (0.01/1100)^0.1]^0.5 = 3.01 Kg/m2.sec. System capacities of heavy service V/F systems range to 100,000 cfm and above. : 4506A Date : Client : JOL Project : SR - Plant -4, 5 ###Input Data Stream : HCL Vap. Using the same basic design, these standard scrubbers can be sized to meet volume requirements from a few CFM to thousands of CFM. Math Geometry Physics Force Fluid Mechanics Finance Loan Calculator. Hi! Considering all the variables involved—associated components, the cost tradeoffs of turnkey vs. in-house-designed systems, and the difference between initial purchase price and total cost of ownership—will help you create a complete and accurate understanding of the true costs of a wet scrubber system. The droplets entrain and capture dust particles through agglomeration, adherence, or encapsulation. Wet Scrubber Lesson01. You might be interested in: Air Scrubbers, Wet Scrubbers and Gas Scrubbers, Manufacturing Operations Management Software (MOM), Scrubbers . 6.3, and J is conversion factor, you can take it as 1.0, which is adequate for liquid distribution and irrigation across the bed.Next time, kindly comment with you name .Regards,AJAY K, Hi Ajay, How can you taken scrubbing agent flow rate as 77 Kg/Hr.In my plant we are using 10 m3/Hr centrifugal pump for transfer lye solution from lye tank to scrubber absorption column.
