| Scrubber Type | Typical L/G Ratio | Application | |---|---|---| | Spray tower | 0.5–2.5 L/m³ | Particulate removal, simple gas absorption | | Packed bed | 0.3–1.5 L/m³ | Gas absorption (SO₂, HCl, NH₃) | | Venturi | 0.5–2.5 gal/1,000 ft³ (≈0.07–0.33 L/m³) | Fine particulate collection | | Cyclonic scrubber | 1–3 L/m³ | Combined particulate and gas removal |

The MDSJ Process engineering tool notes that for optimal L/G ratio: “Too low = insufficient contact area; too high = unnecessary energy consumption”.

. Using Excel allows for iterative modeling of these complex thermal and chemical interactions. www.mchip.net Core Design Parameters

| Scrubber Type | Key Design Outputs | |---------------|--------------------| | | Throat velocity (60–120 m/s), pressure drop (based on Johnstone eq.), liquid-to-gas ratio (L/G) | | Spray Tower | Sauter mean diameter (SMD) of droplets, tower height, gas residence time | | Packed Bed | Packing factor (Fp), flooding % (≤75%), pressure drop via Leva or Eckert correlation | | Tray (Impinement) | Number of trays, slot velocity, weir loading | scrubber design calculation excel hot

), not the hot inlet flow rate. The sudden drop in temperature decreases gas volume, but the added evaporated water vapor increases it. 2. Determine Liquid-to-Gas ( HCL Packed Bed Scrubber Design Guide | PDF - Scribd

Assuming a stoichiometric ratio of 1.5 and a NaOH solution density of 1,000 kg/m³:

$$ \textMolar flow rate of SO2 = Q \times C \times \frac110^6 \times \fracPR \times T $$ | Scrubber Type | Typical L/G Ratio |

$$ L = \frac223.2 \times 1.540 \times 1000 = 8.37 , \textm³/h $$

The throat velocity must typically range between 60 m/s to 120 m/s (200–400 ft/s) for effective atomization.

Calculate tower cross-sectional area and round up to standard industrial pipe or vessel diameters. Section 4: Outputs and Performance Summary Determine Liquid-to-Gas ( HCL Packed Bed Scrubber Design

Maintaining a low pressure drop is essential to manage operational energy costs. A standard design target is between (

Y=0.622×PwPtotal−Pwcap Y equals 0.622 cross the fraction with numerator cap P sub w and denominator cap P sub t o t a l end-sub minus cap P sub w end-fraction Pwcap P sub w

Entering gas at high temperatures can crack standard fiber-reinforced plastic (FRP) or ceramic scrubber internals. Ensure your spreadsheet flags inlet temperatures above 250∘C250 raised to the composed with power C

To build a reliable verification sheet for hot gas scrubber design, organize your Excel workbook into three distinct sections: , Thermodynamic Iteration Engine , and Sizing Outputs . Section 1: Input Parameters
