Scrubber Design Calculation Excel Hot Jun 2026

This article guides you through the step-by-step math, core chemical engineering principles, and Excel formulas needed to design a high-efficiency packed bed or venturi scrubber for hot gases. 1. Characterize the Hot Inlet Gas

Often, a "quench" section is placed before the packing to reduce the gas temperature to adiabatic saturation before it enters the packed section. This protects the packing.

: Hot gas often requires exotic alloys or specialized FRP (Fiber Reinforced Plastic). Ensure your Excel includes a "Material Factor" lookup table.

Disclaimer: Scrubber design should always be verified by a licensed professional engineer (PE) to account for specific system dynamics and safety factors.

Temperature (°C or K), Pressure (atm or Pa), Flow rate (Nm³/h or kg/s), Pollutant concentration (ppm or g/m³).

Create these mandatory input cells:

This sheet handles the thermodynamics of the hot-to-wet conversion.

By mastering these tools and following a step-by-step approach, engineers can quickly and accurately size a scrubber for initial project estimates, feasibility studies, and process optimization. However, it is essential to remember that these spreadsheets are a starting point. Their true power is unlocked when their preliminary designs are validated with real-world vendor data and professional engineering judgment, ensuring the final system is safe, compliant, and efficient.

Designing an industrial gas scrubber requires precise thermodynamic and aerodynamic calculations. When dealing with hot gas streams—such as incinerator flue gas, kiln exhaust, or furnace emissions—the design complexity increases. Hot gases undergo significant volumetric contraction upon entering a scrubber due to rapid evaporative cooling. This article guides you through the step-by-step math,

Dedicate this sheet entirely to user inputs. Use explicit cell highlighting (e.g., light blue) for cells the user is allowed to modify. Inlet flow rate ( kg/hrkg/hr ), inlet temperature ( ∘Craised to the composed with power C

Pressure drop is critical for fan sizing and operating cost. This module includes:

Ensure the Excel sheet flags an alert if the inlet temperature exceeds the thermal limit of standard materials like FRP (Fiberglass Reinforced Plastic).
